1.0 INTRODUCTION
Terracon Consultants, Inc. (Terracon), on behalf of GoTriangle, prepared this Brownfields
Assessment Report to summarize the results of environmental investigations for the proposed
RUS Bus Station redevelopment located at 200 S. West Street in Raleigh, Wake County, North
Carolina (the "site"). The site is managed under the North Carolina Department of Environmental
Quality (NCDEQ), Division of Waste Management (DWM) Brownfields Program (Project ID:
23010-19-092). This report was developed in accordance with Terracon's Brownfields Data Gap
Assessment Work Plan, dated June 20, 2020 (Terracon, 2020). The Work Plan was approved by
NCDEQ Brownfields Program via email on June 27, 2020.
1.1 Site Location
The site consists of three parcels (Wake County PIN numbers 1703488450, 1703488314,
1703488250) totaling 1.76-acres. As of February 2021, the site has been vacated for proposed
redevelopment, and previously was occupied with:
A restaurant (Five Star) at 511 W. Hargett Street, and
Offices (RCI Builders) at 200 S. West Street.
The coordinates at the approximate center of the property are 5°46'40.8"N, 78°38'47.6"W.
Exhibit 1 presents the site location on a topographic map. The site elevation varies between
approximately 312 to 317 feet above mean sea level, with the lowest topography generally along
the southern site boundary and highest along the northern site boundary. The site is proposed for
redevelopment into the Raleigh Union Station Bus (RUS Bus) Station with a mixed use residential
and commercial building above the station. Proposed residential portions of the build would be
constructed above a parking deck. A layout of the current site features is depicted on Exhibit 2.
Hoffman & Associates will be co -developing the site with GoTriangle. In this role, Hoffman &
Associates will direct construction management and assist with preparation of the Environmental
Management Plan prior to redevelopment of the site.
1.2 Site Description and History
The site is located along the western margin of Raleigh's central business district referred to as the
Warehouse District. Based on information obtained from historical site investigations and the Wake
County GIS website, the site is comprised of three parcels totaling approximately 1.76-acres. The
parcels are improved with multiple structures that occupy the majority of the land on the site. The site
is currently vacant. Since the late 1890s, the area has been used for railroad, warehouse storage,
and various other industrial or commercial operations.
1.3 Historical On -Site Operations
The structure located at 200 S. West Street, is a two-story commercial/retail building with a
basement. The current structure was constructed in 1920 and remodeled in 1975 and 2013. Prior
to 1920, occupants of the site included Raleigh Ice & Refrigeration Company (1896 to 1903) and
the Johnson & Johnson Ice Factory (1909 to 1914). The Imperial Casket Co occupied the structure

Irerracon
from at least 1920 to 1981 with additional occupants of the building including: US Supply Co (1986
to 1991), Philip Crawford & Associated Design (1997 to 2002), and Five Star Restaurant (2003 to
2020).
The structures located at 206 and 210 S. West Street are interconnected two-story warehouse
structures with basements in portions of the building. The current structures were constructed in
1922 (206 S. West Street) and 1910 (210 S. West Street). Prior occupants of the site include:
Hacks Ellington & Co Sash -Door -Blind Co (1896), Midgley Spoke Factory (1903), National Biscuit
Company (1909 to 1914) and Monument Works (1914). Dillon Supply Co occupied the structures
and converted them into their current formation by at least 1936. By the early 1990s, Dillon Supply
sold fork lift truck parts within the on -site warehouse area. The majority of the on -site structures
have remained vacant since 2004. The adjacent rail spur to the west of the property has been
present since at least 1896.
1.4 Historical Site Investigations
This section provides a chronological description of historical environmental investigations
conducted at the site. Approximate sample locations from previous investigations, if known, are
depicted on Exhibit 3. Analytical data from prior reports are summarized in Table 1 and Table 2.
1.4.1 Phase I Environmental Site Assessment — 2003
The 2003 ESA completed by URS indicated that potential groundwater contamination may have
been present at the site due to one or more unknown sources up -gradient from the site. The
unknown source(s) could include prior petroleum releases with detections above groundwater
standards, prior automotive repair operations, and/or prior dry-cleaning operations.
The presence of active and historical rail sidings adjacent to the parcel raises the possibility of
residual contamination. Common rail line contamination can include oil and grease from engines,
diesel and coal residues from spills, polychlorinated biphenyls (PCBs) from railroad transformers,
creosote from rail timber preservatives, and/or a variety of chemicals carried as freight that may
have spilled or leaked during transit or during loading/unloading. The former structure contained a
loading dock facing the active rail line (URS, 2003).
1.4.2 Limited Site Investigation — 2004
A Phase II Environmental Site Assessment (URS, 2004) included collection of one groundwater
sample (MW-C-03) from the northern portion of the site, which contained benzene, 1,2-
dichloroethane (DCA), tetrachloroethene (PCE), and trichloroethene (TCE) detections above their
respective Title 15A North Carolina Administrative Code 2L Groundwater Quality Standards (2L
Standard). One soil sample was collected from the boring in the same location as the groundwater
sample (MW-C-03), which did not contain detections of constituents of concern above the Soil
Remediation Goals. Also, staining and/or odors were not observed during the sample collection
activities.
Soil samples were collected from two borings in the western portion of the site. Arsenic was
detected in soil sample SB-C-05 (10 feet below land surface [bls]) above the industrial/commercial

Preliminary Soil Remediation Goal (PSRG) and in soil sample SB-C-04 (9 feet bls) above the
residential PSRG.
1.5 Regulatory Status
The site has the following regulatory listings:
Inactive Hazardous Sites Branch (IHSB) Site ID: NONCD0001124; Name: Raleigh
TTA-Wilson Parcel
IHSB Site ID: NONCD0001126; Name: Raleigh TTA-Parcel B
The site was granted eligibility into the NCDEQ Brownfields Program on March 28, 2019 (Site ID
No. 23010-19-092).
1.6 Summary and Data Gap Evaluation
The existing data set provides the preliminary basis for our understanding of contaminant
distribution and concentrations at the site. Data was compared to the most recent 2L Standards
(April 2013) and Vapor Intrusion Screening Levels (January 2021). Data is summarized in
Table 1 and Table 2.
Based upon our evaluation of the previous site assessment activities, Terracon has developed the
following summary of existing data, organized by area of concern (AOC) (Exhibit 3):
Adjacent Rail Spur (AOC-1): A rail spur has been present along the western
portion of the site since at least 1896. Common rail line contamination can include
oil and grease from engines, diesel and coal residues from spills, PCBs from
railroad transformers, creosote from rail timber preservatives, and/or a variety of
chemicals carried as freight that may have spilled or leaked during transit or
loading/unloading. There is the potential for impacts in this vicinity.
Off -site and Up -gradient Groundwater Impacts (AOC-2): Multiple former dry
cleaning and gasoline station operations were located to the north and northwest
of the site. Available analytical data indicates groundwater contamination from
these off -site operations extend onto the site.
Based on the previous site assessment activities, as summarized above, Terracon has identified
the following data gaps:
AOC-1: Potential impacts have not been evaluated for the adjacent rail spur.
Potential soil contamination for the proposed redevelopment has not been
evaluated.
AOC-2: Potential groundwater and soil vapor intrusion pathways for the proposed
redevelopment on -site have not been sufficiently evaluated.
Terracon proposed to collect shallow soil samples across the site to evaluate non-residential
worker and construction worker exposure pathways. Additionally, Terracon proposed to collect

Irerracon
deep soil gas and/or sub -slab soil vapor samples to evaluate the potential for vapor intrusion. At
the time of the Work Plan, Terracon had not reviewed a final redevelopment plan or a final cut/fill
plan for the site. Terracon will address potential import/export soil samples in the Environmental
Management Plan (EMP) being developed for the site.
Terracon understands that the Prospective Developer (GoTriangle) intends to restrict groundwater
usage. As part of the Brownfields Agreement, this will be recorded as a land use restriction and is
not considered a complete exposure pathway. Although detailed construction plans have not yet
been developed, it is possible that dewatering may be needed during construction activities. Due
to the potential for construction worker exposure to groundwater and to identify appropriate
handling and disposal options, Terracon proposed the collection of groundwater samples.
Surface water and sediment are not located on the site; and therefore, do not need further
investigation. It is Terracon's understanding that groundwater will be restricted for the site;
therefore, Terracon considers the Groundwater Combined Pathway incomplete and will not be
evaluating groundwater use in the NCDEQ risk calculator.
2.0 PROJECT DESCRIPTION
Terracon conducted the Brownfields assessment activities in general accordance with the Work
Plan (Terracon, 2020), and deviations stated below in Section 2.2. The Brownfields assessment

3.0 INVESTIGATION ACTIVITIES
Field investigation activities were conducted in January and February 2021 in accordance with
Terracon's data gap assessment work plan (Terracon, 2020). The revised sampling and analysis
plan from the Work Plan is included as Table 3.
3.1 Utility Clearance and Geophysical Survey
Approximately 4 business days prior to site mobilization, Terracon submitted a locate request to
the public utility locator (NC 811) to arrange for location of underground public utilities from the
street up to the utility meter. Terracon also provided utility locating services to attempt to locate
and mark utilities near the proposed sample locations.
3.2 Soil Sampling
On January 26 and January 27, 2021, Terracon advanced four soil borings (SB-01 through
S13-04) and collected samples at depth intervals 0-3 feet bls and 3-8 feet bls. The soil borings were
advanced to assess potential shallow soil impacts that may be encountered during redevelopment.
The borings were advanced with direct push technology (DPT) drilling or hand auguring
techniques. Soil samples were collected continuously, logged for lithology, and screened in the
field with a photoionization detector (PID). The locations of the soil borings are shown on
Exhibit 4. Soil Iithologic logs are included in Appendix A.
Nine soil samples were submitted for laboratory analyses for one or more of the following:
■ Volatile organic compounds (VOCs) via U.S. Environmental Protection Agency
(EPA) Method 8260;
■ Semi -volatile organic compounds (SVOCs) via EPA Method 8270;
■ Eight Resource Conservation and Recovery Act (RCRA) Metals via EPA Method
6010/7471;
■ Hexavalent chromium via EPA Method 7199; and
■ Polychlorinated biphenyl (PCBs) via EPA Method 8082A.
Grab samples for VOC analysis were collected from the depth considered to have a high potential
for contamination, as determined by field observations and screening with the PID. Samples for
SVOC and RCRA metals analyses were composited from each interval. Upon collection, soil
samples were packed in an ice filled cooler and shipped under chain -of -custody protocols to Pace
Analytical, a North Carolina certified laboratory in Mount Juliet, Tennessee for analysis.
Table 3 provides a summary of the laboratory analyses for which each soil sample was submitted.
Non -dedicated sampling equipment and field instruments were decontaminated after each sample
was collected using a non -phosphate soap wash, followed by a potable water rinse. Soil cuttings
were containerized and boring locations were patched with materials similar to the existing
material, to the extent practical.

May 4, 2021 Terracon Project No. 70187342
3.3 Groundwater Sampling
Two of the soil borings were advanced to groundwater and converted into temporary groundwater
monitoring wells (TW-02 and TW-03). The wells were constructed as follows:
10 feet of 1-inch diameter, 0.010-inch slotted polyvinyl chloride (PVC) screen with
a threaded cap;
1-inch diameter, threaded, flush -joint PVC riser pipe to surface;
Pre -sieved 20/40 grade silica sand to approximately 1 to 2 feet above the well
screen; and
Hydrated bentonite chips (approximately 1 to 2 feet) on top of the sand pack.
An existing monitoring well (MW-1) was sampled in addition to the temporary monitoring wells.
The wells were purged using a peristaltic pump with pH and turbidity measured during purging.
One groundwater sample was collected from each monitoring well using low -flow sampling
techniques, including new, disposable tubing. Terracon collected field parameters (i.e.,
temperature, dissolved oxygen, conductivity, specific conductance, and pH) while sampling the
groundwater to help ensure the collection of representative groundwater samples. The samples
were submitted for the following laboratory analyses:
■ VOCs via EPA Method 8260;
■ SVOCs via EPA Method 8270;
■ Eight RCRA Metals, iron, and manganese via EPA Method 6010/7471;
■ Hexavalent chromium via EPA Method 7199;
■ PCBs via EPA Method 8082A; and
■ 1,4-Dioxane via EPA Method 8260SIM.
Groundwater sampling field forms are included in Appendix B. Upon completion of groundwater
sampling activities, a North Carolina licensed driller abandoned the temporary monitoring wells.
Based on observations of field parameters, low dissolved oxygen levels were detected in the
groundwater. This is an indication of strong reducing conditions in groundwater, that caused
naturally -occurring metals in the aquifer matrix to reduce to more soluble species (Table 5).
3.4 Soil Vapor Investigation
Three deep soil vapor points (SG-01 through SG-03) and two sub -slab soil vapor points (SV-01
and SV-03) were installed as part of this investigation. All of the soil vapor points were installed
to collect soil vapor from beneath the building sub -slab. The soil vapor points were
constructed in general accordance with the practices outlined in the NCDEQ Division of Waste
Management Vapor Intrusion Guidance (March 2018) and the Interstate Technology Regulatory
Council Vapor Intrusion Pathway: A Practical Guideline (January 2007).
The deep soil vapor monitoring points were installed within boreholes advanced with DPT drilling
techniques to a depth of approximately 10 feet bls. The points were constructed with a stainless -

steel screen with a barbed fitting at the top to connect to small bore (0.25 inches O.D.) Teflon° -
lined sample tubing. A sand filter pack was placed within the annulus to a height of approximately
6 inches to 1 foot above the top of the screen point. An approximate 1-foot thick layer of dry,
granular (No. 20) bentonite was placed in the borehole annulus above the sand pack followed by
a layer of bentonite hydrated with distilled water to the land surface. The monitoring points were
capped, and each point was allowed to equilibrate for at least 2 hours before sampling.
The two sub -slab monitoring points consisted of an assembled Vapor Pin TM installed within a 5/8-
inch diameter hole. The hole was lined with a pre-cut silicone sleeve that the Vapor Pin TM was
hammered in to create a competent seal with the concrete floor slab. Terracon used 0.25-inch
outside diameter Teflon° lined tubing to connect the Vapor PinTm assembly to the laboratory
supplied Summa° canisters.
A shut-in (dead -head) test was conducted before sampling to check for leaks in the above -ground
purge/sampling manifold. The flow controller influent was capped, and a hand pump was used to
induce a negative pressure reading on the manifold pressure gauge. If there was an observable
loss of vacuum, the fittings were adjusted until the vacuum in the sample train did not noticeably
dissipate. Loss of vacuum was not observed in the canisters during the shut-in test.
A 0.25-inch outside diameter Teflon° lined tube and Swagelok° fittings were used to connect the
monitoring point assembly to a laboratory -supplied, batch -certified 1.0-liter Summa° canister. A
helium tracer test was conducted prior to collecting the sample. The tracer test serves as a quality
assurance/quality control (QA/QC) method to verify the integrity of the soil vapor point seal in addition
to the connection of the sampling manifold and the soil vapor point. A field instrument capable of
measuring helium concentrations down to 25 parts per million was used to verify the presence and
concentration of helium in the sample points and/or within the sampling manifolds.
The protocol for using a tracer gas was to enclose the sampling point and the sampling manifold with
a shroud. The helium tracer gas was released into the shroud until the atmosphere inside the shroud
is approximately 10 to 20 percent helium. Approximately three purge volumes (one purge volume
being equal to the volume within the borehole through the slab and the sample tubing) were evacuated
through Teflon° -lined tubing that passes through the shroud using a hand pump. Purge samples were
screened for helium to assess for leaks in the well seal and/or sampling manifold after removal of
each well volume. The annulus was considered to be sufficiently sealed when helium concentrations
detected within the sampling point were less than 10 percent (%) of the helium concentration in the
shroud (NCDEQ DWM, 2018). The shroud was enriched with greater than 10% helium. The
concentration of helium observed within each exterior soil vapor point was less than 1 % of the total
shroud helium in each exterior soil vapor point.
After completion of the helium tracer test, the valve of the purge device was closed, and the sample
canister valve was opened to collect soil vapor for laboratory analysis. The samples were collected
in a laboratory supplied, batch certified 1.0-liter Summa canisters connected to sample tubing
using Swagelok° fittings at the soil vapor point. The canister was filled using a dedicated flow

controller and set to a sample rate of less than or equal to 200 milliliters per minute. An in -line
vacuum gauge was installed to the sample controller to verify initial vacuum levels within the
canister and as an indicator that final equalization was reached. The sample canister valve was
closed when the gauge measured less than 6 inches of mercury (Hg) vacuum and the final vacuum
was not be allowed to reach 0 inches Hg vacuum. At the conclusion of the sampling event, the
final canister vacuum was recorded. The canister was packaged and delivered along with chain -
of -custody documentation to Pace Analytical National for analysis of VOCs via EPA Method
TO-15.
Photographs and field forms are included in Appendix B. The soil gas sampling points were
abandoned on the same day as sample collection. Terracon has included lithologic logs for soil
vapor points SG-01, SG-02, and SG-03 as Appendix A. Based on field observations, remaining
soil vapor points did not require additional screening or logging of soil; and therefore, the borings
were not formally logged.
3.5 Investigative Derived Wastes
Soil cuttings were containerized per NCDEQ regulations. Investigative -derived waste containers
were labeled and left on the site for subsequent disposal. Based on the lack of area to spread the
soil, the drum is pending off -site disposal.
4.0 RESULTS
Terracon presents a summary of results in the following subsections. Copies of laboratory
analytical reports are included in Appendix C.
4.1 Soil Analytical Results
Analytical results were compared to the NCDEQ's IHSB PSRGs for Restricted -Use (Non -
Residential) and Unrestricted -Use (Residential). Analytical results for soil samples are as follows:
VOCs were not detected above Residential and/or Non -Residential PSRGs.
Benzo(a)pyrene was detected in two soil samples above the Residential PSRG.
Remaining SVOCs were not detected above the Residential and/or Industrial
PSRGs.
Arsenic was detected in six soil samples ranging from 0.955J to 2.44 milligrams per
kilogram (mg/kg), which was above the Residential PSRG (0.68 mg/kg) but below
the Non -Residential PSRG (3.0 mg/kg). Known releases of arsenic -containing
compounds have not occurred at the site. Arsenic concentrations in North Carolina
soil range from 1 to 18 mg/kg (Dragun and Chekiri, 2005); and therefore, the arsenic
concentrations in the soil samples are consistent with naturally occurring
background levels.
a Hexavalent chromium was detected at estimated concentrations above its
Residential PSRG in two soil samples (SB-02, 0.522J mg/kg; SB-03, 0.349J

mg/kg), each at depths of 3-8 feet bls. Hexavalent chromium was not detected in
other soil samples above laboratory reporting limits. Trivalent chromium was
derived from the difference of total chromium and hexavalent chromium and was
not detected above applicable standards in the soil samples. Known releases of
chromium -containing compounds have not occurred at the site. The detected
hexavalent chromium concentrations are at very low, "estimated" concentrations,
and consistent with naturally occurring background levels.
The remaining metal compounds were not detected above Residential and/or Non -
Residential PSRGs.
Soil analytical results are summarized on Table 4. A copy of the laboratory report is provided in
Appendix C.
4.2 Groundwater Analytical Results
Analytical results were compared to the 2L Standards and NCDEQ's Residential and
Non -Residential Vapor Intrusion Screening Levels, Groundwater Screening Levels (GW-VISLs).
Results are summarized as follows.
VOC compounds were not detected above laboratory detection limits.
Benzo(a)anthracene, benzo(a)pyrene, dibens(a,h)anthracene, and indeno(1,2,3-
cd)pyrene were detected in well MW-1 above the 2L Standards. Benzo(a)pyrene
was also detected above the 2L Standard in well TW-03. Benzo(a)anthracene does
not exceed the GW-VISLs.
Chromium was detected above the 2L Standard in TW-03 and hexavalent
chromium was detected below the 2L Standard in the same sample.
Iron and manganese were analyzed for future construction permitting purposes with
the City of Raleigh; however, iron was detected above the 2L Standard in samples
TW-02 and TW-03, and manganese was detected above the 2L Standard in each
of the samples. The elevated concentrations of iron and manganese is likely caused
strong reducing conditions in groundwater, causing naturally -occurring metals in
the aquifer matrix to reduce to more soluble species (i.e., Fe+3 to Fe+2 and Mn+4
to Mn+2).
Remaining SVOC and metal compounds were not detected above the 2L Standard.
A summary of the constituents detected in groundwater is included as Table 5. A copy of the
laboratory report is provided in Appendix C.
4.3 Soil Vapor Analytical Results
Analytical results were compared with the NCDEQ DWM Residential and Non -Residential Vapor
Intrusion Soil Gas Screening Levels (VI-SGSLs). Results are as follows.
VOCs were detected in one or more of the soil vapor samples collected;

The identified compounds in SV-01, SV-03, and SG-01 were not detected at
concentrations exceeding their Residential or Non -Residential VI-SGSLs;
1,3-Butadiene was detected in SG-02 and n-Hexane was detected in SG-03 at
concentrations exceeding their Residential VI-SGSLs, but do not exceed their
Non -Residential VI-SGSLs.
Soil vapor analytical results are summarized in Table 6. A copy of the laboratory report is provided
in Appendix C.
4.4 Brownfields Risk Calculator Results
Terracon utilized the NCDEQ Risk Calculator (January 2021) to evaluate the risk for the soil and
soil -gas to indoor air exposure pathway. The soil combined exposure pathway for the Resident,
Non -Residential Worker, and Construction Worker exposure scenarios was evaluated. The
residential soil gas to indoor air pathway and the non-residential worker soil gas to indoor air
pathway were evaluated. In accordance with the Work Plan, the site is an individual exposure unit.
The highest concentration of each detected analyte within the exposure unit was included in the
evaluation.
The cumulative carcinogenic risk and the hazard index calculated based on these exposure units
does not exceed for the NCDEQ's acceptable levels for cumulative cancerous effects (10-1) and
non -cancerous systemic effects (hazard index greater than or equal to one) for direct contact soil
or the resident/non-resident indoor air scenario.
Below are the calculated cumulative carcinogenic risk and non -cancerous systemic effects for
each exposure unit for soil gas to indoor air:
Residential: Cumulative Carcinogenic Risk: 1.9x10-5
Cumulative Non -Carcinogenic Risk: 0.89
Non -Residential: Cumulative Carcinogenic Risk: 1.4x10-6
Cumulative Non -Carcinogenic Risk: 0.071
The NCDEQ Risk Calculator summary is included in Appendix D. A copy of the proposed
redevelopment plan is included as Appendix E.
5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on this investigation, Terracon provides the following conclusions and recommendations:
Terracon evaluated the risk of exposure associated with on -site soils, groundwater
and soil vapor. According to the results of the NCDEQ's risk calculator, the
carcinogenic and non -carcinogenic risk associated with the soil combined exposure

pathway is not exceeded for the Resident, Non -Residential Worker, and
Construction Worker exposure scenarios.
Prior to earth moving activities, Terracon will prepare an EMP for the site and will
address the need for a HASP for construction activities anticipated to disturb
localized areas of potentially impacted soil.
Historical analytical data indicates groundwater is impacted by SVOCs and metals
above the 2L Standards. Terracon understands a groundwater use restriction will
be implemented at the site to address risk associated with impacted groundwater.
Analytical data used for the risk calculator for Soil Gas to Indoor Air Pathways does
not indicate a human -health risk for the Resident and Non -Residential Worker
exposure scenarios for the proposed on -site building with ground -level retail. Based
on the proposed bus station and parking deck, the exposure pathway is incomplete.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
FTChave
been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
FSS
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
ONE LAB. NATIONWIDE.
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
CP
IP
FTC
FSS
(dry)
Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL
Method Detection Limit.
[Cn]
MDL (dry)
Method Detection Limit.
RDL
Reported Detection Limit.
Fr
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
6
QC
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
E
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
F
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier
Description
C3
The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Method sensitivity check is acceptable.
J
The identification of the analyte is acceptable; the reported value is an estimate.
J4
The associated batch QC was outside the established quality control range for accuracy.
J5
The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.
v
The sample concentration is too high to evaluate accurate spike recoveries.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
FTChave
been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
FSS
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
ONE LAB. NATIONWIDE.
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
CP
IP
FTC
FSS
(dry)
Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL
Method Detection Limit.
[Cn]
MDL (dry)
Method Detection Limit.
RDL
Reported Detection Limit.
Fr
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
s
QC
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
E
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
F
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier
Description
C4
The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Data is likely to show a low bias concerning the result.
J
The identification of the analyte is acceptable; the reported value is an estimate.
J3
The associated batch QC was outside the established quality control range for precision.
J4
The associated batch QC was outside the established quality control range for accuracy.
J5
The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.
P
RPD between the primary and confirmatory analysis exceeded 40%.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
FTChave
been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
FSS
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
ONE LAB. NATIONWIDE.
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
CP
IP
FTC
FSS
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
[Cn]
RDL
Reported Detection Limit.
Rec.
Recovery.
FSr
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
6
QC
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
a
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
FSC
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
FTChave
been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
FSS
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
ONE LAB. NATIONWIDE.
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
CP
IP
FTC
FSS
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
[Cn]
RDL
Reported Detection Limit.
Rec.
Recovery.
FSr
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
6
QC
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
a
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
FSC
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier
Description
J
The identification of the analyte is acceptable; the reported value is an estimate.
