Narrative:Supplemental Information
Befesa Mooresboro, NC Effluent Discharge Permit Renewal Application
Permit NC0089109
This renewal application is submitted to the North Carolina Department of Environmental Quality(NCDEQ) for
timely renewal of the effluent discharge permit (Permit NC0089109) for the Befesa Mooresboro, NC facility
("the facility"), formerly American Zinc Products, LLC. See Form 1 attached for site information.
Information provided in this permit renewal application includes effluent discharge monitoring data collected
for Outfall 001 from June 2020 to August 2022 (See Form 2C—Section 1 Attachments for outfall location).
Monitoring was performed in accordance with permit requirements for analytical monitoringof
Y discharged
effluent. Information provided in this permit renewal application reflects effluent discharge monitoring data
provided in monthly discharge monitoring reports (DMRs) submitted to the Department from June 2020 to
August 2022.This information reflects the nature of effluent discharge water based on current operations.
A summary of effluent flow and characteristic information is provided below. Data from Monthly DMR's for the
past 26 months from June 2020 to August 2022 are provided in the tables in the Form 2C-Section 7
Attachments of this narrative.
Facility Description
The manufacturing process at the facility consists of an integrated system of leaching, solvent extraction, and
electrowinning processes. This facility replaced a former zinc smelter. Feedstock for the Mooresboro facility,
including metal bearing oxides and other raw materials, is managed in solution throughout the process.
Valuable metal products are removed as precipitates,concentrates, and high-grade zinc metal. As detailed on
the water flow line drawing included in the Form 2C—Section 2 Attachments,the facility differs from a
traditional definition of a process facility with wastewater effluent as there is no wastewater treatment system.
Removal from the process streams of what would otherwise be considered pollutants represents the generation
of commercial products for this facility.
Process units described on the line drawing extract valuable metals and products, most of which are listed as
effluent discharge parameters. Once all cost-effective metals extraction is achieved,the resulting process
wastewater stream requires no further treatment to comply with the categorical effluent standards applicable
to the discharge. These process cycles are all inherent to facility operations. The uniqueness of the facility is
made clear in the fact that it is only one of three facilities in the world that performs these processes.
Permit History
NPDES Effluent Discharge Permit No. NC0089109 ("the permit" or"the current permit") was issued to AZP for
the discharge of process water effluent to the Broad River on June 9, 2020, effective July 1, 2020, and expiring
July 31, 2023. On September 20, 2022,the facility's name was changed to Befesa Zinc Metals, LLC.
NCDE DW
Q/ Q was notified of this change via a Name Change Form.

In addition to this permit,the plant has two additional NPDES Permits:
■ NCG500677 issued by NCDEQ on January 6, 2021 -Certificate of coverage for discharge of non-contact
cooling water, cooling tower and boiler blowdown, condensate, exempt stormwater, cooling water
associated with hydroelectric operations, and similar wastewaters under the DEQ's General Permit
NCG50000.
Currently this plant continues to route these discharges through the stormwater outlet. Befesa has plans to
reroute this water back into the process where it can be reused. This modification is planned for calendar
year 2023 and is not anticipated to impact the parameters in this permit.
■ NCS000562 Issued by NCDEQ May 2, 2018,for the discharge of stormwater to the Broad River.
Fish Tissue Study
The fish tissue study required by Section A.4 of the permit in the Broad River was performed in the summer of
2022. Results have been reported to NCDEQ electronically. A copy and summary of the results have been
included here for reference in Appendix 2.
Discharge Volume
The current permitted monthly average discharge volume is 980,000 gallons/day (0.980 MGD). As the facility
production has increased over the current permit period,the effluent discharge volume has also increased
accordingly while staying within the 0.98 MGD limit. The reported maximum monthly average discharge volume
is 0.957 MGD with the monthly average for the permit period being 0.875 MGD.
While the monitoring data summarized in Form 2C Section 7 and in this narrative includes data from the start of
the permit period (June 2020)to present,the average monthly discharge of 0.875 MGD is only based on flow
data back to January 2021. It was determined that the lower monthly average flows from the ramp up
production period are not representative of the facility flow (i.e.,flows mostly below 0.80 MGD).
Effluent Limitations and Monitoring Requirements
As is now required by NCDEQ, EPA Forms 1 and 2C were completed for the facility, an existing industrial facility
discharging process wastewater. The facility has met its permit limits for flow, pH, and Total Cadmium. The pH
limits of>_6 SU and 5_9 SU were not exceeded per the daily averages recorded,the minimum daily average being
6.44 and the maximum daily average being 8.34. The Total Cadmium monitoring is discussed in further detail
later in this narrative as it pertains to the Cadmium Compliance Schedule.
The facility is requesting a waiver for the following parameters, as was done for the last permit:
■ Biochemical Oxygen Demand (BOD5)
■ Chemical Oxygen Demand (COD)
■ Total Organic Carbon (TOC)
■ Temperature (winter)
■ Temperature (summer)
2

The facility still has reason to believe that BOD5, COD,TOC, and temperature are not pollutants of concern
significantly present in the effluent because of the nature of the facility operations. There are no sources that
would contribute levels of these parameters with a reasonable potential to exceed water quality standards in
the effluent discharge.
Tables A through E in Form 2C were completed with quantitative results listed for those pollutants/parameters
for which testing is required per the current permit. This includes those listed in the permit requiring quarterly
or more frequent monitoring as well as the Priority Pollutants listed in Section A.5 of the permit. The permit
does list parameters under the Section A.5 Priority Pollutants Analysis corresponding to pollutants/parameters
in Table B Sections 1 "Toxic Metals, Cyanide, and Total Phenols", Section 2 "Organic Toxic Pollutants (GC/MS
Fraction—Volatile Compounds)", Section 3 "Organic Toxic Pollutants (GC/MS Fraction—Acid Compounds)", and
Section 4 "Organic Toxic Pollutants (GC/MS Fraction—Base/Neutral Compounds)". While the facility does fall
into the Nonferrous Metals Manufacturing category and Form 2C indicates that the facility is required to
monitor for pollutants in Table B Section 5 "Organic Toxic Pollutants (GC/MS Fraction—Pesticides)", none of
these parameters were required by the previous permit and have not been analyzed. They are all believed
absent from the facility with no reasonable potential to be present.
There are two pollutants noted in Form 2C as "believed present" where no quantitative data were reported:
Sulfide (as S) and Surfactants in Table C. These are not monitored by the facility currently and were not required
in the previous permit. Sulfide is believed present in the effluent as sodium sulfide is used in the process as
precipitating reagent. Surfactants are believed present in the effluent due to a flocculant is used in final solid-
liquid separation step of the process.
Cadmium Compliance Schedule
The Cadmium Compliance Schedule (CCS) set forth in section A.6 of the current permit has a deadline to achieve
full compliance as December 1, 2027. The compliance limits in the current permit for Cadmium are a monthly
average of 350.0 µg/L and a daily maximum of 2,143 µg/L. The compliance limits for Cadmium at the
completion of the CCS are a monthly average of 90.4 µg/L and a daily maximum of 454.4 µg/L. These CCS
compliance limits have been consistently met by the facility, acknowledging only two exceedances in the last
permit period. Please see Appendix 1 for a detailed compliance evaluation and justification. The facility is
proposing that full compliance has been achieved and,therefore, is requesting the removal of the CCS from the
permit.

The facility was approved in June 2020 to commence production of Zinc at the Mooresboro facility with
an initial ramp up in production expected to be 75% production capacity by December 2020. Following
the initial ramp up, Befesa was to begin an evaluation period for permit compliance with the cadmium
discharge limits through June 2022. The CCS evaluation period ended on June 1, 2022, with additional
activities required to be performed through December 1, 2027, as stated within the CCS. The next step
of the CCS, as required by the permit, is for the facility to prepare and submit for review and comment a
Preliminary Engineering Report (PER) of process alternatives and/or pollution prevention/waste
minimization alternatives to achieve future compliance standards. The PER is required to be completed
by December 2022.
Information provided within this permit renewal application includes effluent discharge monitoring data
provided in monthly discharge monitoring reports (DMRs) submitted to the Department for Outfall 001
since June 2020 (See Form 2C—Section 7 Attachments). Monitoring was performed in accordance with
permit requirements for analytical and monitoring of discharged effluent. This information reflects the
nature of effluent discharge water based on current operations and flows relating to the Total Cadmium
present in the discharge.

Section 2
Regulatory and Permitting Overview
2.1 Monitoring Requirements and Effluent Limitations
The next required step of the CCS is to prepare a Preliminary Engineering Report(PER) of process
alternatives and/or pollution prevention/waste minimization alternatives to achieve future compliance
standards. Under the current permit,the facility has an interim monthly average discharge limit for
Total Cadmium of 350.0 µg/L with a daily maximum of 2,143.00 µg/L. Final limits established by the
permit indicate that concentration limits are to be reduced to a monthly average of 90.4 µg/L with a
daily maximum of 454.4 µg/L when ramp up of production is complete.

As shown on Table 2 above, monitoring results indicate that the facility is meeting not only the current
interim effluent discharge limits, but also the final limits proposed for a 75% production rate (per
activity 2 of the CCS). The facility has attained this discharge while at a 97%total production rate. The
effluent discharge monitoring data represents Outfall 001 since June 2020. Additional monitoring data
may be reviewed within Form 2C—Section 7 Attachments of the permit application.
2.2 Effluent Flow and Discharge
Currently,the facility has reached 97%of its production capacity. The permit limits process flow to a
monthly average of 0.98 MGD. The daily maximum flow to date has been 1.393 million gallons a day
(MGD). The facility is currently experiencing an average monthly discharge 0.875 MGD, 89% of the
permitted limit.

Flow Monitoring Results 0.875 MGD 1.393 MGD Continuous
There are two additional process flow ramp ups activities scheduled as part of the CCS, however the
facility has limited capacity for further ramp up of its production process. Flow data indicates that the
facility now averages less than the permitted flow requirements, at cadmium concentrations lower than
required and is near maximum production capacity, with limited production increases planned in the
future.
As expressed in the NPDES permit issued on June 9, 2020, Permit No. NC0089109,the facility is required
to meet interim Total Cadmium limits with final limits expressed in the permit as ramp up of the facility
occurs over the permit term, see Table 2 above. As part of the permit,the facility is required to meet a
CCS in order to achieve compliance with final limits. The facility monitoring results, since June 2020,
indicate monthly averages and daily maximum levels of total cadmium in the discharge are consistently
below the final effluent limits. See Table 4 on the following page for sampling results over the permit
term.

Conclusions
As described within the CCS,the facility shall evaluate process alternatives to achieve compliance with
permit limits. The facility is currently achieving compliance with the final effluent limits at current
production rates and is requesting removal of the future CCS requirements and removal of the CCS from
the renewed permit.
The daily maximum and monthly average of cadmium in the facility's discharge indicate a daily
maximum of 130 µg/L, well below final effluent limits daily maximum of 454.4 µg/L. The facility under
current operating conditions has an allowable discharge rate of 3.716 lbs/day of Cadmium utilizing its
maximum average monthly flow and future effluent limits. Considering the facility's current average
monthly discharge rate of 0.875 MGD and the lower average monthly cadmium discharge
concentrations of 90.4 µg/L, operations indicate that it may be feasible to request either a flow increase
to allow for further production or a release from additional compliance schedule requirements since
these parameters have routinely been achieved since the effective date of the current permit in 2020.
The facility process is a refining process where treatment units are inherent to its process and intended
for recovery of product rather than wastewater treatment intended to meet effluent guidelines. As part
of the CCS,the Preliminary Engineering Report is required to provide process alternatives or waste
minimization to achieve compliance while the facility increases flow to full production capacity. The
facility effluent monitoring indicates that additional process or minimization is not necessary to meet
permit requirements. Befesa is therefore requesting that no further action be required related to the
CCS and that it be removed from the permit upon renewal.

Section I
Introduction
Part 1, Condition A.(4) of National Pollutant Discharge Elimination System (NPDES) Permit NC0089109
issued to American Zinc Products (AZP), LLC, requires AZP to conduct fish tissue monitoring once during
the current permit cycle.. In response, AZP developed a fish sampling plan for their facility located in
Mooresboro, Rutherford County, North Carolina (Figure 1). The sampling plan was submitted to the
North Carolina Division of Water Resources (NCDWR) Water Quality Permitting Section and Water
Sciences Section for review and comment. Comments were addressed in a Revised Fish Tissue
Monitoring Plan (Plan) submitted to NCDWR on April 16, 2020, and approved on May 5, 2020. The
approved Plan is included as Attachment A to this report. The primary component of the Plan requires
collection of fish tissue for evaluation of arsenic, cadmium and zinc(i.e.,target metal) concentrations.
TRC Environmental Corporation (TRC) was contracted by AZP to advise, coordinate, and oversee
implementation of the Plan in accordance with the permit requirements. EA Engineering, Science, and
Technology, Inc., PBC (EA) performed the in-stream fish tissue collection efforts.
This report presents-results of the fish tissue sampling effort and the fish tissue analytical results to
satisfy requirements of the NPDES permit. Fish tissue sample collection efforts were conducted in the
Broad River, Rutherford County, NC,at locations upstream and downstream of AZP's permitted discharge
outfall in accordance with the NPDES requirements and the approved Plan..

Section 3
Project Overview
The primary objective of the fish tissue collection effort was to fulfill the NPDES permit fish tissue
monitoringcondition
ition requirement.
t. The q permit requires collection of fish tissue samples from two
locations (upstream and downstream of the AZP discharge point in the Broad River) for analysis of
arsenic, cadmium and zinc.
The upstream fish tissue sampling station is within North Carolina Stream Index Reach 9-(25.5)which is
classified bythe State to as WS IV. Class WS-IV waters are those used as sources of water supply
ppy for
drinking, culinary or food processing purposes where a WS-I, II, or III classification is not feasible. The
downstream fish tissue sampling station is within North Carolina Stream Index Reach 9-(36.5), which is
classified by the State as "C". Class C waters are those protected for uses such as aquatic life
propagation, survival and maintenance of biological integrity (including fishing and fish), wildlife,
secondary contact recreation, and agriculture.
The Broad River is a rocky,flashy, and swift waterbody capable of rapid changes in water flow and
depth. As such, site-specific sampling considerations were discussed in detail with the sampling team.
Prior to implementation of the tissue sampling program, EA developed a detailed Standard Operating
Procedures (SOP; April 2022) which integrated the NCDEQ approved Plan with site-specific
considerations and additional details of the sampling and analysis program implementation. TRC and
AZP reviewed the SOP for completeness and consistency with permit requirements prior to study
implementation. The SOP provided additional details on sample locations, sampling schedule, collection
methods, target species, sample processing and handling procedures and custody details. Attachment B
includes EA's Standard Operating Procedures(SOP)Standard Operating Procedures for NPDES Permit
(#NC0089109)Required Fish Tissue Collection(April 2022). EA obtained a Scientific Fish Collection License
(Permit Number 22-SFC00267)from the North Carolina Wildlife Resources Commission (NCWRC)that
specified the designated species, numbers of specimens, collection methods, and sampling locations.
g
A site reconnaissance was performed on March 22, 2022, to evaluate access points along the Broad
River study area. Both upstream and downs
tream access points were evaluated and identified during
the reconnaissance. AZP obtained landown
er permission for the
he reconnaissance access to evaluate
upstream and downstream access locations.
A sampling schedule was developed based on multiple site considerations including river stage. United
States Geological Survey(USGS) stream gaging Station 02151500,Broad River near Boiling Springs,
North Carolina, was utilized to monitor river stage and discharge conditions. AZP provided turbidity
readings to gauge water clarity during the sampling window. Sampling was conducted during May 2022
to target river levels and turbidity observations that would be optimal for sampling conditions.

Section 4
Summary of Fish Tissue Collection Efforts
Fish tissue sample collection was conducted from May 16 to May 22, 2022. Fish tissue samples were
collected from two locations on the Broad River, upstream and downstream of the AZP facility
(Figure 2). The upstream location extended from the Jack McKinney Road Bridge to approximately one
mile downstream of the bridge. The downstream location began near the Highway 221 Bridge and
extended approximately one mile downstream from the Highway 221 Bridge.
The project area is in a mixed forested, industrial, agricultural, and commercial property use area.
lnstream cover in the sampling locations on the Broad River was a combination of logs and woody
debris, rocky shoals, overhanging vegetation, and undercut banks. Two primary access points were
identified and utilized with access permissions in place. The primary collection method utilized was in
stream boat electrofishing. Gill nets were also deployed during the sampling effort. Attachment C
includes a photo log from the sampling event (presented in Appendix D of Attachment C).
The Plan identified three target species representing the following three separate troph
ic levels:
largemouth bass (Micropterus salmoides),top predator, redbreast sunfish (Lepomis auritus), mid-trophic
insectivore, and notchlip redhorse (Moxostoma hic omnivore. The minimum target
collapsum), mi p
p
number of individual fish was six of each species and the maximum was 10 individuals of each species,
from each sampling location. The Plan provided for substituting secondary species if target species were
not encountered in appropriate numbers. Potential secondary target species identified in the Plan were
bluegill, brassy jumprock, flat bullhead, smallmouth bass, white sucker, catfish, or carp. Edible-sized
individuals, based on the North Carolina Inland Fishing, Hunting &Trapping Regulations Digest 2021-2022,
or the 2019 NCDWR fish tissue monitoring data were targeted. Ten individual fish from each of the three
targeted species were collected at both the upstream and downstream locations. Each individual fish met
the minimum length requirements. Two duplicate samples were collected from both the upstream and
downstream sample locations. Duplicate samples were collected from different target species.
Attachment C provides a detailed accounting and information regarding fish processing, sample
shipping, and quality control procedures. Attachment C also includes the chain of custody forms,
laboratory analytical reports and field datasheets. TRC and EA performed quality control checks on the
field and analytical data deliverables and a detailed review of the data reports and data summary tables.
Fish tissue samples were shipped to Pace Analytical Services, Green Bay, Wisconsin,for analysis. Two
fish tissue samples were duplicated for laboratory analysis at each location,for a maximum of 64
samples submitted to the laboratory for analysis. The laboratory was responsible for processing fish
fillets, including scaling and filleting. All bass, suckers, and sunfish were processed as skin-on fillets. The
right-side fillet was analyzed in each instance and provided sufficient tissue quantity (2 grams) required
for analysis.

Conclusions
Consistent with requirements outlined in the in NCDEQ approved Plan,fish tissue data were compared
to fish consumption screening levels set by the North Carolina Department of Health and Human
Services (NCDHHS).
NCDHHS developed the following fish tissue screening levels in 2018 using USEPA published regional
screening levels (RSLs) for fish tissue:
■ Arsenic:
— 0.141 mg/kg; noncarcinogenic basis
— 0.00031 mg/kg; carcinogenic basis
■ Cadmium: 0.471 mg/kg; noncarcinogenic basis
■ Zinc: 141 mg/kg; noncarcinogenic basis
Detected concentrations of arsenic, cadmium, and zinc in fish tissue samples collected during the
sampling event were less than the NCDHHS noncarcinogenic fish tissue screening values. A single
detected concentration of arsenic in one upstream notchlip redhorse sample (BR-US-NLR-07) at a
concentration of 0.031 (J) mg/kg is greater than the 0.00031 mg/kg NCDHHS carcinogenic target risk
value for arsenic. The current NCDHHS screening levels are conservatively based on a subsistence
fisherman exposure scenario.
The AZP fish tissue sampling program meets the requirements of the permit and compares favorably to
the NCDHHS screening levels.

Condition Part I,A.(4.)
In accordance with NPDES Permit NC0089109 issued to American Zinc Products(AZP) in Rutherford County,
NC, enclosed is a Revised Fish Tissue Monitoring Plan(Revised Plan)developed for the collection,
preparation and chemical analysis of fish samples collected from the Broad River upstream and downstream
of AZP's permitted discharge outfall. The Revised Plan was edited to address comments provided to AZP by
DWR in a letter dated December 20, 2019, and according to permit condition Part I,A. (4). A responsiveness
summary is included to facilitate the Department's review of the Revised Plan.
The Revised Plan identifies certified labs that may be used for the analytical evaluation of samples that are
collected. A list of potential contractors for field work,including the collection,of fish and sample
preservation is also provided. This information does not representa commitment by AZP to use any of the
listed contractors or laboratories. AZP will select appropriate and qualified service providers to perform
monitoring activities in accordance with the approved monitoring plan.
Following agency approval of the monitoring plan,AZP will follow the revised plan to perform monitoring
within the current permit cycle. Results from monitoring activities will be included with the Company's
application for renewal of the NPDES Permit that is submitted to the Department.
Please advise me if you have any questions. Thank you for your attention to this matter.

Responsiveness Summary AZR Fish Tissue Revised Monitoring Plan and DWR Review Comments(12/20/2019)
• Note addition of CZR Inc. Environmental Consultants Wilmington NC to contractor list.
• Duplicate samples of two duplicates per site for a total of four duplicates
1. Comment: As stated in the permit,fish tissue monitoring of arsenic(As),cadmium(Cd),and zinc (Zn)must be
performed once during the 5-year AZR NPDES permit cycle. For clarity please include these terms in the beginning of
the AZR fish tissue monitoring plan, as well as in the final report.
Response: Page one of the AZR revised Fish Sampling Plan incorporates the exact requirements of the NPDES Fish
Tissue Monitoring requirement and is reproduced in the plan and labeled as Permit Item A. (4.).
2. Comment: Please omit the last two paragraphs on page 2 through page 4(including Figure 1 and Table 1).The referenced
2019. NCDWR fish tissue monitoring activities were conducted via internal agency request,and not specifically intended
to serve as a model for NPDES fish tissue contaminant monitoring of the Broad River. However,it would be reasonableto
list those species collected by DWR in 2019,and to specify which of those species are being targeted for the required
AZR fish tissue monitoring.
Response:The requested deletions have been made as requested. Target species have been identified based on the
DWR suggestions and the 2019 collections.
3. Comment:The plan should outline AZR's proposal to compare arsenic(As),cadmium(Cd),and zinc(Zn) fish fillet
concentrations from two separate locations in the vicinity of the AZR waste water discharge(upstream control, and
downstream). Site boundaries should be separated by a reasonable distance(— I mile)to characterize the potential impact
of AZR's waste water discharge on As,Cd,and Zn concentrations in fish. All of the current NPDES fish tissue monitoring
plans in the state of North Carolina share this paradigm of upstream-downstream comparisons for the purpose of
determining a facility's potential impact on fish contaminant levels.
Response:The AZR revised Fish Sampling Plan incorporates two monitoring locations,one upstream and one
downstream of the AZR facility.
4. Comment: The boundaries of the proposed downstream fish collection reach are reasonable and therefore will be
accepted as is.
Response:No changes necessary related to this comment.
5. Comment: We suggest placement of the upstream sample reach(control)to be above the Jack McKinney Road bridge
(approximately 3 river miles above the AZR waste water discharge),to create considerable distance between the two
reaches and provide similar habitat types and species assemblages for contaminant comparisons.
Response: The AZR revised Fish Sampling Plan incorporates the addition of a Broad River sampling reach from the Jack
McKinney Road Bridge to one mile downstream.
6. Comment:The plan should outline an attempt to collect 10 individuals of 3 targeted species from both sample reaches
(total of 30 fish from each sample reach),with a minimum of 6 individuals per species meeting the permit requirement
(total of 18 fish from each sample reach).
Response: The revised Fish Sampling Plan now targets a goal of 3 species composed of 10 individual fish at each location
with a minimum objective goal of 18 fish from each location.
7. Comment:Based on the NCDWR's 2019 fish collections, the most likely target species in this section of the Broad River
include Largemouth Bass(top predator),Redbreast Sunfish (mid-trophic insectivore),and Notchlip Redhorse(mid-
trophic omnivore). Other suitable species of bass,sunfish,suckers,catfish, or carp should also be retained during
collection efforts.These fish samples may be submitted for analysis if target species are absent or low in numbers,or as
supplemental observations.
Response:The AZR revised Fish Sampling Plan has incorporated the suggested primary target species and the secondary
target species as identified in the DWR comments.
8. Comment: In the final monitoring report,please provide data comparisons to fish consumption screening levels set by the
North Carolina Department of Health and Human Services(NCDHHS)and the Environmental Protection Agency.
Response: AZR is aware that EPA and NCDHHS fish tissue screening levels may be established based on different
assumptions at different times and for different purposes. AZR will reference established standards and criteria and other
such information available at the time the monitoring report is submitted. AZR will submit a final fish monitoring report
with the NPDES permit renewal application as required in our NPDES permit Item A.(4.).

Fish Tissue Sampling Plan American Zinc Recycling NPDES NC0089109

Introduction
This Sampling.Plan is designed to assist with the planning and responses necessary for the
successful compliance of the Fish Tissue Monitoring Condition included in the American Zinc
Recycling (AZR), LLC Forest City,Rutherford County NPDES Permit NC0089109. The Permit
as modified is scheduled with an effective date of June 1, 2019. This Study Plan was revised.
based on NCDWR Comments dated December 20,2019. The NPDES Fish Tissue Monitoring
requirement is included as Permit Item A. (4.) as follows (taken directly from the permit):
A. (4.) FISH TISSUE MONITORING
fG.S. 143-215:.1(b)]
The facility shall conduct fish tissue monitoring once during the permit cycle and submit the
results with the NPDES permit renewal application. The objective of this monitoring is to
evaluate potential uptake of pollutants by fish tissue near the facility's discharge. The
parameters analyzed in fish tissue shall be arsenic, cadmium, and zinc. The monitoring shall
be conducted in accordance with the sampling plan approved by the Division. The plan should
be submitted to the Division within 180 days from the effective date of the permit modification.
Upon approval, the plan becomes an enforceable part of the permit.
Copies of all the study plans, study results, and any other applicable materials should be
submitted.to:

Objectives
All fish tissue sampling performed by American Zinc Recycling(AZR) will be conducted based
on an approved sampling plan (this plan) according to the NPDES permit condition. Any
exceptions to this approved Sampling Plan either due to unforeseen logistical challenges,
difficulty in obtaining target species, safety concerns or other issues will be specifically detailed
in writing and communicated to the NCDWR either during or after field sample collections are
performed.
The purpose of this Sampling Plan is to document sample collection and analytical procedures to
be followed by AZR contractors for the collection and processing of fish samples for analysis of
Arsenic, Cadmium, and Zinc as maybe found in the edible portion(fillet) of target species in the
vicinity of the AZR waste water discharge. After obtaining the appropriate fish samples, fillet
portions will be processed and delivered to a North Carolina certified laboratory for total arsenic,
total cadmium, and total zinc. Results from this sampling and laboratory analysiswill be
reported to the NCDWR with the next AZR NPDES permit renewal application as specified in
the current NPDES permit under:A. (4.)FISH TISSUE MONITORING.
It is the goal of this Sampling Plan to obtain ten individual fish for each of three different target
species at two different locations. One location will be geographically upstream of the AZR
facility and another location will be located geographically downstream of the facility. All fish
submitted for chemical analysis will be representative of edible sizes. This goal, if attainable,
2 ' Page
Fish Tissue Sampling Plan American Zinc Recycling NPDES:NC0089109

will represent a total of 60 individual fish fillet samples for total arsenic, total cadmium, and total
zinc. Sample duplicates will also be submitted for laboratory analysis on four samples.
Sampling Target Species
The resident fish species of the Broad River near the American Zinc Recycling(AZR) facility
are expected to include a number of different fish species based on North Carolina Division of
Water Resources (NCDWR) fish sampling conducted on March 13, 2019. NCDWR Water
Sciences Staff collected fish samples from the Broad River both upstream and downstream of the
AZR facility's discharge. The following eight species were collected for metals analysis by
NCDWR in March of 2019:
Bluegill Sunfish Notchlip Redhorse (Sucker)
Brassy Jumprock(Sucker) Redbreast Sunfish
Flat Bullhead Smallmouth Bass
Largemouth Bass White Sucker
Based on the results of NCDWR fish collection sampling efforts in March 2019, this AZR
Sampling Plan represents a lofty goal. At a minimum, this AZR Sampling Plan will strive for
representation at each location with at least three edible species and a minimum of at least six
individuals from each species selected from the target species list. Thus, a minimum total of 18
fish samples will be selected for laboratory analysis from each location. Because ten individual
representatives of each species may not be attainable at each location, the sampling effort will be
well documented by the selected AZR contractor.
Based on NCDWR's 2019 fish collections and recommendations, the three species chosen as
primary targets for collection in this study include: Largemouth Bass, Redbreast Sunfish, and
Notchlip Redhorse. Each of these three species represent different trophic levels—top predator,
mid-trophic insectivore, and mid trophic omnivore, respectively. If these three primary target
species are absent from each location or a minimum of six individuals from each species are not
attainable then secondary target species may be substituted. Secondary target species may
include: Bluegill Sunfish,Brassy Jumprock, Flat Bullhead, Smallmouth Bass, White Sucker,
catfish, carp or other species.

Broad River Sampling Reach Locations
The Broad River in the vicinity of the AZR facility can be a challenge for many fish collection
approaches including gill nets,hook and line, electrofishing, and other practices. Fish samples
will be obtained from two locations on the Broad River. The Broad River is a rocky, flashy, and
swift waterbody capable of rapid changes in water depth.
The first sampling reach location on the Broad River will start at the Jack McKinney Road
Bridge(approximately three river miles above the AZR facility). The downstream extent of this
sampling reach will be located no further than one mile downstream of the Jack McKinney Road
Bridge.
The second fish sampling reach will obtain fish from the Broad River below the AZP discharge.
The second river sampling reach will start below the AZP discharge in the vicinity of the
Highway 221 bridge over the Broad River(GPS location approximately Latitude 35.20585
Longitude -81.83773). The downstream extent of the sampling reach will be located
approximately one mile downstream of the Highway 221 bridge over the Broad River(GPS
location approximately Latitude 35.205356 Longitude -81.821633).
In any case,depending on the availability of fish, the extent of each actual sampling reach will
be measured and reported using reliable GPS positioning equipment. The agent or contractor
selected for fish sample collections will provide copies of any figures, maps, and photographs
needed to document the location of the sampling reach. Photographs documenting sampling
collection activities will also be provided.
Sampling Technique Methods
It is anticipated that the AZR fish collection contractor will employ boat mounted powered
electrofishing as the primacy means of fish collection. Depending on the selection of a suitable
fish collection contractor, collections may also be accomplished using back pack electrofishing
techniques,hook and line, trot lines,traps, or gilinets. In any case, the collection contractor will
implement measures necessary to ensure that samples are collected and handled properly with
minimal contamination and that each sampling reach is GPS verified. Field sampling efforts will
continue at each location until either the primary or secondary target fish samples have been
collected with a sufficient number of individuals. A minimum of three different species with six
individuals will be collected from each location. Thus, fish collections are expected to result in a
minimum of 36 laboratory samples for individual fish analysis (plus 4 duplicates) for arsenic,
cadmium, and zinc. Regardless of collection method, the successful contractor will have
knowledge,skills, and experience with all sampling techniques used to obtain fish samples. All
personnel involved with electrofishing or other methods employed will be familiar with
operational and safety procedures. At least two fish tissue samples will be duplicated for
laboratory analysis at each location regardless of the total number of individual fish collected at
each location.
If field sampling approaches for fish collections are not successful in obtaining sufficient
individuals(18 per site) for laboratory analysis NCDWR will be consulted to determine
appropriate modifications.

Analytical Requirements—
Fish Tissue Samples will be analyzed by a North Carolina Laboratory certified by the Division
of Water Resources. All fish tissue samples will be analyzed for total arsenic, cadmium, and
zinc. Laboratory analytical capabilities will be evaluated and compared to the DWR PQL
reporting limits for arsenic, cadmium, and zinc prior to contractor selection. At least two fish
tissue samples will be duplicated for laboratory analysis at each location regardless of the total
number of individual fish collected at each location.
Sample Handling and Delivery/Shipment
Fish tissue samples collected for analyses must be processed and delivered/shipped to the
selected certified laboratory in order to prevent decomposition or contamination. In all activities
the selected contractor will avoid potential sources of arsenic, cadmium, and zinc contamination
—i.e. no use of galvanized buckets,no cigarette smoking, powderless nitrile gloves will be worn
in all fish handling activities. Fish will be removed from plastic live wells, holding tanks, or
buckets, and rinsed with ambient water to remove foreign matter, and placed on a clean or new
protective surface (i.e. aluminum foil) for sorting,weighing, length measurements, and
wrapping. All samples will be processed individually. No fish will be composited into
composite samples.
• An individual whole fish wet weight will be determined for each fish to the nearest gram
and recorded on Field Data. Sheet#2. All individual samples will be weighed on
scales/balances that are properly calibrated and of adequate accuracy and precision to
weigh samples to the nearest gram. Scales and or balances will be checked for calibration
at the beginning of each weighing session.
• A total length will be determined for each fish to the nearest centimeter using a length
board such as the Wildco® Model 118 and recorded on Field Data Sheet#2). Individual
fish will be identified to species under the supervision of an experienced staff familiar
with North Carolina fish. Fish will be identified using current, identification manuals and
other appropriate taxonomic literature (i.e.: Menhinick, E. F. 1991).
• Skins on fish selected for analysis will be examined for breaks or lacerations from
sampling gear as a possible source of contamination. Fish samples will be identified by
species and sorted by species before any packaging or processing for delivery/shipment
to the certified laboratory.
• Fish selected for metals �
analysis will be weighed and measured for length. Fish will be
individually wrapped and labeled with sample number, species name, weight, and length
in appropriate arsenic, cadmium, and zinc free wrap (i.e. new aluminum foil) and placed
by species in polyethylene bags. After removing as much air as possible, the bags will be
closed and tagged with the date, time, station name, species, and collector(s).
• All fish (in bags)will be placed on wet ice and chilled to 4 degrees C for transport to
either the certified laboratory or other suitable tissue processing location for preparation
of fillet samples within 48 hours.
• All fish will be processed as fillet samples. No fish samples for whole body metals
analysis will be sent to the certified laboratory for whole body metals analysis.
• All bass and sunfish species will be processed as fish fillet samples with skin-on intact.
• All Suckers, Catfish, and Bullheads, and Carp will be processed as fillet samples with
skin-off(no skin included).

Fish Tissue Sample Processing Procedures
• Individual fish selected for filleting will be unwrapped and inspected carefully to ensure that
they have not been compromised in any way(i.e., not properly preserved during shipment).
Any specimen deemed unsuitable for further processing and analysis should be discarded and
identified on the sample processing record.
• Equipment used in processing fish samples for metals analysis will be free from arsenic,
cadmium, and zinc contamination. As such, glass and plastic use will be prioritized. Only
when necessary(i.e. knives) stainless steel will be used. Prior to preparing fish samples, all
hard surfaces used in the processing will be washed with a detergent and rinsed with verified
metal free water(treated by reverse osmosis—R.O.). Any necessary utensils and containers
will be thoroughly cleaned and rinsed with tap water, soaked in 50 percent HNO3 (at least
reagent grade)for 12 to 24 hours, and then rinsed with metal-free water.
• All processing will be performed on surfaces covered with heavy duty aluminum foil.
Aluminum foil will be rinsed with R.O. water between fish or new foil will be used. Filleting
will be performed using talc free disposable gloves. Gloves will be rinsed between samples to
prevent cross contamination. Fillets will be resected using high grade stainless steel knives.
Knives are rinsed with R.O. water between fish species from the same station.
• Fillets will be removed from the lateral area of the fish behind the head and pectoral fin and
will include the belly flap. Extreme care will be taken not to cut into the gut cavity as it may
contaminate the fillet tissue.
• Filleting will be done on cutting boards covered with heavy duty aluminum foil that is
changed after each filleting. Fillet tissues will be removed from whole fish with clean,high
quality, corrosion-resistant stainless steel or with titanium blade knives and polypropylene
handles.
• Skin-on fillets will be processed by removing scales from the intact fish. Fish will be scaled
prior to filleting using an automatic rotary scaler or hand scaler. Fish will then be rinsed with
R.O. water to remove slime and foreign matter. Any scaling instruments will also be rinsed
between fish to prevent contamination. The scale free fish fillet will be finely minced using
the same knives to prepare individual fillet homogenates to ensure equal distribution of
contaminants throughout the sample. These individual fillet tissue homogenates will be
stored in heavy duty aluminum foil and appropriately labeled for delivery to the certified
laboratory for chemical analysis. Where possible the final individual homogenized sample
should be composed of approximately 100 g of tissue to ensure an adequate amount of
material for analysis. Since samples will be composed of individual fish fillets it may not be
possible to achieve 100g of sample in every case.
• Fish fillet for skin-off analysis will be separated from the skin using knives. Fish will be
skinned prior to filleting for all catfish and bullheads. Sucker and Carp fillets will be
separated from the fish body and subsequently separated from the skin using knives. The skin
free fish fillet will be finely minced using the same knives to prepare individual fillet
homogenates to ensure equal distribution of contaminants throughout the sample. These
individual fillet tissue homogenates will be stored in heavy duty aluminum foil and
appropriately labeled for delivery to the certified laboratory for chemical analysis. Where
possible the final individual homogenized sample should be composed of approximately 100
g of tissue to ensure an adequate amount of material for analysis.

A. (2.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 0.9%.
The permit holder shall perform at a minimum, quarterlrq monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be
performed during the months of January, April, July and October. These months signify the
first month of each three-month toxicity testing quarter assigned to the facility. Effluent
sampling for this testing must be obtained during representative effluent discharge and shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or
ChV below the permit limit, then multiple-concentration testing shall be performed at a
minimum, in each of the two following months as described in "North.Carolina Phase II
Chronic Whole Effluent Toxicity Test Procedure" (Revised-December 2010) or subsequent
versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,
DWR Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center

based on the toxicity testing quarter, which is the three month time interval that begins on the
first day of the month in which toxicity testing is required by this permit and continues until the
final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Resources indicate potential impacts to the receiving stream, this permit may be
re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival, minimum control organism reproduction, and appropriate
environmental controls, shall constitute an invalid test and will require immediate follow-up
testing to be completed no later than the last day of the month following the month of the initial
monitoring.
A. (3.)ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of
this permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
a Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (all
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted facilities
to enter monitoring data and submit DMRs electronically using the internet. Until such time
that the state's eDMR application is compliant with EPA's Cross-Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to
the state electronically using eDMR and will be required to complete the eDMR submission by
printing, signing, and submitting one signed original and a copy of the computer printed
eDMR to the following address:
NC DEQ / Division of Water Resources / Water. Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be

Starting on December 21, 2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment.Program Annual Reports; and.
• Clean.Water Act(CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request
a Waiver from Electronic Reporting' section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the
time of each electronic submission. The permittee should use the EPA's website resources to
identify the initial recipient for the electronic submission.

1. INTRODUCTION
The American Zinc Products (AZP),LLC was required to develop a sampling plan to maintain
compliance with the requirements issued in National Pollutant Discharge Elimination System
(NPDES)permit#NC0089109. The plan was submitted to the North Carolina Division of Water
Resources (NCDWR) Water Quality Permitting Section and Water Sciences Section for review
and comment. Comments were addressed in December 2019 and a final version of the sampling
plan was submitted in April 2020. The primary component of the sampling plan required a fish
collection for evaluation of target metal concentrations present within the fish tissue. EA
Engineering, Science, and Technology, Inc.,PBC (EA) will be performing fish tissue collection
and facilitation services to meet the tissue collection and analysis requirements.
1.1 NPDES PERMIT REQUIREMENTS
In accordance with NPDES permit#NC0089109, the following Fish Tissue Monitoring
Condition requirement was stipulated therein:
A. (4)FISH TISSUE MONITORING
[G. S. 143-215. 1(b)j
The facility shall conduct fish tissue monitoring once during the permit cycle and submit the
results with the NPDES permit renewal application. The objective of this monitoring is to
evaluate potential uptake of pollutants by fish tissue near the facility's discharge. The
parameters analyzed in fish tissue shall be arsenic, cadmium, and zinc. The monitoring shall
be conducted in accordance with the sampling plan approved by the Division. The plan should
be submitted to the Division within 180 days from the effective date of the permit modification.
AZP provided an updated revised fish tissue monitoring plan to the NCDWR NPDES Water
Quality Permitting Section in April 2020 (AZP 2020). EA has reviewed the AZP Sampling Plan
and integrated it into this SOP.
1.2 OBJECTIVE
The primary objective is to fulfill the NPDES #NC0089109 Fish Tissue Monitoring Condition
requirement, which consists of collecting fish tissue samples upstream and downstream of the
AZP discharge in the Broad River to be analyzed for arsenic (As), cadmium(Cd), and zinc (Zn).

2. METHODS AND MATERIALS
The sampling locations, sampling schedule, collection methods, target species, sample
processing procedures, and shipping details are described below. Sampling will be performed at
two locations near the AZP facility within Broad River during Spring of 2022 with a target of
mid-May. Three species of edible-size fish representing three different trophic levels will be
targeted for tissue collection. The primary sampling gear will be boat electrofishing, which may
be augmented by hook-and-line, gill nets, hoop nets, and trap nets.
2.1 SAMPLING LOCATIONS
Fish samples will be obtained from two locations on the Broad River, one upstream(Figure 1)
and the other downstream of the AZP facility(Figure 2). The upstream location will extend from
the Jack McKinney Road Bridge to approximately one mile downstream of the bridge (Figure 1):

2.2 SAMPLING SCHEDULE
Based on monthly mean river stage and flow data(USGS 02151500 Broad River near Boiling
Springs,NC; Table 1) and river discharge data from 2021 (Figure 3), it was determined that
sampling would be conducted no earlier than approximately mid-May to minimize river levels
that would be unsafe and/or too turbid for sampling. The proposed sampling scheduled is
provided in Table 2.

(a)Daily email updates will be provided to TRC and AZP regarding numbers of target species and any issues
encountered.
(b)This could be delayed by inclement weather or additional days of sampling if requested by AZP.
EA will track river stage and discharge conditions via the Broad River USGS gaging station
prior to sampling, as well as predicted conditions via the Advanced Hydrologic Prediction
Service. In addition, EA will also contact Mr. Charles Howell (AZP Environmental Manager)to
gauge water clarity via turbidity readings. Turbid conditions can mask boating hazards (e.g.,rock
outcrops, deadfalls, shallow riffle/run areas), and make electrofishing inefficient in terms of the
ability to observe stunned fish.

EA Engineering, Science,and Technology,Inc.,PBC May 2022
2.3 COLLECTION METHODS
EA's primary collection method will consist of DC-pulsed electrofishing equipment that will
either be boat-mounted(16-ft jon boat with 9.9 hp outboard) or wadeable. However, gill nets,
trap nets, hoop nets, and limb/trot lines may also be deployed overnight at each location. The
sampling effort is estimated to encompass eight days, which will consist of four days of
electrofishing and potentially two overnight sets of gill nets, trap nets, hoop nets, and/or limb/trot
lines at each location. EA has obtained a Scientific Fish Collection License from the North
Carolina Wildlife Resources Commission(NCWRC) that specifies the designated species,
numbers of specimens, collection methods, and sampling locations (Appendix A). EA personnel
assigned to this project have the knowledge, skills, and experience with all sampling techniques
proposed to obtain the fish samples. In addition, all personnel involved with electrofishing or
other methods employed are familiar with operational and safety procedures.
2.4 TARGET FISH SPECIES
The three target species are Largemouth Bass, Redbreast Sunfish, and Notchlip Redhorse. They
each represent different trophic levels—top predator, mid-trophic insectivore, and mid-trophic
omnivore, respectively. If these three primary target species are absent from each location or a
minimum of six appropriately-sized individuals from each species are not attainable, then
secondary target species will be substituted: Bluegill, Brassy Jumprock, Flat Bullhead,
Smallmouth Bass, White Sucker, catfish, carp, or other species. Edible-sized individuals,based
on the North Carolina Inland Fishing, Hunting& Trapping Regulations Digest 2021-2022, or
the 2019 NCDWR fish tissue monitoring data (NCDWR 2019), will be retained for each game
fish species; however, minimum lengths for nongame species will be those reported by the
NCDWR(2019) fish tissue monitoring data:
Table 3.Minimum Lengths for Target Fish Species
Species Minimum Length Inches Minimum Length Inches
(Regulations Digest) (2019 NCDWR)
Largemouth Bass 14 (allows 2 fish<14 [356 mm]) 8.5 (215 mm)
Redbreast Sunfish none 5.0 (128 mm)
Notchlip Redhorse none 10.8 (275 mm)
Bluegill none 5.4 (138 mm)
Brassy Jumprock none 12.7 (323 mm)
Flat Bullhead none 6.7 (171 mm)
Smallmouth Bass 14 (allows 2 fish<14 [356 mm]) 8.5 (216 mm)
White Sucker none 11.7 (1 fish; 297 mm)
Golden Redhorse none 14.3 (364 mm)
The goal is to obtain six to 10 individual fish for each of the three different target species at the
two sampling locations. Therefore, 18 to 30 individuals will be selected for laboratory analysis
from each location. If field sampling is not successful in obtaining sufficient individuals (18 per
location), the NCDWR will be consulted by TRC Companies, Inc. (TRC)/AZP personnel to
determine appropriate modifications. Because sufficient individuals of each species may not be
attainable at each location, the sampling effort will be well documented by EA. To that end,

EA Engineering,Science,and Technology,Inc.,PBC May 2022
Field Data Sheet# 1 and Field Data Sheet# 2 (Appendix B) from the Sampling Plan will be
used to document the fish tissue collection results. One set of data sheets (2 pages)will be
completed for each location for each day sampling is conducted. In addition, the extent of each
actual sampling reach will be measured and reported using GPS positioning equipment. EA will
provide a map and photographs to document the sampling activities within both locations.
2.5 FIELD SAMPLE PROCESSING
Fish tissue samples collected for analyses will be processed and delivered/shipped to Pace
Analytical Services (Pace) in a manner to prevent decomposition or contamination. During all
activities, EA will avoid potential sources of arsenic, cadmium, and zinc contamination (e.g., no
use of galvanized buckets,no cigarette smoking, powderless nitrile gloves will be worn during
all fish handling activities). Fish will be removed from plastic live wells,holding tanks, or
buckets, rinsed with ambient water to remove foreign matter, and placed on a clean or new
protective surface (i.e.,plastic wrap) for sorting, weighing, length measurements, and wrapping.
All samples will be processed individually as noted below:
• An individual whole fish wet weight will be determined for each fish to the nearest gram
and recorded on Field Data Sheet#2 (Appendix B). All individual samples will be
weighed on scales/balances that are properly calibrated and of adequate accuracy and
precision to weigh samples to the nearest gram.
• Total length will be determined for each fish to the nearest millimeter using a calibrated
measuring board and recorded on Field Data Sheet#2 (Appendix B). Individual fish will
be identified to species by experienced staff using current identification manuals and other
appropriate taxonomic literature (e.g., Boschung and Mayden 2004; Jenkins and Burkhead
1993; Marcy et al 2005; Menhinick 1991; Page and Burr 2011).
• Fish with lesions or lacerations will not be kept for analysis.
• Each fish will be placed in a clean plastic bag that will be externally labeled with the
sample number, species name, weight, and length (Appendix C). The self-adhesive label
will be additionally secured to the bag by clear packing tape. The labeled bag will be
placed in a second clean plastic bag to protect the label. The sample information will then
be documented on a chain-of-custody Form (Appendix D).
2.5.1 Label Format
External labels will include a sample identification code that will be unique to each specimen:
SITE—SPP-##-DDMMMYY-CONT: where, SITE =Location Code, SPP= Species Code, ##
=chronological specimen number for this species, DDMMMYY=day,month, and year, and
CONT =Contract Code (NPDES).

2.5.2 Chain-of-Custody
EA will complete a chain-of-custody provided by Pace (Appendix D)that will be included with
the fis
h tissue samples when sent to the analytical laboratory. The chain-of-custody will include
the unique sample number, date, and time of collection, and the name and signature of the field
collector. The analytical laboratory will counter-sign and provide copies to EA with the
analytical report.
2.5.3 Sample Shipment and Delivery
Whole fish samples will be double-bagged and frozen in an on-site chest freezer during the
sampling effort. Upon sample effort completion, fish will be placed on wet ice and chilled to
4°C in insulated and water-tight coolers. Coolers will be lined with trash bags to contain ice
melt and cushioned with absorbent pads and bubble wrap as needed. Packed coolers will be
sealed with packaging tape to ensure proper closure of cooler lid and cooler plug (if present).
A completed chain-of-custody(Appendix D) will be placed in a Ziploc®bag and taped to the
lid of the cooler. Coolers will be shipped for next day delivery to Pace via FedEx or UPS.
2.6 DELIVERABLES
EA will provide TRC the field datasheets, GPS waypoints, maps,photographs, additional field
notes (those not included on the field datasheets), and the analytical report from the laboratory.
EA will also develop summary tables describing number and type of species collected at each
sampling location and designation of fish that were sent to the laboratory for analysis. All
information will be reviewed by appropriate personnel prior to submittal.

3. LABORATORY PROCESSING AND ANALYSIS
Fish tissue samples will be analyzed by Pace, which maintains accreditation in North Carolina. It
should be noted that based on a review of applicable fields of accreditation, NCDWR does not
certify for tissue analysis. All fish tissue samples will be analyzed for total arsenic, cadmium,
and zinc. Laboratory analytical capabilities have been evaluated and compared to the NCDWR
Practical Quantitation Limit(PQL)reporting limits for arsenic, cadmium, and zinc (Appendix
E). Two fish tissue samples will be duplicated for laboratory analysis at each location regardless
of the total number of individual fish collected at each location. Therefore, a maximum of 64
samples will be analyzed by the laboratory. The laboratory will be responsible for filleting. Their
Laboratory Standard Operating Procedures (SOPs) for relevant analytical methods and the
Laboratory Quality Manual have been included in Appendix F. All bass and sunfish species will
be processed as skin-on fillets. Pursuant to our discussion on 13 December 2021, all suckers and
carp will also be processed as skin-on fillets. In contrast, all catfish and bullheads will be
processed as skin-off(no skin included) fillets. Also based on that discussion, only the right fillet
will be analyzed for all samples with the left fillet saved for potential future analysis. However,
for those instances where the right fillet does not provide sufficient mass for analysis, then both
fillets will be combined and analyzed. The minimum mass per sample for Pace is 2g.

4. QUALITY CONTROL
This SOP manual provides EA's staff with guidance regarding sampling methodologies, the
equipment required, and specifications regarding acceptable calibration intervals and procedures
for various field gear (e.g., scales/balances), communication, quality control and assurance
measures, as well as health and safety information. It also establishes various other protocols to
be followed through this project.
In accordance with EA's Corporate Quality Management Plan (the master document for all
disciplines at EA), we use SOPs to efficiently promote quality through consistency. This SOP is
a project-specific document that integrates the methodologies and guidance with detailed
specifications. It ensures that the AZP NPDES Permit objectives will be met and that the
integrity of EA will be maintained. It also allows each staff member to understand his or her
duties and responsibilities, as well as providing a means for minimizing disruptions associated
with staff turnover.
4.1 EQUIPMENT CALIBRATION
4.1.1 Measuring Boards
Measuring boards and rulers used to determine lengths of fish are calibrated once after purchase,
manufacture, or repair. The measuring board is calibrated with a ruler or tape that is certified by
the manufacturer to be traceable to the National Bureau of Standards (NBS). Ten randomly
selected points between 20 and 600 mm are visually checked against the standard ruler. Only
those measuring boards that are within the stated accuracy of the standard ruler(±1.5 mm) are
used. Measuring boards that are outside the accuracy of the standard ruler are discarded. The
results of the calibration are entered on a Calibration Record Form.
4.1.2 Measuring Scales
Spring scales are calibrated semi-annually by weighing 3-5 weights that are within the
appropriate weight range. All weights are class T or better, and are certified by the manufacturer
to be traceable to the NBS. The readings are compared to the known weight and the results are
recorded on a Calibration Record Form. Scales having less than 10 percent error are retained in
service whereas those that exceed 10 percent error are adjusted and recalibrated, or removed
from service and destroyed.
4.2 FIELD WORK
Each field crew member will be expected to have read and have on hand at all times a copy of
the SOP. A master field equipment checklist has been prepared so that the field crew has all the
appropriate equipment needed for sampling (Appendix G). All specifications detailed
previously will be carefully followed. Additional care will be taken to sample at the locations
specifically needed to meet NPDES requirements; GPS coordinates are provided in AZP (2020)
and Section 2.1 (see Figure 2) of the SOP. Two experienced(10 years or more) EA biologists
Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection

Version:FINAL
Page 12
EA Engineering, Science,and Technology,Inc.,PBC May 2022
will conduct the field collections, which will ensure strict adherence to the SOP,proper
identification of fish captured,and sound judgment regarding collection procedures and during
potentially hazardous conditions. The sampling crew will be required to have our current
NCWRC Scientific Fish Collection License on hand when in the field (Appendix A).
4.3 FIELD AND LABORATORY DATA
EA will compare all (i.e., 100%) hand-entered field data against the hard copy field or
laboratory data sheets. These comparisons will be kept as part of the project file, documented on
a data processing log sheet, and be made available to the client at their request. In addition, the
comparisons will be done by an experienced fisheries biologist; data will not be checked by a
non-biologist. EA routinely provides this type of QC for all its projects.
EA will review and perform quality control checks on the analytical data provided by Pace. After
the data are received, EA will perform a data assessment screening on the laboratory's analytical
data packages and electronic data deliverables (EDDs). Data will be reviewed for completeness
by comparing them to the chain-of custody. Review of data usability will be accomplished by
comparing the contents of the analytical data packages and quality assurance/quality control
(QA/QC) results to the requirements contained in the Quality Assurance Project Plan or Work
Plan, the respective methods, and the laboratory SOPs. EA will resolve any discrepancies with
the laboratory and will inform AZP of any issues or delays.

5. HEALTH AND SAFETY
Due to limited boating access of the study area, the use of electrofishing equipment, and
maneuvering across forested and developed regions, personnel may potentially be exposed to a
variety of hazards. Since crew safety is of the utmost importance,no personnel will be required
or instructed to work in surroundings or under conditions that are unsafe or dangerous to his or
her health and each individual employee will be responsible for complying with applicable safety
requirements, wearing prescribed safety equipment, and preventing avoidable accidents.
5.1 BOATING AND ELECTROFISHING
EA's Corporate Vessel and Operations Manual and Small Boat Operations SOP (Appendix H)
provides the basic policies and procedures regarding safety and health during the performance of
work involving boating and watercraft activities, which are to be followed during this study.
Prior to sampling, the EA field crew will notify on-site AZP and TRC staff of EA's planned
sampling route for the day. At a minimum, all boats will be equipped with required Coast Guard
safety equipment(e.g., approved personal floatation devices, fire extinguisher, signal flares,
horn, etc.) and a first aid kit. EA staff on board the boat will also have cell phones available to
contact on-site AZP and TRC staff or emergency services in the event of an emergency. A GPS
will be on board to provide emergency personnel with GPS location information if needed.
EA's Electrofishing Field Manual (Appendix H)provides details on basic concepts and safety
issues involving electrofishing systems, including safe equipment operations and appropriate
personal protective equipment (PPE) during active sampling.
Watercraft and Trailer Registrations are provided in Appendix I.
5.2 WEATHER HAZARDS
Weather conditions will be taken into consideration during each sampling effort. Heavy rains,
electrical storms, high winds, and extreme temperatures, for example, may create extremely
dangerous situations for employees. Inclement weather may also impair equipment performance.
Whenever unfavorable conditions arise, the Crew Leader will evaluate both the safety hazards
and ability of the employees to effectively perform given tasks under such conditions. Work on
the sampling vessel will be suspended during thunderstorms, tornadoes, hurricanes, or other
severe weather events. Weather conditions will be monitored via broadcast from marine radio
channel to identify the approach of severe weather situations.
5.3 HEAT STRESS
Prolonged exposure to heat can result in heat rash (prickly heat),heat cramps, heat exhaustion, or
heat stroke. Heat stroke is life threatening and requires immediate professional medical attention.
An overview of these heat-induced illnesses and proper preventative actions are described below.
Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection

Version:FINAL
Page 14
EA Engineering, Science,and Technology,Inc.,PBC May 2022
5.3.1 Heat Rash (Prickly Heat)
Heat rash, which is commonly observed in tropical climates, is a painful temporary condition
caused by clogged sweat pores, typically from sleeping in hot, humid quarters. Heat rash appears
as tiny red bumps on the skin and can impair sweating, resulting in diminished heat tolerance.
Heat rash can usually be cured by providing cool sleeping quarters;body powder may also help
absorb moisture.
5.3.2 Heat Cramps
Heat cramps are characterized by painful intermittent spasms of the voluntary muscles following
hard physical work in a hot environment. Heat cramps usually occur after heavy sweating and
often begin towards the end of the workday. The cramps are caused by a loss of electrolytes,
principally salt. This results in fluids leaving the blood and collecting in muscle tissue, resulting
in painful spasms. Treatment consists of increased ingestion of commercially available
electrolytic"sports" drinks (because of individual sensitivity, it is best to dilute by doubling the
amount of water required by package directions or add water to the liquid form).
5.3.3 Heat Exhaustion
This condition is characterized by profuse sweating, weakness, low blood pressure, rapid pulse,
dizziness, and frequently nausea and/or headache. The skin is cool and clammy and appears pale.
The body core temperature is normal or depressed. Victim may faint and/or vomit. This is the
most common work-related heat illness, and usually occurs after an extended period of work—
look for signs of onset after lunch—an employee may suddenly need to sit down, feel faint,
weak,or nauseated.
First aid consists of placing the victim in a cool area, loosening clothing,placing in a head-low
(shock prevention)position, and providing rest and plenty of fluids. Any worker who is a victim
of heat exhaustion may not be exposed to a hot working environment for an absolute minimum
of 24 hours, and if fainting has occurred, the victim should not return to any work until
authorized by a physician.
5.3.4 Heat Stroke
This is the most serious heat disorder, is life threatening, and is a true medical emergency. It
results when the body's heat dissipating system is overwhelmed and shuts down
(thermoregulatory failure). Heat stroke results in a continual rise in the victim's deep core body
temperature, which is fatal if not checked. The symptoms are hot, dry, flushed skin, elevated
body core temperature, convulsions, delirium, unconsciousness, and possibly death.
First aid consists of immediately moving victim to a cool area; cool the body rapidly by
immersion in cool (not cold) water or sponging the body with cool water; treat for shock and
obtain immediate medical assistance. Treatment response time is critical when assisting a victim
of heat stroke! Do not give coffee, tea, or alcoholic beverages.

EA Engineering,Science,and Technology,Inc.,PBC May 2022
5.3.5 Preventative Measures
Unfortunately, there are no known PPE to prevent heat-related illnesses. However,some
preventative measures to avoid heat stress include:
• Frequent resting in cool or shaded areas,
• Consumption of large quantities of potable water or diluted electrolyte beverages,
following the suggested hydration target in Table 5:
Table 5.Hydration Targets based on Air Temperature and Time Periods between Breaks
Temperature Work Level Maximum Minutes Worked Hydration Target
Between Hydration Breaks
<80°F Normal -- 8-12 oz./hr.
80-85°F Normal -- 8-16 oz./hr.
86-90°F Normal 50 12-20 oz./hr.
91-95°F Normal 45 16-24 oz./hr.
>96°F Normal 40 24-32 oz./hr.
• Following a work/rest regiment from Table 6:
Table 6. Work/Rest Schedule based on Air Temperature
Ambient Temperature Work(hours) Rest(minutes)
70°F 3 15
75°F 2'/2 15
80°F 2 15
85°F 1'/2 15
90°F 1 15
Other factors, such as a worker's acclimatization, level of physical fitness, and age, may increase
or decrease his/her susceptibility to heat stress. Before assigning a task to an individual worker,
these factors will be taken into account to ensure that the task will not endanger the worker's
health.
If a heat-related illness is suspected or observed, the affected person must be moved to a cool or
shaded area and given plenty of liquids to consume. If symptoms of a heat stroke are observed,
the victim will be cooled immediately and treated as a medical emergency. Liquids will be
readily available to ensure that workers stay hydrated.
5.4 BIOLOGICAL HAZARDS—INSECT BITES/STINGS
Protective outer clothing such as gloves,hard hats, and coveralls can reduce the potential for
insect bites and stings. Insect bite symptoms may include redness, rash, swelling, chills, fever,
diarrhea, and vomiting. Any worker who has been bitten or stung and shows symptoms of a
severe reaction should seek medical assistance immediately. Workers who know of their
allergies to insects should advise their supervisor prior to field activities and should carry an
antidote kit, if necessary.
Broad River,Rutherford County,North Carolina SOP-NPDES Fish Tissue Collection

Version:FINAL
Page 16
EA Engineering, Science,and Technology,Inc.,PBC May 2022
When working in areas near heavy vegetation (possibly the riverbank) and to prevent contact
with disease-carrying ticks, workers should wear long-sleeved shirts, long pants, and boots that
extend above the ankle with socks pulled over pant cuffs or with pants legs taped to boots.
Insect repellant is also an effective means of tick control. Workers should check clothing, skin,
and hair for the presence of ticks periodically and thoroughly at the end of each workday. If a
tick attaches to the body, it should be removed by gently tugging with tweezers where the mouth
enters the skin. The tick should not be killed prior to removal.
5.5 BIOLOGICAL HAZARDS —SNAKES
There are six species of venomous snakes present in North Carolina and care must be taken to
avoid encounters and potential bites. Staff will be aware of physical appearances of venomous
snakes but will take care to avoid all snakes. When walking through wooded areas, check the
location of your next step prior to moving forward to ensure it is clear of snakes. Wear closed-
toed shoes and long pants to reduce the likelihood of a snake bite if a venomous snake is
disturbed.
5.6 BIOLOGICAL HAZARDS—FISH
Care must be taken and the proper PPE used when handling certain fish species to avoid getting
cut, spined, or bitten. Proper handling of fish will be performed by experienced EA staff to
reduce the likelihood if injury. Any worker that gets injured from a fish should seek medical
attention immediately.
5.7 POISON IVY AND RELATED PLANTS
Poison ivy,poison oak, and poison sumac have poisonous sap (urushiol) in their roots, stems,
leaves, and fruits. The urushiol may be deposited on the skin by direct contact with the plant or
by contact with contaminated objects, such as clothing, shoes, tools, and animals. Preventative
measures include: wear long-sleeved shirts and long pants tucked into boots; wear cloth or
leather gloves; apply barrier creams (e.g., Ivy Block) to exposed skin; and be able to identify
poison ivy, oak, and sumac plants. If you are exposed, according to the U.S. Food and Drug
Administration (FDA), you should quickly (within 10 minutes): 1) cleanse exposed areas with
rubbing alcohol; 2) wash the exposed areas with water only (no soap yet, since soap can move
the urushiol, which is the oil from the poison ivy that triggers the rash, around your body and
actually make the reaction worse); 3) take a shower with soap and warm water; and 4)put gloves
on and wipe everything you had with you, including shoes, tools, and your clothes, with rubbing
alcohol and water.
Unfortunately, if you wait more than 10 minutes, the urushiol will likely stay on your skin and
trigger the poison ivy rash. You may not be able to stop it on your skin, but you might still scrub
your nails and wipe off your shoes, etc., so that you do not spread the urushiol to new areas.

5.8 ALLERGIC REACTIONS
When in the field, personnel may be exposed to allergens that can cause mild to severe allergic
reactions. The following guidelines will explain how to help a person having an allergic reaction.
For a mild to moderate reaction:
• Calm and reassure the person having the reaction, as anxiety can worsen symptoms.
• Try to identify the allergen and have the person avoid further contact with it. If the
allergic reaction is from a bee sting, scrape the stinger off the skin with something firm
(such as a fingernail or plastic credit card). Do not use tweezers; squeezing the stinger
will release more venom.
• If the person develops an itchy rash, apply calamine lotion and cool compresses.
Avoid medicated lotions.
• Watch the person for signs of increasing distress.
• Get medical help. For a mild reaction, a physician may recommend over-the-
counter medications (such as antihistamines).
For a severe allergic reaction:
• Check the person's airway, breathing, and circulation(the ABCs of Basic Life
Support). A warning sign for dangerous throat swelling is a very hoarse, whispered
voice or coarse sounds when the person is breathing air in. If the victim is having
difficulty breathing,is very weak, or is losing consciousness, call for emergency
medical assistance.
• Calm and reassure the person.
• If the person has emergency allergy medication on hand, help the person take or
inject the medication. Avoid oral medication if the person is having difficulty
breathing.
• Take steps to prevent shock. Have the person lie flat, elevate the person's feet about
12- inches, and cover him or her with a coat or blanket. DO NOT place the person
in this position if a head,neck,back, or leg injury is suspected or if it causes
discomfort.

5.9 EMERGENCY RESPONSE PLAN
In the event of an emergency, the information available at the time must be properly evaluated
and the appropriate steps taken to implement the emergency response plan. The Crew Leader or
senior onsite supervisor will assume command of the situation and call 911 from the nearest
telephone or cell phone, notify authorities of your location(the docking point at which you will
meet them), evacuate personnel as needed, and take other steps needed to gain control of the
emergency.
Appropriate first aid will be given and emergency contacts will be made. Emergency situations
will be handled by offsite support personnel; however, initial response and first aid will be
available from qualified onsite personnel. Once the situation is under control, the Crew Leader
or designee will immediately call EA's Corporate Safety and Health Officer(Rob Marcase at
410-329-5192)and must complete an Accident/Loss Report(Appendix J).
The nearest hospital to the project site is Spartanburg Regional Hospital, located at 101 East
Wood Street in Spartanburg,South Carolina(864-560-6000).Driving directions from the study
area are provided in Appendix J.
5.10 CORONAVIRUS DISEASE 2019 (COVID-19)
All EA staff will be fully vaccinated against COVID-19 prior to arrival on-site. EA staff
will adhere to current state and/or local PPE and social distancing requirements, as
necessary. Appropriate PPE, including face masks and hand sanitizer, will be available to
EA staff as needed.

LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
1.0 PURPOSE AND SCOPE
1.1 Purpose
This quality manual (manual) outlines the quality management system (QMS) and management
structure of the laboratories and service centers affiliated with the environmental sciences (ENV)
division of Pace Analytical Services, LLC (PAS). A laboratory is defined by ENV as any facility,
however named, that provides testing, sampling, or field measurement services. When the term
`laboratory" is used in this manual, the term refers to all locations listed on the Tide Page of this
manual and in Section 4.1.3 unless otherwise specified.
The ENV quality management system is also referred to as the quality program throughout this
document. In this context, the phrase "quality management system" and "quality program" are
synonymous and may be referred to by the acronym QMS.
The quality management system is the collection of policies and processes established by ENV
management to consistently meet customer requirements and expectations, and to achieve the goals
of providing PAS customers with high quality, cost-effective,analytical measurements and services.
The quality management system is also intended to establish conformance1 and compliance with the
current versions of the following international and national quality system standards:
■ ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories
• NELAC/TNI Standard Volume 1:Management and Technical Requirements for Laboratories Performing
Environmental Analysis
'The statement of conformity to these Standards pertains only to testing and sampling activities carried out by the laboratory
at its physical address,in temporary or mobile facilities,in-network,or by laboratory personnel at a customer's facility.
In addition to the international and national standards,the quality management system is designed to
achieve regulatory compliance with the various federal and state programs for which the laboratory
provides compliance testing and/or holds certification or accreditation. When federal or state
requirements do not apply to all ENV locations, the requirements for compliance to those
specifications are provided in addendum to this manual or in other documents that supplement the
manual. Customer-specific project and program requirements are not included in the manual in order
to maintain client confidentiality.
• A list of accreditation and certifications held by each laboratory associated with this manual is
provided in Appendix A.
• A list of analytical testing capabilities offered by each laboratory associated with this manual is
provided in Appendix B.
1.2 Scope and Application
This manual applies to each of the PAS locations listed on the Tide Page.
The manual was prepared from the quality manual template (template) created by ENV corporate
quality personnel. The template outlines the minimum requirements ENV management considers
necessary for every ENV location,regardless of scope of services or number of personnel,to establish
in order to maintain a quality management system that achieves the objectives of the Quality Policy
(See 4.2.2). In this regard, the template is the mechanism used by the corporate officers (a.k.a. 'top
Page 7 of 100

°ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC

management') to communicate their expectations and commitment for the quality program to ENV
personnel.
Each location also has the responsibility to comply with federal and state regulatory and program
requirements for which it provides analytical services and holds certification or accreditation. When
those requirements are more stringent than the template, the requirements for compliance are
provided in addendum to this manual or in other documents that supplement the manual. This
document structure maintains consistency in the presentation of the quality management system
across the network while providing the location a mechanism to describe and achieve compliance
requirements on a program basis.
1.2.1 Quality Manual Template
The quality manual template is developed by the Corporate Quality Director with contribution
and input from corporate quality personnel and the corporate officers. Approval of the
template by the corporate officers (aka "top management") confirms their commitment to
develop and maintain a quality management system appropriate for the analytical services
offered by the organization and to communicate their expectations of the quality program to
all personnel.
The template and instructions for use of the template are released by corporate quality
personnel to the quality assurance manager responsible for each location (Local QM). The
local QM uses the template to prepare the laboratory's manual by following the instructions
provided. Since the template provides the minimum requirements by which ENV locations
must abide,the laboratory may not alter the font, structure or content of the template except
where specified by instruction to do so. As previously stated,program specific requirements
are provided in addendum or in documents that supplement this manual.
The template is reviewed by corporate quality personnel annually and updated if needed. More
frequent review and revision may be necessary to manage change, to maintain conformance
and compliance to relevant standards,or to meet customer expectations.
See standard operating procedure (SOP) ENV-SOP-CORQ-00015 Document Management and
Control(most recent revision or replacement) for more information.
1.2.2 Laboratory Quality Manual
The manual is approved and released to personnel under the authority of local management
whose signatures are identified on the Manual Signatory Page of this manual. The manual is
reviewed annually, and location specific information is updated, if needed. More frequent
review and revision may be necessary when there are significant changes to the organizational
structure, capabilities,and resources of the laboratory. Review and revision of the manual is
managed by the local QM. If review indicates changes to the main body of the manual are
necessary to maintain conformance and compliance to relevant standards,or to meet customer
expectations, the local QM will notify corporate quality personnel to initiate review and/or
revision of the template.
See SOP ENV-SOP-CORQ-00015 Document Management and Control(most recent revision or
replacement) for more information.

1.2.3 References to Supporting Documents
The template and the manual include references to other laboratory documents that support
the quality management system such as policies and standard operating procedures (SOPs).
These references include the document's document control number and may include the
document title.
This information is subject to change. For example, an SOP may be converted to a policy or
the document's title may change. For these types of administrative changes,the manual and
template are updated to reflect the editorial change during the manual's next scheduled
review/revision cycle or the next time a new version of the manual is released,whichever is
sooner.
The local QM maintains a current list of controlled documents used at each location that
support the quality management system. This list, known as the "Master List", lists each
document used by document control number, title, version, effective date, and reference to

When significant changes to the ENV quality management system are planned,these changes
are managed by corporate quality personnel to assure that the integrity of the quality
management system is maintained.
4.3 Document Control
4.3.1 General
The laboratory's procedures for document control are provided in SOP ENV-SOP-CORQ-
0015 Document Management and Control(most recent revision or replacement).
The laboratory uses electronic document management software (eDMS) to carry out the
document control procedures of the SOP. eDMS automates the process for unique document
identification, version control, approval, access, and archival. The eDMS software used by
ENV restricts access to archived documents except to authorized users to prevent the use of
obsolete documents.
The local QM maintains a master list of controlled documents used at the laboratory. The
master list includes the document control number,document title,and current revision status
and is made available to personnel for their reference.
See SOP ENV-SOP-CORQ-0015 Document Management and Control(most recent revision or
replacement) for more information.

4.3.2 Document Approval and Issue
Documents that support the quality management system are reviewed by qualified personnel
and approved by laboratory management prior to release for general use.
Only the approved versions of documents are available to personnel for use unless use of a
draft document is authorized by management.
See SOP ENV-SOP-CORQ-0015 Document Management and Control(most recent revision or
replacement) for more information.
4.3.3 Document Review and Change
Unless a more frequent review is required by regulatory,certification or accreditation program
the laboratory formally reviews documents at least every two years to ensure the document
remains current,appropriate,and relevant.
Documents are also informally reviewed every time the document is used. Personnel are
expected to refer to and follow instructions in controlled documents when they carry out their
work activities. Consequently,any concerns or problems with the document should be caught
and brought to the attention of laboratory management on an on-going basis.
Documents are revised whenever necessary to ensure the document remains usable and
correct. Older document versions and documents no longer needed are made obsolete and
archived for historical purposes.
ENV does not allow hand-edits to documents. If an interim change is needed pending re-
issue of the document, the interim change is communicated to those that use the document
using a formal communication channel, such as SOP Change in Progress form, email, or
memorandum.
The document review, revision, and archival process is managed by quality personnel at the
location from which the document was released using the procedures established in SOP
ENV-SOP-CORQ-0015 Document Management and Control (most recent revision or
replacement).
4.4 Analytical Service Request,Tender, and Contract Review
The laboratory's management and/or client service personnel perform thorough reviews of requests
and contracts for analytical services to verify the laboratory has the capability,capacity,and resources
necessary to successfully meet the customer's needs. These review procedures are described in
laboratory SOP ENV-SOP-GBAY-0006,Sample Management and Review of Analytical Requests.
The proceduresSOP(s)in this SOP s) are established to ensure that:
■ The laboratory understands the purpose of data collection in order to ensure the test methods
requested are appropriate for the intended use of the data and capable of meeting the client's data
quality objectives;
• The laboratory and any subcontractor has the capability, capacity, and resources to meet the
project requirements and expectations within the requested time frame for delivery of work
product;
■ Any concerns that arise from review are discussed and resolved with the client;and
Page 25 of 100

• The results of review and any correspondence with the client related to this process and/or any
changes made to the contract are recorded and retained for historical purposes.
Capability review confirms that the in-network laboratories and any potential subcontractors hold
required certification/accreditation for the test method,matrix,and analyte and verifies the laboratory
can achieve the client's target compound list and data quality objectives (DQOs) for analytical
sensitivity and reporting limits, QA/QC protocol, and hardcopy test report and electronic data
deliverable (EDD) formats.
Capacity review verifies that the in-network laboratories and any potential subcontractors are able to
handle the sample load and deliver work production within the delivery timeframe requested.
Resource review verifies that the laboratory and any potential subcontractors have adequate qualified
personnel with the skills and competency to perform the test methods and services requested and
sufficient and proper equipment and instrumentation needed to perform the services requested.
4.5 Subcontracting and In-Network Work Transfer
The terms `subcontract' and "subcontracting" refers to work sent to a business external to Pace
Analytical Services,LLC (PAS) and the term`subcontractor'refers to these external businesses,which
are also called vendors.
Work transferred within the ENV network is referred to as interregional work orders (IRWO) and
network laboratories are referred to as IRWO,IR,or a network laboratory.
The network of ENV laboratories offers comprehensive analytical capability and capacity to ensure
PAS can meet a diverse range of client needs for any type of project. If the laboratory receives a
request for analytical services and it cannot fulfill the project specifications, the laboratory's client
services team will work with the client to place the work within the ENV network. When it is not
possible to place the work within network, the laboratory will, with documented client approval,
subcontract the work to a subcontractor that has the capabilities to meet the project specifications
and can meet the same commitment agreed on between the laboratory and the client. Some client
programs require client consent even for in-network work transfer, and when this applies, the client
services team obtains consent as required. The laboratory retains the record of client notification and
their consent in the project record for historical purposes.
Whenever work is transferred to a subcontractor or an in-network laboratory, the laboratory
responsible for management of the project verifies each of these qualifications:
■ The subcontractor or in network laboratory has the proper accreditation/certifications required
for the project and these are current;and
■ The use of the subcontractor or in network laboratory is approved by the client and/or regulatory
agency,when approval is required. Record of approval is retained in the project record.
All subcontractor laboratories must maintain a quality management system like ENV and that
complies with ISO/IEC 17025 and the TNI Standard(s).
Page 26 of 100

ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT 02021-2023 Pace Analytical Services,LLC.
ENV also evaluates and pre-qualifies subcontractors as part of the company's vendor qualification
program. The complete list of approved vendors is maintained by the corporate procurement
department and is made available to all ENV locations. Pre-qualification of a subcontractor does not
negate the requirement for the placing laboratory to verify the capability, capacity, and resources of
any selected subcontractor on a project-specific basis to confirm the subcontractor can meet the
client's needs.
For both subcontracting and in-network work transfer, the project specifications are always
communicated to the subcontractor or the in-network laboratory by the project manager so that the
laboratory performing the work is aware of and understands these requirements.
The procedures for subcontracting are outlined in laboratory SOP ENV-SOP-GBAY-0005,
Subcontracting Samples.
�
4.6 Purchasing Services and Supplies
Vendors thatprovide services and supplies to the laboratoryare pre qualified to verifythe vendor's
pP p q
capability to meet the needs of PAS. These needs include but are not limited to competitive pricing,
capacity to fill purchase orders, quality of product, customer service, and business reputation and
stability. The records of vendor evaluation and the list of approved vendors is maintained by the
corporate procurement department.
The procedures for vendor qualification are specified in the corporate process for vendor
qualification,however named.
The laboratory may purchase goods and services from any supplier on the approved vendor list.
The specifications (type,class,grade,tolerance,purity,etc.) of supplies,equipment,reagents,standard
reference materials and other consumables used in the testing process are specified in SOPs. The
SOP specifications are based on the governing requirements of the approved reference methods and
any additional program driven regulatory specification, such as drinking water compliance. All
requisitions for materials and consumables are approved by the department supervisor to confirm the
purchase conforms with specified requirements. After approval the requisition is handled by the
laboratory's designated purchasing agent. On receipt, the product is inspected and verified before
use,when applicable.
The laboratory's procedure for the purchase of services and supplies is specified in laboratory SOP
ENV-SOP-GBAY-0145,Laboratory Supply Procedures.
4.7 Customer Service
Project details and management is handled by the laboratory's customer service team. Each customer
is assigned a Project Manager (PM) that is responsible for review of contract requirements and
handling laboratory to customer communication about the project status.
4.7.1 Commitment to Meet Customer Expectations
The laboratory cooperates and works closely with our customers to ensure their needs are met
and to establish their confidence in the laboratory's capability to meet their needs for analytical
services and expectations for service.
Page 27 of 100

The PM is the customer's primary point of contact for each analytical service request. The
PM gathers information from the customer to ensure the details of their request are
understood.After samples are received,the PM monitors the progress of the project and alerts
the customer of any delays or excursions that may adversely impact data usability. Laboratory
supervisors are expected to keep the PM informed of project status and any delays or major
issues,so that the PM can keep the client informed.
The laboratory encourages customers to visit the laboratory to learn more about the
laboratory's capabilities,observe performance and to meet laboratory personnel.
ENV customers expect confidentiality. Laboratory personnel will not divulge or release
information to a third party without proper authorization unless the information is required
for litigation purposes. See Section 4.1.5.4 of this manual and policy COR-POL-0004 Ethics
Policy for more information on the laboratory's policy for client confidentiality.
4.7.2 Customer Feedback
The laboratory actively seeks positive and negative feedback from customers through surveys
and direct communication. Information from the client about their experience working with
the laboratory and their satisfaction with workproduct is used to enhance processes and
practices and to improve decision making. Customer feedback is communicated to laboratory
management and corporate personnel in management reports and analyzed yearly during
management review (See 4.15) to identify risk and opportunity. Corrective, preventive, or
continuous improvement actions are taken based on nature of and/or feedback trends.
Also see sections 4.9,4.10,4.11,4.12,4.14,and 4.15 for more information about how customer
feedback is managed by the laboratory and used to enhance the quality management system.
4.8 Complaints
Complaints provide opportunities to improve processes and build stronger working relationships with
our clients.
The laboratory's complaint resolutionprocess includes three steps. First, handle and resolve the
r3' P P
complaint to mutual satisfaction. Second,perform corrective action to prevent recurrence (See 4.11).
Third,record and track the complaint and use these records for risk and opportunity assessment and
preventive action (See 4.12).

4.9 Nonconforming Work
4.9.1 Definition of Nonconforming Work
Nonconforming work is work that does not conform to customer requirements, standard
specifications,laboratory policies and procedures,or that does not meet acceptance criteria.
The discovery of non-conforming work comes from various sources which include, but are
not limited to:
• results of quality control samples and instrument calibrations;
• quality checks on consumables and materials;
• general observations of laboratory personnel;
• data review;
• proficiency testing;
• internal and external audits;
• complaints and feedback;
• management review and reports;and
• regulatory and certification and accreditation actions.
The way in which the laboratory handles nonconforming work depends on the significance
and impact(risk) of the issue. Some issues may simply require correction,others may require
investigation, corrective action(See 4.11) and/or data recall(See 4.16). When the laboratory
releases data and test results associated with nonconforming QC and acceptance criteria, test
results are qualified, or non-conformances are noted in the final analytical report to apprise
the data user of the situation. (See 5.10)
Nonconforming work also includes unauthorized departure from laboratory policies,
procedures and test methods. Authorized departures are explained in the following
subsections. Situations that do not conform to these conditions are considered unauthorized
departure(s).
4.9.1.1 Authorized Departure from SOP
An authorized departure from a test method SOP is one that has been reviewed and
approved by the Department Manager,designated Acting Technical Manager for TNI
for the discipline the SOP pertains to (Chemistry, Inorganic Chemistry,
Microbiology), Quality Manager, or the General Manager. Management review is
conducted to confirm the departure does not conflict with regulatory compliance
requirements for which the data will be used or does not adversely affect data integrity.
The departure may originate from client request or may be necessary to overcome a
problem.
An authorized departure from administrative or process-oriented SOP is typically
necessary to correct an error in the SOP. These departure requests are reviewed and
pre-approved by the QA Manager.
Page 29 of 100

a
ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT 0 2021-2023 Pace Analytical Services,LLC.
Documentation of SOP departures and approval decisions are retained by the
laboratory as evidence that the departure was authorized.When necessary,approved
departures from test method SOPs are noted in the final test report to advise the data
user of any ramification to data quality.
4.9.1.2 Authorized Departure from Test Methods (Method Modifications)
When test results are associated to a published reference test method,the laboratory's
test method SOP must be consistent with the test method. If the test method is
mandated for use by a specific regulatory program such as drinking water or
wastewater or a certification or accreditation program, such as TNI/NELAC, the
SOP must also comply with or include these requirements. If the procedures in the
SOP are modified from the test method,these modifications must be clearly identified
in the SOP. The conditions under which the laboratory may establish an SOP that
is modified from these reference documents, and what is considered a modification
are specified in ENV-SOP-CORQ-0011 Method Validation and Instrument Verification
(most recent revision or replacement).
Modifications that do not meet the requirements of this SOP (ENV-SOP-CORQ-
0011) are unauthorized. Client requests to deviate from the test method are handled
as client requests to depart from the test method SOP since it is the SOP that the
laboratory follows when performing work.
4.9.1.3 Stop Work Authority
Stop Work Authority provides laboratory personnel with the responsibility and
obligation to stop work when there is a perceived unsafe condition or behavior that
may result in an unwanted event.
All laboratory and corporate personnel have the authority to stop work when needed
to preserve data integrity or safety of workers.
Once a stop work order has been initiated and the reason for doing so is confirmed
valid;laboratory management is responsible for immediate correction and corrective
action (see section 4.11) before resumption of work.
Laboratory management refers to the positions listed as key personnel in section
4.1.5.1.1 of this manual.
For stop work orders related to safety,the decision to resume to work after correction
or corrective action may be made by the Chief Compliance Officer,the EHS Director,
and the General Manager or the designees for these positions.
For stop work orders related to data integrity, the decision to resume to work after
correction or corrective action may be made by the Chief Compliance Officer, the
Corporate Quality Director, the Corporate Program Manager, the local Quality
Manager or the designees for these positions.
4.10 Continuous Improvement
The laboratory's quality management system is designed to achieve continuous improvement through
the implementation of the quality policy and objectives outlined in this manual. Information about

the laboratory's activities and performance is gained from many sources such as customer feedback,
audits, QC, trend analysis, business analytics, management reports, proficiency testing, and
management systems review. This information is subsequently used during the laboratory's corrective
action (see section 4.11) and preventive action(see section 4.12) processes and during annual review
of the management system (see section 4.15) to establish goals and objectives for improvement.
ENV also promotes a continuous improvement culture based on the principles of lean manufacturing.
These principles include 3P (Process,Productivity,Performance) and Kaizen. 3P is a platform used
by Pace to share best practices and standardization across the network to achieve operational
excellence. Kaizen is a team-based process used to implement tools and philosophies of lean to
reduce waste and achieve flow with the purpose of improving both external and internal customer
satisfaction.
4.11 Corrective Action
Corrective action is a process used to eliminate the cause of a detected nonconformity. It is not the
same as a correction. A correction is an action taken to fix an immediate problem. The goal of the
corrective action process is to find the underlying cause(s) of the problem and to put in place fixes to
prevent the problem from happening again. The corrective action process, referred to as CAPA by
ENV, is one of the most effective tools used by the laboratory to prevent nonconforming work,
identify risk and opportunity,and improve service to our customers.
The laboratory has two general processes for corrective action:
The process used for actions taken in response to day to day quality control (QC) and acceptance
criteria exceptions (nonconformance) that occur during the day to day testing process are called
corrections.These events do not usually include formal methods for cause analysis;instead the reason
for the failure is investigated through troubleshooting or other measures. Required actions for
correction of routine nonconformance is specified in laboratory SOPs. When corrective action is not
taken, cannot be taken,or is not successful,test results associated with the nonconforming work are
qualified in the final test report.Documentation of the nonconformance and corrective action taken
is documented in the analytical record.
A 7-stage corrective action process is used when there is a problem or departure from the quality
management system,technical activities,or when the extent of a single problem has significant impact
on data, regulatory compliance or customer needs. These problems are identified through various
activities such as but not limited to: quality control trends,internal and external audits,management
review, customer feedback,and general observation.
The laboratory's 7 Stage CAPA Process includes:
1) Identification and Containment
2) Evaluation
3) Investigation
4) Cause Analysis
5) Action Plan
6) Implementation
7) Follow Up and Effectiveness Review
The 7 stage CAPA process may be initiated by any employee. Once the process is initiated it is
overseen and coordinated by laboratory management. The CAPA process is documented using a
software-based workflow process called Qualtrax. The Qualtrax CAPA record includes tracking

information,dates,individuals involved,those responsible for action plan implementation and follow-
up,and timelines and due dates.
ENV's procedures for corrective action, are specified in corporate SOP ENV-SOP-CORQ-0018,
Procedure for Corrective and Preventive Action (most recent revision or replacement). Additional
explanation about certain aspects of the laboratory's corrective action process are outlined in the next
three subsections.
4.11.1 Cause Analysis
Cause analysis is the process of investigation used by the laboratory to identify the underlying
cause(s) of the problem. Once causal factors are identified,ways to mitigate the causal factors
are reviewed and corrective action(s) most likely to eliminate the problem are selected.
The laboratory uses different methods to conduct this analysis.The most common approach
is 5-Why,but fishbone diagrams,or even brainstorming may be appropriate depending on the
situation. The method used is documented in the CAPA record.
4.11.2 Effectiveness Review
Monitoring corrective actions for effectiveness is an activity shared by laboratory supervisors
and quality assurance personnel. Effectiveness means the actions taken were sustainable and
appropriate. Sustainable means the change is still in place. Appropriate means the action(s)
taken prevented recurrence of the problem since the time corrective action was taken.
The timeframe in which effectiveness review takes place depends on the event and is recorded
in the CAPA record with anyaddition
a on actions that need to be taken.
Corrective action trends are also monitored by laboratory management and used to identify
opportunities for preventive action or to gain lessons learned when actions taken were not
adequate to solve the problem. See Section 4.12 (Preventive Action) and 4.15 (Management
Review) for more information.
4.11.3 Additional Audits
When non-conformities or other problems cast doubt on compliance with the laboratory's
policies,procedures,or compliance to regulatory requirements;the quality manager schedules
a special audit of the area of activity in accordance with Section 4.14.1 as soon as possible.
These special audits are used to determine the scope of the problem and to provide
information for the CAPA process. Additional full-scale audits are done when a serious issue
or risk to the laboratory's business is identified.
4.12 Preventive Action
Preventive action is an action taken to eliminate the cause of a potential nonconformity and to achieve
improvement.Preventive action is a forward-thinkingprocess designed to prevent problems opposed
to reacting to them (corrective action).
Some examples of preventative action include,but are not limited to:
! Scheduled instrument maintenance (Preventative maintenance)
! Addition of Staff and Equipment
! Professional Development Activities
Page 32 of 100

aceAnalytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC

! Implementation of New Technology
The laboratory looks for opportunities for preventive action from a variety of sources including but
not limited to: employee idea's,customer feedback,business partners input, trend analysis,business
analytics,management reviews,proficiency testing results,lean management events, and risk-benefit
analysis.
Laboratory management evaluates the success of preventive actions taken in any given year during
annual management review. See Section 4.15 for more information.
4.12.1 Change Management
Preventive actions may sometimes result in significant changes to processes and procedures
used by the laboratory.Laboratory management evaluates the risks and benefits of change and
includes in its implementation of change process, actions to minimize or eliminate any risk.
The types of changes for which risk are considered and managed include: infrastructure
change, change in analytical service offerings, certification or accreditation status,
instrumentation,LIMS changes,and changes in key personnel.
4.13 Control of Records
A record is a piece of evidence about the past, especially an account of an act or occurrence kept in
writing or some other permanent form. Laboratory records document laboratory activities and
provide evidence of conformity to the requirements established in the quality management system.
These records may be hardcopy or electronic on any form of media.
4.13.1 General Requirements
4.13.1.1 Procedure
The requirements for control of records is specified in corporate policy ENV-POL-
CORQ-0013 Record Management. The procedure used to implement the policy is
described in laboratory SOP ENV-SOP-CORQ-0015 Document Management and Control
(most recent revision or replacement) and ENV-SOP-GBAY-0119 Data and Records
Archival(most recent revision or replacement).
The policy is established to assure quality and technical records are identified,retained,
indexed,and filed to allow for retrieval during the entire retention time frame.During
storage,records are kept secure and protected from deterioration. At the end of the
retention time, the records are disposed of properly in order to maintain client
confidentiality and to protect the interests of the company.
In general, laboratory records fall into three categories: quality, technical, and
administrative.
Examples of each are provided in the following table:

4.13.1.2 Record Legibility and Storage
Records are designed to be legible and to clearly identify the information recorded.
Manual entries are made in indelible ink;automated entries are in a typeface and of
sufficient resolution to be read. The records identify laboratory personnel that
performed the activity or entered the information. Records are archived and stored
in a way that they are retrievable. Access to archived records is controlled and
managed.
For records stored electronically, the capability to restore or retrieve the electronic
record is maintained for the entire retention period. Hardcopy records are filed and
stored in a suitable environment to protect from damage, deterioration, or loss.
Hardcopy records may be scanned to PDF for retention. Scanned records must be
checked against the hardcopyto verifythe scan is complete and legible.
Administrative records are kept for a minimum of 5 years and technical and quality
records are kept for 10 years unless otherwise specified by the client or regulatory
program.
The date from which retention time is calculated depends on the record. In general,
the retention time of technical records of original observation and measurement is
calculated from the date the record is created. If the technical record is kept in a
chronological logbook, the date of retention may be calculated from the date the
logbook is archived.The retention time of test reports and project records,which are
considered technical records, is calculated from the date the test report was issued.
The retention time of quality records is usually calculated from the date the record is
archived.
Refer to the record management policy and the laboratory SOP for more information.
4.13.1.3 Security
The laboratory is a secure facility and access to records is restricted to laboratory
personnel.
4.13.1.4 Electronic Records
The data systems used to store electronic records is backed up in accordance with
laboratory SOP ENV-SOP-GBAY-0162 Electronic Records Backup (most recent
revision or replacement). Access to archived records stored electronically is
maintained by personnel responsible for management of the electronic system.

4.13.1.5 Electronic Signature Policy
Work done by ENV locations include activities that require the application of a
signature. Some of this work product is in electronic format and signatures are
applied electronically.
The Electronic Signatures in Global and National Commerce Act (E-Sign Act)
clarifies that electronic signatures are legally valid and enforceable under United States
law.
ENV's policy for use and application of electronic signatures is specified in corporate
policy ENV-POL-CORQ-0014 Electronic Signature Policy.
All employees of ENV, including temporary and contract personnel, must sign an
Electronic Signature Agreement to acknowledge that they understand and accept that
work activities performed by them may be authenticated with application of an
electronic signature and that electronic signature has the same validity as a
handwritten signature. Their signed agreement also confirms the individual has read
and understands the policy and agrees to abide by the requirements for use of
electronic signature stated in the policy.
4.13.2 Technical Records
In addition to the requirements specified in subsections 4.13.1.1 through 4.13.1.5, the
requirements in the following subsections also apply to technical records.
4.13.2.1 Description
Technical records are the accumulation of data and information generated from the
analytical process. These records may include forms, worksheets, workbooks,
checklists, notes, raw data, calibration records, final test reports, and project record.
The accumulated record essentially needs to provide adequate detail to historically
reconstruct the process and identify the personnel that performed the tasks associated
with a test result.
4.13.2.2 Real Time Recordkeeping
Personnel are instructed and expected to always record observations, data, and
calculations at the time they are made. Laboratory managers are responsible to assure
that data entries,whether made electronically or on hardcopy, are identifiable to the
task.
4.13.2.3 Error Correction
Errors in records must never be erased, deleted or made illegible. Use of correction
fluid, such as white-out is prohibited. In hardcopy records,the error is corrected by
a single strike through the original entry and the new entry recorded alongside or
footnoted to allow for readability. Corrections are initialed and dated by the person
making the correction. If the correction is not self-explanatory, a reason for the
correction is recorded.
For electronic records, equivalent measures of error correction or traceability of
changes made is kept. For example,audit trails provide records of change.
Page 35 of 100

ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
Maintenance of proper practices for error correction is monitored through the tiered
data review process described in Section 5.9.3. Laboratory records are reviewed
throughout the data review process. Individuals performing these reviews flag errors
that are not properly corrected and bring these to the attention of the department
manager or supervisor of the work area in which the record was generated so that the
problem may be addressed and corrected with the individual(s) that did not make the
correction properly.
4.14 Audits
The laboratory performs internal systems and technical audits to assess implementation of the QMS
and compliance to this manual and to procedures,such as policy,SOP and SWI. Since the processes
in this manual are based on the relevant quality system standards and regulatory and
accreditation/certification program requirements the laboratory provides services for, the internal
audits also assess on-going compliance to these programs.
The laboratory is also audited by external parties such as regulatory agencies, customers,consultants
and non-government assessment bodies (NGAB).
Information from internal and external audits is used by laboratory management to address
compliance concerns and opportunities where improvement will increase the reliability of data.
Deficiencies,observations and recommendations from audits are managed by the local QM using the
laboratory's formal CAPA process. See Section 4.11 for more information.
4.14.1 Internal Audit
The laboratory's internal audit program is managed by the local QM in accordance with an
audit plan established at the beginning of each calendar year. The schedule is prepared to
assure that all areas of the laboratory are reviewed over the course of the year. Conformance
to the schedule is reported to both laboratory management and corporate quality personnel in
a monthly QA report prepared by the quality manager.
Although the local QM creates the audit schedule, it is the shared responsibility of local
management to assure the schedule is maintained. Laboratory supervisors cooperate with the
quality personnel to provide the auditors with complete access to the work area, personnel,
and records needed.
Internal audits are performed by personnel approved by the quality manager. In general,
personnel may not audit their own activities unless it can be demonstrated that an effective
and objective audit will be carried out. The auditor must be trained, qualified, and familiar
enough with the objectives,principles,and procedures of laboratory operations to be able to
perform a thorough and effective evaluation.
The laboratory's internal audit program ensures daily practice is consistent with laboratory's
SOPs and to verify SOPs are compliant with policy and procedures. Test reports are audited
to verify the final product is consistent with customer/project requirements, the work was
carried out in accordance with policy and SOPs, the SOP complies with the cited reference
method,test results are accurate,and of known and documented quality and properly qualified,
when necessary.
Special audits are performed ad hoc to follow up on a specific issue such as a client complaint,
negative feedback,concerns of data integrity or ethics,or a problem identified through other

audits. Special audits may be scheduled or unscheduled. Unscheduled internal audits are
conducted whenever doubts are cast on the laboratory's compliance with regulatory
requirements or its own policies and procedures. These unscheduled internal audits may be
conducted at any time and may be performed without an announcement to laboratory
personnel.
When observations and findings from any audit(internal or external) cast doubt on the validity
of the laboratory's testing results,the laboratory takes immediate action to initiate investigate
the problem and take corrective action. (Also see 4.11 and 4.16)
The laboratory's internal audit program and auditing procedures are further described in
laboratory SOP ENV-SOP-GBAY-0108 Internal and External Audits(most current revision or
replacement.
4.14.1.1 Corporate Compliance Audit

with corporate management to highlight focus areas for improvement in addition to areas in which
the laboratory has excelled.
4.16 Data Integrity
ENV's procedures for the investigation and response to events that may affect data integrity are
described in the corporate SOPs for data inquiries and data recall and corrective and preventive action,
however named.
Customers whose data are affected by these events are notified in a timely manner,usually within 30
days after the impact of the problem is understood. Some accreditation programs also require
notification to the accreditation body (AB) within a certain timeframe from date of discovery when
the underlying cause of the issue impacts accreditation. The laboratory follows any program or project
specific client notification requirements for notification,when applicable.

analyzed by the test methods they perform.After successful IDOC,
the employee must demonstrate continued proficiency(CDOC) for
the test method on an annual basis. If more than a year has passed
since the employee last performed the method;then capability must
be re-established with an IDOC.
Records of IDOC and CDOC are kept in the employee's training
file.
5.2.2.2 Effectiveness of Training
The results of the performance measures used to identify training needs are the same
measures used by the laboratory to measure effectiveness of the training program.
Improvement in key performance measures suggest the training program is successful
(See 5.2.2.1).
Effectiveness of individual employee training is measured by their demonstrated
ability to comprehend the training material and apply knowledge and skills gained to
their job task. Measurements include but are not limited to:
• Testing of the employee's knowledge of the quality management system,policies,
and technical and administrative procedures through various mechanisms, such
as quizzes,observation,and interviews.
• Demonstrated ability to convey information correctly and factuallyin written and
verbal communication to internal and external parties.

their development of administrative and technical skills.These learning objectives and
materials, referred to as Learning Plans (LP), are created and maintained by ENV's
3P program and managed by the employee's direct supervisor.
In addition to LPs, PAS maintains a wide variety of supplemental learning courses
that are made available to all PAS employees for professional development. These
learning materials,maintained by PAS's corporate training personnel,are accessed via
the company's employee portal, PaceConnect. The learning may be self-initiated
based on an employee's interest or may be assigned to the employee at the discretion
of management as professional development as part of an employee's annual
goals. Supplemental learning courses and learning plan activities are not prerequisites
for competency (Section 5.2.1.1) and are not part of the required QMS training
specified in Section 5.2.2.1.
5.2.3 Personnel Supervision
Every employee is assigned a direct supervisor,however named,who is responsible for their
supervision. Supervision is the set of activities carried out by the supervisor to oversee the
progress and productivity of the employees that report to them.
General supervisory responsibilities may include but are not limited to:
■ Hiring Employees
■ Training Employees

monitored by laboratory staff. All visitors must sign a visitor's log,and a staff member must
accompany them during the duration of their stay.
5.3.5 Good Housekeeping
The laboratory ensures good housekeeping practices in work areas to maintain a standard of
cleanliness necessary for analytical integrity and personnel health and safety. Minimally,these
measures include regular cleaning of the work area. Where necessary, areas are periodically
monitored to detect and resolve specific contamination and/or possible safety issues.
5.4 Test Methods
5.4.1 General Requirements
The laboratory uses test methods and procedures that are appropriate for the scope of
analytical services the laboratory offers.
Instructions on the use and operation of equipment and sample handling, preparation, and
analysis of samples are provided in SOPs. The instructions in SOPs may be supplemented
with other documents including but not limited to,standard work instructions (SWI),manuals,
guides,project documents and reference documents.
These documents are managed using the procedures described in SOP ENV-SOP-CORQ-
0015 Document Management and Control(most recent revision or replacement) and SOP ENV-
SOP-CORQ-0016 Standard Operating Procedures and Standard 'Work Instructions (most recent
revision or replacement).
5.4.2 Method Selection
The test methods and protocols used by the laboratory are selected to meet the needs of the
customer, are appropriate for the item tested and intended use of the data, and to conform
with regulatory requirements when regulatory requirements apply.
In general,the test methods offered are industry accepted methods published by international,
regional, or national standards. The laboratory bases its procedure on the latest approved
edition of a method unless it is not appropriate or possible to do so, or unless regulatory
requirements specify otherwise.
The laboratory confirms that it can perform the test method and achieve desired outcome
before analyzing samples (see section 5.4.5). If there is a change in the published analytical
method,then the confirmation is repeated.
When a customer does not specify the test method(s) to be used,the laboratory may suggest
test methods that are appropriate for the intended use of the data and the type of samples to
be tested. The laboratory will also inform customers when test methods requested are
considered inappropriate for their purpose and/or out of date. This discourse takes place
during review of analytical service requests (See Section 4.4).
5.4.3 Laboratory Developed Methods
A laboratory developed method is a method developed from scratch (no published source
method), a procedure that modifies the chemistry from the source method, or a procedure
that exceeds the scope and application of the source method.
Page 46 of 100

Laboratory developed methods must be validated prior to use (see section 5.4.5) and the
procedure documented in a test method SOP.
The requirements for non-standard methods(Section 5.4.4)also apply to laboratory developed
methods. 1
5.4.4 Non-standard Methods
A non-standard method is a method that is not published or approved for use by conventional
industry standards for the intended purpose of the data. Non-standard methods must be
validated prior to use (see section 5.4.5) and the procedure developed and documented in a
test method SOP.
At a minimum,the following information must be included in the procedure:
• Title/Identification of Method;
• Scope and Application;
• Description of the type of item to be analyzed;
• Parameters or quantities and ranges to be determined;
• Apparatus and equipment,including technical performance requirements;
• Reference standards and reference materials required;
• Environmental conditions required and any stabilization period needed;and
• Description of the procedure,including:

Use of a non-standard method for testing must be agreed upon with the customer. The
agreement, which is retained by the laboratory in the project record, must include the
specifications of the client's requirements, the purpose of testing,and their authorization for
use of the non-standard method.
5.4.5 Method Validation
5.4.5.1 Validation Description
Validation is the process of conformation and the provision of objective evidence
that the stated requirements for a specific method/procedure are fulfilled.
Page 47 of 100

'ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
The laboratory's requirements and procedures for method validation are outlined in
SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(most recent
revision or replacement).
5.4.5.2 Validation Summary
All test methods offered by the laboratory are validated before use to confirm the
procedure works and the data and results achieved meet the goals for the method and
repeated when there are major changes to the laboratory procedure.
Results of validation are retained are kept in accordance with method validation SOP
and the corporate policy ENV-CORQ-POL-0013 Record Management (most recent
revision or replacement).
5.4.5.3 Validation of Customer Need
The validation process includes review of accuracy, precision, sensitivity, selectivity,
linearity, repeatability, reproducibility, robustness, and cross-sensitivity of the
procedure against general customer needs to ensure the laboratory's procedure will
meet those needs.
The following subsections highlight some of these concepts:
5.4.5.3.1 Accuracy
Accuracy is the degree to which the result of a measurement,
calculation, or specification conforms to the correct value or a
standard. When the result recovers within a range from the known
value (control limit); the result generated using the laboratory's test
method SOP is considered accurate.
5.4.5.3.2 Precision
Precision refers to the closeness of two or more measurements to
each other. It is generally measured by calculating the relative
percent difference (RPD) or relative standard deviation(RSD) from
results of separate analysis of the same sample. Precision provides
information about repeatability, reproducibility, and robustness of
the laboratory's procedure.
5.4.5.3.3 Limits of Detection(LOD) (Chemistry)
The LOD is the minimum result which can be reliably discriminated
• from a blank with a predetermined confidence level. The LOD
establishes the limit of method sensitivity and is also known as the
detection limit(DL) or the method detection limit(MDL).
Values below the LOD cannot be reliably measured and are not
reported by the laboratory unless otherwise specified by regulatory
program or test method.
The LOD is established during method validation and after major
changes to the analytical system or procedure that affect sensitivity
are made.
Page 48 of 100

'ace Analytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
5.4.5.3.4 Limits of Quantitation (LOQ) and Reporting Limit (RL)
The LOQ is the minimum level, concentration, or quantity of a
target analyte that can be reported with a specified degree of
confidence. The LOQ is established at the same time as the LOD.
The LLOQ is the value of the lowest calibration standard included
in the calibration curve. The LLOQ establishes the lower limit of
quantitation.
The LOQ and LLOQ represent quantitative sensitivity of the test
method.
■ The LOQ must always be equal to or greater than the LLOQ
and the LLOQ must always be greater than the LOD.
• Any reported value (detect or non-detect) less than the LLOQ
is a qualitative value.
The RL is the value to which the presence of a target analyte is
reported as detected or not detected. The RL is project-defined
based on project data quality objectives (DQO). In the absence of
project specific requirements, the RL is usually set to the LOQ or
the LLOQ.
The laboratory's procedures for LOD/LOQ determination is
detailed in laboratory SOP ENV-SOP-GBAY-0106,Determination of
the LOD and LOQ.
The local SOP is based on guidance provided by corporate quality
and must comply with 40CFR 136 Appendix B and the TNI
Standard.
5.4.5.3.5 Linearity
Linearity is a mathematical concept applied to calibration models
that employ multiple points to establish a calibration range used for
quantitative analysis. Linearity is measured differently based on the
calibration model. In general, if linearity is demonstrated then the
slope of the response of standards are sufficiently close to one
another. The accuracy of the linear regression and non-linear curves
is verified by checking percent error or relative standard error(RSE),
which is the process of refitting calibration data back to the model
to determine if the results are accurate. For linear curves that use
average calibration or response factor, error is measured by relative
standard difference (RSD).
Linearity also establishes the range of quantitation for the test
method used which directly impacts the sensitivity of the test
method and uncertainty in measurement results. As previously
noted, the LLOQ establishes the lower limit of quantitation.
Similarly, the upper range of linearity establishes the upper limit of
Page 49 of 100

t2eAnaIjicaI
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
quantitation. In general,results outside of this range are considered
qualitative values. However, some inorganic methods allow for
extension of the linear range above the upper limit of quantitation
when accuracy at this value is verified.
Linearity can also be used to establish repeatability, reproducibility,
and robustness of the laboratory's test method. When linearity is
demonstrated using a specific calibration model during method
validation, then use of this same calibration model to achieve
linearity on a day to day basis confirms the laboratory's method is
repeatable,reproducible,and robust.
5.4.5.3.6 Demonstration of Capability(DOC)
The DOC performed during method validation confirms that the
procedure demonstrated acceptable precision and accuracy. The
procedure used for DOC for method validation is the same as
described in section 5.2.2.1.5 for demonstration of analyst capability.
5.4.6 Measurement Uncertainty
The laboratory provides an estimate of uncertainty in testing measurements when required or
on client request. In general, the uncertainty of the test method is reflected in the control
limits used to evaluate QC performance. (See 5.9.1.1.9). ISO/IEC supports this concept with
language that reads when a well-recognized test method specifies limits to the values of the
major source of uncertainty of measurement and specifies the form of presentation of
calculated results, the laboratory has satisfied the requirements on analytical uncertainty by
following the test method and reporting instructions.
When measurement uncertainty cannot be satisfied through control limits,the laboratory will
provide a reasonable estimation of uncertainty. A reasonable estimation is based on
knowledge of method performance and previous experience. When estimating the analytical
uncertainty, all uncertainty components which are of importance in the given situation are
taken into account.

5.6 Measurement Traceability
5.6.1 General
Measurement traceability refers to a property of a measurement result whereby the result can
be related to a reference through an unbroken chain of calibration, each contributing to the
measurement uncertainty. Traceability requires an established calibration hierarchy of
equipment (instruments) used during testing including equipment used for subsidiary
measurements. The laboratory assures this equipment is calibrated prior to being put into
service and that the reference standard and materials used for calibration are traceable to the
international standard of units (SI) or national measurement standard.
When strict traceability to SI units cannot be made,the laboratory establishes traceability with
the use of reference standards and equipment obtained from competent suppliers that provide
calibration certificates and/or certificates of analysis (COA).
5.6.2 Equipment Correction Factors
When correction factors are used to adjust results the laboratory will assure that results in
computer software are also updated. For example,if the direct instrument or reading output
must be corrected based on preparation factor or concentration factors, laboratory
management will assure the corrected result is also updated in the software.
5.6.3 Specific Requirements
5.6.3.1 Requirements for Calibration Laboratories
The laboratory does not offer calibration services to customers.
5.6.3.2 Requirements for Testing Laboratories
The laboratory has procedures in place to verify equipment is calibrated prior to being
put into service (See 5.5.2) and ensures the reference standard and materials used for
calibration are traceable to the international standard of units (SI) or national
measurement standard. When strict traceability to SI units cannot be made, the
laboratory establishes traceability with the use of reference standards and equipment
obtained from competent suppliers that provide calibration certificates and/or
certificates of analysis (COA).
5.6.4 Reference Standards and Reference Materials
5.6.4.1 Reference Standards
The laboratory uses reference standards of measurement to verify adequacy of
working weights and thermometers. The working weight is the weight(s) used for
daily balance calibration checks and the working thermometers are used for
temperature measurements on a daily basis.
Intermediate checks of the working reference measurement standards are performed
to verify adequacy between calibration from an external calibration laboratory. The
measurements from working weights and thermometers are compared to
measurements taken by the reference standard which is traceable to SI or a national
Page 55 of 100

standard. The reference weights and thermometers are used solely for verification
purposes unless the laboratory can prove that daily use does not adversely affect
performance of the reference standard.
The laboratory performs intermediate checks of the working weights at least annually.
Working thermometers (glass and digital) are checked against the reference
thermometer prior to placement in service to establish a correction factor and then
rechecked annually(glass) or quarterly(digital) thereafter.
The calibration of liquid in glass reference thermometers is verified every 5 years and
the calibration of digital reference thermometers is verified annually by an ISO/IEC
17025 accredited calibration laboratory or service provider that provides traceability
to a national standard.
The calibration of the reference weight(s) is verified every 5 years by an ISO/IEC
17025 accredited calibration laboratory.
If criteria for the intermediate checks or recertification is not acceptable, the impact
on previously reported results is evaluated using the process for evaluation of
nonconforming work(See 4.9).
See laboratory SOP ENV-SOP-GBAY-0115 SupportEquipment(most recent revision
or replacement)for more information about this process.
5.6.4.2 Reference Materials
The laboratory purchases chemical reference materials (also known as stock
standards) from vendors that are accredited to ISO 17034 or Guide 34. Purchased
reference materials must be received with a Certificate of Analysis (COA) where
available. If a reference material cannot be purchased with a COA,it must be verified
by analysis and comparison to a certified reference material and/or there must be a
demonstration of capability for characterization. COA are reviewed for adequacy and
retained by the laboratory for future reference.
All prepared standards, reference materials, and reagents are verified to meet the
requirements of the test method through routine analyses of quality control samples.
The laboratory procedure for traceability and use of these materials is provided in
laboratory SOP ENV-SOP-GBAY-0145 Laboratory Supply Procedures (most recent
revision or replacement.
This SOP includes each of the following requirements:
• Procedures for documentation of receipt and tracking. The record of entry
includes name of the material,the lot number,receipt date,and expiration date.
• Storage conditions and requirements. Reference materials must be stored
separately from samples, extracts,and digestates.
• Requirements to assure that preparations of intermediate or working solutions
are recorded and assigned a unique identification number for tracking. Records
of preparation include the lot number of the stock standard(s) used,the type and
Page 56 of 100

lot number of the solvent, the formulation, date, expiration date, and the
preparer's initials. The lot number of the working standards is recorded in the
analytical record to provide traceability to the standard preparation record. The
preparation record provides traceability to the COA,which is traceable to SI or
the national measurement standard.
■ A requirement that the expiration dates of prepared standards may not exceed
the expiration date of the parent standard. Standards, reference materials, and
reagents are not used after their expiration dates unless it is not possible to
procure a new standard and the reliability of the expired material is verified and
documented by the laboratory using a procedure approved by corporate quality
personnel. Otherwise, the expired material is promptly removed from the work
area or clearly labeled as acceptable for qualitative/troubleshooting purposes
only.
■ The second source materials used for verification of instrument calibration are
obtained from a different manufacturer or may be a different lot from the same
manufacturer.
• Procedures to check reference materials for degradation and replacement of
material if degradation or evaporation is suspected.
• Procedures for labeling. At a minimum the container must identify the material,
the ID of the material and the expiration date. Original containers should also
be labeled with date opened.
5.6.4.3 Intermediate Checks
Checks to confirm the calibration status of standards and materials are described in
laboratory SOPs. These checks include use of second source standards and reference
materials reserved only for the purpose of calibration checks.
5.6.4.4 Transport and Storage
The laboratory handles and transports reference standards and materials in a manner
that protects the integrity of the materials.Reference standard and material integrity
is protected by separation from incompatible materials and/or minimizing exposure
to degrading environments or materials. Standards and reference materials are stored
separately from samples, extracts, and digestates. All standards are stored according
to the manufacturer's recommended conditions. Temperatures colder than the
manufacturer's recommendation are acceptable if it does not compromise the
integrity of the material (e.g.remains in liquid state and does not freeze solid).In the
event a standard is made from more than a single source with different storage
conditions, the standard will be stored according to the conditions specified in the
analytical method.
See the applicable analytical SOPs for specific reference material storage and transport
protocols.

5.7 Sampling
Sampling refers to the field collection of samples and to subsamples taken by the laboratory for
analysis from the field collected sample.
Subsampling procedures are included in each test method SOP or a stand-alone SOP to assure the
aliquot used for testing is representative of the field collected sample.
The requirements in the following subsections apply when field sampling is performed by the
laboratory.
5.7.1 Sampling Plans and SOPs
When the laboratory performs field collection of samples, sampling is carried out in
accordance with a written sample plan prepared by the customer or by the laboratory and by
relevant sampling SOPs. These documents are made readily accessible at the sampling
location. Sampling plans and SOPs are,whenever reasonable,based on appropriate governing
methods and address the factors to be controlled to ensure the validity of the analytical results.
5.7.2 Customer Requested Deviations
When the customer requires deviations, additions, or exclusions from the documented
laboratory sampling plan and/or procedure,the laboratory records the client's change request
in detail with the sampling record, communicates the change to sampling personnel, and
includes this information in the final test report.
5.7.3 Recordkeeping
The laboratory assures the sampling record includes the sampling procedure used, any
deviations from the procedure,the date and time of sampling,the identification of the sampler,
environmental conditions (if relevant),and the sampling location.
5.8 Sample Management &Handling
5.8.1 Procedures
The laboratory's procedures for sample management and handling are outlined in laboratory
SOP ENV-SOP-GBAY-0006,Sample Management and Review of Analytical Requests.
The procedures in these SOPs are established to maintain the safe handling and integrity of
samples from transport, storage,to disposal and during all processing steps to maintain client
confidentiality,and to protect the interests of PAS and its customers.
5.8.1.1 Chain of Custody
All samples received by the laboratory must be accompanied with a Chain of Custody
(COC) record. The COC provides information about the samples collected and
submitted for testing and documents the possession of samples from time of
collection to receipt by the laboratory.
The COC record must minimally include the following information:
• Client name,address,phone number;
• Project Reference;
Page 58 of 100

■ Client Sample Identification(Client ID);
• Date,Time,and Location of Sampling;
■ Sampler's Name or Initials;
• Matrix;
• Type of container,and total number collected for each sample;
• Preservatives;
• Analyses Requested;
• Mode of collection;
• Any special instructions;and
• The date and time and signature of each sample transfer from time of collection
to receipt in the laboratory. When the COC is transported inside the cooler,
independent couriers do not sign the COC, the shipping manifests and/or air
bills are the records of possession during transport. The shipping manifest must
be retained as part of the COC record and included in the test report when
required (See Section 5.10.3).
A complete and legible COC is required. If the laboratory observes that the COC is
incomplete or illegible,the client is contacted for resolution. The COC must be filled
out in indelible ink. Personnel correct errors by drawing a single line through the
initial entry so the entry is not obscured, entering the correct information, and
initialing,and dating the change.
5.8.1.2 Legal Chain of Custody
Legal chain of custody is a chain of custody protocol used for evidentiary or legal
purposes. The protocol is followed by the laboratory when requested by customer or
where mandated by a regulatory program.
Legal chain of custody(COC) protocol establishes an intact,continuous record of the
physical possession*, storage, and disposal of "samples" which includes sample
aliquots,and sample extracts/digestates/distillates.
Legal COC records account for all time periods associated with the samples and
identifies all individuals who physically handled individual samples.Legal COC begins
at the point established by legal authority, which is usually at the time the sample
containers are provided by the laboratory for sample collection or when sample
collection begins.
*A sample is in someone's custody if:
• It is in one's physical possession;
• It is in one's view after being in one's physical possession;
• It has been in one's physical possession and then locked or sealed so that no one
can tamper with it;and/or

■ It is kept in a secure area,restricted to authorized personnel only.
Refer to laboratory SOP ENV-SOP-GBAY-0006, Sample Management and Review of
Analytical Requests for more information.
5.8.2 Unique Identification
Each sample is assigned a unique identification number by the laboratory (Lab ID) after the
sample has been checked and accepted by the laboratory in accordance with the laboratory's
sample acceptance policy (See 5.8.3). The Lab ID is affixed to the sample container using a
durable label.
The unique identification of samples also applies to subsamples,and prepared samples,such
as extracts,digestates, etc.
The lab ID is linked to the field ID (client ID) in the laboratory's record. Both IDs are linked
to the testing activities performed on the sample and the documentation records of the test.
Also see 5.8.4.
5.8.3 Sample Receipt Checks and Sample Acceptance Policy
The laboratory checks the condition and integrity of samples on receipt and compares the
labels on the sample containers to the COC record. Any problem or discrepancy is recorded.
If the problem impacts the suitability of the sample for analysis or if the documentation is
incomplete,the client is notified for resolution.Decisions and instructions from the client are
maintained in the project record.
5.8.3.1 Sample Receipt Checks
The following checks are performed:
■ Verification that the COC is complete and legible.
• Verification that each sample's container label includes the client sample ID,the
date and time of collection and the preservative in indelible ink.
■ The container type and preservative are appropriate for each test requested.
• Adequate volume is received for each test requested.
• Visual inspection for damage or evidence of tampering.
• Visual inspection for presence of headspace in VOA vials. (VOA = volatile
organic analysis).
• Thermal Preservation:Generally,for chemical testing methods for which thermal
preservation is required,temperature on receipt is acceptable if the measurement
is above freezing but <6°C. The requirements for thermal preservation vary
based on test method or by regulatory program. For example, for microbiology,
temperature on receipt is acceptable if the measurement is <10°C. Refer to the
laboratory's SOP for sample receipt for specific requirements. For samples that
are hand-delivered to the laboratory immediately after sample collection, there
must be evidence that the chilling process began immediately after sample

collection and prior to delivery of the samples to the laboratory or service center,
such as arrival of the samples on ice.
• Chemical Preservation
■ Holding Time: Sample receiving personnel are trained to recognize tests where
the holding time is 48 hours or less and to expedite the log-in of these samples.
Except for tests with immediate holding times (15 minutes from time of
collection or less), when samples are received out of hold, the laboratory will
notify the client and request instruction.If the decision is made to proceed with
analysis,the final test report will include notation of this instruction.
5.8.3.2 Sample Acceptance Policy
The laboratory maintains a sample acceptance policy in accordance with regulatory
guidelines to clearly establish the circumstances in which sample receipt is accepted
or rejected.
When receipt does not meet criteria for any one of these conditions, the laboratory
must document the noncompliance, contact the customer, and either reject the
samples or fully document any decisions to proceed with testing.In accordance with
regulatory specifications, test results associated with receipt conditions that do not
meet criteria are qualified in the final test report.
All samples received must meet each of the following criteria:
• Be listed on a complete and legible COC;
• Be received in properly labeled sample containers;
• Be received in appropriate containers that identify preservative;
• The COC must include the date and time of collection for each sample;
• The COC must include the test method requested for each sample;
• Be in appropriate sample containers with clear documentation of the
preservatives used;
• Be received within holding time.Any samples received beyond the holding time
will not be processed without prior customer approval;
• Have sufficient sample volume to proceed with the analytical testing. If
insufficient sample volume is received,analysis will not proceed without customer
approval;and
• Be received within appropriate temperature ranges unless program requirements
or customer contractual obligations mandate otherwise.The cooler temperature
is recorded directly on the COC.
Samples that are delivered to the laboratory immediately after collection are
considered acceptable if there is evidence that the chilling process has been
started. For example, by the arrival of the samples on ice. If samples arrive that
Page 61 of 100

are not compliant with these temperature requirements, the customer will be
notified. The analysis will NOT proceed unless otherwise directed by the
customer. If less than 72 hours remain in the hold time for the analysis, the
analysis may be started while the customer is contacted to avoid missing the hold
time. Data associated with any deviations from the above sample acceptance
policy requirements will be appropriately qualified.
5.8.4 Sample Control and Tracking
The samples are controlled and tracked using the Laboratory Information Management
System (LIMS). The LIMS stores information about the samples and project. The process of
enteringinformation into the LIMS is called log-in and these procedures are described in
g
laboratory SOP ENV-SOP-GBAY-0006, Sample Management and Review of Analytical Requests.
After log-in, a label is generated and affixed to each sample container. Information on this
label, such as the lab ID,links the sample container to the information in LIMS.
At a minimum,the following information is entered during log-in:
• Client Name and Contact Information;
• The laboratory ID linked to the client ID;
• Date and time of sample collection;
• Date and time of sample receipt;
• Matrix;and
• Tests Requested.
5.8.5 Sample Storage,Handling, and Disposal
The laboratory procedures for sample storage,handling and disposal are detailed in laboratory
SOPs ENV-SOP-GBAY-0006, Sample Management and Review of Analytical Requests and ENV-
SOP-GBAY-0126, Waste Handling and Management(most current revision(s) or replacement(s).
5.8.5.1 Sample Storage
The samples are stored according to method and regulatory requirements as per test
method SOPs. Samples are stored away from all standards, reagents, or other
potential sources of contamination and stored in a manner that prevents cross
contamination.Volatile samples are stored separately from other samples.All sample
fractions, extracts,leachates,and other sample preparation products are stored in the
same manner as actual samples or as specified by the analytical method.
Refrigerated storage areas are maintained at 5_6°C (but not frozen) and freezer storage
areas are maintained at <-10°C, unless otherwise required per method or program.
The temperature of each storage area is checked and documented at least once for
each day of use.If the temperature falls outside the acceptable limits, then corrective
actions are taken and appropriately documented.
The laboratory is operated under controlled access protocols to ensure sample and
data integrity.Visitors must register at the front desk and be properly escorted while
on-site. Samples are taken to the appropriate storage location immediately after
sample receipt and log-in procedures are completed. All sample storage areas have
Page 62 of 100

limited access. Samples are removed from storage areas by designated personnel and
returned to the storage areas as soon as possible after the required sample quantity
has been taken.
5.8.5.2 Sample Retention and Disposal
The procedures used by the laboratory for sample retention and disposal are detailed
in laboratory SOP ENV-SOP-GBAY-0126, Waste Handling and Management.
In general,unused sample volume and prepared samples such as extracts,digestates,
distillates and leachates (samples) are retained by the laboratory for the timeframe
necessary to protect the interests of the laboratory and the customer.
Samples may be stored at ambient temperature when all analyses are complete, the
hold time is expired, the report has been delivered, and/or when allowed by the
customer or program. Samples requiring storage beyond the minimum sample
retention time due to special requests or contractual obligations may be stored at
ambient temperature unless the laboratory has a capacity and their presence does not
compromise the integrity of other samples.
After this period expires, non-hazardous samples are properly disposed of as non-
hazardous waste. The preferred method for disposition of hazardous samples is to
return the excess sample to the customer.
5.9 Assuring the Quality of Test Results
5.9.1 Quality Control(QC) Procedures
The laboratory monitors the validity and reliability of test results using quality control (QC)
samples that are prepared and analyzed concurrently with field samples in the same manner as
field samples. QC results are always associated to and reported with the field samples they
were prepared and analyzed with from the same preparation or analytical batch. See the
glossary for definition of preparation and analytical batch.
The results of QC performed during the testing process are used by the laboratory to assure
the results of analysis are consistent, comparable,accurate, and/or precise within a specified
limit. When the results are not within acceptance criteria or expectations for method
performance, correction and corrective action(s) are taken. These actions may include
retesting or reporting of data with qualification to alert the end user of the situation.
Other QC measures performed include the use of certified reference materials (see 5.6.4),
participation in interlaboratory proficiency testing(see 5.9.1.2),verification that formulae used
for reduction of data and calculation of results is accurate (see 5.9.3),on-going monitoring of
environmental conditions that could impact test results (see 5.3.2), and evaluation and
verification of method selectivity and sensitivity(see 5.4.5).
QC results are also used by the laboratory to monitor performance statistical trends over time
and to establish acceptance criteria when no method or regulatory criteria exist.(See 5.9.1.1.9)).
5.9.1.1 Essential QC
Although the general principles of QC for the testing process apply to all testing,the
QC protocol used for each test depends on the type of test performed.
Page 63 of 100

aceAnalytical
LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
QC protocol used by the laboratory to monitor the validity of the test are specified in
test method SOPs. The SOP includes QC type, frequency, acceptance criteria,
corrective actions,and procedures for reporting of nonconforming work.
These requirements in the SOP conform to the reference method and any applicable
regulations or certification and accreditation program requirement for which results
of the test are used. When a project requires more stringent QC protocol than
specified in the SOP,project specification is followed. When the project requires less
stringent QC protocol, the project specification may be followed as an authorized
departure from the SOP when the project specifications meet the requirements in the
mandated method and any regulatory compliance requirements for which the data
will be used.
The following are examples of essential QC for Chemistry:
5.9.1.1.1 Second Source Standard (ICV/QCS)
The second source standard is a standard obtained from a different
vendor than the vendor of the standards used for calibration or it
may be from a different lot from the same vendor when there are
limited vendors that offer the material. It is a positive control used
to verify the accuracy of a new calibration relative to the purity of
the standards used for calibration. This check is referred to in test
method and quality system standards as the initial calibration
verification (ICV) or quality control sample (QCS). The second
source standard is analyzed immediately after the calibration and
before analysis of any samples. When the ICV is not within
acceptance criteria,a problem with the purity or preparation of the
standards may be indicated.
5.9.1.1.2 Continuing Calibration Verification(CCV)
CCV results are used to determine if the analytical response has
significantly changed since initial calibration. If the response of the
CCV is within criteria, the calibration is considered valid. If not,
there is a problem that requires further investigation. Actions taken
are technology and method specific.
5.9.1.1.3 Method Blank(MB) / Other Blanks
A method blank is a negative control used to assess for
contamination during the prep/analysis process. The MB consists
of a clean matrix, similar to the associated samples that is known to
be free of analytes of interest. The MB, unless otherwise specified
by the test method, is processed with and carried through all
preparation and analytical steps as the associated samples.
In general, contamination is suspected when the target analyte is
detected in the MB above the reporting limit. Some programs may
require evaluation of the MB to 1/2 the reporting limit or the
detection limit. When contamination is evident, the source is
investigated, and corrections are taken to reduce or eliminate it.

Analytical results associated with MB that does not meet criteria are
qualified in the final test report.
Other types of blanks that serve as negative controls in the process
may include:
■ Trip Blanks (VOA)
■ Storage Blanks
■ Equipment Blanks
■ Field Blanks
• Calibration Blanks
• Cleanup Blanks
• Instrument Blanks
5. .1.1. Laboratory Control Sample (LCS)
The LCS is positive control used to measure the accuracy of process
in a blank matrix. The LCS is spiked by the laboratory with a known
amount of analyte. The spike is a standard solution that is pre-made
or prepared from a certified reference standard.Like the MB,unless
otherwise specified in the test method, the LCS is processed with
and carried through all preparation and analytical steps as the
associated samples.
When the percent recovery(%R) of the LCS is within the established
control limit, sufficient accuracy has been achieved. If not, the
source of the problem is investigated and corrected, and the
procedure may be repeated. Analytical results associated with LCS
that does not meet criteria are qualified in the final test report.
5. .1.1. Matrix Spike (MS) and Matrix Spike Duplicate (MSD)
Matrix spikes measure the effect the sample matrix has on precision
and accuracy of the determinative test method. The MS and MSD
are replicates of a client sample that is spiked with known amount of
target analyte. •
Due to the heterogeneity of matrices even of the same general matrix
type, matrix spike results mostly provide information on the effect
of the matrix to the client whose sample was used and on samples
of the same matrix from the same sampling site. Therefore, MS
should be client-specific when the impact of matrix on accuracy and
precision is a project data quality objective. When there is not a
client-specified MS for any sample in the batch, the laboratory
randomly selects a sample from the batch; the sample selected at
random is called a"batch"matrix spike.
The MS/MSD results for percent recovery and relative percent
difference are checked against control limits. Because the
performance of matrix spikes is matrix-dependent, the result of
matrix spikes is not used to determine the acceptability of the test.

5.9.1.1.6 Sample Duplicate (SD)
A sample duplicate is a second replicate of sample that is prepared
and analyzed in the laboratory along another replicate. The SD is
used to measure precision.
The relative percent difference between replicates are evaluated
against the method or laboratory derived criteria for relative percent
difference (RPD), when this criterion is applicable. If RPD is not
met,associated test results are reported with qualification.
5.9.1.1.7 Surrogates
Surrogates are compounds that mimic the chemistry of target
analytes but are not expected to occur naturally in real world
samples. Surrogates are added to each sample and matrix QC
samples (MS, MSD, SD) at known concentration to measure the
impact of the matrix on the accuracy of method performance.
Surrogates are also added to the positive and negative control
samples (MB, LCS) to evaluate performance in a clean matrix, and
included in the calibration standards and calibration check standards.
The percent recovery of surrogates is evaluated against method-
specified limits or statistically derived in-house limits. Project-
specific limits and/or program-specific limits are used when
required. Results with surrogate recovery out of limits in samples
are reported with qualification. Samples with surrogate failures can
also be re-extracted and/or re-analyzed to confirm that the out-of-
control value was caused by the matrix of the sample and not by
some other systematic error.
5.9.1.1.8 Internal Standards
Internal Standards are compounds not expected to occur naturally
in field samples. They are added to every standard and sample at a
known concentration prior to analysis for the purpose of adjusting
the response factor used in quantifying target analytes. The
laboratory follows specific guidelines for the treatment of internal
standard recoveries and further information can be found in the
applicable laboratory SOP.
5.9.1.1.9 QC Acceptance Criteria and Control Limits
The QC acceptance criteria are specified in test method SOPs. The
criteria in the SOP are based on the requirements in the published
test method or regulatory program. When there are no established
acceptance criteria, the laboratory develops acceptance criteria in
accordance with recognized industry standards.
Some methods and programs require the laboratory to establish
control limits for LCS, MS/MSD, and surrogate evaluation using
historical data. Laboratory developed limits are referred to as "in-

house" control limits. In-house control limits represent ± 3
Standard Deviations (99% confidence level) from the average
recovery of at least 20 data points generated using the same
preparation and analytical procedure in a similar matrix.
See laboratory SOP ENV-SOP-GBAY-0116, Control Charting and
Trend Analysis for more information about the procedures used to
establish in-house control limits.
5.9.1.2 Proficiency Testing(PT)
The laboratory participates in interlaboratory proficiency testing (PT) studies to
measure performance of the test method and to identify or solve analytical problems.
PT samples measure laboratory performance through the analysis of unknown
samples provided by an external source.
The PT samples are obtained from accredited proficiency testing providers (PTP) and
handled as field samples which means they are included in the laboratory's normal
analytical processes and do not receive extraordinary attention due to their nature.
The laboratory does not share PT samples with other laboratories, does not
communicate with other laboratories regarding current PT sample results during the
duration of the study, and does not attempt to obtain the assigned value of any PT
sample from the PT provider.
The laboratory investigates and implements corrective action whenever PT results are
scored unacceptable by the PT provider.
The frequency of PT participation is based on the certification and accreditation
requirements held by the laboratory.
5.9.2 QC Corrective Action
When the results of QC are not within acceptance criteria or expectations for method
performance, correction and corrective action(s) are taken per the specifications in the test
method SOP. These actions may include retesting or reporting of data with qualification to
alert the end user of the situation.
5.9.3 Data Review
The laboratory uses a tiered system for data review. The tiered process provides sequential
checks to verify data transfer is complete; manual calculations, if performed, are correct,
manual integrations are appropriate and documented, calibration and QC requirements are
met,appropriate corrective action was taken when required,test results are properly qualified,
process and test method SOPs were followed,project specific requirements were met,when
applicable,and the test report is complete.
The sequential process includes three tiers referred to as primary review, secondary review,
and administrative/completeness review.
Detailed procedures for the data review process are described in laboratory SOP ENV-SOP-
GBAY-0120,Data Review and Final ReportProcess. The general expectations for the tiered review
process are described in the following sections:

exceptions are properly qualified
• Work is consistent with SOPs and any other relevant instructional document such
as SWI,program requirements,or project QAPP.
5.9.3.2 Secondary Review
Secondary review is performed by a qualified peer or supervisor. Secondary review is
essentially a repeat of the checks performed during primary review by another person.
In addition to the checks of primary review, secondary review includes
chromatography review to check the accuracy of quantitative analyte identification.
5.9.3.3 Completeness Review
Completeness review is an administrative review performed prior to release of the test
report to the customer. Completeness review verifies that the final test report is
complete and meets project specification. This review also assures that information
necessary for the client's interpretation of results are explained in the case narrative
or footnoted in the test report.
5.9.3.4 Data Audits
In addition to the 3-tier data review process, test reports may be audited by local
quality personnel to verify compliance with SOPs and to check for data integrity,
technical accuracy,and regulatory compliance. These audits are not usually done prior
to issuance of the test report to the customer. The reports chosen for the data audits
are selected at random.
If any problems with the data or test results are found during the data audit,the impact
of the nonconforming work is evaluated using the process described in Section 4.9.
Also see Section 4.14 for internal audits.
5.9.4 Calibration Certificates
The laboratory does not perform calibration activities for its customers and calibration
certificates are not offered or issued.

5.10 Reporting
5.10.1 General Requirements
The laboratory reports results of testing in a way that assures the results are clear, and
unambiguous.All data and results are reviewed prior to reporting to assure the results reported
are accurate and complete.
Test results are summarized in test reports that include all information necessary for the
customer's interpretation of the test results. Additional information necessary to clarify the
data or disclose nonconformance, exceptions,or deviations that occurred during the analytical
process are also reported to the customer in the test report.
The specifications for test reports and EDD are established between the laboratory and the
customer at the time the request
est for analytical services is initiated. The rep
ort y specifications
include the test report format, protocol for the reporting limit (RL), conventions for the
reporting of results less than the limit of quantitation (LOQ), and specification for the use of
project or program specific data qualifiers. Information about review of analytical service
requests is provided in Section 4.4.
5.10.2 Test Reports: Required Items
Test Reports are prepared by the laboratory at the end of the testing process. The format of
the report depends on the level of reporting requested by the customer. The laboratory offers
a variety of standardized test report formats and can provide custom test report formats,when
necessary.
The level of detail required in the test report depends on the customer's needs for data
verification, validation, and usability assessments that occur after the laboratory releases the
test report to the customer. The test report formats offered by the laboratory provide gradient
levels of detail to meet the unique needs of each customer. The laboratory project manager
helps the customer select the test report format that best meets their needs. When a specific
report format or protocol is required for a regulatory or program compliance,the laboratory
project manager must ensure the test report selected meets those requirements.
Every test report issued by the laboratory includes each of the following items:
a) Title
b) Name and phone number of a point of contact from the laboratory issuing the report.
c) Name and address of the laboratory where testing was performed. When testing is done
at multiple locations within network (IRWO), the report must clearly identify which
network laboratory performed each test and must include the physical address of each
laboratory.
d) Unique identification of the test report and an identifier on each page of the report to link
each page to the test report and clear identification of the end of the report.

LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
8.0 ADDENDUM: PROGRAM REQUIREMENTS
Program specific information provided in this addendum supplements the main body of this manual.
Each subsection is stand-alone, meaning the requirements for the quality management system in each
subsection only apply to the program referenced. Additionally,only program requirements for the quality
management system that are more stringent than the content of the main body of the manual are included.
8.1 DoD/DoE
PAS-Green Bay maintains accreditation for DoD/DoE Environmental Laboratory Approval
Program(ELAP)
This addendum outlines additional policies and processes established by this laboratory to maintain
compliance with DoD/DOE program specific requirements as outlined in the DoD/DoE
Consolidated Quality Systems Manual (QSM) for Environmental Laboratories. The QSM
incorporates ISO/IEC 17025 and the TNI Standard and includes additional program-specific
requirements for laboratories that perform analytical testing services for DoD and DoE and which
must be followed for DoD / DoE projects.
Section 4.2.5: Supporting Documents
Technical SOPs used for DoD/DoE testing must also include instructions for equipment and
instrument maintenance, computer software/hardware,and troubleshooting.
The review frequency for technical SOPs used for DoD/DoE testing is annual, instead of every 2
years.
Section 4.4: Review of Analytical Service Requests
If the DoD/DoE customer requests a statement of conformity, the standard used for the decision
rule must be communicated to and agreed on with the customer and identified in the final test report.
Laboratory requests to deviate from the requirements specified in the DoD/DoE QSM must be
requested on a project-basis and include technical justifications for the deviation. These requests are
submitted to and approved by the DoD/DoE project chemist or contractor, however named, in
addition to the PAS client.
For DoD / DoE projects, will also seek clarification from the customer when the customer has
requested an incorrect, obsolete or improper method for the intended use of data; the laboratory
needs to depart from its test method SOP in order to meet project-specific data quality objectives;
information in project planning documents is missing or is unclear,
Section 4.5: Subcontracting
In addition to written client approval of any subcontractor for testing,the customer is notified of the
laboratory's intent to use a subcontractor for any management system element (such as data review,
data processing, project management or IT support) and consent for subcontracting is obtained
approved in writing by the DoD/DoE customer and record of consent kept in the project record.
Section 4.6: Purchasing and Supplies
The laboratory procedure for records of receipt of materials and supplies used in testing also include
a specification to record the date opened(DoE only).

LABORATORY QUALITY MANUAL
Pace Analytical Services,LLC
COPYRIGHT©2021-2023 Pace Analytical Services,LLC.
Section 4.9.3: Nonconforming Work
The laboratory's procedure for client notification includes the 15-business day DoD/DOE timeframe
for notification of the problem and the 30-business day timeframe for submission of the corrective
action plan or corrective actions taken.This procedure also includes the DoD/DoE requirement for
AB notification of discovery.
Section 4.13: Control of Records
Technical Records: The laboratory's procedure for logbooks includes measures to prevent the
removal of or addition of pages to the logbook(applies to both hardcopy and electronic). Hardcopy
logbooks are version controlled, pre-numbered and bound. Initials and entries and are signed or
initialed and dated by the person making the entry and the entry is made at the time the activity is
performed and in chronological order. Each page of the logbook must be closed by the last person
making the entry on the page. Closure is recorded by the initial and date of the person making the
last entry.
Section 5.4.5.3.3: Limit of Detection
For DoD/DoE the LOD is an estimate of the minimum amount of an analyte that can be reliably
detected by an analytical process. For clarification, the LOD is the analyte concentration necessary
to distinguish its presence from its absence. The LOD may be used as the lowest concentration for
reliably reporting a non-detect(ND). The LOD is specific to each suite of analyte,matrix,and method
including sample preparation.
After each DL determination,the laboratory establishes the LOD by spiking a quality system matrix
at a concentration of least 2X but no greater than 4X the DL (i.e. 2X DL <_ LOD Spike <_ 4X DL).
The spike concentration establishes the LOD and the concentration at which the LOD is verified.
The LOD is established during method validation and after major changes to the analytical system or
procedure that affects sensitivity of analysis or how the procedure is performed.
An LOD study is not required for any component for which spiking solutions or quality control
samples are not available. Additionally,an LOD study is not required if the laboratory does not report
data below the LOQ.
The LOD must be verified on a quarterly basis. Each preparation method listed on the scope of
accreditation must have quarterly LOD verifications; however, verification of all possible
combinations of preparation and clean-up techniques is not required. Where LOD verifications are
not performed on all combinations, the LOD verification is based on the worst-case combination
(preparation method with all applicable cleanup steps).
The laboratory's procedure for LOD determination and verification is detailed in laboratory SOP
ENV-SOP-GBAY-0106 Determination of the LOD and LQQ (most recent revision or replacement).
Section 5.4.5.3.4: Limit of Quantitation
For DoD/DoE, the LOQ is established for each analyte-matrix-method combination, including
surrogates. When an LOD is determined or verified by the laboratory,the LOQ must be above the
LOD [DL<LOD<LOQ].
At a minimum,the LOQ must be verified quarterly;however,verification of all possible combinations
of preparation and clean-up techniques is not required. Where LOQ verifications are not performed

on all combinations,the LOQ verification on the worst-case combination (preparation method with
all applicable cleanup steps).
The laboratory's procedure for LOQ determination and verification is detailed in laboratory SOP
ENV-SOP-GBAY-0106 Determination of the LOD and LOQ (most recent revision or replacement).
Section 5.4.7: Control of Data
The laboratory will assure LIMS passwords are changed at least once per year.
An audit of the LIMS will be incorporated into the laboratory's annual internal audit schedule.
The laboratory will have procedures in place to notify DoD/DoE customers of changes to LIMS
software or hardware configurations that may impact the customer's integrity of electronic data
Section 5.9.1: Quality Control
For DoD/DoE,storage blanks are essential QC to monitor the storage of samples for volatile organic
analysis (VOA). The laboratory's SOP for storage of VOA samples must include a contamination
monitoring program based on the performance of storage blanks. (See QSM 5.3.3)
Section 5.8.5: Sample Disposal
For DoE projects, the record of disposal must also include how the sample was disposed and the
name of the person that performed the task.
Appendix E: Support Equipment Calibration
Mechanical Volumetric Pipette: In addition to the quarterly verification check, pipettes used for
DoD/DoE projects are checked daily before use using the same procedure and criteria specified for
the quarterly check.
Water Purification System: The performance of the water purification system is checked daily prior
to use in accordance with laboratory SOP ENV-SOP-GBAY-0127 Use and Maintenance of Water
Purification Systems(most recent revision or replacement).
Radiological Survey Equipment: The performance of the radiological survey equipment is checked
daily prior to use in accordance with laboratory SOP ENV-SOP-GBAY-0158 ECD Management(most
recent revision or replacement).
Additional: (DoE): Section 6.0 of the QSM outlines additional management system requirements
for the management of hazardous and radioactive materials management and health and safety
practices. The laboratory,if approved for DoE,will work with the PAS Health and Safety Director
to establish plans, policies and procedures that conform to these comprehensive specifications and
incorporate these documents into the quality management system.

1.0 SCOPE AND APPLICATION
This standard operating procedure (SOP) describes the laboratory procedure for the determination of
sub-ppb (dig/L) concentrations of a large number of elements in biota, aqueous, and solid extracts or
digests by inductively coupled plasma-mass spectrometry (ICPMS). When dissolved constituents
are required, samples must be filtered and acid-preserved prior to analysis. Dissolved samples are
typically acid digested prior to analysis. Acid digestion prior to centrifuging and analysis is required
for aqueous and solid samples for which total (acid-leachable) elements are required.

1.2 Applicable Matrices
1.2.1 This SOP is applicable to aqueous (dissolved, total, waste) samples.
1.2.2 This SOP is applicable to ASTM, SPLP, and TCLP samples.
1.2.3 This SOP is applicable to solid/soil samples.
1.2.4 This SOP is applicable to Biota (biological) samples.
1.3 Personnel: Use of this method is restricted to analysts who are knowledgeable in the recognition
and in the correction of spectral, chemical, and physical interferences in ICPMS.
2.0 SUMMARY OF METHOD
2.1 Prior to analysis, samples which require total ("acid-leachable") values must be digested using
appropriate sample preparation methods. A number of methods are recommended in SW846
and EPAsamplepreparation/digestion
200.8 for the of various matrices for tr
ace metals
analysis by ICPMS. Applicable analytes are listed in the Target Analyte List.
2.2 Methods 6020B/200.8 describe the multi-elemental determination of analytes by ICPMS. The
method measures ions produced by a radio frequency inductively coupled argon plasma.
Analyte species originating in a liquid are nebulized and the resulting aerosol transported by
argon gas into the plasma torch. The ions produced are entrained in the plasma gas and
introduced, by means of an interface, into a mass spectrometer. The ions produced in the
plasma are sorted according to their mass-to-charge ratios and quantified with a channel
electron multiplier. Interferences must be assessed, and valid corrections applied, or the data
must be flagged to indicate problems. Interference correction must include compensation for
background ions contributed by the plasma gas, reagents, and constituents of the sample
matrix as well as isobaric elemental corrections.
3.0 INTERFERENCES
3.1 Isobaric Elemental Interferences — Isobaric elemental interferences result when isotopes of
different elements have the same nominal mass-to-charge ratio and cannot be resolved with
the instruments spectrometer. One way to solve this problem is to measure a different isotope
for which there is no interference. Alternatively, one can monitor another isotope of the
element and subtract an appropriate amount from the element being analyzed, using known
isotope ratio information. Corrections for most of the common elemental interferences are
programmed into the software.
3.2 Isobaric Polyatomic Interferences — Isobaric polyatomic interferences result when ions containing
more than one atom have the same nominal mass-to-charge ratio as an analyte of interest and
cannot be resolved by the instrument's spectrometer. An example includes CIO+ (mass 51),
which interferes with V, and must be corrected by measuring CIO+ at mass 53. When possible,
an interference free isotope should be chosen for measurement.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

3.3 Physical interferences are associated with the sample nebulization and transport processes as
well as with ion-transmission efficiencies. Nebulization and transport processes can be
affected if a matrix component causes a change in surface tension or viscosity. Changes in
matrix composition can cause significant signal suppression or enhancement. Dissolved solids
can deposit on then nebuli
zer zer tip of a pneumatic nebulizer and on the interface skimmers
(reducing the orifice size and the instrument performance). Total solid levels below 0.2% (2,000
mg/L) have been currently recommended to minimize solid deposition. An internal standard
can be used to correct for physical interferences if it is carefully matched to the analyte so that
the two elements are similarly affected by matrix changes.
3.4 Memory interferences can occur when there are large concentration differences between
samples or standards which are analyzed sequentially. Sample deposition on the sampler and
skimmer cones, spray chamber design, and the type of nebulizer affects the extent of the
memory interferences which are observed. The rinse period between samples must be long
enough to eliminate significant memory interference.
3.5 It is important to note that matrix matching acid concentrations and compositions between
standards, blanks, and samples is required and cannot be ignored.
3.6 Chromic acid should never be used to clean any container used in ICPMS analysis.
3.7 Borosilicate glass in sample containers can lead to interference of Boron concentrations in
samples. This is also true of volumetric flasks, thus when dilution in the flask is complete the
standards must be removed as soon as possible from the dilution container and placed into a
clean plastic container.
4.0 DEFINITIONS
Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions.
5.0 HEALTH AND SAFETY
The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully
established. Each chemical should be regarded as a potential health hazard and exposure to these
compounds should be as low as reasonably achievable.
The laboratory maintains documentation of hazard assessments and OSHA regulations regarding
the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous
chemicals are available to all personnel. Employees must abide by the health, safety and
environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical
Hygiene/Safety Manual.
Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be
worn in designated areas and while handling samples and chemical materials to protect against
physical contact with samples that contain potentially hazardous chemicals and exposure to
chemical materials used in the procedure.

Concentrated corrosives present additional hazards and are damaging to skin and mucus
membranes. Use these acids in a fume hood whenever possible with additional PPE designed for
handing these materials. If eye or skin contact occurs, flush with large volumes of water. When
working with acids, always add acid to water to prevent violent reactions. Any processes that emit
large volumes of solvents (evaporation/concentration processes) must be in a hood or apparatus that
prevents employee exposure.
Contact your supervisor or local HSE coordinator with questions or concerns regarding safety
protocol or safe handling procedures for this procedure.
6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE
Requirements for container type, preservation, and field quality control (QC) for the common list of
test methods offered by Pace are included in the laboratory's quality manual.
Samples should be collected in accordance with a sampling plan and procedures appropriate to
achieve the regulatory, scientific, and data quality objectives for the project.
The laboratory will provide containers for the collection of samples upon client request for analytical
services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle
Preparation (most recent version or replacement).
6.1 All sample containers must be HDPE, glass, or Teflon. The containers are purchased pre-cleaned
and documented to be contaminant free. Where applicable, the bottle ware is demonstrated to
be fee of target analytes. When bottle ware not originating from the lab is used, the data may
be qualified with either one or both of the following data qualifiers:
6.1.1 Sample field preservation does not meet EPA or method recommendations for this
analysis.
6.1.2 Sample container did not meet EPA or method requirements.
6.2 Aqueous Samples
6.2.1 Dissolved samples must be filtered through a 0.45-pm pore diameter membrane filter at the
time of collection or as soon after as practically possible. The laboratory can perform the
filtration if the step was not performed in the field. The filtrate is then preserved to a pH<2
with nitric acid, acid not to exceed 2% of the container capacity.
6.2.2 Total samples are preserved to a pH<2 with nitric acid, acid not to exceed 2% of the
container capacity.
Note: Aqueous samples that react violently to the addition of acid maybe collected without
chemical preservation with proper variances approved by the regulatory authority. The
responsibility of requesting this variance lies with the sample collector.
Note: Samples may be preserved in the lab. The samples may not be processed until 24
hours after preservation with a pH test of <2, unless otherwise noted on the data. Samples
that do not attain a pH<2 or samples that are filtered in the lab must be flagged with P4.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Chemical preservation is checked and recorded at time of receipt or prior to sample preparation.
Shipments of soil and water samples to the laboratory require thermal preservation in the form of
cubed, block or dry ice. At the time of laboratory receipt, proper thermal preservation is checked by
measuring the temperature of melt water or when provided the temperature blank. The Pace
Analytical acceptable temperature range is 0 to 6°C (or 5.-10 for dry ice for biota samples). All QAPjP
and regulatory authority requirements become priority over this requirement.
After receipt, aqueous samples are stored at room temperature, solid samples are stored at 0 - 6°C,
and biota samples are stored at -10°C or less until sample preparation. Prepared samples
(digestates)are stored at room temperature until sample analysis.
After analysis, unless otherwise specified in the analytical services contract, samples are retained for
21 days from date of final report and then disposed of in accordance with Federal, State, and Local
regulations.

8.0 REAGENTS AND STANDARDS
8.1 Standards are used in the tuning of the instrument through the calibration, calibration verification,
sample analysis, and continuing calibration verification. Standard solutions include: instrument
tuning solutions, calibration and calibration check standards, ICSA/AB, internal standards, low
level check standards (LLC, CRI, or CRDL), and spike standards. Please see Table 8.7 for a
list of working standards. Table 8.6 lists the directions to making intermediate standards
from the stock standards listed in Table 8.5.
8.1.1 Mass Spectrometer Tuning Solution: A solution containing elements representing all of the
mass regions of interest (for example, 10 pg/L of 23, 24, 25Mg and 206, 207, 208Pb) must be
prepared to verify that the mass resolution and mass calibration of the instrument are within
the required specifications. This solution is also used to verify that the instrument has
reached thermal stability.
8.1.2 Cross Calibration Solution (X Cal): contains 50 ppb of all method analyte elements (with the
exception of Li, at 100ppb). This solution is used to calculate the concentration when the
detector changes from pulse mode to analog mode. This enables a large linear range
while protecting the detector.
8.1.3 Calibration Standards: These are an increasing gradient of concentration for the analytes of
interest. These can be made in the laboratory or purchased from commercial suppliers.
8.1.4 Linear Range (LR): These standards may be a mix or single element standard used to
verify the upper limit of the instrument's working range. 6020B requires that the upper limit
of the range be verified every calibration. If the LDR is not verified above the high point of
the calibration, it defaults to the high point of the calibration. This procedure will be
followed for all sample analysis.
8.1.5 Initial Calibration Verification (ICV): The quality control standard is the initial calibration
verification solution (ICV), which must be prepared in the same acid matrix as the
calibration standards. This solution must be an independent standard at approximately half
(or less than) of the concentration of the high standard used for instrument calibration. An
independent standard is defined as a standard composed of the analytes from a source
different from those used in the standards for instrument calibration.
8.1.6 Reporting Limit Verification Standard (RLVS / CRDL): With every Initial Calibration, a
standard corresponding to the Pace reporting limit (PRL), or lower, must also be analyzed
and meet established acceptance criteria. The RLVS is analyzed prior to any samples
being analyzed. It is also analyzed at the end of the analytical sequence when following
6020B quality control samples (LOD sets and DOC sets) or by client request. Additional
RLVSs may be analyzed throughout the analytical sequence at the analyst's discretion.
These standards are the first calibration point for the analytes of interest. The analysis of
this standard demonstrates the instruments ability to report down to the reporting limit with
known accuracy.
8.1.7 ICS LDR 1, 2, and 3: These standards are analyzed to establish the linear range with each
calibration. The set is essentially all of the major cations in 3 separate standards since
combining all of them in one standard would cause problems with the internal standard
recoveries due to the total amount of dissolved solids present. It is known that the single
element Al and Ca standards contain a background of Sr above the first calibration point at

the concentrations used and is not a polyatomic interference that requires a correction
equation. The control limit for Sr in these 2 standards (LDR 1 & 2) is < RL above the mean
background concentration.
8.1.8 Interference Check Solutions (ICSA and ICSAB): The ICSA and ICSAB are prepared to
contain known concentrations of interfering elements that will demonstrate the magnitude
of interferences and provide an adequate test of any corrections. The ICSA and ICSAB are
analyzed prior to any samples. They are also analyzed at the end of the analytical
sequence by client request. Chloride in the ICS provides a means to evaluate software
corrections for chloride-related interferences such as 35CI 160 on 51V. Iron is used to
demonstrate adequate resolution of the spectrometer for the determination of manganese.
Molybdenum serves to indicate oxide effects on cadmium isotopes. The other components
are present to evaluate the ability of the measurement system to correct for various
polyatomic isobaric interferences. The ICS is used to verify that the interference levels are
corrected by the data system to within quality control limits. Table D provides a summary
of the ICS-A and ICS-AB solution concentrations used.
8.1.9 Continuing Calibration Verification (CCV): This standard is near (or less than)the midpoint
of the curve and used to verify that the instrument is still in calibration. This standard is
from the same source as the calibration standards.
8.2 Reagents: Please see Table 8.4 for a list of reagents.
8.2.1 All standards, reagents, and spiking solutions are kept at room temperature. Stock
standards and reagents can be used until they expire. Refer to the most recent version of
ENV-SOP-GBAY-00145 Laboratory Supply Procedures for stock standard and reagent
expiration rules. Intermediate and working standards are given a six-month expiration date.
However, the expiration date may not extend past the earliest expiration date of any stock
standard used to create the solution. The use of any standard or reagent will be terminated
if any contamination or problems arise prior to the expiration date.
8.3 Log-in of Standards, reagents, and spike solutions are logged as follows:
8.3.1 Stock standards have a copy of their certificate of analysis logged into the LIMS (Epic Pro).
Please see the SOP T-ALL-IT-010 (most recent revision or equivalent).

9.0 PROCEDURE
9.1 Calibration and Standardization: The instrument is calibrated daily at a minimum when
analyzing samples. High solids and complex matrices can and do result in more frequent
calibration.
9.1.1 Calibration Curve: Demonstration and documentation of acceptable initial calibration is
required before any samples are analyzed and is required periodically throughout sample
analysis as dictated by the results of the continuing calibration verification standards.
Calibration consists of a calibration blank and four or five non-zero standards (analyte
dependent) analyzed after a calibration blank. The ICPMS software creates a curve based
on this data which is linear regression using Absolute Standard Deviation weighting
inclusive of the calibration blank with a calculated intercept and uses the following equation:
Y=a(x)+b. In calculating x (concentration)from y (response)the b (intercept) is subtracted.
The b represents the intercept of the regression line. The correlation coefficient must be
4.998. If the correlation coefficient is not within criteria, the issue must be resolved, and
the instrument recalibrated with passing criteria prior to analyzing samples. To satisfy
6020B calibration criteria the following must be met. The calculated concentration for the
lowest calibration point used must have a recovery of+/-20% (i.e. a relative error of<_20%).
The calculated concentration midpoint calibration standard must have a recovery of+/-10%
(i.e. a relative error of 510%). The calculated concentration highpoint calibration standard
must have a recovery of+/-10% (i.e. a relative error of<_10%)for LDR in 6020B.
9.1.2 Calibration Levels: Please see Table Below for directions on making the calibration
standards and the calibration levels used in the calculations.

9.1.3 Internal Standards:
9.1.3.1 Internal standardization must be used in all analyses to correct for instrument
drift and physical interferences. For full mass range scans, a minimum of six
internal standards must be used. Procedures described in this SOP for general
applications detail the use of seven internal standards; 6Li, 45Sc-CCT, 45Sc-KED,
72Ge, 89Y, 115ln, 159Tb, and 209Bi. The interpolation between 2 internal standards

is done when a reported element mass is bracketed by two internal standards.

159Tb 209Bi Hg—Pb
209Bi U
9.1.3.2 Internal standards must be present in all samples, standards, and blanks at
identical levels. This is achieved by directly adding the internal standard stock
solution (100ppb in 3% HNO3) to all samples, standards, and blanks by on-line
addition prior to nebulization using a second channel of the peristaltic pump and
a mixing T-connector. The concentration of the internal standard should be
sufficiently high that good precision is obtained in the measurement of the
isotope used for data correction and to minimize the possibility of correction
errors if the internal standard is naturally present in the sample. A final
concentration at the nebulizer of approximately 50 ppb will result from the
addition of a 100 ppb solution.
9.1.3.3 Due to matrix interferences one or more of the internal standards may not be
suitable. It is up to the analyst to recognize and correct the problem by diluting
the sample(s) for reanalysis. This procedure may result in some analytes being
diluted below the PRL and must be appropriately flagged.
9.1.3.4 During the determination, the software uses the ratio of analyte and internal
standard intensities to adjust the final concentration values. Ratios are based on
the intensities in the sample vs. the calibration blank intensities.
9.1.3.5 An internal standard without Li must be used if Li is an analyte of interest. If Li is
to be used as an internal standard, and Li is an analyte of interest, an isotopically
enriched Li standard must be used such that the analyte can be differentiated
from the internal standard. (i.e. 6Li enriched internal standard to report 7Li in
samples.)
9.1.4 Interference Calculations: Interference equations are used to correct for isobaric elemental
and polyatomic interferences. All equations can be adjusted if necessary or added if the
analyst determines that any particular correction is insufficient or if an equation is over
correcting the data. The Equations Table below shows the recommended Elemental
Interference Equations.

1 -The equation may require periodic adjustment based on the KED add gas and tuning
parameters. The mean value in counts per second (cps)for the calibration blank MUST be
> 0 cps (ideally, all replicates should be > 0 cps). The normal operating range in cps is 0- 1
1000cps for the calibration blank and must be inspected by the analyst.
2-The ICSA/AB and the LCS sample are used in the evaluation of this equation. Ca is
affected by doubly charged strontium and can vary from day to day plasma conditions. The
ICSA&AB will not fully identify doubly charged conditions based on the ratio of Ca to Sr,
whereas the LCS sample for waters and soils have sufficiently large Sr concentrations
compared to Ca and will assist in identification of adjustment requirements for the Ca
interference equation.
3-Zirconium must be less than the previously established linear dynamic range (LDR) of
10,000 pg/L on instrument for proper correction of polyatomic and doubly charged
interferences.

9.2.3.4 The Xcal solution does not need to be run unless a deviation between the pulse
counting and analog counting methods is observed in the spectra. The analog
counting will appear to sit significantly above the pulse baseline in an observed
spectra from the scan acquisition and indicates that the cross calibration needs
to be performed. Also, an indication of when the Xcal needs to be reset is when
the calibration loses its linearity (this will likely occur first with High Resolution
Mineral elements like Na and K or high concentration elements like Fe. A
deviation can also be observed for the heavy elements TI, Pb, and U). Aspirate
the Xcal solution in Standard Mode, with both the sample delivery and internal
standard lines (so as to not dilute the Xcal solution).

9.2.3.4.1 Cross Calibration Only. This is done when the deviation between
the pulse and analog counting methods is observed (from spectra or
from linearity observations) and the minimum counts per second
listed in the tuning section are achievable. Run the Instrument
Calibration wizard in PlasmaLab when deviation of the analog
spectra is observed. The detector cross calibration is selected by
default in the wizard. This will reset the detector-gating plateau
such that the analog spectra (dashed line in the spectra) will sit
directly on top of the pulse baseline (solid line in the spectra).
9.2.3.4.2 Detector Setup and Cross Calibration. This is done when the
minimum counts per second listed in the tune section are not
achievable. Thus, the detector dynode value will be adjusted, and a
new cross calibration will be performed with the new detector
voltage setting. Launch the Instrument Calibration wizard in
PlasmaLab and select detector set up. The detector cross
calibration will be checked by default, also select the detector set up
portion in the wizard. The voltage applied to the detector will be set
first to achieve acceptable sensitivity followed by a detector cross
calibration with the new detector setting.
9.2.3.4.3 Dead Time Experiment: This experiment must be and is only
performed after a detector is replaced. The dead time experiment
will identify the delay or "dead time" associated with a particular
detector. The dead time is the delay between the pulse
measurement and analog measurement when the detector gate is
dropped. In the experiment a 1 ppb and 10ppb solution of Uranium
is run, and the ratios between 235U and 238U are calculated for both
concentrations. The values for the ratios are adjusted such that the
ratio values are as close to identical as possible and that value
(dead time in nanoseconds) is entered into PlasmaLab software via
the Advanced Page.
9.2.3.5 Tune Procedure Summary (Use this order of events, some adjustments may be
required after an auto tune). Save each passing configuration with the Mode
followed by the Date (e.g. Standard Mode, CCT Mode, and KED Mode
09052020). The tunes for passing performance reports are valid for 36 hours.
Introduce the internal standard and aspirate a new rinse blank for 5-10 minutes
to eliminate any carry-over into the calibration blank.

Directions to make up the standards can be found in Tables 8.6 and 8.7.
9.2.4.2 Build a sequence in the sequence table and apply the repeat run rules to insert
the CCV and CCB for every 10 unknowns. A typical sequence will consist of a
calibration blank and calibration points 0 through 5, followed by an ICV, ICB,
CRDL, ICSA, ICSAB, CCV, CCB and then batch samples and QC. The repeat
rules set above will insert a CCV, CCB combo every 10 analyses and at the end
of the sequence.
9.2.4.3 Ensure the RLVS / CRDL standard bracket the sample list for analysis by 6020B
for LOD and DOC analysis. The bracketing check may be by Client specific
criteria and refer to any applicable requirements if there is uncertainty.
9.2.4.4 When the sample list and QC checks have been verified for accuracy, queue the
experiment to the Technician Queue. Each experiment will require a unique
code (e.g. 0905220A, 0905220B, for 401CM2, and add _3 after the name for
401CM3, etc.).

can be found in Attachment II.
10.0 DATA ANALYSIS AND CALCULATIONS
10.1 The Plasma Lab software performs all calculations necessary to convert raw counts per second
data into quantitative concentration results.
10.2 Consideration should be given to the interference equations that are in the method. As a result
of changing tune parameters over time, the equations may require adjustment periodically to
ensure they are not overcompensating or under compensating for the polyatomic or isobaric
interferences. This is especially true of 52Cr and 51V as the CCT-KED tune can vary slightly from
day to day operation. This variation (primarily in the add gas for the collision cell) will change
the counts per second acquired for CI and CIO ions. This can make the counts per second in
the calibration blank for these isotopes artificially high or low (See Section 9.1.4). In the case
of Lead, quantitation is based on the sum of isotopes 206, 207, and 208 to compensate for any
variation in naturally occurring isotope ratios. This is accomplished through the use of the
interference correction equation for lead.

11.0 QUALITY CONTROL AND METHOD PERFORMANCE
11.1 Quality Control: There are three levels of quality control utilized in this SOP. They consist of
Method QC, Instrument QC, and Prep/Batch QC.
11.2 Method QC consists of the instrument detection limits, linear ranges, method detection limits,
the lower limit quantitation check, and demonstrations of capability. This QC must be
completed prior to analyzing any samples.
11.2.1 Instrument Detection limits (IDLs): IDLs in pg/L are estimated as the mean plus the
average of the standard deviations of the three runs on three non-consecutive days
from the analysis of a reagent blank solution with ten consecutive measurements per
day. Each measurement must be performed as though it were a separate analytical
sample (i.e., each measurement must be followed by a rinse and/or any other
procedure normally performed between the analysis of separate samples). IDLs
must be determined quarterly.
11.2.2 Linear Dynamic Ranges (LDR): The LDR for each element is determined by
analyzing a standard series ending at a concentration expected to be near the high
end of the instruments range. The result must be within ± 10% of the expected
concentration, or a lesser concentration tested until acceptable results are obtained.
This procedure is done with each new instrument to determine the LDR of a
particular model of Instrument and methodology. This is critical to the determination
of any doubly charged, polyatomic and memory interferences. Once established,
6020B methodology will be followed. For 6020B the LDR is verified for each
calibration. If the ICS solutions for the higher concentration elements does not
recover within the 90-110% acceptance range, the high point of the calibration sets
the high end of the instrument working range and is the highest reportable
concentration for that element. The 6020B criteria is more stringent than 200.8 and
will be followed for both methods.
11.2.3 Method Detection Limits (MDLs): Method detection limits, at a minimum, are
obtained by multiplying 3.143 by the standard deviation of seven spikes. The spikes
went through the digestion procedures and were spiked at a concentration suspected
to be within a factor of ten greater than the MDL. The most recent version of the
MDL SOP, S-ALL-Q-004, must be followed when determining MDLs. Note: The MDL
determined by the MDL study is the theoretical MDL. The MDL used for reporting
purposes may be higher than the theoretical MDL.
11.2.4 Lower Limit of Quantitation Check Standard (LLOQ): The LLOQ is a standard at the
reporting limit concentration that has gone through all the preparation procedures.
For the purposes of 6020B, the acceptance criteria is ± 35% for the LLOQ sample.
The Percent RSD for the acquired LLOQ replicates should be <_ 20%. It is analyzed
to establish the lower limit of quantitation, verified quarterly using the data from the
LOD studies collected throughout the year, and whenever new limits are established.
If an element repeatedly does not meet criteria at a certain level, it should be re-
evaluated to determine if that level is realistic.

11.3 Instrument QC: Prior to the analysis of samples, and in some cases during the analysis run,
the following quality control must be generated and within limits: Performance Report for each
mode of operation generated (up to 36 hours since previous or a nonconformance filed when
the window is exceeded), Internal Standards, ICS LDR (1,2,&3), Interference Correction
Solutions A and B (ICSA and ICSAB), Initial Calibration Verification (ICV), Continuing
Calibration Verification (CCV), RLVS / CRDL standards, and Initial and Continuing Calibration
Blanks (ICB and CCB).
11.3.1 The intensities of all internal standards must be monitored for every analysis. When the
intensity of any required internal standard fails to fall between 60 and 125 percent of the
intensity of that internal standard in the blank of the calibration, one of the following
procedures is followed'. The sample is diluted appropriately and reanalyzed with the
addition of appropriate amounts of internal standards. This procedure must be repeated
until the required internal standard intensities fall within the prescribed window. If
significant deviation cannot be overcome by dilution of the sample in the same analytical
run, then recalibration is required. Sudden increases in internal standard recoveries of 10
or more percent may also indicate that dilutions are necessary. The presence of high
levels of dissolved solids in samples can result in instrument drift. A sequence with high
solids samples will have recoveries drift down. Should the internal standards drift outside
of the acceptance range; these samples will need to be re-analyzed at a dilution. If a
subsequent batch is clean (samples with low dissolved solids present) the instrument may
see an increase in signal and internal standard recovery. Unless the internal standards are
actually present in the samples, these can be re-analyzed at the same dilution after a
passing recalibration. 16020B allows for the lower limit of the internal standard recovery to
be set at 30%.
11.3.2 The ICSA, ICSAB, and ICS LDR solutions are used to verify the magnitude of elemental
and molecular-ion isobaric interferences and the adequacy of any corrections. They are
analyzed after the CRDL, prior to the analysis of any samples. For 200.8, additional ICSA
and ICSABs are not analyzed, as sequences do not reach 12 or more hours in duration.
By client request, the ICSA and ICSAB will be analyzed at the end of the analytical
sequence. The analyst should be aware that precipitation from solution AB may occur with
some elements, specifically silver. The control limits for the elements in the ICSA and
ICSAB solutions is 80 to 120% for 200.8 and those elements not being used for linear
range purposes. For 6020B the recovery of the elements with concentrations to establish
the linear range is 90-110% (specifically for Ti and Mo). Elements that are not spiked in the
ICSA, must have a measurement lower than the LOQ. If an element of interest does not
meet these limits, then the problem must be corrected, the instrument recalibrated, and the
run reanalyzed.
11.3.3 The ICV is analyzed to check the accuracy of the curve. It must be evaluated after each
calibration and before any samples are analyzed. The ICV should be at or near (or lower
than) the midpoint of the calibration curve, derived from a source independent of the
calibration standards, and must quantitate within ± 10% of the expected value. If these
limits are not met for an element of interest, the problem must be corrected, the instrument
recalibrated, and the run reanalyzed. If the ICV fails high and the samples are non-detects,
then they may be reported.
11.3.4 Reporting Limit Verification Standard (RLVS / CRDL): With every Initial Calibration, a
standard corresponding to the Pace reporting limit (PRL) or lower than the derived LLOQ

must also be analyzed and meet established acceptance criteria. The RLVS is analyzed
prior to any samples being analyzed. By client request it will also be analyzed at the end of
the analytical sequence. Additional RLVSs may be analyzed throughout the analytical
sequence at the analyst's discretion. The limits for the RLVS are ± 30% of the true
concentration. These standards are the first calibration standard for the analytes of interest.
The analysis of this standard demonstrates the instruments ability to quantify down to the
reporting limit with known accuracy. If an element fails the CRDL, but the CCV passes and
the samples are greater than the CCV concentration or if the samples are <LOD/ ND, then
the sample data may be reported with the filing of a non-conformance report with the data.
Results >LOD but<CCV must be re-analyzed under passing criteria.
11.3.5 The CCV is analyzed to check for calibration drift. The CCV is run prior to any samples,
after every 10 samples and again at the end of samples. It must quantitate within 10% of
the expected value. Any sample analyzed under out-of-control calibration must be
reanalyzed, following the successful re-calibration of the instrument. If the CCV fails high
and the samples are non-detects, then they may be reported. All others must be re-
analyzed under passing criteria.
11.3.6 The ICB is analyzed to check the accuracy of the curve. The CCBs are analyzed to
check for calibration drift and memory from high concentration samples. In the absence of
Project specificreportinglimits, 1/2the results of the calibration blanks must be less than the
LLOQ (<1/2 the concentration in Cal 1). For the ICB result must be less than one half the
reporting limit (for ease in identifying an issue, reference the first non-zero standard). The
ICB is run after the ICV and the CCBs are run after the CCVs. If the CCB fails high for an
analyte and the samples are non-detects or are greater than 10x the blank value, then they
may be reported. All others must be re-analyzed under passing criteria.
11.4 A batch will consist of 20 or fewer samples. Batch Quality Control will include a Method Blank
(MB), Chicken Blank (CB) (Biota only), Laboratory Control Spike (LCS), Matrix Spike (MS),
Matrix Spike Duplicate (MSD), Post Digestion Spike (PDS), and a Serial Dilution (SD). It may
also include a Laboratory Control Spike Duplicate (LCSD) and/or Standard Reference Material
(SRM).
11.4.1 The Method Blank is used to verify that interferences caused by contaminants in the
solvents, reagents, glassware, etc. are known and minimized. The method blank is
processed through all clean-ups, etc., which were performed on the samples in the batch.
For a method blank to be acceptable, in the absence of project specific criteria, the
concentration shall not be higher than the highest of the following: The reporting limit, or ten
percent of the regulatory limit of concern for that analyte, or ten percent of the measured
concentration in a particular sample of interest. Each sample in the batch is assessed
against the above criteria to determine if the sample results are acceptable. Any sample
associated with an unacceptable blank is either flagged, re-prepped for analysis, or if re-
prepping is not an alternative, the results are reported with the appropriate data qualifying
codes.
11.4.2 The Chicken Blank (CB) must be prepared with every biota batch, and is processed
through all clean-ups, etc., which were performed on the samples. It consists of a control
matrix (ground chicken) to verify the interferences in the biological tissue is known and
minimized. The CB will contain detectable amounts of elements such as K, Ca, Na, Mg,
and P etc., and is used to ensure acceptable performance of the laboratory control spike.

Any detections in the CB greater than the 40CFR Part 136 statistically derived MDL is
subtracted from the LCS/LCSD before recovery limits are evaluated.
11.4.3 A laboratory control sample (LCS) consists of a control matrix, which has been spiked,
with the analytes(s) of interest or compounds representative of those analytes. Laboratory
Control Samples are analyzed at a minimum of 1 per batch of 20 or fewer samples or
preparation method. Results of the LCS are expressed in terms of percent recovery and
are used to determine batch acceptance. Acceptance limits 6020B are 80 to 120% of the
expected concentration. Acceptance limits for 200.8 are 85 to 115% of the expected
concentration. If these limits are not met with the instrument in control, then the entire
batch will be re-digested and re-analyzed.
11.4.4 An LCS Duplicate may be analyzed to evaluate laboratory precision. The LCSD must
also meet the criteria for the LCS. The Relative Percent Difference (RPD)will be calculated
between the LCS and LCSD. The RPD is calculated as outlined below:
RPD = I Di - D2 [ x 100
(Di, + D2,)/2
Where:
RPD = relative percent difference.
Di =first sample value.
D2 = second sample value (duplicate)
The control limit for RPD is 20% or is based on laboratory generated data and not to
exceed 20%. If outside this limit, all associated results are given a R1 data qualifier.
Data generated with LCS samples that fall outside the established acceptance criteria
are judged to be out-of-control. These data are considered suspect and the
corresponding samples are reanalyzed or reported with qualifiers.
For the biota matrix, any detections greater than the MDL must be subtracted from the
LCS/LCSD on-instrument value before calculating the recovery limits.
NOTE: In the event where adequate sample is not supplied by the client to
perform a Matrix Spike/ Matrix Spike Duplicate, the LCS and duplicate can lend
insight on the precision of the analysis.
11.4.5 Matrix spikes (MS and MSD) are performed to evaluate the effect of the sample matrix
upon analytical methodology. A separate aliquot of sample is spiked with the analyte of
interest and analyzed with the sample. For 6020B an MS and MSD are performed at a
minimum frequency of 5% per batch. One pair in 20 samples, per matrix type, per sample
preparation method and are performed more frequently where regulations require. For
200.8, an MS/MSD pair, are performed at a 10% frequency per batch. Matrix spike
recoveries are evaluated against in-house control limits. The recovery must not exceed 75
to 125% of the expected recovery. If outside this recovery, the parent is flagged with an
appropriate data qualifier. If the recovery of an analyte is outside this range but the spike
level in not at least 25% the background concentration in the parent sample, the data is
flagged with an appropriate data qualifier. The RPD between the MS and MSD must be
less than or equal to 20%. If outside this limit, the parent is given an appropriate data
qualifier. The parent sample for the MS/MSD is chosen at random unless specified by a
client. Poor performance in a matrix spike generally indicates a problem with the sample
composition, and not the laboratory analysis, and results are used to assist in data

assessment. A matrix effect is indicated if the LCS data are within acceptance criteria, but
the matrix spike data exceed the acceptance criteria. Prior to calculating recovery, the
parent sample concentration (results <Reporting MDL = 0) is subtracted from the spike
aliquot concentrations.
11.4.6 The Post Digestion Spike (PDS) is run to verify matrix interferences. A spike is added to
a portion of a prepared sample, or its dilution and must be recovered to within 80 to 120
percent of the known value. If the spike is not recovered within the specified limits with the
instrument in control, then the sample has a confirmed matrix effect. Dilute the parent and
re-spike the diluted sample until the PDS recovers within acceptance criteria.
11.4.7 The Serial Dilution (SD) is run to check for matrix interferences. If the analyte
concentration is within the linear dynamic range (LDR) of the instrument and sufficiently
high (minimally, a factor of at least 10 times greater than the lower limit of quantitation for
the diluted sample, 50 times the RLVS standard for the parent sample, or by project/client
specific criteria) an analysis of a fivefold (1+4) dilution must agree within ± 10% of the
original determination for 200.8. For the analysis of 6020B the limit is 25 times the RLVS
standard with the fivefold dilution agreement ± 20%. If these limits are not met, then an
interference effect must be suspected, and the data qualified with an SD data qualifier. If
the analytes of interest are greater than the LDR in the parent sample, the sample can be
diluted, and an SDL done from the dilution. Client specific requirements may require
different reference concentrations and limits.
11.4.8 The type of SRM is typically prepped and analyzed upon client request. It is a sample of

11.6 Method Performance
11.6.1 Detection Limits
11.6.1.1 Detection limits (DL) and limits of quantitation (LOQ) are established at initial
method setup and verified on an on-going basis thereafter. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument
Verification and to the laboratory's SOP ENV-SOP-GBAY-0106 Determination of
LOD and LOQ (most recent revision or replacement)for these procedures.
11.6.1.2 The LOD and LOQ are always adjusted to account for actual amounts used and
for dilution.
11.6.1.3 Current LOD and LOQ can be found in the Laboratory Information Management
System (LIMS)— EpicPro and is subject to change.
11.6.1.4 Level of Detection (LOD): The LOD is determined by the 40CFR Part 136B MDL
study. Once the 40CFR Part 136B MDL is determined it may be elevated if
deemed unrealistic as demonstrated using method blank evaluations.
11.6.2 Periodic performance evaluation (PE) samples are analyzed per ENV-SOP-
GBAY-0107, PE/PT Program (current revision or replacement), to
demonstrate continuing competence. All results are stored in the QA office.
At a minimum, these are performed twice a year for the aqueous and soil
matrices
11.6.3 A linear dynamic range study must be conducted at least once. The study is
conducted for each element by analyzing increasing concentrations (at least
3 levels) until the results generated exceed ±10% difference from the true
value, or another reason the data becomes of unacceptable quality (e.g.
Internal Standard Recovery failure or excessive memory effect). The highest
concentration within the 10% criteria is the maximum of the linear range for
that element. Once the linear dynamic range study determination is

performed, keep the data, as it is useful for the determination of memory
effects from samples and any polyatomic or doubly charged interferences
resulting from a high element concentration in a sample. For the analysis of
samples, the highest standard used in the same calibration event must be
used for the linear range within that analysis set. If the ICS LDR standards at
levels higher than the upper calibrations standard do not meet± 10% the true
value of the standard, then the linear range becomes the same concentration
as the highest calibration standard provided the readback after the linear
regression is 90-100% the expected value. All samples will be diluted and
reanalyzed that are over the linear calibration range.
11.7 Analyst Qualifications and Training
Employees that perform any step of this procedure must have a completed Read and
Acknowledgment Statement for this version of the SOP in their training record. In addition, prior
to unsupervised (independent) work on any client sample, analysts that prepare or analyze
samples must have successful initial demonstration of capability (IDOC) and must successfully
demonstrate on-going proficiency on an annual basis. Successful means the initial and on-going
DOC met criteria, documentation of the DOC is complete, and the DOC record is in the
employee's training file. Refer to laboratory SOP ENV-SOP-GBAY-0094 Orientation and
Training Procedures (most recent revision or replacement)for more information.
12.0 DATA REVIEW AND CORRECTIVE ACTION
12.1 Data Review
Pace's data review process includes a series of checks performed at different stages of the
analytical process by different people to ensure that SOPs were followed, the analytical record is
complete and properly documented, proper corrective actions were taken for QC failure and
other nonconformance(s), and that test results are reported with proper qualification.
The review steps and checks that occur as employee's complete tasks and review their own
work is called primary review.
An experienced peer or supervisor also reviews all data and results. Secondary review is
performed to verify SOPs were followed, that calibration, instrument performance, and QC
criteria were met and/or proper corrective actions were taken, qualitative ID and quantitative
measurement is accurate, all manual integrations are justified and documented in accordance
with the Pace ENV's SOP for manual integration, calculations are correct, the analytical record is
complete and traceable, and that results are properly qualified.
Reporting performs a third-level review, called a completeness check, or project management
staff to verify the data report is not missing information and project specifications were met.
Refer to laboratory SOP ENV-SOP-GBAY-0120 Data Review and Final Report Processes (most
recent revision or replacement) for specific instructions and requirements for each step of the
data review process.
Draw a single-line strikethrough for any unacceptable or changed data, then DATE and INITIAL
and provide a written explanation of the reason for the change.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Data are validated and peer reviewed by lab personnel using a batch cover sheet attached to
the raw data and filed.
Any discrepancies and issues occurring with each batch should be included on the cover sheet
to be incorporated into a narrative.
To assist the primary and secondary reviewer of the data, a spreadsheet (ENV-FRM-GBAY-
0428) was created to copy and paste the calibration curve and initial QC samples into from the
LIMS Link generated bench sheet. This spreadsheet will automatically flag any non-compliant
quality control samples and QC checks.
12.2 Corrective Action
Corrective action is expected any time QC or sample results are not within acceptance criteria.
If corrective action is not taken or was not successful, the decision/outcome must be
documented in the analytical record. The primary analyst has primary responsibility for taking
corrective action when QA/QC criteria are not met. Secondary data reviewers must verify that
appropriate action was taken and/or that results reported with QC failure are properly qualified.
Corrective action is also required when carryover is suspected and when results are over range.
Samples analyzed after a high concentration sample must be checked for carryover and
reanalyzed if carryover is suspected. Carryover is usually indicated by low concentration detects
of the analyte in successive samples analyzed after the high concentration sample.
Sample results at concentrations above the upper limit of quantitation must be diluted and
reanalyzed. The result in the diluted samples should be within the upper half of the calibration
range. Results less than the mid-range of the calibration indicate the sample was over diluted
and analysis should be repeated with a lower level of dilution. If dilution is not performed, any
result reported above the upper range is considered a qualitative measurement and must be
qualified as an estimated value.

1. If not<LOQ,verify by second analysis. If second analysis confirms contamination for target analyte at
or greater than the LOQ, re-digest sample batch and batch QC provided sufficient sample volume
remains. If insufficient sample volume remains, consult with project manager and client on how to
proceed. For MB detections greater than or equal to the LOD, but less than the LOQ; qualify applicable
sample results. For negative measurements more negative than the LOD, applicable data is given the
following data qualifier: "Analyte was measured in the associated method blank at a concentration of-
#.#units."
*For positive MB failures, samples that are non-detection need not be qualified. In addition,samples
that are greater than 10 times the MB detection, need not be qualified.
* For negative MB failures samples that are greater than 10 times the absolute value of the negative MB
measurement, need not be qualified.
2. Verify failure by second analysis. If second analysis confirms LCS(LCSD)failure, re-digest sample
batch and batch QC provided sufficient sample volume remains. If insufficient sample volume remains,
consult with project manager and client on how to proceed.
3. If the parent, MS, or MSD is greater than the reportable linear dynamic range, dilute and reanalyze the
parent, MS, and MSD. If the concentration of the spike is less than 25%of the concentration of the
parent,the MS and MSD recoveries are not evaluated. Any failures resulting from this are qualified
appropriately with a P6 qualifier. If the concentration of the spike is greater than 25%of the
concentration of the parent, appropriately qualify(MO)the parent sample if either the MS and/or MSD
fail accuracy. If the MS and MSD fail precision control limits flag the parent with the appropriate
precision data qualifier(R1).
4. If the spike is not recovered within the specified limits with the instrument in control, dilute the parent
and re-spike the diluted sample until the PS recovers within acceptance criteria.
5. If these limits are not met(as listed in Table 11.5),then an interference effect must be suspected, and
the data qualified with an appropriate data qualifier. If the analytes of interest are greater than the LDR
in the parent sample,the sample can be diluted, and an SDL done from the dilution.
6. If the DUP fails precision control limits flag the parent with the appropriate precision data qualifier
7. For Biota analysis only. Outside of client specific criteria,the SRM is digested and analyzed only to
demonstrate analyte recovery in a standard reference material. When the recovery is outside the lab
generated statistical limits,the element that failed recovery will be flagged in the samples for the
element that failed.Client specific action may also exist.
8. Correct the issue and recalibrate.
9. Verify failure by second analysis. If second analysis confirms ICV failure, correct the issue and
recalibrate the instrument. No data may be reported unless there is a passing ICV for that target
element. If verification passes criteria,then proceed with the analytical sequence.
10. Verify failure by second analysis when possible. If second analysis confirms ICB failure, correct the
issue and recalibrate the instrument. No data may be reported unless there is a passing ICB for that
target element.
11. Verify failure by second analysis. If second analysis confirms ICSA failure,the system is out of control.
Correct the issue and recalibrate the instrument. No data may be reported unless there is a passing
ICSA for that target element.
12. Verify failure by second analysis. If second analysis confirms ICSAB failure,the system is out of
control. Correct the issue and recalibrate the instrument. No data may be reported unless there is a
passing ICSAB for that target element.
13. Verify failure by second analysis when possible. If second analysis confirms CRDL failure,the system
is out of control. Correct the issue and recalibrate the instrument. No data may be reported unless
there is a passing CRDL for that target element. Exceptions; if the sample element concentration is

greater than the CCV concentration and the bracketing CCVs are within control,that sample data may
be reported.
14. Verify failure by second analysis. If second analysis confirms CCV failure,correct the issue and
recalibrate the instrument. On unattended sequence, CCVs may fail and then pass later in the
sequence, but no data may be reported unless bracketed by passing CCVs for that target element.
15. Verify failure by second analysis when possible. If second analysis confirms CCB failure, correct the
issue and recalibrate the instrument. On unattended sequence, CCBs may fail and then pass later in
the sequence, but no data may be reported unless bracketed by passing CCBs. Exceptions;if the
failure is biased high and the sample is a non-detection, or the sample concentration is greater than 10
times the detection in the CCB for that target element. High concentration samples are the likely cause
of a CCB failure. The memory in the sample introduction system was not high enough to cause a CCV
failure, but enough to cause a CCB to fail high.
13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT
Pace proactively seeks ways to minimize waste generated during our work processes. Some
examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent
capture, use of reusable cycletainers for solvent management, and real-time purchasing.
The EPA requires that laboratory waste management practice to be conducted consistent with all
applicable federal and state laws and regulations. Excess reagents, samples and method process
wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's
Chemical Hygiene Plan / Safety Manual.
For further information on waste management, consult ENV-SOP-GBAY-0125 Waste Handling and
Management(most recent revision or replacement).
14.0 MODIFICATIONS
A modification is a change to a reference test method made by the laboratory. For example, changes
in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or
extraction times, instrument runtimes, etc., are all examples of modifications. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification for the
conditions under which the procedures in test method SOPs may be modified and for the procedure
and document requirements.
14.1 When there is insufficient volume provided by the client for the method specified matrix
spike/matrix spike duplicate (MS/MSD), a laboratory control spike duplicate will be analyzed to
demonstrate precision criteria. Laboratory batches will be qualified with the appropriate "M5"
data qualifier. When performing this analysis on paint chip samples, a MS/MSD will not be
completed on the samples due to high levels of elements present in the native sample.
15.0 RESPONSIBILITIES
Pace ENV employees that perform any part this procedure in their work activities must have a signed

TEST METHOD EPA 245.6

1.0 SCOPE AND APPLICATION
This standard operating procedure (SOP)describes the laboratory procedure for the determination of
mercury in biological tissue samples using the CETAC M-7500 instrument.
1.1 Target Analyte List and Limits of Quantitation (LOQ)
Element Symbol CAS# Biota LOQ
(mg/kg)'
Mercury Hg 7439-97-6 0.0188
' Values in place as of effective date of this SOP and are subject to change. For the most up to date LOQ, refer to the
LIMS or contact the laboratory.
LOQ are established in accordance with Pace policy and SOPs for method validation and for the
determination of detection limits (DL) and quantitation limits (LOQ). DL and LOQ are routinely
verified and updated when needed.
The reporting limit (RL) is the value to which analytes are reported as detected or not detected in
the final report. When the RL is less than the lower limit of quantitation (LLOQ), all detects and
non-detects at the RL are qualitative. The LLOQ is the lowest point of the calibration curve used
for each target analyte.
DL, LOQ, and RL are always adjusted to account for actual amounts used and for dilution.
1.2 Applicable Matrices- EPA 245.6 applies biological tissue samples.
1.3 Personnel: The policies and procedures contained in this SOP are applicable to all personnel
involved in the analytical method or non-analytical process.
2.0 SUMMARY OF METHOD
2.1 Cold vapor atomic absorption utilizes the volatile property of elemental mercury at the 253.7
nm wavelength. To release mercury from organic complexes, the sample is digested with
oxidizing reagents and acids in a hot block digester at 58°C, followed by overnight oxidation
with potassium permanganate and potassium per-sulfate at room temperature.
2.2 After digestion, the oxidizing reagents are neutralized by adding hydroxylamine
hydrochloride. The Flow Injection Analysis System sweeps the volatile elemental mercury
out of the sample and into the cell of an atomic absorption spectrophotometer. The
absorbance signal is proportional to the amount of mercury in the sample.
2.3 Results are reported in parts per million (mg/kg).
3.0 INTERFERENCES
3.1 Biota samples can contain diverse matrix types, each of which may present analytical
challenges. Spiked samples and Laboratory Control Samples are important for determining
digestion efficiency.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

3.2 During the oxidation step, chlorides are converted to free chlorine, which also absorbs
radiation at 253.7 nm. Care must therefore be taken to ensure that free chlorine is absent
before the Mercury is reduced and swept into the cell. This may be accomplished by using
an excess of hydroxylamine hydrochloride reagent.
3.3 Certain volatile organic materials that absorb at this wavelength may also interfere. A
preliminary run without reagents may be used to determine if this type of interference is
present.
4.0 DEFINITIONS
Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions.
4.1 Biota Control Blank (Matrix Blank): A sample of a matrix that is used for the control spike.
The biota control blank will either be catfish, tilapia, chicken, or other tissue whichever is
available at the time of analysis. The biota control blank should be "farm-raised" to minimize
background mercury levels. The concentration in the biota control blank will be subtracted
from the concentration of the laboratory control spike when the biota control blank
concentration is greater than/equal to the MDL. This is done because the biota control blank
is known to have some contamination. This SOP will reference biota control blank for ease.
Note: For plant material analysis, alfalfa can be used as the biota control blank matrix.
4.2 Standardized Reference Material (SRM): A certified reference material produced by the U.S.
National Institute of Standards and Technology or other equivalent organization and
characterized for absolute content, independent of analytical method. A SRM is analyzed
with each analytical batch of biota samples.
5.0 HEALTH AND SAFETY
The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully
established. Each chemical should be regarded as a potential health hazard and exposure to these
compounds should be as low as reasonably achievable.
The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the
safe handling of the chemicals specified in each method. Safety data sheets for all hazardous
chemicals are available to all personnel. Employees must abide by the health, safety and
environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene
/Safety Manual.
Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be
worn in designated areas and while handling samples and chemical materials to protect against
physical contact with samples that contain potentially hazardous chemicals and exposure to chemical
materials used in the procedure.
Concentrated corrosives present additional hazards and are damaging to skin and mucus membranes.
Use these acids in a fume hood whenever possible with additional PPE designed for handing these
materials. If eye or skin contact occurs, flush with large volumes of water. When working with acids,
always add acid to water to prevent violent reactions. Any processes that emit large volumes of
solvents (evaporation/concentration processes) must be in a hood or apparatus that prevents
employee exposure.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Extreme caution must be used when preparing rodents for digestion. The samples must undergo a
special procedure to destroy any Hantavirus, which may be present. Refer to the most recent version
of SOP ENV-SOP-GBAY-0130 Small Rodent Handling and Homogenization for details.
Contact your supervisor or local HSE coordinator with questions or concerns regarding safety protocol
or safe handling procedures for this procedure.
6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE
Samples should be collected in accordance with a sampling plan and procedures appropriate to
achieve the regulatory, scientific, and data quality objectives for the project.
The laboratory does not perform sample collection or field measurements for this test method. To
assure sample collection and field checks and treatment are performed in accordance with applicable
regulations Pace project managers will inform the client of these requirements at the time of request
for analytical services when the request for testing is received prior to sample collection. If samples
were already collected, the laboratory will record any nonconformance to these requirements in the
laboratory's sample receipt record when sufficient information about sample collection is provided with
the samples.
The laboratory will provide containers for the collection of samples upon client request for analytical
services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle
Preparation (current revision or replacement).
6.1 Where applicable, the bottle ware is demonstrated to be fee of target analytes. When bottle
ware not originating from the lab is used, the data may be qualified with either one or both of
the following data qualifiers:
6.1.1 Sample field preservation does not meet EPA or method recommendations for this
analysis.
6.1.2 Sample container did not meet EPA or method requirements.
Requirements for container type, preservation, and field quality control (QC)for the common list of test
methods offered by Pace are included in the laboratory's Quality Manual.

9.1 Analytical Balance Procedures:
9.1.1 Annual Calibration:The balance must be calibrated at least annually by an outside agency
and checked daily before each use using Class 1 or 2 weights. Refer to Pace SOP ENV-
SOP-GBAY-0115 Support Equipment(most recent revision or replacement.
9.1.2 Daily Calibration Check:
9.1.2.1 Clean the balance and surrounding area prior to starting the daily calibration
check.
9.1.2.2 Check the sight level on the balance. If it needs adjusting, level the balance.
9.1.2.3 The weight set ID indicated in the logbook is used as the primary set. If an
alternate weight set ID is used, that ID must be recorded in the comment section
of the balance calibration logbook for that day.
9.1.2.4 Tare the balance before weighing the NIST certified weights.
9.1.2.5 Use forceps or other means to lift each weight (Do not touch the weights with
fingertips as the residue may artificially adjust the true value of the weights).
Record the date of the calibration check, the true value of the weight, and the
actual measured weight in the logbook. Repeat this procedure for the other
certified weights. If calibration weights differ from the certified weights by more
than specified in the balance calibration logbook, corrective action must be taken.
9.1.3 Corrective Action Procedures:
9.1.3.1 Clean the balance and balance pan. Check the sight level on the balance and
adjust if necessary. Re-tare and reweigh all the certified weights.
9.1.3.2 The internal calibration function (if available) of the balance may be used as a
means of corrective action.
9.1.3.3 Utilize the internal calibration function and diagnostics. Refer to instrument
manual.

9.5.4.2 The %RE of the lowest calibration points must be within ±40% of the true value.
9.5.4.3 The %RE of the remaining calibration points must be within ±10% of their true
value.
9.5.5 Corrective action: The instrument must be recalibrated and or the calibration curve and
the associated samples must be re-prepped.
9.5.6 Calibration Verification: The calibration curve must be validated by acceptable analysis of
applicable instrument QC. At a minimum these included ICV, ICB, CRDL, CCV(s), and
CCB(s). See section 11 for more details on calibration verification QC.
9.5.7 See Attachment I: QC Summary and laboratory SOP: ENV-SOP-GBAY-0138, Calibration
Procedures (most recent revision or replacement)for additional guidance.
9.6 Biological Tissue Sample Digestion (EPA 245.6):
9.6.1 50 mL digestion vials are used for Biota samples.
9.6.2 Prior to analysis the samples and calibration curve must be digested.
9.6.3 Turn on the hot block and set the temperature to maintain a sample temperature of 58±3°C.
Before placing samples in the hot block to digest, use a temperature blank to verify that
the block temperature is correct and adjust as required. Record the temperature in the
electronic prep log. Verify that the hood is functioning.
9.6.4 Add 2.5 mL of Nano-Pure water and add the appropriate amounts (as shown in Section
8.3) of Hg Calibration Intermediate and Hg ICV Intermediate to digestion vials for the curve,
ICV, CCV, ICB, and CCB. Additional blanks (and standards) may be prepared to be used
as continuing calibration blanks and calibration check standards and to be used as diluent
in cases where the sample concentration exceeds the high point of the calibration curve or
matrix interferences are observed.
9.6.5 Prepare one Method Blank. For biota analysis, leave the Method Blank empty. A Biota
Control Blank is also prepared by weighing 0.6 g of homogenized biota control blank tissue
(chicken) into a digestion vial.
9.6.6 Prepare the LCS for biota samples by weighing 0.6 g of homogenized biota control blank
1 into the digestion vial. Add 2.5 mL of Hg ICV Intermediate (100 pg/L CVAA Hg Spk) the
vial. Only prep a Laboratory Control Spike Duplicate (LCSD) if requested by client or there
is not enough sample to run a MS/MSD. Prepare the LCSD in the same fashion as the
LCS.
9.6.7 For biota samples, weigh approximately 0.05 g of Standard Reference Material into a
labeled digestion vial (DORM-4 or equivalent).
9.6.8 Weigh 0.6 g of homogenized sample into a labeled digestion vial. Record the weight to
the nearest 0.01 g in the digestion prep log. Try to minimize any thawing of the sample
during the weighing process to prevent fluid migration within the tissue.
9.6.9 To prepare a Matrix Spike and Matrix Spike Duplicate, a sample with sufficient volume is
chosen at random. Weigh 2 additional 0.6g aliquots into digestion vials. Add 2.5 mL of Hg
ICV Intermediate (100 pg/L CVAA Hg Spk)to each vial.
9.6.10 To each digestion vial add 2.0 mL of concentrated sulfuric acid and 0.5mL of concentrated
nitric acid and cap loosely. Swirl digestion vials to gently mix.

9.6.11 Heat the samples, standards and SRM for 1 hour on a hot block set to reach 58±3°C (soft
tissue should be completely dissolved).
9.6.12 Remove the vessels from the hot block and cool in an ice bath, or pack ice around the
samples for at least one hour.
9.6.13 Slowly add 7.5 mL of 5%KMnOato all samples and batch QC. Samples may react violently
if added too quickly.
9.6.14 To each sample, including QC, add 4 mL of potassium persulfate solution, cap loosely, and
allow the samples to sit overnight at room temperature.
9.6.15 To each sample, including QC, add 3 mL of hydroxylamine solution to decolorize it and let
sit for about two hours (capped)to allow gases to diffuse out of solution.
9.6.16 Bring to a final volume of 50 mL with water.
9.6.17 All samples and QC need to be diluted by a dilution factor of 5. Add 2.0 mL of sample to
a digestion vessel. Dilute the sample by adding 8.0 mL of blank water that has been
digested by the EPA 245.6 method.
9.7 Dry Ice Blank and Blender Blank Preparation:
9.7.1 Dry Ice Blank-Add 50 mL of DI water and 1.0 mL of nitric acid to Dry Ice Blank jar sent by
sampler.
9.7.2 Blender Blank — Rinse blender with 50 mL of DI water acidified with 1 mL of nitric acid.
Collect in sample container and label as Blender Blank.
9.7.3 Close each sample jar, shake well, and let stand for at least 30 minutes.
9.7.4 Pipette a 25 mL aliquot of the prepared sample into a sample digestion vessel. This
procedure will allow enough sample digestate for one re-analysis, if necessary.
9.7.5 Digest the dry ice blank and blender blank.
9.7.6 See Section 10 for calculation of results for dry ice blanks and blender blanks.
9.8 Dilutions: All reported results must be within the range of the calibration curve. Dilute when
results are greater than the high standard in the curve. Dilutions on sample extracts must be
prepared in a volumetric fashion. Sample aliquots should be taken with a calibrated pipette
and brought to an appropriate final volume. In the event a dilution is made to bring a target
analyte into calibration range, the analyst should make a dilution such that the target analyte
is roughly the equivalent of the mid calibration point whenever possible.
9.9 CETAC M-7500 Basic System Operation (Analytical): This portion of the SOP is designed
to allow the user to set up and run a method, print a sample report, then shut down using the
more basic software functions. For a more detailed explanation of the many other options,

1 10.3 Quality Control Results: Calculate recoveries for the spiked analytes in LCS/LCSD and
MS/MSD samples; and Relative Percent Differences (RPD) for duplicate and MS/MSD
samples. See current revision or replacement of SOP ENV-SOP-GBAY-0153, Laboratory
Calculations for additional information.
11.0 QUALITY CONTROL AND METHOD PERFORMANCE
11.1 Initial Calibration (ICAL):
11.1.1 Frequency: A calibration must be performed daily with samples when they are prepared.
11.1.2 Acceptance Criteria: The resultant correlation coefficient must be greater than 0.995.
The calculate concentration of the low point of the calibration curve must be within ±40%
of the true value (relative error<_40%). The calculate concentration of the remainder of the
calibration curve must be within ±10% of their true value (relative error<_10%).
11.1.3 Corrective Action: If outside acceptance criteria, the problem must be corrected, the
instrument re-calibrated, and quality control within criteria achieved before continuing and
the affected samples reanalyzed.
11.2 Instrument Quality Control: Instrument QC consists of an ICV ICB, CRDL, and CCV(s)
and CCB(s).
11.2.1 Initial Calibration Verification (ICV): The ICV is a second source standard used to verify
the calibration, also known as the Quality Control Sample (QCS).
11.2.1.1 Frequency: Immediately after the ICAL and prior to sample analysis.
11.2.1.2 Acceptance Criteria: The result of the ICV must fall within the range of 90%-
110% of the true value.
11.2.1.3 Corrective Action: If outside acceptance criteria, the problem must be
corrected,the instrument re-calibrated, and quality control within criteria achieved
before continuing and the affected samples reanalyzed.
11.2.2 Continuing Calibration Verification (CCV): The CCV is the same source as the ICAL at
the midpoint of the calibration curve used to verify the calibration throughout the analytical
run.
11.2.2.1 Frequency: A CCV is analyzed prior to sample analysis, every 10 injections and
at the end of the analytical sequence.
11.2.2.2 Acceptance Criteria: CCV limits are± 10% of their expected values.
11.2.2.3 Corrective Action: If a CCV is outside of the control limits, a verification I CCV
can be immediately analyzed. If the verification CCV is outside of control limits,
the problem must be corrected, and the instrument recalibrated prior to any
reportable samples being analyzed.
11.2.3 Calibration Blanks: Calibration blanks (ICB and CCB)
11.2.3.1 Frequency: The ICB is analyzed immediately following the ICV and a CCB is
analyzed immediately following any CCV.
1 11.2.3.2 Acceptance Criteria: ICB and CCBs may not contain concentrations in excess
of the LOQ.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

11.2.3.3 Corrective Action: If a blank is outside of the control limits, a verification blank
can be immediately analyzed. If the verification blank is outside of control limits,
the problem must be corrected, and the instrument recalibrated prior to any
reportable samples being analyzed.
11.2.4 Pace Reporting Limit Standard (CRDL): A standard prepared at the concentration of the
lowest calibration point.
11.2.4.1 Frequency: It is analyzed after the ICV/ICB.
11.2.4.2 Acceptance Criteria: The recovery must be within 60-140% recovery of the true
value.
11.2.4.3 Corrective Action: If a CRDL is outside of the control limits, a verification CRDL
can be immediately analyzed. If the verification CRDL is outside of control limits,
the problem must be corrected, and the instrument recalibrated prior to any
reportable samples being analyzed.
11.3 Batch Quality Control: Batch QC consists typically of a MB, LCS(LCSD), MS/MSD, and
SRM. These are prepared and analyzed with each batch of samples. A batch will consist of
up to 20 samples. In some cases, a DUP may be analyzed in a batch.
11.3.1 Method Blank: The MB is laboratory grade water and is carried through all preparation
procedures . The MB is used to verify that interferences caused by contaminants in the
solvents, reagents, glassware, etc. are known and minimized. For dissolved samples
filtered in-house, a filter blank is created. The filter blank is evaluated and qualified the
same as a method blank.
11.3.1.1 Frequency: A MB must be analyzed with each batch of samples or every 20
samples, whichever is more frequent.
11.3.1.2 Acceptance Criteria: The MB is evaluated for both positive and negative bias
and must have an absolute value less than the LOQ. For samples reporting down
to the LOD, the MB measurements are evaluated to the LOD. In these cases,
qualify applicable samples for MB measurements from >LOD to <LOQ.
11.3.1.3 Corrective Action: If the MB is greater than the LOQ, perform the following:
11.3.1.3.1 Check for errors in calculations. If an error or problem is found and
can be corrected by amending the calculations and the result falls
within the limits, accept the data and report without a qualifier flag.
11.3.1.3.2 If there is sufficient sample available and hold time remaining, re-
prepare the MB and all associated. If the MB is less than the LOQ in
this analysis, accept the second set of data. If the MB is still outside
the RL after re-analysis, contact the PM to determine the resolution.
If the client does not require additional work, report the data, applying
an appropriate flag to the samples associated with the non-compliant
MB.
11.3.1.3.3 If sufficient sample volume is not available, report the sample data
with a qualifier flag on each of the samples associated with the non-
compliant MB. Contact the project manager regarding the
occurrence.

11.3.1.4 MB data qualifying:
11.3.1.4.1 In the absence of project specific requirements, samples with
concentrations greater than 10 times the absolute blank
measurement may be reported unqualified.
11.3.1.4.2 In the absence of project specific requirements, samples that are non-
detect may be reported unqualified if the blank measurement
demonstrates a positive bias.
11.3.1.4.3 In the absence of project specific requirements,samples that are non-
detect must be qualified if the blank measurement demonstrates a
negative bias between and including the LOD and LOQ. Non-detect
samples may not be reported with a blank negative bias greater than
the LOQ.
11.3.1.4.4 For samples that need qualification resulting from MB measurements
that are positive, apply a B data qualifier to the analyte. B = "Analyte
was detected in the associated method blank."
11.3.1.4.5 For samples that need qualification resulting from MB measurements
that are negative, apply a hand entered qualifier with the
measurement and the units. "Analyte was measured in the
associated method blank at a concentration of-#.# units."
11.3.2 Laboratory Control Spike/ Laboratory Control Spike Duplicate(LCS/LCSD):The LCS
is carried through all preparation procedures and is made from a standard different from
that of the calibration curve.
11.3.2.1 LCS Frequency: The LCS is performed at a frequency of 5%, or one per batch
of up to 20 environmental samples. An LCSD must be analyzed if there is
insufficient sample volume to perform a MS/MSD or if the client requests one.
11.3.2.2 Acceptance Criteria: For method 245.6 the acceptance criterion is 85-115%
recovery. The acceptance criterion for precision is 520% RPD.
11.3.2.3 Corrective Action: If the LCS or LCSD is outside of acceptance criterion,
reanalyze once to verify failure. If still outside the limits, determine/correct the
problem, re-digest and re-analyze the entire batch.
11.3.3 Matrix Spike/Matrix Spike Duplicate (MS/MSD): The sample used for the MS/MSD pair
is either determined by the client or selected at random from client samples as sample
volume allows. No field, filter, trip, or equipment blanks can be used for MS/MSD.
11.3.3.1 Frequency: One matrix spike and matrix spike duplicate are analyzed at a
frequency of 10% for EPA 245.6.
11.3.3.2 Acceptance Criteria: For method 245.6 the accuracy acceptance criterion is 70-
130%. The precision acceptance criterion is 520% RPD.
11.3.3.3 Corrective Action: If the MS/MSD accuracy and/or precision recoveries are
outside control limits, qualify the parent sample and MS/MSD results with an
appropriate data qualifier.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

11.3.4 Sample Duplicate (DUP):
11.3.4.1 Frequency: Typically, the method requirements for duplicate sample analysis
are met with the use of an MSD or LCSD but based on client request a DUP(s)
may also be prepared and analyzed. Parent sample is chosen at random or
assigned by the client.
11.3.4.2 Acceptance Criteria: The precision acceptance criterion is _. 20% RPD.
11.3.4.3 Corrective Action: If the RPD is outside of acceptance criterion, then the parent
sample and DUP are given an appropriate data qualifier.
11.3.5 Standard Reference Material (SRM): An SRM is a purchased standard reference with a
documented concentration from a similar matrix (Biota) and is carried through all
preparation procedures with the samples.
11.3.5.1 Frequency: An SRM must be analyzed with each batch of samples or every 20
samples, whichever is more frequent.
11.3.5.2 Acceptance Criteria: The default acceptance criteria is±20% recovery from the
certificate of analysis provide for the SRM.
11.3.5.3 Corrective Action: The SRM is given a data qualifier stating that it the recovery
exceeds the default limits.
11.4 Hold Time:When preparation of a sample exceeds 28 days past the time of collection, notify
the project manager before proceeding. If a sample is run past 28 days after collection, flag
the result with appropriate data qualifier.
11.5 Dilution: If a sample was diluted due to matrix effects and the result is a non-detect, the
result must be qualified with appropriate data qualifier.
11.6 Method Performance
11.6.1 Method Validation
11.6.1.1 Detection Limits
Detection limits (DL) and limits of quantitation (LOQ) are established at initial
method setup and verified on an on-going basis thereafter. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument
Verification (current revision or replacement) and to the laboratory's SOP ENV-
SOP-GBAY-0106 Determination of the LOD and LOQ (current revision or
replacement)for these procedures.
The LOD and LOQ are always adjusted to account for actual amounts used and
for dilution.
Current LOD and LOQ can be found in the Laboratory Information Management
System (LIMS) - EpicPro.
Level of Detection (LOD): The LOD is determined by the 40CFR Part 136B MDL
study. Once the 40CFR Part 136B MDL is determined it may be elevated if
deemed unrealistic as demonstrated using method blank evaluations.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

11.6.1.2 Linear Dynamic Range: This method is for determination of Hg in the range of
0.2-10 pg/L. Application may be extended to higher levels by selection of a
smaller sample size or by calibration of the analytical system across a higher
range. Since the calibration used only extends to 10 pg/L, the reportable linear
range will not exceed 10 pg/L.
11.6.1.3 Periodic performance evaluation (PE) samples
Periodic performance evaluation (PE) samples are analyzed per ENV-SOP-
GBAY-0107, PE/PT Program (most recent revision or replacement), to
demonstrate continuing competence. All results are stored in the QA office.
1 11.6.2 Analyst Qualifications and Training
Employees that perform any step of this procedure must have a completed Read and
Acknowledgment Statement for this version of the SOP in their training record. In addition,
prior to unsupervised (independent) work on any client sample, analysts that prepare or
analyze samples must have successful initial demonstration of capability (IDOC) and must
successfully demonstrate on-going proficiency on an annual basis. Successful means the
initial and on-going DOC met criteria, documentation of the DOC is complete, and the DOC
record is in the employee's training file. Refer to laboratory SOP ENV-SOP-GBAY-0094
Employee Orientation and Training Procedures (current revision or replacement)for more
information.
12.0 DATA REVIEW AND CORRECTIVE ACTION
12.1 Data Review
Pace's data review process includes a series of checks performed at different stages of the
analytical process by different people to ensure that SOPs were followed, the analytical record is
complete and properly documented, proper corrective actions were taken for QC failure and other
nonconformance(s), and that test results are reported with proper qualification.
The review steps and checks that occur as employees complete tasks and review their own work
are called primary review.
All data and results are also reviewed by an experienced peer or supervisor. Secondary review
is performed to verify SOPs were followed, that calibration, instrument performance, and QC
criteria were met and/or proper corrective actions were taken, qualitative ID and quantitative
measurement is accurate, all manual integrations are justified and documented in accordance with
the Pace ENV's SOP for manual integration, calculations are correct, the analytical record is
complete and traceable, and that results are properly qualified.
A third-level review, called a completeness check, is performed by reporting or project
management staff to verify the data report is not missing information and project specifications
were met.
Draw a single-line strikethrough for any unacceptable or changed data, then DATE and INITIAL
and provide a written explanation of the reason for the change.
Any discrepancies and issues occurring with each batch should be included on the cover sheet to
be incorporated into a narrative.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Refer to laboratory SOP ENV-SOP-GBAY-0120 Data Review and Final Report Processes (most
recent revision or replacement)for specific instructions and requirements for each step of the data
review process.
12.2 Corrective Action
Corrective action is expected any time QC or sample results are not within acceptance criteria. If
corrective action is not taken or was not successful, the decision/outcome must be documented
in the analytical record. The primary analyst has primary responsibility for taking corrective action
when QA/QC criteria are not met. Secondary data reviewers must verify that appropriate action
was taken and/or that results reported with QC failure are properly qualified.
Corrective action is also required when carryover is suspected and when results are over range.
Samples analyzed after a high concentration sample must be checked for carryover and
reanalyzed if carryover is suspected. Carryover is usually indicated by low concentration detects
of the analyte in successive samples analyzed after the high concentration sample.
Sample results at concentrations above the upper limit of quantitation must be diluted and
reanalyzed. The result in the diluted samples should be within the upper half of the calibration
range. Results less than the mid-range of the calibration indicate the sample was over diluted and
analysis should be repeated with a lower level of dilution. If dilution is not performed, any result
reported above the upper range is considered a qualitative measurement and must be qualified
as an estimated value.
13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT
Pace proactively seeks ways to minimize waste generated during our work processes. Some
examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent
capture, use of reusable cycletainers for solvent management, and real-time purchasing.
Regulated soil samples are to be handled in accordance with Pace SOP: ENV-SOP-GBAY-0121,
Regulated Soil Handling (current revision or replacement).
The EPA requires that laboratory waste management practice to be conducted consistent with all
applicable federal and state laws and regulations. Excess reagents, samples and method process
wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's
Chemical Hygiene Plan/Safety Manual.
14.0 MODIFICATIONS
A modification is a change to a reference test method made by the laboratory. For example, changes
in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or
extraction times, instrument runtimes, etc. are all examples of modifications. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(current revision
or replacement)for the conditions under which the procedures in test method SOPs may be modified
and for the procedure and document requirements.
EPA method 245.6 Rev.2.3 1991; throughout the document equipment and supplies are mentioned
that have had advances in technology. This has resulted in differences in descriptions (11.2 circulating
pump) and procedures (11.6.1 Placing the aspirator inside the BOD bottle)from the method.

EPA method 245.6 Rev.2.3 1991 Section 7.7 lists the stannous chloride solution as being made using
H2SO4. The lab uses a 10 % SnCl2 solution made up with a final acid concentration of 7% HCI. This
is based on Section 4.1.2 of Quicktrace M-7500 Automated Mercury Analyzer.
According to Method 200.3, section 8; Samples should be placed in plastic bag, sealed, and placed
on ice or refrigerated at 4 degrees Celsius. The lab practice is to have thermal preservation at 5_6°C.
The lab bases this on 40CFR Part 136, page 29808, footnote 18. While Biota is not listed as a matrix,
this is consistent with temperature references of EPA methods at 4 degrees Celsius.
According to Method 200.3, section 8; Dissection should be performed within 24 hours of collection.
This is not practical as sampling events take days or even weeks to complete. This is why the lab
prefers to have samples frozen and shipped to the lab frozen.
According to Method 200.3, section 8; Tissue can also be frozen at < -20 degrees Celsius. The lab
uses the criteria of< -10 degrees Celsius for storage of frozen biota samples.
The preparation of Stannous Chloride solution differs from EPA 245.1: automated mercury analyzers
with reduced concentration of stannous chloride have been deemed equivalent.
Prepare calibration standards as liquid standards. (This is different from Method 245.6 which specifies
preparing calibration tissues directly in a tissue matrix).
EPA 245.6 Rev.2.3 1991, section 6.10 describes a water bath as follows: The water bath should have
a covered top and capacity to sustain a water depth of 2-in. to 3-in. at 95°C+1°C. Nowhere in the
document is a temperature acceptance range given for the operating temperature of 58°C. The lab
follows the criteria of +3°C from similar methodology of SW846 7471 B Rev.2 2007 and also uses a
hot block.
For EPA 245.6 Rev.2.3 1991, the lab has chosen to use a 0.6g sample volume instead of the method
specified 0.2-0.3g in section 8.3. In section 11.1, 4 mL of conc. H2SO4 and 1 mL of conc. HNO3 are
added. The lab uses 2.0 mL of conc. H2SO4 and 0.5 mL of conc. HNO3. In section 11.2 5 mL of
potassium permanganate and 8 mL of potassium persulfate are added. The lab uses 7.5 mL of
potassium permanganate and 4 mL of potassium persulfate. The lab has established this procedure
for re-occurring project work with many years of historical.

1. If calibration criteria are not met, perform maintenance and recalibrate.
2. If ICV/CCV is outside the control limits reanalyze the ICV/CCV to verify the instrument is out of control. If the 2nd
analysis is outside control limits, perform maintenance and recalibrate. Samples that bracket the out of control
standards must be reanalyzed.
3. If ICB/CCB is outside the control limits reanalyze the ICB/CCB to verify the instrument is out of control. If the 2nd

7. If the parent, MS,or MSD is greater than the reportable linear dynamic range, dilute and reanalyze the parent, MS,
and MSD. If the concentration of the spike is less than 25%of the concentration of the parent,the MS and MSD
recoveries are not evaluated. Any failures resulting from this are qualified appropriately. If the concentration of
the spike is greater than 25% of the concentration of the parent,appropriately qualify the parent sample if either
the MS and/or MSD fail accuracy. If the MS and MSD fail precision control limits flag the parent with the appropriate
precision data qualifier.
8. If the precision control exceeds limits flag the DUP and parent with the appropriate precision data qualifier.
9. The SRM is given a data qualifier stating that it the recovery exceeds the default limits.
10. Notify Project Manager by submitting a LabTrack Ticket and flag with the appropriate data qualifier.

2.0 SUMMARY OF METHOD
2.1 An aliquot (0.500g to 0.575g) of sample is weighed into a digestion tube. Applicable analytes
are listed in the Target Analyte List.
2.2 The sample is acidified with nitric acid and heated on an apparatus with additions of nitric acid,
hydrogen peroxide, and hydrochloric acid.
2.3 The digestate is brought to a 50 mL final volume with reagent water, and either centrifuged,
allowed to settle, or filtered.
2.4 This process is to extract the metals from the biota matrix so it can go through multi-element
analysis by ICPMS.
3.0 INTERFERENCES
3.1 Cross contamination from standards and samples containing high concentrations is possible. It
is critical that the metals digestion (prep) lab is kept in a clean organized manner to minimize
any possible cross contamination.
3.2 Isobaric Polyatomic Interferences — Isobaric polyatomic interferences result when ions
containing more than one atom have the same nominal mass-to-charge ratio as an analyte of
interest and cannot be resolved by the instrument's spectrometer. An example includes CIO+
(mass 51), which interferes with V, and must be corrected by measuring CIO+ at mass 53.
When possible, an interference free isotope should be chosen for measurement.
3.3 Chromic acid should never be used to clean any container used in metals analysis.
3.4 Borosilicate glass in sample containers can lead to interference of Boron concentrations in
samples. This is also true of volumetric flasks, thus when dilution in the flask is complete the
standards must be removed as soon as possible from the dilution container and placed into a
clean plastic container.
4.0 DEFINITIONS
Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions.
5.0 HEALTH AND SAFETY
The toxicity or carcinogenicity of each chemical material used in the laboratory has not been fully
established. Each chemical should be regarded as a potential health hazard and exposure to these
compounds should be as low as reasonably achievable.
The laboratory maintains documentation of hazard assessments and OSHA regulations regarding
the safe handling of the chemicals specified in each method. Safety data sheets for all hazardous
chemicals are available to all personnel. Employees must abide by the health, safety and
environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical
Hygiene /Safety Manual.
Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be
worn in designated areas and while handling samples and chemical materials to protect against
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

physical contact with samples that contain potentially hazardous chemicals and exposure to
chemical materials used in the procedure.
Concentrated corrosives present additional hazards and are damaging to skin and mucus
membranes. Use these acids in a fume hood whenever possible with additional PPE designed for
handing these materials. If eye or skin contact occurs, flush with large volumes of water. When
working with acids, always add acid to water to prevent violent reactions. Any processes that emit
large volumes of solvents (evaporation/concentration processes) must be in a hood or apparatus that
prevents employee exposure.
Contact your supervisor or local HSE coordinator with questions or concerns regarding safety
protocol or safe handling procedures for this procedure.
6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE
Requirements for container type, preservation, and field quality control (QC) for the common list of
test methods offered by Pace are included in the laboratory's quality manual.
Samples should be collected in accordance with a sampling plan and procedures appropriate to
achieve the regulatory, scientific, and data quality objectives for the project.
The laboratory will provide containers for the collection of samples upon client request for analytical
services. Bottle kits are prepared in accordance with laboratory SOP ENV-SOP-GBAY-0007 Bottle
Preparation.
6.1 All sample containers must be HDPE, glass, or Teflon. The containers are purchased pre-
cleaned and documented to be contaminant free. Where applicable, the bottle ware is
demonstrated to be free of target analytes. When bottle ware not originating from the lab is
used, the data may be qualified with either one or both of the following data qualifiers:
6.1.1 Sample field preservation does not meet EPA or method recommendations for this
analysis.
6.1.2 Sample container did not meet EPA or method requirements.

9.0 PROCEDURE
9.1 Calibration Procedures:
9.1.1 Analytical Balance Calibration
9.1.1.1 Annual Calibration —The balance must be calibrated at least annually by an
outside agency and checked daily before each use using Class 1 or 2
weights. Refer to Pace SOP ENV-SOP-GBAY-0115 Support Equipment
(most recent revision or replacement).
9.1.1.2 Daily Calibration Check
9.1.1.2.1 Clean the balance and surrounding area prior to starting the daily
calibration check.
9.1.1.2.2 Check the sight level on the balance. If it needs adjusting, level
the balance.
9.1.1.2.3 The weight set ID indicated in the logbook is used as the primary
set. If an alternate weight set ID is used, that ID must be recorded
in the comment section of the balance calibration logbook for that
day.
9.1.1.2.4 Tare the balance before weighing the NIST certified weights.
9.1.1.2.5 Use forceps or other means to lift each weight (Do not touch the
weights with fingertips as the residue may artificially adjust the true
value of the weights). Record the date of the calibration check, the
true value of the weight, and the actual measured weight in the
logbook. Repeat this procedure for the other certified weights. If
calibration weights differ from the certified weights by more than
specified in the balance calibration logbook, corrective action must
be taken.
9.1.1.3 Corrective Action
9.1.1.3.1 Clean the balance and balance pan. Check the sight level on the
balance and adjust if necessary. Re-tare and reweigh all the
certified weights.
9.1.1.3.2 The internal calibration function (if available) of the balance may be
used as a means of corrective action.
9.1.1.3.3 Utilize the internal calibration function and diagnostics. Refer to
instrument manual.
9.1.1.3.4 Contact the QA office for assistance if the balance does not meet
the calibration tolerances.
9.1.1.3.5 If the above action does not correct the problem, the balance
should be taken out of service and appropriately labeled to avoid
improper usage. A service technician should be contacted.
9.1.1.3.6 Record any corrective action. Initial and date all entries in the
logbook.
9.1.2 Thermometer - See the most recent revision of the SOP ENV-SOP-GBAY-0115,
Support Equipment for thermometer calibration and validation.

9.1.3 Pipette/Bottle Top Dispenser - See the most recent revision of the SOP ENV-SOP-
GBAY-0115, Support Equipment for volumetric dispensing device calibration and
validation.
9.2 Digestion Procedures:
9.2.1 Heat hot block at 95°C ± 5°C (verify temperature with a calibrated thermometer). A
random well is used for each verification. The block has a full temperature evaluation
performed minimally each year. The temperature will be record in the Electronic Prep
Log in accordance with EPIC Pro Training Module 16: Electronic Prep Log Guide
(most recent revision or equivalent).
9.2.2 Batch samples in the LIMS. Identify QC samples at the frequency stated in the Quality
Control Section of this SOP. Additional samples may be added to the batch, so long as 1
the total sample number in the batch does not exceed 20. The digestion of the
additional samples must begin within eight hours of the start of the original digestion.
9.2.3 Log into the Electronic Prep Log. Create a new prep sheet using the
3050B1ICP_ICPMS Soil Template and the LIMS Batch HBN.
9.2.4 Verify sample IDs and LIMs numbers on containers against the prep sheet.
9.2.5 To the extent possible, mix and crush the sample as per SOP ENV-SOP-GBAY-0129,
Sample Homogenization, Compositing, and Sub-sampling (most recent revision or
replacement), in the sample container with a disposable plastic spatula to achieve
homogeneity. Tissue samples with sufficient sample volume are typically blended with
liquid nitrogen to achieve a light fluffy texture. Small volume tissue samples and
vegetative samples may be cut up.
9.2.6 Prepare Method Blank (MB) by leaving the digestion tube empty.
9.2.7 Prepare a Solid Matrix Blank (typically chicken) by weight 0.500-0.504g of blended
chicken into one digestion tube. Record sample weight in digestion log.
9.2.8 Prepare an SRM by weighing exactly 0.500g of the SRM into one digestion tube.
Record sample weight in digestion log.
9.2.9 Prepare Laboratory Control Spike (LCS) by weighing —0.500g of solid matrix material
(typically chicken) in digestion tube. Add 1.0 mL of the Biota Spike and 1.0 mL of the
Biota Spike Ag to the LCS digestion tube. Spikes may be adjusted based on client
requests.
9.2.10 Laboratory Spike Duplicate (LCSD) if there is insufficient volume for an MS/MSD. The
LCSD may be required per client request.
9.2.11 Prepare Matrix Spike / Matrix Spike Duplicate (MS/MSD), by weighing 0.500 to 0.504
grams of parent sample into 3 separate digestion tubes. Record sample weight to
nearest 0.001 gram on digestion log. Parent, MS, and MSD should be approximately
the same weight. Add 1.0 mL of the Biota Spike and 1.0 mL of the Biota Spike Ag to
the MS/MSD digestion tubes. Spikes may be adjusted based on client request.
9.2.12 Weigh 0.500 to 0.575g of homogenized sample into a labeled digestion tube. Record
sample weight to nearest 0.001 g on digestion log. Do this for each sample in the
digestion batch. Record all information in the Electronic Prep Log worksheet. Note: If
a sample contains a significant amount of water a larger mass may be used.

10.0 DATA ANALYSIS AND CALCULATIONS
10.1 Not applicable to this SOP.
11.0 QUALITY CONTROL AND METHOD PERFORMANCE
11.1 A batch will consist of 20 or fewer samples. Batch Quality Control will include a Method Blank
(MB), Laboratory Control Spike (LCS), Matrix Spike (MS), Matrix Spike Duplicate (MSD), Post
Digestion Spike (PDS), and a Serial Dilution (SD). It may also include a Laboratory Control
Spike Duplicate (LCSD) and/or Standard Reference Material (SRM).
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

11.1.1 The Method Blank is used to verify that interferences caused by contaminants in the
solvents, reagents, glassware, etc. are known and minimized. The method blank is
processed through all clean-ups, etc., which were performed on the samples in the
batch. For a method blank to be acceptable, in the absence of project specific criteria,
the concentration shall not be higher than the highest of the following: The reporting
limit, or ten percent of the regulatory limit of concern for that analyte, or ten percent of
the measured concentration in a particular sample of interest. Each sample in the batch
is assessed against the above criteria to determine if the sample results are
acceptable. Any sample associated with an unacceptable blank is either flagged, re-
prepped for analysis, or if re-prepping is not an alternative, the results are reported with
the appropriate data qualifying codes.
11.1.2 LCS: A laboratory control sample (LCS) consists of a control matrix, which has been
spiked, with the elements(s) of interest. Laboratory Control Samples are analyzed at a
minimum of 1 per batch of 20 or fewer samples or preparation method. Results of the
LCS are expressed in terms of percent recovery and are used to determine batch
acceptance.
11.1.3 An LCS Duplicate may be analyzed to evaluate laboratory precision. The LCSD must
also meet the criteria for the LCS. The Relative Percent Difference (RPD) will be
calculated between the LCS and LCSD.
NOTE: In the event where adequate sample is not supplied by the client to
perform a Matrix Spike/ Matrix Spike Duplicate, the LCS and duplicate can lend
insight on the precision of the analysis.
11.1.4 MS/MSD: Matrix spikes (MS and MSD) are performed to evaluate the effect of the
sample matrix upon analytical methodology. A separate aliquot of sample is spiked with
the element of interest and analyzed with the sample.
11.1.4.1 MS and MSD are performed at a minimum frequency of one pair in 20
samples per matrix type per sample preparation.
11.1.4.2 MS and MSD are done more frequently where regulations and client
requests require.
11.1.4.3 The RPD between the MS and MSD is evaluated.
11.1.4.4 A matrix effect is indicated if the LCS data are within acceptance criteria, but
the matrix spike data exceed the acceptance criteria. Prior to calculating
recovery, the parent sample concentration (results <Reporting MDL = 0) is
subtracted from the spike aliquot concentrations.
11.1.5 DUP — A Laboratory Duplicate is performed by client request; and is performed on a
second aliquot of sample to evaluate consistency in the analytical procedure and in the
sample matrix.
11.1.6 SRM — A Standard Reference Material is typically prepared and analyzed upon client
request. It is a sample of known concentration chosen to resemble the matrix being
analyzed.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.

11.2 Method Performance
11.2.1 Detection Limits
11.2.1.1 Detection limits (DL) and limits of quantitation (LOQ) are established at initial
method setup and verified on an on-going basis thereafter. Refer to Pace
ENV corporate SOP ENV-SOP-CORQ-0011 Method Validation and
Instrument Verification and to the laboratory's SOP ENV-SOP-GBAY-0106
Determination of LOD and LOQ (most recent revision or replacement) for
these procedures.
11.2.1.2 The LOD and LOQ are always adjusted to account for actual amounts used
and for dilution.
11.2.1.3 Current LOD and LOQ can be found in the Laboratory Information
Management System (LIMS) - EpicPro.
11.2.1.4 Level of Detection (LOD): The LOD is determined by the 40CFR Part 136B
MDL study. Once the 40CFR Part 136B MDL is determined it may be
elevated if deemed unrealistic as demonstrated using method blank
evaluations.
11.2.2 Periodic performance evaluation (PE) samples are analyzed per ENV-SOP-
GBAY-0107, PE/PT Program (current revision or replacement), to
demonstrate continuing competence. All results are stored in the QA office.
At a minimum, these are performed twice a year for the aqueous and soil
matrices.
11.3 Analyst Qualifications and Training
Employees that perform any step of this procedure must have a completed Read and
Acknowledgment Statement for this version of the SOP in their training record. In addition, prior
to unsupervised (independent) work on any client sample, analysts that prepare or analyze
samples must have successful initial demonstration of capability (IDOL) and must successfully
demonstrate on-going proficiency on an annual basis. Successful means the initial and on-going
DOC met criteria, documentation of the DOC is complete, and the DOC record is in the
employee's training file. Refer to laboratory SOP ENV-SOP-GBAY-0094 Orientation and
Training Procedures (most recent revision or replacement)for more information.
12.0 DATA REVIEW AND CORRECTIVE ACTION
12.1 Data Review
Pace's data review process includes a series of checks performed at different stages of the
analytical process by different people to ensure that SOPs were followed, the analytical record is
complete and properly documented, proper corrective actions were taken for QC failure and
other nonconformance(s), and that test results are reported with proper qualification.
The review steps and checks that occur as employees' complete tasks and review their own
work are called primary review.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

An experienced peer or supervisor also reviews all data and results. Secondary review is
performed to verify SOPs were followed, that calibration, instrument performance, and QC
criteria were met and/or proper corrective actions were taken, qualitative ID and quantitative
measurement is accurate, all manual integrations are justified and documented in accordance
with the Pace ENV's SOP for manual integration, calculations are correct, the analytical record is
complete and traceable, and that results are properly qualified.
Reporting performs a third-level review, called a completeness check, or project management
staff to verify the data report is not missing information and project specifications were met.
Refer to laboratory SOP ENV-SOP-GBAY-0120 Data Review and Final Report Processes (most
recent revision or replacement) for specific instructions and requirements for each step of the
data review process.
Draw a single-line strikethrough for any unacceptable or changed data, then DATE and INITIAL
and provide a written explanation of the reason for the change.
Data are validated and peer reviewed by lab personnel using a batch cover sheet attached to
the raw data and filed.
Any discrepancies and issues occurring with each batch should be included on the cover sheet
to be incorporated into a narrative.
12.2 Corrective Action
Corrective action is expected any time QC or sample results are not within acceptance criteria.
If corrective action is not taken or was not successful, the decision/outcome must be
documented in the analytical record. The primary analyst has primary responsibility for taking
corrective action when QA/QC criteria are not met. Secondary data reviewers must verify that
appropriate action was taken and/or that results reported with QC failure are properly qualified.

1. If not<LOQ,verify by second analysis. If second analysis confirms contamination for target analyte at or greater than
the LOQ, re-digest sample batch and batch QC provided sufficient sample volume remains. If insufficient sample
volume remains,consult with project manager and client on how to proceed. For MB detections greater than or equal
to the LOD, but less than the LOQ;qualify applicable sample results.For negative measurements more negative than
the LOD,applicable data is given the following data qualifier: "Analyte was measured in the associated method blank
at a concentration of-#.#units."
*For positive MB failures,samples that are non-detection need not be qualified. In addition,samples that are greater
than 10 times the MB detection need not be qualified.
*For negative MB failures samples that are greater than 10 times the MB detection need not be qualified.
2. Verify failure by second analysis. If second analysis confirms LCS(LCSD)failure,re-digest sample batch and batch
QC provided sufficient sample volume remains. If insufficient sample volume remains,consult with project manager
and client on how to proceed.

3. If the parent,MS,or MSD is greater than the reportable linear dynamic range,dilute and reanalyze the parent,MS,and
MSD. If the concentration of the spike is less than 25%of the concentration of the parent,the MS and MSD recoveries
are not evaluated. Any failures resulting from this are qualified appropriately. If the concentration of the spike is
greater than 25%of the concentration of the parent,appropriately qualify the parent sample if either the MS and/or
MSD fail accuracy. If the MS and MSD fail precision control limits flag the parent with the appropriate precision data
qualifier.
4. If the DUP fails precision control limits flag the parent with the appropriate precision data qualifier
5. Outside of client specific criteria,the SRM is digested and analyzed only to demonstrate analyte recovery in a standard
reference material. When the recovery is outside the lab generated statistical limits,the element that failed recovery
will be flagged in the samples for the element that failed.Client specific action may also exist. A specific SRM may also
be requested by the client and with the lack of statistical evaluation of an SRM the default calculations of the existing
SRM will be used due to software limitations.
1 13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT
Pace proactively seeks ways to minimize waste generated during our work processes. Some
examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent
capture, use of reusable cycletainers for solvent management, and real-time purchasing.
The EPA requires that laboratory waste management practice to be conducted consistent with all
applicable federal and state laws and regulations. Excess reagents, samples and method process
wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's
Chemical Hygiene Plan/Safety Manual.
For further information on waste management, consult ENV-SOP-GBAY-0125 Waste Handling and
Management(most recent revision or replacement).
14.0 MODIFICATIONS
A modification is a change to a reference test method made by the laboratory. For example, changes
in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or
extraction times, instrument runtimes, etc. are all examples of modifications. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification for the
conditions under which the procedures in test method SOPs may be modified and for the procedure
and document requirements.
14.1 The elements listed in the scope as reportable from analysis of this digest is more extensive
that those listed in SW846 3050B Rev.2 1996. All elements reported from this digestion
procedure have passed the necessary method performance criteria. This includes MDL, IDOC,
CDOC, and double-blind performance samples.
14.2 SW846 3050B Rev.2 1996 section 4.8 describes the Heating source as Adjustable and able to
maintain a temperature of 90-95°C. The lab follows the temperature criteria in the Procedure
section 7.2 of 95°C±5°C.
14.3 Digestion occurs in 50 mL digestion tubes. These offer more refluxing action than a beaker
even when uncovered. Digestion occurs with a ribbed watch glass. This allows for added
refluxing while still allowing volume reduction. This is why the procedure uses the time limits
instead of the volume reductions.

14.4 The sample is not dried, ground, and sieved prior to digestion. The sample aliquot has been
adjusted to use 0.500 — 0.575 g in place of 1.0 g. All standards and reagents have been
reduced to ensure that the ratios are still consistent with the procedure.
14.5 If a client fails to provide sufficient volume for the method required Matrix Spike/Matrix Spike
Duplicate (MS/MSD), the laboratory will analyze a Laboratory Control Spike Duplicate to
demonstrate precision. The analytical batch will be qualified with the "M5"data qualifier.
14.6 SW846 3050B Rev.2 1996 section 6.3 describes storage as: Non-aqueous samples should be
refrigerated upon receipt and analyzed as soon as possible. No target temperature or range is
specified. The lab practice is to have thermal preservation at 5.6°C. This is based on 40CFR
Part 136, page 29808, footnote 18. Chapter Three Rev. 4 2007 TABLE 3-2 while not providing
a temperature for most metals, does provide a storage temperature for Hg and Hexavalent Cr
in solids of .6°C.
14.7 SW846 3050B Rev.2 1996 was written targeting a wet sample amount of 2.0 g. The lab targets
0.50 g of sample. The acid and peroxide reagent volumes used have been adjusted to the
maximum amount used in the method resulting in a final acid matrix of 10% HNO3 and 5% HCI.
This is a very high acid matrix but provides an aggressive digestion while maintaining
consistent acid matrix that is required for analysis. This also keeps the acid matrix consistent
with batch QC and method QC such as LOD studies.
14.8 SW846 3050B Rev.2 1996 Section 7.2 describes the HNO3 addition being done in multiple
steps. First a 1:1 addition followed by subsequent additions of concentrated HNO3. The lab
SOP is to add all of the HNO3 in a single step but maintain the amount of acid digesting the
sample during the 2-hour digest in this section. Samples that are visibly high organic material or
continue to give off brown fumes at the end of the Section 7.2 2-hour heating period will be re-
set with a lower sample volume that is more applicable to the acid amounts being used.
14.9 SW846 3050B Rev.2 1996 section 7.5 and 7.5.2 both have the final step in the digestion
process as filtering. The lab will centrifuge the samples to eliminate/minimize and undissolved
solids present after digestion. This reduces the possibility of increasing the background for
target elements. There are only a few instances where there is any solid or sediment remaining
after the digestion is complete.
15.0 RESPONSIBILITIES
Pace ENV employees that perform any part this procedure in their work activities must have a signed

1.0 SCOPE AND APPLICATION
This standard operating procedure (SOP) describes the laboratory procedure for homogenizing soil,
liquid, and biota samples to obtain a representative sample aliquot used for analysis or composite.
This procedure is restricted to use by, or under the supervision of, technicians experienced in the
preparation of samples.
2.0 SUMMARY OF METHOD
Solid, liquid, or biological samples are thoroughly mixed or blended to ensure that any aliquots taken
are representative of the sample as a whole. The samples are mixed in either their original containers
or, in the event that original container does not allow for adequate mixing, transferred to an inert
container for thorough homogenization.
Necropsy and/or filleting of whole-body animals may be performed to isolate the individual organs or
portions of the specimen to be homogenized and utilized for analysis.
This SOP involves instruction to chop, grind, and blend plant materials, biological tissue, sediment and
synthetic materials into a homogenized sample compatible with preparation of semi volatile organic
extracts and metals digestates.
Analysts must make reasonable judgments when sub-sampling materials in order to obtain a
homogenous, representative aliquot of the material. Because of the nature of environmental samples,
the analyst may have to treat samples on a case-by-case basis ensuring that all aspects of the
analytical method are performed. In the event that the analyst cannot reasonably determine what
constitutes a representative sample, the project manager or supervisor must be involved so that the
client can help ensure an appropriate representative aliquot is utilized.
3.0 INTERFERENCES
Metallic Devices—Samples to be analyzed for metal constituents must not be homogenized using any
metallic mixing devices or containers as it may result in contamination of the sample with a variety of
metals. Use only glass, plastic or ceramic materials when working with these sample types. This may
not be applicable for tissue samples since metallic devices (blenders, etc.) may be necessary for
grinding and chopping prior to sample homogenization.
Plastic Devices — Samples to be analyzed for organic constituents must not be homogenized using
any plastic mixing devices or containers as it may result in both positive and negative interferences.
Use only glass and ceramic devices when working with these sample types. Metal instruments may
also be used if analysis for metals is not required from the same sample
Solvents, reagents, glassware, and other sample processing hardware may yield discrete artifacts
and/or elevated baselines causing misinterpretation of the analytical results. All these materials must
be free from interferences under the conditions of the analysis, demonstrated by performing method
blanks.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

established. Each chemical should be regarded as a potential health hazard and exposure to these
compounds should be as low as reasonably achievable.
The laboratory maintains documentation of hazard assessments and OSHA regulations regarding the
safe handling of the chemicals specified in each method. Safety data sheets for all hazardous
chemicals are available to all personnel. Employees must abide by the health, safety and
environmental (HSE) policies and procedures specified in this SOP and in the Pace Chemical Hygiene
/ Safety Manual.
Personal protective equipment (PPE) such as safety glasses, gloves, and a laboratory coat must be
worn in designated areas and while handling samples and chemical materials to protect against
physical contact with samples that contain potentially hazardous chemicals and exposure to chemical
materials used in the procedure. Hearing protection should be worn when a blender is in operation, or
during sediment processing when applicable.
Liquid Nitrogen presents additional hazards and may cause cryogenic burns or displace oxygen and
cause rapid suffocation. Use in a well-ventilated area with additional PPE designed for handing these
materials.

6.0 SAMPLE COLLECTION, PRESERVATION, HOLDING TIME, AND STORAGE
The laboratory does not perform sample collection for this procedure. Samples should be collected in
accordance with a sampling plan and procedures appropriate to achieve the regulatory, scientific, and
data quality objectives for the project. The laboratory will record any nonconformance to these
requirements in the laboratory's sample receipt record.
Details concerning sample shipping, preservation and storage can be found in the applicable extraction
and/or analytical SOPs, or as specifically discussed below. Samples must be stored separately from
all standards and reagents. Where possible, samples for trace analysis should be segregated from
highly contaminated samples to avoid cross contamination. Food or drink products must always be
kept away from samples and never stored in the same area with samples.
Biota samples must be kept frozen at .-10°C in their original sample containers until the
homogenization process occurs.
Small rodents must undergo a special procedure to destroy any Hantavirus which may be present.
Refer to the Pace SOP: ENV-SOP-GBAY-0130 Small Rodent Handling and Homogenization (most
recent revision or replacement)for details.
After homogenization, biota samples are kept frozen at 5..-10°C in glass jars sized closest to the
prepared homogenate sample volume. Individual jars of samples are grouped together as appropriate
and stored in a labeled cardboard box within the freezer.
Sediment samples which will be air-dried are received at <_6°C. After the dry and grind procedure is
completed the samples are retained at room temperature.
Synthetic materials may be kept at room temperature.

9.1.2.4 Tare the balance before weighing the NIST certified weights.
9.1.2.5 Use forceps or other means to lift each weight (Do not touch the weights with
fingertips as the residue may artificially adjust the true value of the weights).
Record the date of the calibration check,the true value of the weight,and the actual
measured weight in the logbook. Repeat this procedure for the other certified
weights. If calibration weights differ from the certified weights by more than
specified in the balance calibration logbook, corrective action must be taken (see
Section 9.1.3).
9.1.3 Corrective Action
9.1.3.1 Clean the balance and balance pan. Check the sight level on the balance and
adjust if necessary. Re-tare and reweigh all the certified weights.
9.1.3.2 The internal calibration function (if available) of the balance may be used as a
means of corrective action.
9.1.3.3 Utilize the internal calibration function and diagnostics. Refer to instrument
manual.
9.1.3.4 Contact the QA office for assistance if the balance does not meet the calibration
tolerances.
9.1.3.5 If the above action does not correct the problem, the balance should be taken out
of service and appropriately labeled to avoid improper usage. A service technician
should be contacted.
9.1.3.6 Record any corrective action. Initial and date all entries in the logbook.
9.2 Soil/Solid Sample Homogenization and Sub-sampling
9.2.1 Soil samples that are collected in regulated domestic areas or that are of foreign origin must
be handled in accordance with the Pace SOP: ENV-SOP-GBAY-0121, Regulated Soil
Handling (current revision or replacement).
9.2.2 An analyst examines the sample as received by the laboratory. If standing water is noted on
top of a soil or sediment sample, the water is incorporated into the sample. Any foreign
material, not subject to analysis, must be removed and discarded. This material may include
sticks, leaves, rocks, etc. that are not or cannot be analyzed for that particular procedure.
Any questions related to the nature of the sample should be directed to the Project Manager
(PM). The PM will work with the client to help determine what should be considered foreign
material and how to appropriately qualify the final report, if necessary.
9.2.3 The remaining sample must be homogenized until the point of an even consistency
throughout the entire sample. The easiest option, for non-volatile samples, is to mix the
sample thoroughly in the original container.The sample is considered thoroughly mixed once
all layers, colors, and inconsistencies have been evenly distributed throughout the container.
If additional mixing is still required to get an even consistency, proceed to the next step.
9.2.4 If mixing is difficult in the original container, the analyst should transfer the entire sample into
a larger, clean container and attempt homogenization there. After mixing, return the
homogenized sample to its original container. If homogenization within the container was
successful, this step may be omitted.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.

9.2.5 After mixing thoroughly, the analyst must take out a representative aliquot to use for
preparation or analysis. The analyst must not add or remove minute quantities of sample
from the representative aliquot in an attempt to target a specific final weight. If an analyst
weighs out slightly more than the required weight of sample, they have not adversely
impacted the reporting limit for that sample. If applicable, the analyst should also weigh out
portions of the sample for duplicate or spike analysis at this time so that all aliquots are
approximately equal to each other.When taking aliquots for QC samples, they must be taken
one after the other from the container. A larger amount of sample may not be removed from
the container, mixed further, and then subdivided.
9.2.6 For volatile soil samples, the analyst must attempt homogenization as quickly as possible to
minimize the loss of volatile analytes. This may limit the amount of mixing that can be done
on the sample. The analyst can quickly scrape off the top layer of soil, core down to the
center of the jar, and take an aliquot to acquire a sufficiently representative sample. It should
also be noted that for sample containers that are received for multiple analyses, the volatiles
department must take their aliquot first to minimize loss of volatiles and minimize the chance
of contamination from other departments. Then the sample can be processed for percent
moisture, organic extractions, etc.
9.2.7 Other options for soil homogenization may be employed if requested by a particular client.
When employing a client-requested method, there must be clear documentation in the
preparatory and analytical logbooks stating the method used.
9.3 Water/Liquid Homogenization and Sub-sampling
prior to pouringan aliquot.
9.3.1 Water samples are homogenized by shaking the sample bottle q
This applies to non-volatile analytical methods only. If a sample contains distinct layers —
either liquid or solid —the department supervisor must be consulted to determine the most
appropriate means of homogenizing and splitting the sample.
9.4 Biota (Biological Tissue and Plant) Homogenization:
9.4.1 Clean the work area by wiping the surfaces with a damp cloth. Follow procedure outlined in
SOP: ENV-SOP-GBAY-0143 Labware Cleaning Procedures (current revision or
replacement)to prepare utensils and grinders for use.
9.4.2 Depending on the sample matrix and specific instructions provided by the customer, the
method for ensuring homogeneity may vary. Necropsy and/or filleting of whole-body animals
may be performed to isolate the individual organs or portions of the specimen to be
homogenized and utilized for analysis. The project manager must be contacted for
clarification prior to thawing the samples if there are any questions.
9.4.3 Select a set of samples for processing. Depending on the size of the specimen, remove the
samples from the freezer to allow the specimen to partially thaw. Large specimens typically
need to thaw overnight at room temperature. Small specimens require a shorter amount of
time and may be placed in a refrigerator overnight or thawed at room temperature for 2-3
hours during the day of processing. It is important to make sure that each specimen is not
touching another specimen during the thawing process.
9.4.4 Record the date that the specimens are removed from the freezer to thaw in the Electronic
Biota Homogenization Log.

9.4.5 Pre-label the appropriate sized sample jars with the LIMS numbers. Samples should be
placed in the appropriate sized container dependent upon the sample mass received (40mL,
2oz, 4oz, 9oz). Transport the clean, dry utensils and pre-labeled jars to the countertop work
area.
9.4.6 If the client requires an equipment blank to be processed with the samples, the same
equipment which is used to process the samples must be Deionized Water (DI) rinsed prior
to sample processing. Multiple equipment blanks may be processed with each batch. The
equipment blank must be logged into the LIMs system to report with the sample data.
9.4.7 Once the specimen is adequately thawed, processing may begin. Compare the label on the
specimen with the pre-labeled jar to verify errors have not occurred.
9.4.8 Small fish, such as minnows, are usually collected as composites and will represent a single
composite sample. Large whole fish that require compositing are chopped into cubes and
put through the meat grinder together(refer to 9.4.10) and aliquots of theground tis
sue are
blended with liquid nitrogen (refer to 9.4.11 through 9.4.12).
9.4.9 If the specimen requires filleting prior to homogenization, thaw the fish to the point that it can
be cut into with a sharp clean knife. Skinning or scaling may be necessary prior to filleting
the fish.
9.4.9.1 Skinning: Catfish, bullheads, and other fish may need to be skinned prior to
removing fillets. With a sharp knife slice the skin front to back along the dorsal
side of fish. Make another incision from top to bottom just behind the gills. Hold
the fish head with one hand and grasp an edge of the skin just behind the gill with
pliers. Peel the skin back toward the tail.The skin may also be removed by placing
the fillet with skin attached, skin side down on the cutting board. Remove the fillet
by running knife along the skin between the skin and fillet.
9.4.9.2 Scaling: If scales are to be removed prior to filleting, lay the fish flat on a cutting
board. Grasp the fish with one hand and with the other hand use a scaler to scrape
the scales off the fish. Work the scaler from the tail toward the head. Rinse the
scales and slime from fish prior to filleting.
9.4.9.3 Filleting: Begin with an incision just behind the gills, cutting through the fish from
back to belly. Next, make a clean cut along the dorsal ridge towards the tail. Be
careful not to cut into the gut cavity. After cutting through to the tail, separate the
fillet from the rib cage, peeling the fillet from the carcass with the non-cutting hand.
Pick out any bones. (Rib cage may be removed with the fillet at the client's
request).
9.4.10 Chop large whole-body specimens, plant material, or fillets into 2-3 inch cubes using a sharp
knife and mallet. Smaller samples of limited quantity must be finely ground using the blender
in step 9.4.11.
9.4.11 Grind the cubes in a large commercial meat grinder to coarse texture. Repeat the procedure
a minimum of two times to ensure proper texture.
9.4.12 Transfer the course ground sample to a stainless-steel bowl containing liquid nitrogen. Place
the frozen sample in a blender cup and blend the frozen tissue to a powder consistency.
9.4.13 Transfer the blended sample into the pre-labeled jars.

9.4.16 Periodically, canned tuna or chicken is homogenized using this procedure for use as a quality
control matrix within the laboratory. Each analysis may require a different quality control
matrix, See Section 11 for additional information.
9.4.17 Sample integrity must be maintained throughout the digestion and analytical processes,
therefore samples which were blended with liquid nitrogen should be kept within a freezer at
5-10°C up until the weighing process..
9.5 Sediment Homogenization Procedure (Air Dry-Grind Procedure):
9.5.1 Clean the work area by wiping the surfaces with Methanol. Follow procedure outlined in SOP:

prepare utensils and grinding equipment for use.
9.5.2 Pre-label the appropriate aluminum sample drying tray with 2 removable labels containing
the sample LIMS numbers. Double bagged client samples should be placed behind the
aluminum sample drying tray.The secondary technician must verify the correct bag is placed
behind the correct drying tray.
9.5.3 Remove the interior sample bag and place on top of the exterior client bag. Rip along both
side seams of the interior bag. Place the opened bag inside out slightly above the drying tray
(the sample should fall from the bag into the tray). Ensure no contact occurs between the
outside of the bag and the drying tray. The technician may need to manually transfer the
sediment from the bag to the tray with their gloved hand. Once transferred, the sample is
spread evenly throughout the bottom of the drying tray.
9.5.3.1 An aliquot of the wet sample must be taken in order to complete the dry weight
analysis. Please see SOP: ENV-SOP-GBAY-0004 Measurement of Percent
Moisture in Soils and Solids (current revision or replacement).
9.5.4 The interior sample bag is then placed bag into the exterior client bag. Both bags are then
placed into a 2-gallon plastic bag labeled with the batch workorder number.
9.5.5 Prior to placing samples on the cart for transfer, clean the surface of the sample cart by
sweeping it to remove visible particulates. Then wipe the surfaces clean with Methanol.
9.5.6 Place all drying trays on the clean sample cart and deliver to the drying room. Use Methanol
to wipe the sample racks prior to placing the drying trays in the drying room and record the
drying room temperature, which should not exceed 100 degrees Fahrenheit. Adjust the
temperature as needed and log any changes in the temperature logbook.
9.5.7 Samples should dry for a minimum of 8 hours or until moisture content is less than or equal
to 10%. Once the sediment is adequately dried, processing may begin.

A third-level review, called a completeness check, is performed by reporting or project
management staff to verify the data report is not missing information and project specifications
were met.
Refer to laboratory SOP ENV-SOP-GBAY-0120 Data Review and Final Report Process (current
revision or replacement)for specific instructions and requirements for each step of the data review
process.
12.2 Corrective Action
Corrective action is expected any time QC or sample results are not within acceptance criteria. If
corrective action is not taken or was not successful, the decision/outcome must be documented
in the analytical record. The primary analyst has primary responsibility for taking corrective action
when QA/QC criteria are not met. Secondary data reviewers must verify that appropriate action
was taken and/or that results reported with QC failure are properly qualified. Please see Section
9 for support equipment corrective actions.
12.3 Trouble Shooting
Not applicable to this SOP.
13.0 POLLUTION PREVENTION AND WASTE MANAGEMENT
Pace proactively seeks ways to minimize waste generated during our work processes. Some
examples of pollution prevention include but are not limited to: reduced solvent extraction, solvent
capture, use of reusable cycletainers for solvent management, and real-time purchasing. Additional
information can be found in the Pace's Chemical Hygiene Plan / Safety Manual (current revision or
replacement).
The EPA requires that laboratory waste management practice to be conducted consistent with all
applicable federal and state laws and regulations. Excess reagents, samples and method process
wastes must be characterized and disposed of in an acceptable manner in accordance with Pace's
SOP ENV-SOP-GBAY-0125 Waste Handling and Management(current revision or replacement).
Regulated soil samples are to be handled in accordance with Pace SOP: ENV-SOP-GBAY-0121,
Regulated Soil Handling(current revision or replacement).
14.0 MODIFICATIONS
A modification is a change to a reference test method made by the laboratory. For example, changes
in stoichiometry, technology, quantitation ions, reagent or solvent volumes, reducing digestion or
extraction times, instrument runtimes, etc. are all examples of modifications. Refer to Pace ENV
corporate SOP ENV-SOP-CORQ-0011 Method Validation and Instrument Verification(current revision
or replacement)for the conditions under which the procedures in test method SOPs may be modified
and for the procedure and document requirements.

PROCESS STANDARD OPERATING PROCEDURE
TITLE: Labware Cleaning Procedures
ISSUER: Pace ENV—Green Bay Quality—GBAY
COPYRIGHT©2021 Pace Analytical Services, LLC.
1.0 PURPOSE
This standard operating procedure (SOP) describes the procedure used for cleaning lab glassware
and labware.
2.0 SCOPE AND APPLICATION
Personnel: The policies and procedures contained in this SOP are restricted to use by, or under the
supervision of, analysts experienced in the cleaning of lab glassware and labware.
3.0 SUMMARY
Maintaining contaminant-free glassware and labware is extremely important due to the sensitivity of
most modern instrumentation.
Glassware, labware, and sample processing hardware is washed by hand or in an automatic
dishwasher and then rinsed with the appropriate reagent.
4.0 DEFINITIONS
Refer to the Laboratory Quality Manual for a glossary of common lab terms and definitions.
5.0 HEALTH AND SAFETY
Personal protective equipment (PPE) such as safety glasses, gloves, laboratory coat and wash
apron must be worn in designated areas and while handling chemicals or solvents to protect against
physical contact and exposure.
Concentrated corrosives present additional hazards and are damaging to skin and mucus
membranes. Use these acids in a fume hood whenever possible with additional PPE designed for
handing these materials. If eye or skin contact occurs, flush with large volumes of water. When
working with acids, always add acid to water to prevent violent reactions.
Glassware rinsed with flammable solvents must not be placed in an oven to dry.
Contact your supervisor or local HSE coordinator with questions or concerns regarding safety
protocol or safe handling procedures for this process.
6.0 PROCEDURE
6.1 Inspect Glassware
Inspect all glassware for severe etching, cracks, chips, breaks, and broken joints prior to
cleaning. If broken glassware is discovered, remove form use and place in a glassware
receptacle to be disposed of or repaired.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

6.2 Organic Extraction Glassware
All glassware used in the Organic extraction laboratory should be solvent rinsed with methylene
chloride after use. The rinse will be performed in the organic laboratory, under a fume hood.
Discard used solvent into the appropriate satellite waste container. Dirty glassware should not be
allowed to dry.
Snyder columns are rinsed from the bottom through the top with methylene chloride, paying
special attention to rinse the ground glass joint after use. The rinse will be performed in the
organic laboratory, under a fume hood. Discard used solvent into the appropriate satellite waste
container. After drying, glassware is stored in a dust-free environment.
Wash all other glassware in a solution of one tablespoon of Alconox and warm tap water. The
glassware is submerged as completely as possible in a soaking tub filled with the water detergent
solution. High-level contaminated glassware should be segregated from the other glassware. A
preliminary wash may need to be performed.
Glassware is scrubbed clean with various brushes in warm, soapy water.
After scrubbing, glassware is rinsed thoroughly with clean tap water to removed detergent
residues, followed with a thorough deionized water rinse.
If necessary, soak the rinsed glassware in a basin containing a 10% Sulfuric Acid solution or
equivalent acid and then rinse three times with tap water. Follow with deionized water. NOTE:
Extreme caution is required when preparing, using, neutralizing or disposing of an acid bath.
Appropriate personal protective equipment is always required.
Extraction concentration tubes are baked in the drying oven. Other glassware is inverted, rinsed
with acetone, and air-dried. Glassware rinsed with flammable solvents must not be placed in an
oven to dry. After drying, glassware is stored in a dust-free environment.
All cleaned glassware will be stored in appropriate, labeled drawers or assigned locations until
needed for extractions.
Prior to use in the organic preparation lab, glassware must be rinsed with methylene chloride to
remove any analyte contamination. The rinse will be performed in the organic laboratory, under a
fume hood. Discard used solvent into the appropriate satellite waste container.
Micro-syringe cleaning procedure:
! All micro-syringes must be rinsed a minimum of 3 times using the appropriate solvent
which is being used during the specific step in the extraction or analytical process.
! For matrices which require additional rinses, multiple vials of solvent can be used to
reduce contamination of the rinse solvent.
6.3 Biological Tissue, Plant, and Synthetic Material Glassware/Labware
All labware, utensils and grinders are placed in hot water and one tablespoon of laboratory
detergent concentrate (Alconox, or equivalent). The labware is submerged as completely as
possible in a soaking tub filled with the water detergent solution.
Labware, utensils, and grinders are scrubbed clean with brushes in warm soapy water.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

After scrubbing, labware is rinsed thoroughly with clean tap water. It is then placed in the
automated dishwasher and ruan through the hot rinse cycle one time to remove any detergent
residue. At the conclusion of the final automated rinse cycle, the labware is thoroughly rinsed with
deionized water.
All Iabware, utensils, and grinders are inverted and air dried. If utensils must be used immediately
after washing, they can be methanol rinsed to speed the drying process. After drying, labware is
stored in a dust-free environment covered in aluminum foil.
At the conclusion of the homogenization process, all laboratory countertops within the preparation
area are thoroughly cleaned and disinfected with a 5:1 bleach to water solution.
6.4 Sediment Sample Processing Hardware
Clean the countertop used to process sediment samples thoroughly with Methanol.
All sample processing hardware, including hammer, rolling pin, and scissors, is required to be
thoroughly rinsed with Methanol after each sediment sample is homogenized. Verify the
equipment is free of fine particulate matter by wiping with a clean white paper towel wetted with
methanol. The paper towel should be free of discoloration if the equipment is particulate free.
Replace disposable gloves after every sample.
6.5 Volatile Syringes
Two vials of Purge & Trap Methanol (MeOH) are required to clean micro-syringes. Each micro-
syringe should be rinsed three times with the first vial of Purge & Trap McOH, then three times
with the second vial of Purge &Trap McOH.
To clean 5mL - 50 mL syringes, rinse them three times with cool water (as warm water may lead
to cracking of the glass barrel) and once with RO water by expelling the water with the plunger.
Alternatively, to minimize both ergonomic stress and potential of cracking the syringe barrel, the
barrel can be filled with a minimum of 5 rinses and dumped out before performing the RO water
rinse. The plunger should also be rinsed at least 5 times and RO water rinsed. Note: Extra rinses
may be necessary for syringes in some cases (i.e. strong diesel or samples containing high levels
of late hydrocarbons and chlorinated solvents).
6.6 Wet Chemistry Laboratory Glassware
Use methanol on a paper towel to remove marker writing on glassware. If fumes become a
problem, leave area and allow to ventilate.
Cleaning extreme or stubborn soiling:
! Prepare washtub containing a 2-5% (v/v)solution of Contrad 70 and hot water.
! Soak labware for 2-24 hours.
! Rinse labware 3 times with tap water.
! Wash labware by dishwasher or hand wash procedures.
Dishwasher Operation —The dishwasher cycle finishes with DI rinse.
! Load dishwasher with dishes to be cleaned.
Any printed copy of this SOP and all copies of this SOP outside of Pace are uncontrolled copies.
Uncontrolled copies are not tracked or replaced when new versions are released, or the SOP is made obsolete.
Users of the SOP should verify the copy in possession is the current version of the SOP before use.

Standard Operating Procedure for Small Boat Operations

SOP No.035
Revision: 2

EA Engineering, Science,and Technology,Inc.,PBC March 2019
1. BACKGROUND
The threat from working on or near surface water bodies comes from both chemical hazards
and physical hazards such as drowning. When there is a need for sampling to be conducted
using small boats, EA will provide the necessary safety gear(i.e., life vests,nets, and other
floating devices) and appropriate training.
EA field staff and team members supporting field planning for projects involving small boat
operations should be aware that individual states have different certification, training, and safety
requirements. These requirements should be identified early in project planning and
incorporated into field preparation efforts. The National Association of State Boating Law
Administrators maintains a website (www.nasbla.org)that provides an online reference guide for
state boating laws. In states where boating certification is required, the operator should have
their certification card in their position whenever conducting small boat operations.
1.1 PURPOSE
This Standard Operating Procedure (SOP) establishes the operating requirements for small boats
conducting inland and coastal marine work.
1.2 SCOPE
This SOP applies to the operation of small boats, including launches, motorboats,working
platforms, and skiffs, for inland(rivers, lakes, and bays) and coastal marine work. This SOP
applies to EA personnel operating a small boat or working on a subcontractor-operated small
boat. This SOP covers small boat requirements, work over or near bodies of water,personal
flotation devices (PFDs), lifesaving and safety skiffs, severe weather precautions, and cold
water and drowning hazards. This SOP is mandatory for EA personnel. Subcontractors are
responsible for analyzing the hazards of activities they control and for preparing job hazard
analysis and maintaining equivalent safety requirements.
1.3 DEFINITIONS
Small Boat—Includes dinghies, 1- or 2-man rowboats,up to and including larger vessels
typically up to 30 feet (ft) in length, and work barges.
Float Plan—A written summary of the details of the trip, including route, type of vessel,
persons aboard, and other salient information that may be useful in the event of an emergency.
Job Hazard Analysis—A concise analysis of the specific task considering the body of water,
vessel, unique job requirements, training and experience of crew, and other circumstances as
may be appropriate.

1.4 RESPONSIBILITIES
The Project Health and Safety Officer is responsible for review and approval of small boat
operations as described in the Health and Safety Plan. The Project Health and Safety Officer
provides any necessary safety requirements to the project team. The Project Health and Safety
Officer will review the job hazard analysis prepared by project personnel.
Health and Safety Officer—The Health and Safety Officer is responsible for ensuring the proper
use of small boats at field locations. The Health and Safety Officer ensures that only trained
personnel operate small boats, subcontractors implement safety programs, and that all equipment
is properly maintained. The Onsite Safety Officer is responsible for filing or maintaining a float
plan.
Small Boat Operators—Certified(as appropriate by the state where the project is located) EA
personnel working on small boats will follow this procedure and any applicable health and safety
procedures identified in the Health and Safety Plan and the vessel rules. Small boat operators
will identify any conflicts in procedures or any problems or equipment failures to the Health and
Safety Officer. Small boat operators will demonstrate training, experience, and compliance with
state requirements for operator education and licensing prior to operating any vessel. For larger
bodies of water, or rapidly moving water,knowledge of local conditions shall be obtained prior
to embarkation.
2. SMALL BOAT REQUREMENTS
All small boats used by EA personnel must meet the minimum requirements in the U.S. Army
Corps of Engineers Safety and Health Requirements Manual Engineer Manual (EM) 385-1-1 and
the applicable Occupational Safety and Health Administration or state plan requirements, as well
as meeting applicable U.S. Coast Guard Regulations. These requirements include the following:
• Small boats will meet the minimum flotation requirements of the U.S. Coast Guard, and
must have a certification tag affixed to the hull.
• Small boats will have valid proof of registration.
• The maximum number of passengers and weight that may be safely transported must be
posted on all small boats.
• The number of personnel on the small boat cannot exceed the number of Type I PFDs
onboard.
• Each small boat will have sufficient room freeboard, and stability to safely carry the
allowable number of personnel and cargo.
EUSStandard Operating Procedure for Small Boat Operations

SOP No.035
Revision: 2
Page 3
EA Engineering, Science,and Technology,Inc.,PBC March 2019
• Each small boat shall have an appropriate complement of hand tools onboard to address
boat maintenance and emergency repair.
• Each motored boat measuring less than 26 ft in length will carry a minimum of one
1A-10 BC fire extinguisher; motored boats measuring greater than 26 ft will carry a
minimum of two 1A-10 BC fire extinguishers.
Operators and occupants of small craft will review Federal Requirements and Safety
Tips for Recreational Boats (U.S. Coast Guard 1994)before engaging in work from rafts,
dinghies, canoes,rowboats, or Jon boats.
2.1 WORK OVER OR NEAR WATER
Work over or near water,where the potential exists for personnel to fall in and possibly drown,
will be conducted in accordance with the requirements of applicable Occupational Safety and
Health Administration standards and the U.S. Army Corps of Engineers EM 385-1-1 standards.
This includes work from shore, bridges, work platforms, and vessels. Work within 15 ft of
unobstructed access to water is within the requirements of this section. Personnel will follow the
guidelines listed below except where personnel are protected by continuous guardrails, safety
belts, or nets, or are conducting work along beaches or similar shorelines:
• Personnel will use the buddy system at all times.
• Swimming is prohibited,with the following exceptions: (1) certified divers performing
their duties, and (2)personnel entering water to prevent injury or loss of life.
• All personnel will wear a U.S. Coast Guard-approved PFD of the type able to support an
unconscious person(Type III) continuously. Type I PFDs must be available for all
personnel on the vessel.
• At least one Type IV throwable device (e.g., ring buoy or horseshoe buoy)will be
available on the small boat. Throwable devices should be U.S. Coast Guard-approved
and equipped with 150 ft of 600-pound capacity rope.
• If specified in the Health and Safety Plan, at least one person will provide a dedicated
safety watch/look-out.
2.2 PERSONAL FLOTATION DEVICES
All EA personnel will wear a U.S. Coast Guard-approved, Type III PFD when working over or
near bodies of water. PFDs should meet the following requirements:
• Before and after each use, the PFD will be inspected for defects that would alter its
strength or buoyancy.
Standard Operating Procedure for Small Boat Operations

SOP No.035
Revision: 2
Page 4
Engineering,Science,and Technology, BC
March 2019
EA Eng g, Inc.,,
• All PFDs will be equipped with retro reflective tape.
PFDs need not be donned when working on larger craft(>26 ft)when working within the
boat's cabin. PFDs should be worn at all times when working on smaller craft.
2.3 SAFETY EMERGENCY DRILL
The vessel operator shall provide a list of crew duties for normal operations and emergencies.
Emergencies that will be covered include man-overboard, vessel fire, and vessel emergency.
The vessel operator will provide an orientation and emergency drill. An emergency drill will be
conducted at the start of each task, and monthly thereafter, or as provided for in U.S. Coast
Guard regulations.
2.4 FLOAT PLAN
A float plan provides essential information to enable the U.S. Coast Guard or other emergency
search and rescue teams to initiate a search in the event of personnel not reporting in on
schedule. The vessel operator will file a project-specific daily float plan with the designated on
shore individual and with the project health and safety representative listed in the Health and
Safety Plan. Upon daily completion of on-water work, the vessel operator will check in with the
designated on shore individual. The float plan form is provided in Attachment A.
2.5 EMERGENCY PLAN
The emergency plan should list a main dock and an alternate dock, and provide emergency
medical support contact for each location.
2.6 COMMUNICATIONS
For open water,tidal environments, or industrial waterways, a marine very high frequency
(VHF)radio will be maintained onboard and in operable condition. Mobile telephones can be
substituted for a marine VHF radio at the discretion of the Health and Safety Officer on sites
with minimal boat traffic on inland rivers,ponds, and lakes.
2.7 OCEAN AND NIGHTTIME REQUIREMENTS
These operations require a specialized skillset, experience, and additional training. Contact the
Corporate Health and Safety Officer and Project Health and Safety Officer prior to planning any
work that requires work in open ocean or nighttime operations.
2.8 SEVERE WEATHER PRECAUTIONS
During field operations involving small boats, EA personnel will make provisions for severe
weather conditions in advance. Severe weather includes sudden and locally severe storms,
EAStandard Operating Procedure for Small Boat Operations

SOP No.035
Revision: 2
Page 5
EA Engineering, Science,and Technology,Inc.,PBC March 2019
lightning,high winds, waves, hurricanes, and floods. Before beginning work over water,the
Health and Safety Officer and Small Boat Operators will evaluate and track weather reports and
conditions to ascertain local weather and prevent personnel exposure to severe weather. In the
event that severe weather is encountered,personnel will cease field operations and immediately
return to shore. Designation of multiple sheltering locations should be planned in advance.
2.9 COLD WATER AND DROWNING HAZARDS
EA personnel conducting field operations with a small boat may be exposed to cold water and
drowning hazards. When water temperature is below 45 degrees Fahrenheit, hypothermia is a
serious hazard. A person can lose feeling in extremities within 5 minutes, loss of consciousness
in 10 minutes, and loss of life in 20 minutes. Under no circumstances will EA personnel enter
the water from a small boat unless conducting diving operations or performing a rescue.
Symptoms of hypothermia are discussed
ymp yp d s ussed during standard first aid training and in the EA Health
and Safety Program Plan. If a person who has fallen into the water displays symptoms of
hypothermia, he or she should be treated immediately and the field operations canceled. Under
no circumstances should the victim be given hot liquids, since they can accelerate shock. Drinks
no wanner than body temperature are acceptable. If symptoms are severe and rapid evacuation
is not possible, remove the victim's wet clothing and cover the victim with a blanket. Continue
to treat the victim for shock.
When a high risk of cold water and drowning hazards exists, all field staff members should be
familiar with cold water survival techniques. If a team member falls into the water, he or she
should not remove any clothing in the water because all clothing will provide insulation.
Although clothing creates added drag while swimming, the added insulation of the clothing
outweighs the disadvantage of the additional drag.
If a team member falls into the water, another team member should try to reach the person
in the water with an oar,paddle,pole, or similar object. The victim should try to grab the
extended item. If the victim is unconscious, the rescuer should try to hook the victim's PFD,
clothing, or hair and pull him or her toward the boat. Once the victim is retrieved, the other
team members should begin any necessary emergency medical procedures. A minimum of one
team member on the vessel should be certified for cardiopulmonary resuscitation/first aid. If no
emergency medical procedures are necessary, the victim should change into dry clothing.
An additional consideration that must be evaluated related to small boat operations associated
with cold weather conditions is the presence of ice. Immediately prior to launch, ice and
potential icing conditions should be assessed. Boat ramps can become very hazardous in icy
conditions and can cause trucks to lose tracking when launching or removing a boat from the
water.

2.10 JOB HAZARD ANALYSIS
The requirements for preparing a job hazard analysis apply specifically to all on-water
operations. Attachment B provides a sample job hazard analysis; however, an actual job hazard
analysis will consider the specific task including the body of water,vessel type,unique job
requirements, training and experience of crew, and other circumstances such as tides,weather,
water temperature, access of rescue craft, and other factors as may be appropriate. Job hazard
analyses must be prepared specifically for each task and crew in accordance with the U.S. Army
Corps of Engineers Safety and Health Requirements Manual EM 385-1-1.

1. SCOPE AND APPLICATION
The purpose of this Standard Operating Procedure is to delineate protocols for the collection of
fish samples for tissue analysis.
2. MATERIALS
The primary instrument for collecting fish in freshwater environments is electrofishing, either
by boat or by wading in a stream/shallow river. A Smith-Root VVP-15 or similar model
electrofishing unit will be employed at deep water locations using an 18-foot(ft)boat platform.
In shallow depths where a smaller electrofishing unit is necessary, a Smith-Root 1.5-kilovolt
ampere unit mounted in a 14-ft Jon boat will be used. For streams and small rivers where
wading is possible, a Smith-Root or similar model portable backpack electrofishing unit will be
utilized. The electrofishing units will be used in the pulsed direct current mode.
Other equipment used in fish collection studies may include:
• Hand nets (dip nets)
• 5-gallon buckets
• A Global Positioning System unit(for marking collection areas or navigating to
previously sampled locations)
• Glass or polytetrafluoroethylene(PTFE) cutting board
• Stainless-steel filet knife
• Aluminum foil
• Large zip-lock bags
• Indelible markers
• Sample labels

• Copy of the Scientific Collector's Permit
• Location map
• Field logbook and datasheets
• Chain-of-custody (COC) form(s)
• Coolers and ice
• Live well and aerator
• Appropriate weight measurement device
• Appropriate length measuring device
• Scissors and pliers to cut fish spines
• Digital camera
• Deionized water
• Nitric acid solution.
Additional gear may be employed if electrofishing is inappropriate for use at the project site and
to supplement the electrofishing method. These may include seine net, gill net, Fyke net,jug
line, eel traps,minnow traps, crab traps, or rod and reel.
In marine environments (salt water with high conductivity), electrofishing is not used since the
conductivity carries the electric current around the fish. In marine fish tissue surveys, other
equipment is employed. This may include gill nets, seine nets, trawl nets,jug lines, or rod and
reels.
3. COLLECTION PROCEDURE
The purpose of this section is to provide a broad description of selected methods of collection
so that there are several routes by which to obtain field samples.
The primary method for fish collections will be boat electrofishing. This method is effective at
collecting all trophic levels of fish to be analyzed at each of the selected locations, while
reducing negative impacts to non-targeted fauna. The boat operator will move the boat slowly
through likely fish habitat, including areas providing cover(e.g., snags, submerged aquatic
vegetation, and other forms of structure). The primary collector stands on the bow of the boat
EAStandard Operating Procedure for Collection of Fish Tissue for Chemical Analysis

and initiates the electric current using a"deadman's" switch foot peddle and collects stunned fish
using a long-handled dip net. The duration of the current can be adjusted by the collector based
on the number of stunned fish observed and the rate at which they recover and escape. The
second collector will stand in the mid-section of the boat using a dip net to capture fish drifting
past the boat. Alternatively, if space allows, two collectors will stand side-by-side on the bow,
collecting both fish off the bow and the sides of the vessel, with each collector focusing on the
side they are nearest. One collector will be designated to operate the "deadman's" switch foot
peddle prior to the sampling effort.
In order to assess the relative availability of target species versus the need to consider targets of
opportunity, all stunned fish captured will be placed in live wells; the water will be refreshed
periodically to minimize stress to the captured fish resulting from depletion of dissolved oxygen.
At such a point when it becomes clear that target species are available in adequate numbers to
meet the sample quotas, only target species will be captured and held.
When sampling marine waters and other circumstances for which electrofishing is inappropriate,
traps should be checked regularly and non-target fish released. Target fish should be processed
as necessary (fileting and compositing) and placed in coolers, as soon as possible.
During project planning and field sampling documentation (work plans and quality assurance
project plans), it is important to include all potential methods for catching fish that may be used
for the project. In addition, it is common for targeted species to not be present; consequently,
alternative species should be considered during project planning.
4. COLLECTION PERMIT
Permission is required to conduct these studies, and approval must be granted by the regulatory
authority within the state where the study will be conducted. A Scientific Collector's Permit
must be applied for and the study plan approved by the proper agency or agencies prior to
initiating the study. Be sure to apply for the Scientific Collector's Permit ahead of time to allow
the paperwork to be completed and provided. Under no circumstances, should fish collections be
performed without the required Scientific Collector's Permit. Copies of Scientific Collector's
Permits should be carried with the field crew to provide documented evidence as needed to
authorities.
5. DOCUMENTING SAMPLE LOCATION
The location of samples will be noted in a field logbook and on a map used in the field.
Coordinates will be obtained using a hand-held Global Positioning System and recorded in
the field logbook. Fish collection efforts are conducted over a general area that is sampled;
therefore, specific coordinates collected will relate to the approximate center point of the
collection effort for a specific location. The location should also be marked on a field map

relative to a position on the shoreline. Significant events, observations, and measurements
during the field investigation will also be recorded in the field logbook.
Field logbook entries will include, at a minimum, the following information:
• Author, date and time of entry(use 24-hour military time), and physical/environmental
conditions during the field activity.
• Names and titles of field crew.
• Names and titles of any site visitors.
• Type of sampling activity.
• Location of sampling activity, sampling time, water temperature, dissolved oxygen,
conductivity, and pH.
• Field observations.
• For each submitted fish sample, the number of fish included, and the species name,
weight, and size of each fillet,whole body, or other appropriate measures included in
the composite analytical sample. Also, whole body characteristics should be included
for each fish fillet collected.
• Any deformities (lesions, sores, etc.) observed on any of the fish.
• Any photos taken and their reference numbers
• Analyses to be performed on these fish samples.
• If any page is not completely filled in, a line drawn through the unused portion and
initialed by the person keeping the log.
• Decontamination procedures.
• Documentation of any deviations from the Field Sampling Plan.
• Unusual incidents or accidents.
Original data recorded in these field logbooks, field data sheets, sample labels, or COCs should
be made using indelible dark blue or black ink. None of these documents will be destroyed or
discarded, even if they are illegible or contain inaccuracies.

If an error is made on any of these documents, the error will be corrected by crossing a line
through the error and entering the correct information, then initialing and dating the cross-out.
Any subsequent error discovered on one of these documents will be corrected by the person who
made the entry, and will be initialed and dated as appropriate.
Photographs will be taken of field activities. Each photograph will have an entry in the field
logbook indicating the location, date, and time it was taken. Photographs of activities such as
biota sampling locations will be taken to record activities.
6. FIELD HANDLING AND DATA COLLECTION
Individual fish used for a sample will be measured for total length and weighed. Each fish will
be rinsed with water to remove any sediment or detritus and inspected for anomalies and the
information recorded in the field logbook and representative datasheet if applicable. Targeted
species that will be used for sample preparation will be evaluated for their suitability as part of
a composite sample.
Sample preparation will be specific to the laboratory conducting the tissue analysis. Selected
specimens will be either wrapped in aluminum foil then bagged in plastic bags or directly bagged
in plastic bags. All samples will be labeled with sample number, location, number of fish in
composite, date, taxa, initials of the sampling crew, and disposition(i.e., fillet or whole body)
and placed in a cooler of ice. Each sample will be provided with an internal label that is in the
bag with the specimen and an external label on the bag containing the sample. At the end of
each day, fish will be processed (be it filleted or whole body), composited, and either frozen and
held for shipping at a later date or shipped to the laboratory immediately.
A composite sample will consist of a minimum of 3 fish collected at a specific location and of
a specific trophic level (predator,bottom feeder). The number of specimens included in the
composite should satisfy the tissue mass requirement by the analytical laboratory. All
information regarding sample contents will be recorded in the field logbook and a representative
datasheet.
7. SAMPLE HANDLING
If the project study plan specifies fillets, then samples of target species will be cut either by the
field crew at the end of each day or, if preferred, by the analytical laboratory. This decision will
be dictated by the laboratory prior to the initiation of the field sampling effort. Fillet samples
will be prepared according to the EPA Guidance for Assessing Chemical Contamination Data for
Use in Fish Advisories Volume 1 Fish Sampling and Analysis—Third Edition(November) (EPA
823-B-00-007) (EPA 2000).
Fish should be scaled prior to being filleted; do not remove the skin. To scale fish,place on a
clean glass or PTFE cutting board. Run the edge of the knife blade from the tail toward the head
1EGStandard Operating Procedure for Collection of Fish Tissue for Chemical Analysis

Revision: 1

to scrape off the scales. Cross-contamination can be avoided by rinsing the cutting board and
knife with acid and distilled water. After scaling, rinse the fish with distilled water and place on
a clean cutting board; the fish is then ready for filleting.
Prior to filleting,hands should be washed and rinsed with distilled water and, if gloves are worn,
they should be talc-free and dust-free. Place fish on a clean glass or PTFE cutting board. Care
should be taken to avoid puncturing internal organs because the fillet tissue can become
contaminated from materials released from the organs. If organs are punctured, the fillet tissue
should be rinsed in contaminant-free deionized distilled water and blotted dry.
Fillets should be cut as follows:
• Make a diagonal cut from the base of the cranium following just behind the gill to the
ventral side just behind the pectoral fm.
• Remove the flesh and ribcage from one side of the fish by cutting from the cranium along
the spine and dorsal rays to the caudal fin.
• The skin should be scored prior to homogenizing the entire fillet.
Fillets should be weighed and recorded to the nearest gram. Sample weights will vary according
to project specifications. Residue from the filleting process should be placed in a double-bagged
plastic trash bag and disposed of properly in a dumpster.
8. COMPOSITING TECHNIQUES AND RECOMMENDATIONS
The sample weight/size is project specific. Following is the compositing technique assuming
a 200-gram(0.44-pound) sample weight. The composited sample should contain, at a minimum,
three individuals of similar size. The number and length of individuals or fillets should be
recorded for each composite sample.
All samples in a composite sample should be similar in length such that the product of the length
of the smallest individual divided by the length of the largest individual multiplied by 100 is
greater than or equal to 75 percent:
Minimum Size x 100 = >_ 75%
Maximum Size
This will ensure similarities in age and exposure to the area in question(EPA 2000).

9. SAMPLE CONTAINERS AND PRESERVATION TECHNIQUES
Composite fillet samples will be individually labeled and placed in the appropriate container; the
container type will be dictated by the analytical laboratory and/or client scope of work. Whole-
body fish composites will be individually labeled with both a label in the bag and an external
label, wrapped in aluminum foil, and double-bagged in clean plastic, zip-lock airtight bags as
preferred by the analytical laboratory and/or client scope of work. Individual sample labels will
contain the following information:
• Project number
• Sample location and station number
• Species (genus and specific epithet)
• Individual sample number
• Total number of individuals in composite
• Sampler's initials
• Date and time of sample processing.
For shipping to the analytical laboratory, a 3-inch layer of inert cushioning material (bubble
wrap) will be placed on the bottom of a waterproof cooler or ice chest. The samples will then be
placed on the cushioning material and surrounded with ice double bagged in plastic bags to
maintain a temperature of 4 degrees Celsius or lower. Review shipping and packing
requirements with the receiving laboratory prior to sample collection to identify project- or
analysis-specific requirements (e.g., use of dry ice).
A temperature blank should be included in each cooler. COC records will be completed at the
time of sample preparation and compositing. All samples will be sent by overnight express to
the laboratory or hand-delivered the day after collection. The COC must be signed showing any
sample transfer and placed in a plastic bag taped to the inside lid of the cooler. Each cooler
should have a COC for those samples contained in that cooler. The cooler/ice chest drain should
be taped shut. Appropriate shipping labels are attached to the top of the cooler and"This Side
Up" labels placed on all four sides of the cooler/ice chest. Lastly"Fragile" labels should be
placed on at least two locations of the cooler/ice chest. Be aware of any weight limitations that a
shipper may have for shipping the cooler/ice chests.

1. INTRODUCTION
This field manual describes basic concepts and safety issues of electrofishing systems.
The information in this document should also increase understanding of how the systems
work and how to properly operate them to increase their effectiveness and reduce
unnecessary harm to fish.
1

2. BASIC CONCEPTS
2.1 Electrofishing
In many cases, the most effective means of collecting fish for scientific purposes.
Electrical current is placed in the water to immobilize fish, allowing them to be collected
with dip-nets. It involves the use of either AC (alternating current) or DC (direct current)
to immobilize fish for capture. These two types of current have very different effects on
fish. The choice of current to use is dependent on the type of study being performed and
the importance of returning healthy fish to the water.
2.2 AC & DC Current
AC current typically has the most violent effect on fish. Once in the electrical field a fish
will immediately"take a posture transverse to the current in such a way as to receive a
minimum of voltage" (Smith-Root). This action is called oscillotaxis. Fish will be
immobilized quickly and the effect will last longer than that of DC current. Great care
must be taken in the collection of fish in this manner. If AC current is applied for too
long of a period, the fish may not recover. Another drawback to this type of collection is
that since fish usually become immobilized almost immediately when hit by the current,
some may be missed because they are shocked while several feet below the surface and
out of sight.
DC current, in most cases, will be the preferred method of collection. Fish react in three
ways to DC current. First, they line up with the direction of the electrical current, then
swim toward the anode (positive electrode). This reaction is called galvanotaxis.
Finally,when fish near the anode they are stunned, roll belly up, and collection becomes
possible. The effects of DC current do not last as long as of AC current. When the
power is turned off the fish recover quickly. Mortality is far more limited than with the
use of AC. This, along with the fact that fish actually swim to the anode, makes DC
current the more effective means of electrofishing.
2.3 Control Box
AC or DC current can be selected with electrofishing control boxes. In addition to
controlling the type of current, a control box allows adjustments to how the current acts.
Most equipment will allow you to select for standard or pulsed output and to vary the
pulse width and frequency of pulses, which allows for more efficient collections and
limits the risk and stress to fish.
The control box also allows selection of voltage output. Depending on the electrofishing
system used(i.e., Smith-Root), this selector should be positioned at the lowest possible
setting that allows 5-10 amps to be obtained by adjusting the pulse width and rate or a
minimum of 190 volts.
2

Pulsed output means that the electrical current going from the system into the water
comes in pulses or waves. When the pulse rate is low and the width of the field is
narrow, less current is required to collect fish. This results in less stress to fish. Since
conductivity of water(the ease with which an electrical charge passes through it) varies,
it is necessary to have the ability to adjust the pulse rate and width for optimum collection
with minimum harm to the fish being collected.
2.4 Conductivity
Electrofishing works by passing electrical current through a fishes body causing the

fish's body and thus,the effectiveness of electrofishing. If the conductivity of the fish's
body is equal to or slightly above the conductivity of the surrounding water, the
electricity will choose the path of least resistance and pass through the fish. The greater
the conductivity of the fish's body in relation to the surrounding water,the greater the
effect of the electricity on the fish. The conductivity of fish flesh differs among species.

time, scaled fish maynot succumb to the current until theyactually pass within
the same
a few feet of the anode. Also, due to increased surface area, larger fish,particularly large
and deep-bodied fish, tend to receive a larger charge of electricity than do smaller fish.
Another factor that influences the effectiveness of electroshocking is the conductivity of
the water. Pure distilled water will actually act as an insulator in an electrical current.
This is because there are few electrolytes or dissolved solids to conduct the electricity. It
would take a great deal of current to pass through this type of water. Conversely,the
water of a typical lake or river may be very high in dissolved solids. This water will
readily conduct very low amounts of current. In all cases, the conductivity of the water
must be equal to or below the conductivity of the fishes body for electrofishing to be
effective. It is not effective to shock in salt electrolyte water because it is solution.
The conductivity of the water is so much higher than that of a fish that an electrical
current will find that the path of least resistance is actually around the fish rather than
through it.
Conductivity of the water being surveyed should always be checked before attempting
electrofishing. If it is very low(<50 µS/cm) or extremely high (>4500 µS/cm), a
different type of collection should be considered. When backpack,pram(tow barge), or
long line (bank unit) shocking small streams, it may actually be possible to increase the
conductivity of the water by placing a block of salt upstream of the study area several
hours before beginning your survey. This however, should only be considered in
controlled conditions.
2.5 Types of Equipment
There are several types of electrofishing equipment available. EA typically uses boat,
backpack,pram or long line units. These units differ in the type of power source used
and in their application.
3

Boat electrofishing is utilized where water depths and characteristics make maneuvering
the boat possible. EA primarily uses this type of electroshocking in lakes, reservoirs, and
navigable rivers. Boat electrofishing usually involves the use of a large generator(i.e.,
5000 watt+) as an electrical power source. The generator sends electricity through a
control box, which allows the operator to adjust the type of electrical current being placed
in the water.
Pram, long line, and backpack electrofishing are designed for use in areas where boat
electrofishing may not be possible or practical. Backpack units consist of a power source
(a small generator or battery) and a control box mounted on a backpack frame. A hand
held positive electrode (anode) and trail behind negative electrode (cathode) are utilized
by the operator to place electrical current in the water. The user is protected from the
current by rubber waders and electrical gloves.
Pram shocking involves the use of a power source and electroshocking unit placed in a
barge or small boat. Like backpack electrofishing, the operator utilizes a hand held anode
and trail behind cathode to place current in the water. The methods differ in that the
operator is not required to carry the power source.
Long line electrofishing involves the use of a power source and electroshocking unit
deployed on the bank. Like the other wadeable methods, the operator utilizes a hand held
anode. However, the cathode is stationary, typically deployed in the middle of an
electrofishing zone near the control box and power source, to place current in the water.
As with the pram unit, the operator is not required to carry the power source and control
box. Cables with up to 100m long allow mobility over a large section of water.
In all types of electrofishing, current is passed through the water between a positive
electrode (anode) and a negative electrode (cathode). EA typically uses a boom mounted
anode and the boat hull as a cathode when boat electrofishing. You may however, see
different arrangements. In backpack electrofishing the anode is a hand-held probe or
dipnet and the cathode is a trail behind cable. In pram shocking, the cathode may be the
hull of either the barge or boat carrying the equipment, and in long line shocking the
cathode is a cable or plate deployed from a bank-mounted power source.
2.6 Equipment Operation
A typical boat shocking survey would be made up of two or three team members. The
team leader or an experienced technician will operate the boat and shocking system while
the other crewmember(s)will stand at a bow mounted railing and collect fish with
properly insulated dip nets. Either the operator or the netter will operate a foot switch
which will immediately cut the power output if released. This is a very important safety
feature and no electroshocking boat should be operated without a safety switch.
Backpack,pram, and long line shocking are slightly more hazardous than boat shocking
because of the user's position in the water with the electrical charge. Field training
4

sessions should be completed with an experienced wadeable electrofishing operator
before attempting this technique. Basically, a wadeable system is a miniaturized version
of the boat electrofishing system. At least two operators are required for backpack and
pram electrofishing while three operators are preferable when using the long line method.
For backpack and pram shocking,the operator handles the anode, which consists of a just
a probe or a combination of probe and dipnet, depending on conditions. The second
person monitors the equipment while assisting with the collection, transfer, and care of
fish. For long line electrofishing, a third person typically maintains the cable and
manages the live car.
The operator wades in an upstream direction through the water sweeping the anode 2-3
feet ahead. A thumb switch on the handle of the probe serves the same safety function as
the foot switch on the boat. With a net probe, when a fish is shocked, the operator
collects it with the dipnet,releases (i.e., turns off)the switch on the handle and places the
fish in a bucket, live-well, or live car. If the anode is not operated with an attached net,
the second person will closely follow the operator and anode with a dipnet to collect fish.
When pram shocking, special attention should be paid by all crewmembers to the size of
the electrical field. If the cathode is mounted on a barge,boat, or bank the electrical field
will reach from that point to the anode held by the operator. When backpack shocking,
this field is concentrated only around two probes.

3. SAFETY
3.1 Safety Awareness
When performed by a trained field crews, with well-maintained equipment, electrofishing
can be a very safe means to collect fish for biological study. Nonetheless, attention to
safety must be paramount for all crew members in order to conduct a successful
electrofishing survey. The amount of current in the water may be in excess of 250 volts.
The amount of amperage generated during typical shocking operations averages 8 amps.
This is enough to kill you if you come in direct skin contact with an electrical source
such as a cathode, anode, or improperly grounded boat or generator. This hazard is
compounded by the fact that the boat and other equipment may be wet.
3.2 Hazard Awareness
Various physical hazards will potentially be present during electrofishing activities.
These physical hazards may include, but may not be limited to:
• Working over, near, or in the water
• Slip, trip, and fall
• Weather
• Material handling, moving, lifting
• Fire/explosion
• Exposure (e.g., cold stress, heat stress, sun burn)
• Noise
• Electrical
• Biological (e.g., fish spine puncture wounds,poisonous insects and plants)
3.3 Safety Rules
Always follow the manufacturer's instructions when installing or operating electrical
equipment. It is each crew leader's responsibility to familiarize crew members with the
equipment and how to operate it. Furthermore, it is the responsibility of each crew
member to assure that others are following proper procedures. If you are asked to do
something that you feel is improper or unsafe, you have the authority to refuse. Don't
depend on someone else to look out for you. Look out for yourself.
Despite all of this, as mentioned above, electroshocking surveys can be conducted in a
safe manner. All that is required is proper attention to detail and the use of the safety
equipment provided to you.
The following are the primary common sense rules that must be followed by all crew
members at all times:
1. Prior to initiating a survey, the crew leader will conduct a safety briefing to
instruct support personnel on basic operation, safety, and hazard awareness. Prior
6

to electrofishing at a given site, the crew will survey the study zone for potential
hazards.
2. Wear rubber gloves when operating/touching electroshocking equipment.
3. Rubber boots will be worn when boat electrofishing and non-breathable, chest
waders will be worn by all crew members for wadeable electrofishing
4. When conducting wadeable electrofishing, all equipment in the water(e.g,nets,
live cars, live wells, buckets)must be non-conductive, insulated, and/or isolated.
5. Due to the conductive nature and added weight, steel-toed boots and/or weight
belts must never be worn while electrofishing.
6. Lug-soled boots are appropriate when wading in soft and or fine substrates (e.g.,
silt,much, gravel, cobble). However, large and firm substrates (e.g.,bedrock,
boulder, large cobble) may be especially slippery and may require felt-soled
wading boots or corkers to safely wade.
7. Never touch a loose wire or make an adjustment while unit is in operation. Rubber
gloves must be worn, safety switches must be released, and the control box turned
off before making any output adjustments. For all other system adjustments,
beyond source, output, and other fine tuning at the control box, the power source
and system must be shut-down, completely.
8. Always use safety switches. Never disable a safety switch or use equipment with
an inoperable safety switch.
9. Never over-extend yourself when netting fish.
10. When wading,walk deliberately and carefully with a shuffling, wide stance to
avoid unseen trip hazards.
11. Communicate hazards to boat operator or fellow wading crew members. Each
crew member has limits to their view. Don't assume everyone sees what you see.
If noise level restricts normal conversation, establish hand signals.
12. Never place your bare hand in the water.
13. Keep the boat deck as dry and clear of obstacles as possible.
14. Look up from the water from time to time to assure that overhanging branches or
other items don't pose a risk.
15. If necessary,particularly for boat or pram operated equipment,wear hearing
protection.
16. Maintain the equipment through routine maintenance checks. If repairs are
needed, get them fixed immediately. Don't wait for the next person to do it.
17. For boat electrofishing, a Personal Floatation Device (PFD)must be worn by all
crew members at all times when dockside or aboard the vessel. PFDs are not
recommended for wadeable electrofishing in water primarily less than waist deep
as they restrict movement and, in certain conditions, may contribute to heat stress.
In doing so, PFDs with wadeable electrofishing actually present a greater hazard
than wading without a PFD. Waters greater than waist deep should be boat
electrofished.
18. Cold weather, dress warmly in layers of reasonably tight-fitting materials.
Additional protections may include glove liners,hats,hand and foot warmers. For
warm weather, light colored and light weight fabrics should be worn. Hydrate
constantly and use sunscreen to protect from sun burn.

SUBJECT: Broad River Fish Tissue Collection and Analysis for NPDES Permit No.
NC0089109
EA Project No. 16244.01
As directed by TRC Environmental Corporation(TRC), EA Engineering, Science, and
Technology, Inc., PBC (EA) collected fish tissue samples upstream and downstream of the
American Zinc Products (AZP)permitted process wastewater discharge point to fulfill their
National Pollutant Discharge Elimination System(NPDES) Permit Condition Item A. (4.): Fish
Tissue Monitoring. Fish tissue samples were analyzed for arsenic (As), cadmium(Cd), and zinc
(Zn).
1. OVERVIEW
AZP, located in Rutherford County,North Carolina,was required to develop a sampling plan to
maintain compliance with the requirements in the facility's NPDES permit. The plan was
submitted to the North Carolina Division of Water Resources (NCDWR) Water Quality
Permitting Section and Water Sciences Section for review and comment. Comments were
addressed in December 2019, and a final version of the sampling plan was submitted in April
20201. The primary component of the sampling plan required an evaluation of target metal
concentrations present within fish tissue.
The project site was located near the AZP metal processing facility in Mooresboro,North
Carolina, and consisted of two sampling locations (one upstream of AZP and one downstream),
approximately four river miles apart(Figures 1 and 2). The upstream location("US"; Figure 1)
served as the reference location for the downstream location("DS"; Figure 2). The surrounding
area consists of stream, forest, industrial, agricultural, and commercial property. Instream cover

within the project area was a combination of logs/woody debris,rocky shoals, overhanging
vegetation, and undercut banks. The three target species were Largemouth Bass (Micropterus
salmoides),Redbreast Sunfish(Lepomis auritus), and Notchlip Redhorse (Moxostoma
collapsum). They each represent different trophic levels—top predator, mid-trophic insectivore,
and mid-trophic omnivore,respectively(Table 1). The minimum target number of fish was six
individuals of each species, and the maximum was ten(10) individuals of each species. If target
species were not encountered in appropriate numbers, secondary target species were substituted,
which included Bluegill, Brassy Jumprock,Flat Bullhead, Smallmouth Bass, White Sucker,
catfish, carp, or other species. Edible-sized individuals, based on the North Carolina Inland
Fishing, Hunting& Trapping Regulations Digest 2021-20222, or the 2019 NCDWR fish tissue
monitoring data3, were targeted to best reflect possible metals contaminants in fish collected by
recreational anglers.

2. FIELD METHODOLOGY
2.1 Field Planning
Planning meetings prior to the field sampling effort were held between EA, TRC, and AZP on a
regular basis between February and May 2022. EA, TRC, and AZP conducted a site visit on
a North Carolina Wildlife Resources Commission(NCWRC).2021.North Carolina Inland Fishing,Hunting&
Trapping Regulations Digest 2021-2022.J.F.Griffin Publishing,LLC.

22 March 2022 to determine access routes and in-river sampling conditions of the upstream and
downstream locations. A detailed and comprehensive Standard Operating Procedures (SOP)
manual was prepared by EA4 and reviewed by TRC and AZP prior to sampling. In addition,
daily meetings were held during the May 2022 fish tissue sampling effort.
EA obtained a Scientific Fish Collection License from the North Carolina Wildlife Resources
Commission (NCWRC) that specified the designated species,numbers of specimens, collection
methods, and sampling locations. The Scientific Fish Tissue Collection License was included in
the SOP prepared by EA4.
2.2 Field Sampling
Field sampling was performed from 16 to 21 May to target amenable river flows and water
levels. Boat electrofishing was the primary collection method used and consisted of a Smith Root
Type VI DC-pulsed electrofisher powered by a 5,000 watt generator,both of which were staged
in a 16-ft jon boat with a 20-horsepower outboard engine. Electrofisher output settings were: 120
pulses per second,pulse width of 4 to 6 milliseconds, and 1,008 volts that collectively produced
4 to 5 amps. Gill nets were used overnight from 16 to 18 May in an attempt to enhance collection
and were retrieved after each overnight set. Gill nets were also used during the day from 16 to 18
May as block nets that were retrieved after completed electrofishing passes. Gill net use was
discontinued after 18 May due to lack of fish collected and excessive debris build-up that
impeded the nets' ability to capture fish.
2.3 Fish Processing
Fish meeting target species requirements were measured,weighed, and examined for any
external physical anomalies (e.g., lacerations, lesions) that could potentially bias the tissue
results. Fish data were recorded on the field datasheets specified in AZR(2020). Fish used for
analysis were placed in Ziploc®bags and frozen in an onsite chest freezer staged in a secure
location at AZP.
Field measuring boards and pan scales used for processing fish were wrapped in clean plastic
wrap, which was changed between each fish species to prevent cross-contamination and possible
bias of results.
2.4 Sample Shipping
Whole fish were double-bagged, labeled with all pertinent information(EA 2022),packed with
wet ice, and shipped in eight insulated and water-tight coolers from AZP to Pace Analytical
Services,LLC (Pace) in Green Bay, Wisconsin, on 23 May. Samples were received in good
condition by Pace on 24 May. Coolers were lined with trash bags to contain ice melt and
cushioned with absorbent pads and bubble wrap as needed. Packed coolers were sealed with

packaging tape to ensure proper closure of cooler lid and cooler plug (if present). A completed
chain-of-custody detailing the specimens contained in each cooler was placed in a Ziploc®bag
and taped to the lid of the cooler. The chain-of-custody provided the unique sample number,
date, and time of collection, and the name and signature of the field collector. The chain-of-
custodies for each sample cooler are provided in Appendix A.
2.5 Laboratory Analysis
Fish tissue samples were analyzed by Pace for total arsenic, cadmium, and zinc. Two fish tissue
samples were duplicated for laboratory analysis at each location, for a maximum of 64 samples
analyzed by the laboratory. The laboratory was responsible for processing fish fillets, including
filleting and scaling fish. All bass, suckers, and sunfish species were processed as skin-on fillets.
The right fillet was sufficient for the tissue quantity required for analysis (2 grams) and was
analyzed for all samples; the left fillet was held on reserve as needed. Analytical results and
reports from Pace are presented in Appendix B.
2.6 Quality Assurance/Quality Control Procedures
In accordance with EA's Corporate Quality Management, a project-specific SOP was developed
to integrate the methodologies and guidance with detailed specifications (EA 2022). It ensured
that the AZP NPDES Permit objectives were met and that the integrity of EA was maintained. It
allowed involved staff members to understand his or her duties and responsibilities.
Field staff participating in the Broad River field work reviewed the SOP prior to start of work.
Both staff members were highly experienced EA field biologists that were well-versed in all fish
sampling operations used and fish species identified at the Broad River site. Field equipment
used for measuring fish were appropriately calibrated prior to use based on the SOP guidance.
GPS coordinates were recorded for upstream and downstream ends of the sampling areas utilized
for both locations.
Field datasheets were hand-written by onsite staff and scanned and checked by an offsite EA
biologist for verification, clarity, and completion(Appendix C). Adjustments were made as
needed t o the datasheets to res
olve any discrepancies or missed information. The field data were
transcribed into Excel format so as to develop summary tables. An experienced EA fish biologist
compared all hand-entered field data against the hard copy field and laboratory datasheets.
2.7 Laboratory Data Evaluation
EA reviewed and performed quality control checks on the analytical data deliverables provided
by Pace. After the data deliverables were received, EA performed a data assessment screening on
the laboratory's analytical data packages and electronic data deliverables. Data were reviewed
for completeness by comparing the sample summary and analytical results to the sample
identification and requested analysis included on the chain-of custody. Review of data usability
was accomplished by comparing the contents of the analytical data packages and quality

3. FIELD NOTES AND OBSERVATIONS
Field sampling information for the Broad River fish tissue collection effort performed to meet
the NPDES permit requirements for AZP is summarized below.
3.1 Upstream Sampling Location (16—19 May)
activities at the upstream sampling This section describes the daily p p $location that occurred during
with GPS waypoints ispresented in Figure 1.
16-19 May. A map of the upstream sampling area yp �'
The GPS waypoints with descriptions are presented in Table 2. Details on fish species collected
at the upstream location are shown in Table 3. A photo log depicting sampling activities is
presented in Appendix D. Access to the upstream sampling location each day was provided by
Jones Farm(US-Launch; Appendix D, Photo 1).
16 May
Enroute to the upstream end(US-EFST—Appendix D, Photo 2),two gill nets were deployed to
function as block nets for electrofishing(US-GN1 —Appendix D,Photos 3 and 4; and US-GN2—
Appendix D, Photos 5 and 6). Two electrofishing passes were made in a downstream direction,
the first began at the Jack McKinney Road Bridge (US-EFST) and ended at gill net US-GN1,
and the second pass started at US-GN1 and ended at US-GN2. After each electrofishing pass, the
gill nets were checked for fish and processed, cleaned of debris, and then redeployed for an
overnight set. Electrofishing efforts yielded seven Redbreast Sunfish (Appendix D,Photo 7) and
10 Notchlip Redhorse (Appendix D,Photo 8) for analysis (Table 3). Fish retained were
associated with some form of instream habitat feature such as logs/woody debris, rocky shoal
areas, overhanging vegetation, and undercut banks. Redbreast Sunfish utilized shoreline areas
with low current velocity and some or no logs/woody debris,whereas the Notchlip Redhorse
were concentrated in higher velocity areas with logs/woody debris or rocky substrates.No
Largemouth Bass were encountered during the electrofishing passes on this day. One particular
woody debris pile was very productive for Notchlip Redhorse and Brassy Jumprock(NLR&BSJ-
SPOT—Appendix D, Photo 9). Brassy Jumprock was not utilized for analysis as it was a
secondary target species. Few fish were seen or collected mid-channel in the open stretches of
the river. Rain showers and thunderstorms occurred throughout the afternoon, causing a brief
stoppage of work. Overall, river conditions were favorable for sampling with amenable river
flows and water clarity.
17 May
The two gill nets (US-GN1 and US-GN2) set the previous day were checked for fish and then
pulled due to heavy debris load (Appendix D,Photo 10). Two clean nets were then deployed at
new locations (US-GN3 —Appendix D, Photos 11 and 12; and US-GN4—Appendix D,Photos
13 and 14). Similar to the previous day, gill nets were used as block nets for electrofishing. The

crew then continued motoring to the upstream end(US-EFST) and began electrofishing in a
downstream direction into the two deployed gill nets. Three electrofishing passes were made:
1)began at US-EFST and ended at US-DN4, 2) started at US-GN4 and ended at US-GN3, and
3)was initiated just downstream of US-GN2 and ended at downstream end of the location
(US-EFEND—Appendix D, Photo 15). The gill nets were checked for fish, cleared of debris, and
redeployed for another overnight set. As observed during the previous day, fish retained came
from instream cover(woody debris, rocks, overhanging vegetation, and undercut banks). Fish
collected for analysis consisted of three Redbreast Sunfish(Table 3). River conditions were
favorable with lower water clarity later in the afternoon, and water levels that dropped
approximately one foot from the previous day.
18 May
The two gill nets (US-GN3 and US-GN4) that soaked overnight were checked for fish and then
removed due to the heavy debris load, similar to that observed the previous day. Gill nets were
not redeployed due to heavy debris loading and lack of target fish captured. The gill nets yielded
11 Snail Bullhead, most of which were below the target length(Table 1). Three electrofishing
passes were made in a downstream direction: the first started at the upstream end(US-EFST) and
ended at the Harris Plant access point(US-EFENDHARRIS—Appendix D, Photo 16); the
second began just downstream of the Harris Plant launch access point and ended just
downstream of US-GN2; and the third pass started at US-EFST and ended at the downstream
end of the sampling location (US-EFEND). Given the previous days success, electrofishing
efforts targeted Largemouth Bass because the target numbers for both Notchlip Redhorse and
Redbreast Sunfish were attained. Electrofishing catches yielded five Largemouth Bass that were
kept for analysis (Appendix D, Photo 17; Table 3). Habitat that yielded the best catches for
Largemouth Bass was a combination of slower water with brush,woody debris, and/or undercut
banks. River conditions remained favorable for sampling with water levels and current velocities
similar to 16 May, but water clarity was lower than observed on 17 May.
19 May
Two electrofishing passes were made: 1) began at the upstream end (US-EFST) and ended at
waypoint US-EFEND519 (Appendix D,Photo 18), and 2) started at that waypoint and ended
approximately 115 meters (m) downstream of waypoint US-GN2. Similar to 18 May,
electrofishing efforts concentrated on the collection of Largemouth Bass as it was the only
remaining target species. Five Largemouth Bass were retained for analysis (Table 3),which
fulfilled the target species requirements for the upstream location. River conditions continued to
remain favorable for sampling with water levels dropping approximately 1 to 2 feet compared to
18 May, and higher water clarity than observed on 16 May.
3.2 Downstream Sampling Location (20—21 May)
This section describes the daily activities at the downstream sampling location that occurred
during 20-21 May. A map of this sampling location with GPS waypoints is presented in Figure 2.
The GPS waypoints with descriptions are presented in Table 2. Details on fish species collected

at the downstream location are shown in Table 3. A photo log depicting sampling activities is
presented in Appendix D. Access to the downstream sampling location each day was provided
by Amer-icon Sand Dredge.
20 May
Three electrofishing passes were made in a downstream direction. The first pass started at DS-
EFST (Appendix D,Photo 19) and ended at DS-EFEND1 (Appendix D,Photos 20 and 21). The
second pass started at DS-EFEND1 and continued to the downstream end of the location(DS-
EFEND—Appendix D, Photo 22). The third pass began approximately 200 m downstream of
DS-EFST and ended at DS-EFEND2. Catches on this day surpassed all others over the duration
of the sampling event, with 10 Notchlip Redhorse (Appendix D, Photo 23), 10 Redbreast Sunfish
(Appendix D, Photo 24), and six Largemouth Bass (Appendix D,Photo 25) collected for analysis
(Table 3). Similar to the upstream location, fish retained were associated with some form of
instream habitat(woody debris,rocky shoal areas, overhanging vegetation, and undercut banks).
Largemouth Bass generally preferred areas with lower velocity combined with logs/woody
debris (Appendix D, Photo 26). Redbreast Sunfish were collected from lower velocity shoreline
areas associated with some cover.No gill nets were used in this location due to the debris
loading and lack of production of target species experienced at the upstream location. River
conditions were favorable with water clarity comparable to the upstream location. The
downstream location was generally wider than the upstream location and contained less
logs/woody debris but larger rocky shoal areas. Despite the lower amounts of logs/woody debris,
fish concentrations were higher within the logs/woody debris present.
21 May
Due to the riffle/run just downstream of the Hwy 221 Bridge being too shallow to navigate, the
first electrofishing pass started just downstream it at waypoint DS-EFST521 (Appendix D, Photo
27) and ended at waypoint DS-EFEND521 (Appendix D, Photo 28). The second pass started at
DS-EFEND521 and ended at the downstream end of this sampling location (DS-EFEND). The
third electrofishing pass went from waypoint DS-EFST to the Amer-icon Sand Dredge launch
(DS-Launch). Electrofishing efforts focused on Largemouth Bass due to the required specimens
for the other two trophic levels being collected the previous day. The remaining four Largemouth
Bass were collected, which completed collections for the downstream location(Table 3).
Largemouth Bass were collected from slower moving water with logs/woody debris. Overall,
river conditions were generally favorable and similar to the previous day in terms of water clarity
and river stage.
