Brownfields Assessment Report Irerracon
120 Kindley Street Raleigh, North Carolina
May 18, 2021 Terracon Project No. 70217022
1.0 INTRODUCTION
Terracon Consultants, Inc. (Terracon), on behalf of Capital City Urban Development, LLC (CCUD),
prepared this Brownfields Assessment Report to summarize environmental investigations at the
parcel and adjacent North Carolina Department of Transportation (NCDOT) right-of-way (ROW)
comprising the proposed redevelopment, addressed as 120 Kindley Street in Raleigh, Wake
County, North Carolina (the "site"). This Brownfields Assessment was completed to evaluate
project feasibility and environmental risk -related construction costs and was conducted in
accordance with standard North Carolina Department of Environmental Quality (NCDEQ)
Brownfields Program protocols. The site is currently awaiting formal eligibility into the NCDEQ
Brownfields Program at the issuance of this Brownfields Assessment Report.
1.1 Site Description and History
The site totals approximately 10 acres consisting of a 5.89-acre tax parcel (Wake County Parcel
PIN 1703559479) and 4.105 acres surrounding the main parcel to the south and west which will be
acquired from the NCDOT. The parcel address is 120 Kindley Street in Raleigh, Wake County,
North Carolina. The site contains an approximate 47,195-square foot former office/data center, paved
parking areas, wooded land and NCDOT ROW. In addition, the site contains an 15,000-gallon diesel
underground storage tank (UST), located south of the on -site building, that was used for two
emergency generators and a water supply well, located southeast of the on -site building, that was
used as a secondary water source for the on -site chiller system. At the time of the Brownfields
Assessment, the on -site structure was vacant and boarded shut. Terracon could not safely access
the building interior.
The coordinates at the approximate center of the property are 35046'13.01 "N, 78°38'33.73"W.
Exhibit 1 illustrates the site location on a topographic map. The site elevation varies between
approximately 270 to 310 feet above mean sea level, with the lowest topography generally on
western and southern boundaries of the site along McDowell Street and the McDowell Street exit
ramp from Martin Luther King Jr. Boulevard. The site is proposed for redevelopment into one or
more multi -unit buildings. The ground -floor of the first proposed building (Building 1) will consist
of parking and retail. Upper levels will contain residential units (Exhibits 2 and 3).
Based on a review of historical information, the site, including the NCDOT ROW portion, was
previously developed by numerous residential structures and a church from at least 1909 until the mid
to late 1970s, when the structures were razed. The site remained undeveloped from at least 1981
until 1986, when the site was developed with the currently existing on -site structure. The site was
utilized as a data center for Duke Energy from 1986 until 2014. The NCDOT ROW portion of the site
was developed with the current ROW and McDowell Street exit between 1993 and 1998. The on -site
building has been vacant since approximately 2014.

The surrounding properties were developed for residential use until the 1970s when the structures
were razed. The nearby properties remained cleared until roads and commercial properties were
developed in the 1990s.
1.2 Development Plans
Terracon understands that CCUD plans to initially redevelop the site with one multi -story, mixed -
use (retail/commercial and multi -family residential) building (Building 1) with a footprint of
approximately 61,000 square feet in the southeastern portion of the site. Additional on -site
buildings (Buildings 2 through 5) may be constructed in the future and could include multi -family
residential. Current development plans also include an extension of Kindley Street through the
middle of the site connecting to Martin Luther King Jr. Boulevard and the addition of parking lots
and green spaces throughout the site.
Proposed grading plans indicate an approximate cut volume of 25,000 cubic yards to depths of 20
feet in the footprint of Building 1 and cuts up to 5 feet in areas east and west of Building 1. A
majority of the cut soil (approximately 18,000 cubic yards) will be staged on -site in a stockpile
located northwest of Building 1. Approximately 7,000 cubic yards of cut soil is proposed to be
exported off -site. The proposed grading plans do not indicate that soil will be imported to the site.
Proposed grading contours are depicted in Exhibit 3. Soil boring and soil vapor point locations
and depths for this assessment were determined based on the proposed building locations and
grading plans.
1.3 Historical On -Site Operations
The site was previously developed by numerous residential structures and a church from at least
1909 until the mid to late 1970s, when the structures were razed. The site remained undeveloped
from at least 1981 until 1986, when the site was developed with the currently existing on -site structure.
The site was utilized as a data center for Duke Energy from 1986 until 2014. The NCDOT ROW
portion of the site was developed with the current ROW and McDowell Street exit between 1993 and
1998. The on -site building has been vacant since approximately 2014.
A 15,000-gallon diesel UST was installed on the site in 1986 and previously fueled two former
emergency generators that operated at the site. The UST is located along the southern exterior
wall of the on -site structure (Exhibit 2). The UST is constructed of single -walled fiberglass -
reinforced plastic (FRP) with single -walled FRP product lines, catchment basin spill protection and
overfill alarm. According to a UST 17A form prepared in 2011, an NCDEQ triennial inspection
completed in 2011 identified a possible release at the surface of the UST fill port (Progress, 2011).
Numerous violations were reported in the 2011 inspection and the UST failed inspection; however,
a Leaking Underground Storage Tank (LUST) incident has not been recorded at the site. Mr.
Christopher Gilbert, an environmental remediation contractor with Duke Energy, provided a UST
17A form (UST Suspected Release 24 Hour Notice) and a UST 17B form (UST Suspected Release
7 Day Notice) dated 2011 to Terracon for the on -site UST (Progress, 2011 a and 2011 b).

Irerracon
According to a 2014 triennial UST inspection report, violations were not reported, and the UST
passed inspection (Vital, 2014). According to Mr. Rick Green, representative for Capital City Urban
Development LLC, the current site owner, approximately 12,000-gallons of diesel fuel and water
was removed from the UST in May 2017 by Coastal Carolina Recycling.
A Notice of Violation (NOV) was issued for the site by the NCDEQ — UST Section in April 2019,
due to the NCDEQ inspector not being able to access the site for an inspection (NCDEQ, 2019).
The NOV was resolved by May 2019 and confirmed in email from Ms. Rebecca Lloyd,
Environmental Specialist/Geologist with the UST Section (Lloyd, 2020).
The operational status of the UST system was changed to temporary closure and in compliance
according to a NCDEQ Division of Waste Management (DW M) — UST Section Form UST-8 dated
October 4, 2019 (Exploris, 2019).
A water supply well is located on the southern portion of the site. According to Mr. Green, the well
was reportedly utilized as a secondary water source for the on -site chiller system. The well
construction details are unknown.
1.4 Historical Site Investigations
This section provides a chronological description of historical environmental and geotechnical
investigations conducted at the site.
1.4.1 Site Check Report — 2011
A release occurred while transferring fuel from two 100-gallon day tanks associated with the
temporary generators staged at the site during the installation of the second emergency generator
(Geologic, 2011). The report indicates approximately one gallon of fuel was spilled on the ground,
which was the source of diesel odors observed during the 2011 triennial UST inspection. Between
November and December 2011, approximately 7 cubic yards of contaminated soil and gravel were
removed during mitigation efforts (Geologic, 2011). Information regarding field screening results
and confirmation sampling was not available for review.
Six soil borings were advanced around the perimeter of the UST to a depth below the bottom of
the UST (approximately 13-16 feet below land surface [bls]) and a soil sample was collected from
an interval below the bottom of the UST in each boring. The soil samples were submitted for
laboratory analysis of total petroleum hydrocarbons — diesel range organics (DRO) and gasoline
range organics (GRO). Analytical results reported DRO concentrations between 2.7 and 5.8 parts
per million (ppm), below the NCDEQ action level (10 ppm at that time). GRO concentrations were
not reported above laboratory detection limits. Groundwater was not encountered during the soil
boring installations; therefore, groundwater samples were not collected (Geologic, 2011).

1.4.2 Phase I Environmental Site Assessments — 2015 to 2021
Terracon completed three Phase I Environmental Site Assessments (ESAs) at the site between
2015 and 2021 (Terracon, 2015; Terracon, 2019; and Terracon, 2021 a).
Terracon identified the on -site 15,000-gallon diesel UST as a recognized environmental condition
(REC) for the site in the three ESAs based on the UST suspected release forms dated 2011
provided by Mr. Christopher Gilbert. Additional on -site or off -site RECs were not identified.
1.4.3 Geotechnical Report — 2018
According to a Geotechnical Engineering Report prepared by Stewart Engineering dated
June 11, 2018, a geotechnical exploration project was completed at the site and included thirteen
(13) soil borings completed at depths ranging from 25 to 64 feet bls. The report noted that
groundwater was encountered in several of the soil borings at depth between 43.5 to 50 feet bls
and that noxious odors and/or stained soils were not observed in the cuttings exposed at the site.
Weathered rock was encountered in a majority of the borings at approximately 24 feet bls and
bedrock was encountered between 42 and 62 feet bls.
1.5 Regulatory Status
The site is listed on the UST database under facility ID #00-0-0000006713 for operating a
15,000-gallon diesel UST installed in 1986. The UST is still located on -site, although it was placed
in temporary closure in May 2019.
CCUD submitted a Brownfields Property Application on March 17, 2021. The site is currently
awaiting formal eligibility into the NCDEQ Brownfields Program at the issuance of this Brownfields
Assessment Report.
2.0 PROJECT DESCRIPTION
In anticipation of acceptance into the Brownfields Program, Terracon conducted an assessment
that included:
Preparation of a Health and Safety Plan (HASP) and underground utility clearance via
ground -penetrating radar (GPR) and utility locator;
Advancement and sampling of twenty (20) soil borings; and
Installation and sampling of seven (7) temporary exterior soil vapor monitoring points.
Sample locations are shown on Exhibits 2 and 3 and are summarized as part of the Sample and
Analysis Plan (SAP) (Table 1). Field methods are discussed in Section 3 of this report.

2.1 Objectives
The purpose of the investigation was to evaluate project feasibility and to evaluate potential
environmental risks in on -site soil and soil vapor that may be encountered during site development
and future use. It is Terracon's understanding that groundwater will be restricted for the site, the
on -site well will be abandoned, and it is unlikely to be encountered during redevelopment based
on the depth to water (Stewart, 2018). Therefore, on -site groundwater was not evaluated.
2.2 Investigation Limitations
The on -site building was boarded shut and could not be safely accessed. Thus, Terracon was
unable to conduct sub -slab soil and soil vapor sampling as part of this investigation.
The location of soil vapor point SV-06 was inaccessible by a drill rig. The point was installed via a
handheld Hilti hammer drill utilizing decontaminated 1.25-inch steel rods and a disposable steel
drive point. Soil was not recovered during advancement of the SV-06; therefore, a lithology log
was not completed.
2.3 Standard of Care
Terracon's services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same time.
Terracon makes no warranties, either express or implied, regarding the findings, conclusions, or
recommendations. Please note that Terracon does not warrant the work of laboratories, regulatory
agencies, or other third parties supplying information used in the preparation of the report.
2.4 Additional Scope Limitations
Findings, conclusions, and recommendations resulting from these services are based upon
information derived from the on -site activities and other services performed under this scope of
work; such information is subject to change over time. Certain indicators of the presence of
hazardous substances, petroleum products, or other constituents may have been latent,
inaccessible, unobservable, non -detectable, or not present during these services. We cannot
represent that the site contains no hazardous substances, toxic materials, petroleum products, or
other latent conditions beyond those identified during this investigation. Subsurface conditions
may vary from those encountered at specific borings or wells or during other surveys, tests,
assessments, investigations, or exploratory services.
The data, interpretations, findings, and our recommendations are based solely upon data obtained
at the time and within the scope of these services.

3.0 INVESTIGATION ACTIVITIES
Field investigation activities were conducted in April 2021. An investigation SAP summary is
included as Table 1.
3.1 Utility Clearance and Geophysical Survey
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 completed a private
utility locate utilizing ground -penetrating radar and a utility locator in an attempt to locate and mark
utilities near the proposed sample locations.
3.2 Soil Sampling
On April 13 and 14, 2021, twenty (20) soil borings (SB-01 through SB-20) were advanced and
sampled at one or more depth intervals. Soil borings were advanced to assess potential
environmental impacts associated with the former site operations to shallow soil that may be
encountered during redevelopment. SB-01 through SB-17 were completed in the proposed
building locations and cut areas. SB-18 through SB-20 were completed adjacent to the 15,000-
gallon diesel UST. The borings were advanced with direct push technology (DPT) or via hand
auger. 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 2.
Soil Iithology logs are included in Appendix A. Photographs of typical soil borings are included in
Appendix B.
Twenty-eight (28) soil samples were submitted for laboratory analysis of the following:
Volatile organic compounds (VOCs) via EPA Method 8260;
Semi -volatile organic compounds (SVOCs) via EPA Method 8270;

Resource Conservation and Recovery Act (RCRA) 8 Metals via EPA Method 6010/7471;
and
Hexavalent chromium via EPA Method 7199.
VOC samples were collected as grab samples and SVOCs, RCRA 8 Metals, and hexavalent
chromium samples were collected by compositing 5-foot intervals. Soil borings SB-05 and SB-06
were composited after sampling VOCs from SB-06 and soil borings SB-07 and SB-08 were
composited after sampling VOCs from SB-07.
Quality control/quality assurance samples included two (2) duplicate soil samples for the above
analyses. Additionally, one (1) trip blank was submitted for each cooler containing samples
submitted for VOCs.
Table 1 provides a summary of the laboratory analyses for which each soil sample was submitted.
Soil samples were placed into laboratory -provided sample containers and stored on ice pending
shipment to a subcontract laboratory. 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.
3.3 Soil Vapor Investigation
On April 13 and 14, 2021, seven (7) temporary soil vapor monitoring points (SV-01 through SV-07)
were installed in the proposed building footprints of buildings 1, 2, 4, and 5 (Table 2). 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 soil vapor monitoring points were installed within boreholes advanced with DPT drilling
techniques to depths between 5.5 and 20 feet below land surface (bls). Drill rods were advanced
by drill rig for each boring except SV-06, which was advanced via hammer drill. The screen interval
of each point was positioned to be immediately below the proposed final elevation in cut areas.
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.) TeflonNined 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 one -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 two hours before sampling.
Prior to sampling, a shut-in (dead -head) test was conducted 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.
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 3.0-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 is to enclose the sampling point and the sampling manifold with a
shroud. The helium tracer gas is 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 and the sample tubing) were evacuated through TeflonNined
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 is considered sufficiently sealed when helium concentrations detected within the sampling
point were less than ten percent of the helium concentration in the shroud (NCDEQ DW M, 2018). The
shroud was enriched with greater than 10% helium. The concentration of helium observed within each
exterior soil vapor point was less than 25 ppm (0.025 percent) of the total shroud helium in each
exterior soil vapor point.
After completion of the helium tracer tests, the sample canister was filled using a dedicated flow
controller set to a sample rate of approximately 100 milliliters per minute. The canister vacuum
was recorded prior to and periodically during the filling period. 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 Con -Test Analytical Laboratories for analysis of VOCs via
EPA Method TO-15.
The soil gas sampling points were abandoned on April 14, 2021. The locations of the soil vapor
monitoring points are shown on Exhibit 3. Lithology logs for soil vapor points SV-01 through
SV-05 and SV-07 are included in Appendix A. A lithology log for SV-06 was not completed due
to lack of soil recovery during installation. Photographs of the soil vapor points and sampling setup
are included in Appendix B.
3.4 Investigative Derived Wastes
Soil cuttings were spread on -site or used to backfill the borings from which the cuttings originated.

Soil vapor was evaluated in four exposure units based on the proposed buildings and proposed
non-residential first floor use. A cumulative carcinogenic risk of 10-4 and a hazard index of 1.0
(cumulative non -carcinogenic risk) were used as the risk thresholds. A summary of the risk
calculator output values for each exposure unit are included in Table 5. Risk calculator input and
summary output sheets are included in Appendix D.
Soil (Exposure Unit 1)
Terracon evaluated the site soil as one cumulative exposure unit (Exposure Unit 1). Utilizing the
site -wide maximum detections for VOCs, SVOCs, and metals as the Exposure Point
Concentrations (EPCs), the risk was not exceeded for the Resident, Non -Residential Worker, or
Construction Worker Soil Combined Exposure Pathways.

Soil Vapor (Exposure Unit 2)
Exterior soil vapor points SV-01 through SV-04 were used to represent Exposure Unit 2, the
proposed location for Building 1. Based on CCUD's plans, the first floor of the building will not
contain residential areas. The maximum detections for exterior soil vapor points SV-01 through
SV-04 were used as the EPC for each constituent. The Soil Gas to Indoor Air Pathway hazard
index was calculated at a value of 1.0 and therefore exceeded for the Resident Exposure Pathway;
however, the carcinogenic risk did not exceed for the Resident Exposure Pathway. The Soil Gas
to Indoor Air Pathway risk was not exceeded for a Non -Residential Worker Exposure Pathway.
Soil Vapor (Exposure Unit 3)
Exterior soil vapor point SV-05 was used to represent Exposure Unit 3, the proposed location for
Building 5. The Soil Gas to Indoor Air Pathway risk was not exceeded for a Resident or
Non -Residential Worker Exposure Pathways.
Soil Vapor (Exposure Unit 4)
Exterior soil vapor point SV-06 was used to represent Exposure Unit 4, the proposed location for
Building 4. The Soil Gas to Indoor Air Pathway risk was not exceeded for a Resident or
Non -Residential Worker Exposure Pathways.
Soil Vapor (Exposure Unit 5)
Exterior soil vapor point SV-07 was used to represent Exposure Unit 5, the proposed location for
Building 2. The Soil Gas to Indoor Air Pathway risk was not exceeded for a Resident or
Non -Residential Worker Exposure Pathways.
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 in one exposure unit.
Based on 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. Existing data indicates that soil can be re -used without restriction on -site.
Based on the lack of a suspected source, low magnitude of the concentrations, and review
of available data of naturally occurring elements in soils of North Carolina (Boergen and
Shacklette, 1981), the detected arsenic concentrations appear to be consistent with
naturally occurring conditions.
Terracon recommends preparation of an Environmental Management Plan (EMP) for the
site and addressing the need for a HASP for construction activities. The EMP would need
to be submitted to the NCDEQ Brownfields Program for review and approval prior to any
earthmoving activities.

Terracon evaluated the exposure risk associated with soil vapor for Resident and/or Non -
Residential scenarios using analytical data from soil vapor points associated with the
approximate proposed building footprints. According to the results of the NCDEQ's risk
calculator, the carcinogenic and non -carcinogenic risks associated with the Soil Gas to
Indoor Air Pathways do not exceed for the Resident and/or Non -Residential Worker
exposure scenarios for the proposed on -site buildings with the exception of Building 1.
Building 1 exceeded the hazard index for the Resident scenario; however, the proposed
development plans do not include residential areas in the first floor of the building.
Therefore, the Resident scenario is not applicable to Building 1.
Although the risk associated with the Soil Gas to Indoor Air Pathway is acceptable for the
Non -Resident scenario for Building 1, Terracon recommends evaluating potential vapor
migration pathways once construction plans and details become available to confirm that
vapor mitigation measures are not necessary.
Terracon recommends submitting this report to the NCDEQ Brownfields Program after
receipt of an affirmative letter of eligibility.

CASE NARRATIVE
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
have 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
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
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.
rCn
MDL (dry)
Method Detection Limit.
RDL
Reported Detection Limit.
Fr
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
rq
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.
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.
J2
Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3
The associated batch QC was outside the established quality control range for precision.
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
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
have 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
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
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.
rCn
MDL (dry)
Method Detection Limit.
RDL
Reported Detection Limit.
Fr
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
rq
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
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.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.

CASE NARRATIVE
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
have 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
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
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.
rCn
MDL (dry)
Method Detection Limit.
RDL
Reported Detection Limit.
Fr
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
rq
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

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
Z-01 Compound fails the method requirement of 70-130% recovery for the LCS. Is classified by the lab as a difficult
compound and passes the in house limits of 50-150%.
