Soil Gas Sampling Report
Performance Auto Mall, Chapel Hill, NC
MCADAMS NCBP Project No. 20078-16-068
July 17, 2019
1.0 INTRODUCTION
The John R. McAdams Company, Inc. (McAdams) is pleased to submit this Soil Gas Sampling Report for
the Performance Auto Mall property located in Chapel Hill, North Carolina (herein referred to as the
"subject site"). The subject site is located between Durham -Chapel Hill Boulevard and Old Durham Road,
consists of +/- 13.93 acres of land, and is identified as North Carolina Brownfield Program (NCBP) Project
Number 20078-16-068. The subject site is depicted on Drawing 1.
1.1 Site Environmental History
Under Hendrick Automotive (and predecessors) ownership, several leaking underground storage tanks
(LUST) and leaking above ground storage tank (LAST) events were reported, including a release from a
former gasoline underground storage tank (UST) that was reported on March 28, 1995 and recorded
under Incident No. 16492. As a result of known contamination, and, prior to acquiring the property,
LG1810 obtained eligibility to participate as the Prospective Developer (PD) in the NCBP under Project No.
20078-16-68.
Excavation of contaminated soil source areas was conducted between January and March 2019 during
building demolition and earth work activities in general accordance with the Environmental Management
Plan (EMP) approved by the NCBP. This included excavation of previously identified known/suspected
areas of impacted soil and new areas of impacted soil that were identified during site construction
activities. These activities are summarized in the Interim EMP Implementation Report prepared by
McAdams, dated June 28, 2019. These activities provided a better understanding of potential vapor
intrusion (VI) risk conditions at the site.
Previous correspondence with the NCBP about site redevelopment plans considered the design and
installation of a Vapor Intrusion Mitigation System (VIMS) as a proactive measure to address VI risk from
known soil and groundwater impacts from historical automotive repair activities. Since this initial
correspondence, implementation of the EMP has been substantially completed which included the
identification and excavation of impacted source area soils under and in close proximity to the building
pad for the proposed grocery store. The source area excavation activities are likely to reduce overall VI
risk at the site.
1.2 Sampling Objectives
The objective of the soil gas sampling assessment is to evaluate if there is an unacceptable VI risk in the
building pad area for the proposed building, and as such, if design and installation of a VIMS is warranted.
Work performed as part of this assessment was conducted in general accordance with NCBP approved
Soil Gas Sampling Work Plan dated March 26, 2019.
2.0 SCOPE OF WORK
On May 30, 2019, McAdams collected twelve soil gas samples within the area of the proposed building
pad as depicted in Drawing 2. These locations were selected in general accordance with NCDEQ, Division
Page 1 of 4

NCBP Project No. 20078-16-068
July 17, 2019
of Waste Management (DWM) Vapor Intrusion Guidance (March 2018) which recommends a grid
sampling approach across the proposed building footprint biased towards potential VI sources. As shown
in Drawing 2, the potential VI sources include the former Acura oil/water separator where EMP
implementation activities included the excavation of petroleum -impacted soils. The former auto body
repair and paint buildings are also listed as potential VI sources even through EMP field screening activities
did not indicate the presence of impacted soil during site construction.
3.0 SAMPLING METHODOLOGY
3.1 Health and Safety Planning and Utility Clearing
Prior to the start of work, McAdams updated the site -specific Health and Safety Plan in general accordance
with the Occupation Safety and Health Administration (OSHA) rules (29 CFR 1910.120). To address
potential underground utilities, McAdams contacted the North Carolina 811 one -call system a minimum
of 72 hours before beginning the assessment to notify member utilities of the subsurface work.
3.2 Soil Gas Sampling
Soil gas points (SG-1 through SG-12) were installed into soil borings advanced using direct push technology
to a depth of approximately six feet BLS (Table 1). Soil was generally classified as silty clay/clayey silt. Field
notes from the sampling event are provided in Appendix A.
Soil gas sample ports were installed in each borehole by inserting and lowering a steel mesh vapor
sampling implant affixed to an inert %-inch outer diameter Teflon tube. The implant was encased with
driller's sand. Bentonite was added and hydrated with distilled water to create a seal. The borehole was
allowed to stabilize for approximately 48 hours.
Following installation, a laboratory supplied 1.0 Liter summa canister was connected to the Teflon tubing
for soil gas sample collection at each location. Prior to sample collection, a leak check was conducted using
a helium tracer compound that was introduced through a shroud over the probe, summa cannister, and
tubing while approximately four air volumes were purged from the sampling train. Following the leak
check, the summa cannister was opened and a laboratory provided flow regulator was used to maintain
flow rates less than 200 milliliters (mL) per minute. Each summa canister was closed while the canister
still had a negative pressure. Sealed canisters were shipped under chain of custody to Con -Test Analytical
Laboratory in East Longmeadow, Massachusetts for analysis of VOCs by EPA Method TO-15.
3.3 Soil Gas Sample Point Locating
A handheld GPS unit and field measurements were utilized to locate the soil gas sample points.
3.4 Soil Gas Sample Point Abandonment
Soil gas sample boreholes were abandoned using bentonite in accordance with Work Plan procedures.

3.5 Investigation Derived Waste (IDW) Management
IDW was spread in a thin layer on the ground in general accordance with the Work Plan.
4.0 SOIL GAS SAMPLE ANALYTICAL RESULTS
4.1 Laboratory Test Results
Soil gas sample results are summarized in Table 2. Because the site is being redeveloped for use as a
grocery store, test results were compared to the NCDEQ DWM Non -Residential VISLs (February 2018).
The associated Level II Quality Assurance (QA)/Quality Control (QC) analytical report is provided in
Appendix B.
McAdams evaluated the vapor intrusion risk associated with soil gas results using the May 2019 version
of the NCDEQ Risk Calculator. Risk Calculator - Summary of Risk Assessment Output is presented in
Appendix C. As summarized in Appendix C, a 1.9E-05 carcinogenic risk and a 3.8E-01 hazard index was
calculated for the soil gas to indoor air pathway for a non-residential worker.
4.2 Field Procedure QA/QC
A blind duplicate sample (DUP-1) was collected from point SG-1 and results indicate field collection,
handling, shipment, and storage procedures were adequate in producing similar duplicate and original
sample results.
5.0 FINDINGS
Overall, no constituents were detected at concentrations above Non -Residential VISLs. Provided below is
a summary of laboratory test results.
• Common petroleum -related compounds were detected at concentrations below associated Non -
Residential VISLs.
• Tetrachloroethylene (PCE) and trichloroethylene (TCE) were also detected at concentrations
below associated Non -Residential VISLs.
• Several other non -petroleum constituents were detected at concentrations below associated
Non -Residential VISLs.
• Six constituents were detected in soil gas that do not have established Non -Residential VISLs.
• Test results evaluated using the May 2019 version of the NCDEQ Risk Calculator indicate that soil
gas to indoor air pathway risk calculations were below a carcinogenic risk of 1.0E-04 and hazard
index of 1. These results indicate that an unacceptable vapor intrusion risk is not present in the
building pad area where the sampling was conducted.
6.0 CONCLUSIONS AND RECOMMENDATIONS
The objective of the soil gas sampling assessment was to evaluate if there is an unacceptable VI risk for
the proposed building, and as such, if design and installation of a VIMS is warranted. Soil gas results
indicate that there is not an unacceptable vapor intrusion risk to future site occupants. This information

suggests that VI mitigation involving the design and installation of a VIMS is not required at this time. The
NCBP has indicated that if a decision is made to not design and install at VIMS, they would require
additional sampling following building construction to confirm the test results presented in this report.
Soil gas conditions can change following construction of the proposed building. As such, the potential
exists that additional sampling activities required by the NCBP following building construction could
indicate an unacceptable vapor intrusion risk and the need to install a VIMS. To manage this risk, the PD
has elected to continue with plans to design and install a VIMS for the site as a proactive measure.
McAdams recommends submitting this report to the NCBP for their review and approval. The data
presented in this report will be used to finalize the conceptual VIMS design for NCBP review and approval
recognizing that available data indicates it unlikely that there is an unacceptable vapor intrusion risk.

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).
L-03 Laboratory fortified blank/laboratory control sample recovery is outside of control limits. Reported value for this
compound is likely to be biased on the low side.
R-01 Duplicate RPD is outside of control limits. Reduced precision is anticipated for reported result.
RL-11 Elevated reporting limit due to high concentration of target compounds.
RL-12 Elevated reporting limit due to matrix interference.
V-05 Continuing calibration verification (CCV) did not meet method specifications and was biased on the low side for
this compound.
V-31 Internal Standard is outside of control criteria for this sample. The analytes being reported for this analytical run
are not affected by this I.S. being outside of control criteria. Data validation is not affected.
V-35 Initial calibration verification (ICV) did not meet method specifications and was biased on the high side for this
compound. Reported result is estimated.
V-36 Initial calibration verification (ICV) did not meet method specifications and was biased on the high side. Data
validation is not affected since sample result was "not detected" for this compound.

concentrations in comparison to screening levels. Note that lead is not included in cumulative risk calculations.
2. * = If concentrations in groundwater exceed the NC 2L Standards or IMAC, or concentrations in surface water exceed the
NC 2B Standards, appropriate remediation and/or institutional control measures will be necessary to be eligible for a risk -based
closure.
