LIMITED SITE INVESTIGATION
PROPOSED CHICK-FIL-A #04954
201 SOUTH ESTES DRIVE
CHAPEL HILL, ORANGE COUNTY, NORTH CAROLINA
TERRACON PROJECT NO. 70217369
1.0 INTRODUCTION
Terracon Consultants, Inc. (Terracon) has completed a Limited Site Investigation (LSI) of the
proposed Chick-fil-A #04954 restaurant located at 201 South Estes Drive in Chapel Hill, Orange
County, North Carolina (site). According to client provided information and the Orange County
GIS website, the site consists of an approximate 1.3-acre portion of a 38.39-acre parcel (Orange
County Parcel ID: 9799220604) (Terracon, 2021). A topographic map is included as Exhibit 1.
The location of the site is shown on Exhibit 2.
Terracon previously completed a Phase I Environmental Site Assessment (ESA) of the site
(Terracon Project No.: 70217309, dated May 17, 2021). Terracon identified the following
recognized environmental condition (REC) associated with the site:
Based on 2020 groundwater sampling results (AECOM Technical Services of NC, Inc.
[AECOM], 2020), tetrachloroethene (PCE) was detected in groundwater in monitoring
wells near the northern site boundary associated with the American Dry Cleaners Dry -
Cleaning Solvent Cleanup Act Program (DSCA) incident. PCE was detected in monitoring
wells MW-1 (located approximately 20 feet north) and 2W-6 (located approximately 100
feet northwest) at concentrations of 0.738 micrograms per liter (pg/L) and 160 pg/L,
respectively (Exhibit 2).
Additionally, the parent tract has been granted eligibility into the North Carolina Brownfield
Program due to the on -site DSCA incident and petroleum contamination from an on -site
automotive repair garage (Chapel Hill Tire, Incident #46402). At the time of this report, a finalized
Brownfields Agreement including land -use restrictions was not in place; however, a Notice of
Residual Petroleum (NORP) was recorded for the property on January 23, 2020 due to the
petroleum contamination at the Chapel Hill Tire facility. The NORP implemented an
industrial/commercial use only land -use restriction of soil. Further land -use restrictions may be
implemented when the Brownfields Agreement is finalized.
The purpose of the investigation was to evaluate subsurface conditions in soil, groundwater, and
soil vapor with respect to the potential presence of chlorinated solvent constituents. The scope of
work is not intended to provide complete delineation or develop corrective action costs.
1.1 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.

and all relying parties.
2.0 FIELD ACTIVITIES
Field activities were conducted on July 9, 2021. Activities included boring layout, private utility
location, advancement of soil borings and temporary monitoring wells, and sampling of soil,
groundwater, and soil vapor. Prior to LSI drilling operations, public utility locators were notified via
811 call.
2.1 Private Utility Location
Terracon personnel performed a utility locate survey in the vicinity of the borings. Subsurface
utility lines were marked and cleared prior to drilling activities.

August 6, 2021 Terracon Project No. 70217369
2.2 Soil Assessment
Three soil borings (TW-01 through TW-03) were advanced via direct -push technology (DPT) and
auger rotary methods using a track -mounted GeoProbeTm drill rig in the northern portion of the
site (Exhibit 2). Soils were logged to document soil type, relative moisture content, and other
lithologic characteristics. Soil samples collected via DPT methods were screened for organic
vapors using a photoionization detector (PID). Solid stem augers were used to advance the
borings after DPT refusal occurred at depths between 7 and 12.5 feet bls. Borings were
terminated at approximately 30 feet below land surface (bls) after saturated soil conditions were
encountered. Soil boring logs are included in Appendix A.
Soil samples were selected for laboratory analysis based on PID results and/or were selected
from the depth interval with the highest potential for impact above the water table (i.e. shallow
soils). One soil sample was collected from each boring at depths between 2 and 7 feet bls or at
least five feet above the measured water table.
Each soil sample was placed into laboratory supplied containers, packed in ice, and shipped to
Pace Analytical° Laboratory (Pace) in Mt. Juliet, Tennessee and analyzed for chlorinated volatile
organic compounds (VOCs) via United States Environmental Protection Agency (USEPA) Method
8260D.
Non -dedicated sampling equipment was decontaminated using a Liquinox®/water wash followed
by a distilled water rinse prior to use and between borings. Temporary investigation locations
were backfilled with bentonite and abandoned in accordance with applicable state requirements.
2.3 Groundwater Assessment
Temporary wells (TW-01 to TW-03) were installed within the advanced soil boring locations.
Temporary well construction details are summarized on Table 1 and were constructed as follows:
Installation of a 15-foot section of 2-inch diameter, 0.010-inch machine slotted PVC
well screen;
Installation of a 2-inch diameter, threaded, flush -joint PVC riser pipe to the ground
surface; and
Addition of pre -sieved 20/40 grade silica sand for annular sand pack around the
well screen from the bottom of the boring to approximately 2-feet above the top of
the well screen.
Prior to purging the temporary wells, the depth to groundwater was measured relative to the top
of the temporary well casing and converted to depth bls. Water depths range from 8.33 to 28.03
feet bls (Table 1). The temporary monitoring wells were developed, then purged using peristaltic
pumps and disposable tubing. Low flow purging and sampling techniques (i.e., <200 milliliters
per minute) were used for each well to collect representative samples, reduce turbidity, and

minimize purge water volumes. The groundwater samples were collected after stabilization of
field parameters (e.g., pH and specific conductance). Each sample was placed into laboratory
supplied containers, packed in ice, and shipped to Pace Laboratories for analysis of chlorinated
VOCs via USEPA Method 8260D.
Drilling equipment and non -dedicated sampling equipment was decontaminated prior to use and
between borings using a Liquinox®/water wash followed by a distilled water rinse. Temporary
investigation locations were backfilled with bentonite and abandoned in accordance with
applicable state requirements.
2.4 Soil Vapor Assessment
Two temporary sub -slab soil vapor sampling points (SV-01 and SV-02) were installed within the
existing on -site building and within the proposed building location. The sub -slab soil vapor
sampling points were installed by using a handheld rotary hammer to drill a hole through the
concrete floor slab of the building and inserting a sub -slab soil vapor sampling port (VaporPinTM)
into the hole. Each soil vapor point was allowed to equilibrate for a minimum of 2 hours after
installation and leak tested prior to sampling to ensure that the points were properly sealed, thus
preventing indoor air from entering the point during sampling. Sampling locations are displayed
in Exhibit 2. Sampling methodology for the shallow soil vapor sampling is described in the
following paragraphs.
Shut -In Test
Prior to connection of the sampling equipment to the soil vapor sample point, a shut-in (dead-
head) test was conducted to check for leaks in the aboveground purge/sampling manifold. A
sampling train consisting of a batch certified 1-liter Summa canisterfor sample collection (sample
canister) connected to a critical orifice flow restrictor (flow controller). The sampling train influent
was capped, the sampling canister remained closed, and a negative pressure reading of at least
15 inches of mercury was induced on the sampling train pressure gauge. The pressure gauge
was then observed for losses in vacuum. If there was an observable loss of vacuum, the fittings
were adjusted until the vacuum in the sample train did not noticeably dissipate.
Helium Tracer Test
Following the shut-in test, the purge/sampling train was connected to the soil gas sampling point
and a helium tracer gas leak test was conducted. The tracer gas serves as a quality
assurance/quality control (QA/QC) method to verify the integrity of the sampling train seal to the
sample point. An MGD-2002 helium detector was used to verify the presence and concentration
of tracer gas.
The protocol for using a tracer gas is to enclose the sampling train and sample point outlet with a
shroud, enrich the shroud atmosphere with at least 10 percent helium. The purging device
(syringe and/or hand pump) was situated outside of the shroud connected with the sampling train
by Teflon° lined tubing running through the shroud. A minimum of three volumes was evacuated

from the sample point. Purged soil gas was screened for helium to assess for leaks in the
sampling point seal and with a PID to assess for VOCs. The shroud helium concentration and the
helium concentration in the purged soil vapor was documented after each volume purged.
The sampling train and vapor monitoring point connection was considered to be sufficiently sealed
when helium concentrations were less than ten percent of the helium concentration in the shroud.
Each point had a concentration of less than ten percent of the helium concentration in the shroud.
Soil Vapor Sample Collection
Following the helium leak test, the valve to the purge device was closed and the sample canister
valve was opened to initiate collection of soil vapor for laboratory analysis. The sample was
collected at a flow rate of approximately 200 milliliters per minute. The sample canister valve was
closed when the gauge measured approximately five to nine inches of mercury (Hg) vacuum. The
canisters were packaged and delivered along with chain of custody documentation to Pace for
analysis of chlorinated VOCs via USEPA Method TO-15.
3.0 RESULTS
Soils at the site were observed to consist primarily of sand and silt/siltstone. Groundwater at the
site was inferred to flow to the east based on topography. Groundwater elevations and a true
groundwater flow direction at the site were not determined. Groundwater flow at the former
American Drycleaners facility, located approximately 200 feet northwest of the site, was estimated
to flow to the southeast (AECOM, 2020). Site lithology was documented in boring logs provided
in Appendix A. Site photographs documenting field activities and site conditions are provided in
Appendix B. The laboratory analytical reports are provided in Appendix C.
3.1 Soil Analytical Results
Soil sample analytical results were compared with the North Carolina Department of
Environmental Quality (NCDEQ) Residential and Industrial/Commercial Preliminary Soil
Remediation Goals (PSRGs).
Results of soil sample analytical results are as follows:
Cis-1,2-dichloroethene (cis-1,2-DCE) was detected below its Residential and
Industrial/Commercial PSRG in TW-03.
Additional chlorinated VOCs were not detected in the soil samples.
The soil analytical results are summarized in Table 2.

3.2 Groundwater Analytical Results
Groundwater sample analytical results were compared with North Carolina Administrative Code
2L Groundwater Quality Standards (2L standards). Results of groundwater sample analytical
results are as follows:
cis-1,2-DCE, tetrachloroethene (PCE), trichloroethene (TCE), and vinyl chloride were
detected above the 2L standards in TW-03.
cis-1,2-DCE and trans- 1,2-dichloroethene (trans-1,2-DCE) were detected below the 2L
standards TW-02 and TW-03, respectively.
Additional chlorinated solvent VOCs were not detected in the groundwater samples.
The groundwater analytical results are summarized on Table 3.
3.3 Soil Vapor Analytical Results
Soil vapor sample analytical results were compared with NCDEQ Residential and Non -Residential
Sub -Slab Soil Gas Screening Levels (SGSLs) and are summarized as follows:
None of the chlorinated VOCs analyzed were reported to be above the Non -Residential
SGSL.
Chloroform and tetrachloroethene were detected above the Residential SGSL, but not
above the Non -Residential SGSL in SV-02.
Additional chlorinated solvent VOCs were detected below the Residential and Non -
Residential SGSLs in SV-01 and SV-02.
Soil vapor analytical results are summarized on Table 4.
4.0 FINDINGS AND CONCLUSIONS
The findings and conclusions of this investigation are as follows:
The site is part of a larger parcel (parent tract) that has been impacted by a release of dry-
cleaning solvents and petroleum. A NORP has been recorded for the petroleum release
incident (Incident #46402) and implemented an industrial/commercial use only land -use
restriction for on -site soil. The parent tract has also been granted eligibility into the NC
Brownfield Program. When a finalized Brownfields Agreement is in place, it will likely include
further land -use restrictions on the property.
Chlorinated VOCs were not detected above the Residential or Industrial/Commercial
PSRGs in the soil samples. Based on the depth to groundwater, impacted soils are not
anticipated within the shallow onsite soils likely to be disturbed as part of construction.

Based on the NORP, industrial/commercial use only land -use restrictions were implemented
for on -site soil; however, a soil management plan is not in place for the property.
Cis-1,2-DCE, PCE, TCE, and vinyl chloride were detected in groundwater samples above
the 2L standards in TW-03. Additional chlorinated VOCs were not detected above the 2L
standards in the groundwater samples.
Chloroform and PCE were detected in sub -slab soil gas samples above the Residential
SGSL, but not above the Non -Residential SGSL in SV-02. The chloroform likely is
associated with potable water use and is not considered to be a constituent of concern.
Additional chlorinated VOCs were not detected above the Residential or Non -Residential
SGSL in the soil vapor samples.
5.0 RECOMMENDATIONS
Based on the results of this investigation, Terracon recommends the following:
Based on the observed site groundwater and soil vapor concentrations, Terracon
recommends that the property owner report the detections to the NCDEQ Brownfields
Program. Since the site is located on a NCDEQ Brownfields Program property, an
approved Environmental Management Plan may be required by NCDEQ prior to
construction activities, which could include installation of a vapor mitigation system or
further soil vapor evaluation based on NCDEQ Brownfields Program comment.
Terracon does not recommend further assessment of groundwater or soil vapor based
on the proposed commercial use of the site without input from the NCDEQ Brownfields
Program.

CASE NARRATIVE
FP
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
FC
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
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
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.
RDL
Reported Detection Limit.
rCn
Rec.
Recovery.
RPD
Relative Percent Difference.
FSr
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
rqC
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
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
FAI
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
SC
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
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.

CASE NARRATIVE
FP
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
FC
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
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
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).
rCn
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.
