1.0 Introduction and Background

On behalf of White Point Partners, LLC, Hart & Hickman, PC (H&H) has prepared this report to
document assessment activities completed at the Dilworth Auto Service Brownfields property
(Brownfields Project No. 24051-20-060) located at 120 E. Kingston Avenue; 1700, 1708, 1714,
1720, and 1728 South Boulevard; and 101, 105, and 115 East Boulevard in Charlotte,
Mecklenburg County, North Carolina (Site). The Site is comprised of seven contiguous parcels
of land that total approximately 2.3 acres and an alleyway which extends southwest from 120 E.
Kingston Avenue to East Boulevard. A Site location map is provided as Figure 1, and Site
features are depicted on Figure 2.

The Site was developed with single-family residences and ancillary structures as of at least 1905.
Commercial development began at the Site in the 1920s and continued until the late 1990s.
Historical commercial facilities on the Site have included a lumber warehouse, gas stations,
automotive repair shops, and dry cleaners.

The Site is currently developed with a pharmacy/convenience store and three vacant commercial
buildings. Planned redevelopment of the Brownfields property includes demolition of the
existing buildings and construction of commercial and multi-family residential buildings.

To address potential environmental concerns associated with the Site, the Prospective Developer
(PD) elected to enter the Site into the North Carolina Department of Environmental Quality
(DEQ) Brownfields Program and received eligibility in a letter dated October 30, 2020.

In November 2020, H&H performed soil, groundwater, and exterior soil gas sampling and
methane screening activities at the Site to evaluate potential areas of environmental concern
associated with historical on-Site operations. The assessment sample locations are depicted on
Figure 2. A summary of the results of the assessment is provided below.

Soil
 Laboratory analytical results indicated the presence of several volatile organic
compounds (VOCs) in soil that exceeded DEQ Preliminary Soil Remediation Goals
(PSRGs) in the vicinity of the former gas stations in the northeastern portion of the Site.
Specifically, ethylbenzene and naphthalene concentrations exceeded the Residential
PSRGs in SB-1 (8-10); a naphthalene concentration exceeded the Protection of
Groundwater and Industrial/Commercial PSRGs in SB-1 (8-10); benzene concentrations
exceeded the Protection of Groundwater PSRG in SB-1 (8-10) and SB-2 (8-10); and a
xylenes concentration exceeded the Protection of Groundwater PSRG in SB-1 (8-10).
 The concentration of tetrachloroethylene (PCE) slightly exceeded the Protection of
Groundwater PSRG in SB-10 (1-3), located in the northeastern portion of the Site.
 The polycyclic aromatic hydrocarbon (PAH) 2-methylnaphthalene in SB-1 (8-10) was
detected at a concentration above the Protection of Groundwater PSRG.
 Lead was detected at a concentration above the Protection of Groundwater and
Residential PSRGs in soil sample SB-6 (1-3), located near a former automotive repair
shop in the northeastern portion of the Site.
 Hexavalent chromium was detected at concentrations above the Residential PSRG in
multiple soil samples. However, based on the relatively low-level detections of
hexavalent chromium, the even distribution of hexavalent chromium detections across the
Site, and the lack of obvious on-Site sources of hexavalent chromium based on historical
operations, the detected hexavalent chromium concentrations are likely naturally
occurring.
 Arsenic was detected in several soil samples collected at the Site at concentrations above
the Residential and Industrial/Commercial PSRGs, and selenium was detected in several
soil samples collected at the Site at concentrations which exceeded the Protection of
Groundwater PSRG. The detected arsenic and selenium concentrations appear to be

esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
naturally occurring based on published background data, the lack of obvious sources of
selenium based on historical operations at the Site, and prior soil data for the South End
District of Charlotte.
 The results of risk calculations using combined Site soil data indicated that the calculated
cumulative risks are below acceptable risk levels for the residential, non-residential
worker, and construction worker exposure scenarios.

Groundwater
 Laboratory analytical data indicated that the VOCs benzene, 1,2-dichloroethane,
ethylbenzene, isopropylbenzene, 2-hexanone, methyl isobutyl ketone, methyl tert-butyl
ether, naphthalene, toluene, and xylenes were detected above the respective North
Carolina 2L Groundwater Standards (2L Standards)/Interim Maximum Allowable
Concentrations (IMACs) in samples TMW-1/TMW-Dup. Benzene was also detected in
groundwater samples TMW-2 and TMW-7 above the 2L Standard. Groundwater
samples TMW-1/TMW-Dup and TMW-2 were collected near former gas stations and an
automotive repair shop in the northeastern portion of the Site, and sample TMW-7 was
collected in the southern portion of the Site near a former on-Site gas station and
downgradient of an off-Site gas station.
 PCE was detected at a concentration slightly above the 2L Standard in groundwater
sample TMW-5, which was collected in the northwestern portion of the Site and
downgradient of the former dry cleaner at 113/115 East Boulevard.
 Results of semi-VOC (SVOC) analysis indicated the presence of 2-methylnaphthalene
and naphthalene at concentrations above the 2L Standards in samples TMW-1/
TMW-Dup.
 No metals were detected in the seven temporary well samples at concentrations above the
2L Standards.

Vapor Intrusion (VOCs)
 Chloroform, ethylbenzene, and naphthalene were detected at concentrations exceeding
the June 2021 DEQ Division of Waste Management (DWM) Residential Sub-Slab and
Exterior Soil Gas Screening Levels (SGSLs) but below Non-Residential SGSLs in
4

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-011 dilworth auto service phase ii
esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
sample SG-1. Chloroform and naphthalene were also detected above Residential SGSLs
in sample SG-11. Low concentrations of chloroform above the Residential SGSL were
also identified in samples SG-2 and SG-8. The concentration of hexane reported in the
SG-3 duplicate sample (SG-Dup-11/20/20) exceeded the Residential SGSL. Benzene
and chloroform concentrations detected in samples SG-4 and SG-6 exceeded the
Residential SGSLs but were below the Non-Residential SGSLs. The concentration of
benzene detected in sample SG-5 exceeded the Residential SGSL.
 Cumulative risk calculations using the highest concentration of each detected compound
in any soil gas sample showed that the non-carcinogenic and carcinogenic risk levels
were below acceptable risk levels for both residential and non-residential exposure
scenarios.

Methane Assessment
 Results of methane gas screening activities conducted at each of the 11 soil gas sample
locations indicated that methane is present at trace levels in SG-3. Methane
concentrations measured in SG-3 (0.6% to 0.8% by volume) are not within the explosive
limits, and differential pressure measurements collected from SG-3 indicate that the
localized, trace levels of methane gas are stable. Therefore, methane vapor intrusion into
the proposed Site buildings does not appear to be a significant concern.

Results of the November 2020 assessment activities were provided to the DEQ Brownfields
Program in a Brownfields Assessment Report dated February 1, 2021. In an email dated
April 16, 2021, the DEQ Brownfields Program requested additional soil and soil gas assessment
activities at the Site. H&H prepared a Brownfields Assessment Work Plan (Work Plan) to
complete DEQ-requested assessment activities at the Site. The Work Plan received DEQ
approval on June 22, 2021.

In August 2021, H&H completed assessment activities to further evaluate potential soil impacts
at a former underground storage tank (UST) basin the southern portion of the Site and former
automotive repair shops which may have used hydraulic lifts in the central and northeastern
portions of the Site. In addition, soil gas assessment activities were conducted at a former gas

station in the northeastern portion of the Site, where the highest levels of petroleum-related
groundwater contamination were identified. H&H also conducted receptor survey activities in
the area surrounding the Site. A summary of the recently completed Brownfields assessment
activities is provided in the following sections.

2.0 Brownfields Assessment Activities

The assessment activities were performed in general accordance with the DEQ-approved Work
Plan, the DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup
of Contaminated Sites (Guidelines) dated July 2021, the DEQ DWM Vapor Intrusion Guidance
(VI Guidance) dated March 2018, and most recent versions of the EPA Region IV Lab Services
and Applied Sciences Division (LSASD) Field Branches Quality System and Technical
Procedures guidance.

Prior to conducting field activities, H&H contacted North Carolina 811, the public utility locator
service, to mark subsurface utilities at the Site. H&H also contracted with a private utility
locator to identify locations of subgrade utilities that may not have been marked by the public
locator. Additionally, the soil boring locations were hand cleared to a depth of approximately
5 ft below the ground surface (bgs) using a decontaminated stainless-steel hand auger prior to
use of mechanical drilling equipment to further screen the boring locations for the presence of
potential subsurface utilities.

A summary of receptor survey results is provided in Section 3.0; soil assessment activities are
summarized in Section 4.0; soil gas assessment activities are summarized in Section 5.0; quality
assurance and quality control information is summarized in Section 6.0, and conclusions based
on results of the Brownfields assessment activities are included in Section 7.0.

3.0 Receptor Survey

On August 2, 2021, H&H conducted receptor survey activities at the Site and nearby area.
Receptor survey activities included a pedestrian and vehicular survey to obtain information about
land use, water supply, basements, underground utilities, drains, and surface water bodies located
within a 1,500-ft radius of the Site. H&H also utilized the online Mecklenburg County Well
Information System and DEQ Source Water Assessment Program (SWAP) geographic
information system map to identify potential potable water sources for properties located within
a 1,500-ft radius of the Site. In addition, H&H identified the locations of main underground
utilities based on field observations and online resources, and land use and zoning in the area of
the Site were identified using available Mecklenburg County online resources. A receptor
survey map is included as Figure 3, and a copy of the completed DEQ Brownfields Property
Receptor Survey form is provided as Appendix A. A discussion of the receptor survey activities
is provided in the following sections.

Zoning
The Site is zoned mixed-use development district (MUDD-O). Properties to the north are zoned
transit oriented development (TOD-UC and TOD-MO) and residential (R-5 and UR-2-CD).
Properties east of the Site are zoned transit oriented development (TOD-UC and TOC-NC) and
residential (R-5 and R-22MF). Zoning south of the Site consists of business (B-1), office (O-2),
residential (R-5 and R-22MF), transit oriented development (TOD-RCD, TOD-NC, TOD-RO,
and TOD-MCD), and mixed-use (UMUD). Properties west of the Site are generally zoned for
mixed-use (UMUD) and transit oriented development (TOD-MO and TOD-UC). Zoning in the
area of the Site is shown in Figure 3.

Municipal Water Availability
Municipal water supplied by Charlotte Water is available to the Site and surrounding area. H&H
did not identify sources of public drinking water within 1,500 ft of the Site based on the review
of information available on Mecklenburg County Well Information System maps and the DEQ
SWAP geographic information system map. The City of Charlotte and Mecklenburg County
obtain their water from Lake Norman and Mountain Island Lake. Mountain Island Lake is the
7

esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
closest drinking water source and is located approximately 10 miles northwest of the Site.

H&H reviewed the service area map published by Mecklenburg County which indicated that
municipal water is available to the Site and the surrounding area within a 1,500-ft radius of the
Site. Additionally, H&H observed municipal water meters at the Site and surrounding properties
during receptor survey reconnaissance activities.

Water Supply Wells
H&H conducted a pedestrian and vehicular survey of properties within a 1,500-ft radius of the
Site to identify potential water supply wells. H&H also utilized Mecklenburg County Well
Information System maps and DEQ SWAP geographic information system maps to identify
potential potable water supply wells located within a 1,500-ft radius of the Site. No water supply
wells used for any purpose were identified within 1,500 ft of the Site.

Surface Water Bodies
An unnamed tributary of Irwin Creek is located approximately 1,050 ft northwest of the
Brownfields property. Based on the North Carolina DEQ classification system, Irwin Creek is a
Class C surface water body. A Class C surface water body is defined as “waters protected for
uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including
propagation, survival and maintenance of biological integrity, and agriculture. Secondary
recreation includes wading, boating, and other uses involving human body contact with water
where such activities take place in an infrequent, unorganized, or incidental manner”.

Subsurface Structures
H&H contacted North Carolina 811, the public utility locator, to mark subsurface utilities at the
Site. H&H also conducted a visual reconnaissance in the area to identify potential subsurface
structures within 1,000 ft of the subject Site. H&H observed evidence of subsurface utilities
including sanitary sewer, municipal water, communications, electrical, and natural gas on the
Site and nearby adjacent properties. Aside from the eastern portion of the on-Site building at
1708 South Boulevard (proposed to be demolished), H&H did not observe structures with
potential basements within a 1,000-ft radius of the Site during visual reconnaissance.

4.0 Soil Assessment Activities

On August 2, 2021, H&H contracted with Mid South Environmental, Inc. (Mid South) to
advance three (3) soil borings for collection of soil samples to evaluate for potential impacts in
areas of potential environmental concern. Soil boring locations are depicted on Figure 2 and are
described further as follows:
 SB-14A was advanced adjacent to former soil sample location SB-14 near the center of
the Site in the area of a former automotive repair shop which may have historically used
hydraulic lifts;
 SB-18 was advanced between previous soil borings SB-5 and SB-6 in the northeastern
portion of the Site in the area of a former automotive repair shop which may have
historically used hydraulic lifts; and
 SB-19 was advanced in the southern portion of the Site in the area of a former gasoline
UST basin.

Details of the soil sampling activities and results are provided in the following sections.

4.1 Soil Sampling Methodologies

Mid South utilized a decontaminated stainless-steel hand auger and a track-mounted direct-push
technology (DPT) drill rig to advance the three soil borings. Borings SB-14A and SB-18 were
advanced to a depth of 10 ft bgs to screen soils that are assumed to be at least as deep as potential
former hydraulic lifts. Boring SB-19 was advanced to a depth of 15 ft bgs, which is assumed to
be at least as deep as the bottom of the former gasoline USTs. Continuous soil samples were
collected from the center of the hand auger bucket or acetate-lined macrocore sleeve at each soil
boring location. The soil samples were logged for lithologic description, observed using visual
and olfactory methods for obvious evidence of staining or unusual odors, and screened for the
presence of volatile organic vapors using a calibrated photoionization detector (PID). Boring
logs including lithologic descriptions and field screening results are provided in Appendix B.
9

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-011 dilworth auto service phase ii
esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
Field screening did not identify obvious evidence of potential impact in the soil screened from
boring SB-14A. Therefore, a soil sample was collected for laboratory analysis from a depth of 5
to 7 ft bgs, as proposed in the Work Plan. Field screening indicated slightly elevated PID
readings at a depth of approximately 2 to 3 ft bgs in boring SB-18, and a sample was
subsequently collected from that depth interval for laboratory analysis. Odor, black staining, and
an elevated PID reading were observed in soil at a depth of 11 to 13 ft bgs at boring SB-19, and a
sample was collected from that depth for laboratory analysis.

Soil samples selected for laboratory analysis were collected directly into dedicated laboratory-
supplied sample containers, labeled with the sample identification, date, time, and requested
analysis, and placed in a laboratory-supplied cooler with ice. The soil samples were submitted to
Con-Test, a Pace Analytical Laboratory (Con-Test) in East Longmeadow, Massachusetts under
standard chain-of-custody protocols for analysis. Samples SB-14A (5-7) and SB-18 (2-3) were
submitted for analysis of polychlorinated biphenyls (PCBs) by EPA Method 8082. Sample
SB-19 (11-13) was analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270,
and Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium by
EPA Methods 6020/7471/7199. Duplicate soil samples Soil-Dup-1 and Soil-Dup-2 were also
collected from borings SB-19 and SB-18, respectively, and analyzed for the same parameters as
parent samples.

Following soil sampling activities, the soil borings were properly abandoned and the ground
surface was repaired to match approximate pre-drilling conditions. The soil sample locations
were also estimated using a hand-held global positioning system (GPS) unit.

4.2 Soil Sampling Analytical Results

A summary of the soil sample analytical results is presented in Table 1, and the laboratory
analytical report and chain-of-custody record are provided in Appendix C. The laboratory
analytical results were compared to DEQ Residential and Industrial/Commercial PSRGs (June
2021). In addition to the PSRGs, metals results were compared to background metals
concentrations in North Carolina soils as published in Elements in North American Soils by
Dragun & Chekiri dated 2005.
10

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/white point partners (wpp)/wpp-011 dilworth auto service phase ii
esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
As shown in Table 1, laboratory analytical results did not indicate detectable concentrations of
PCBs in samples SB-14A, SB-18, and duplicate sample Soil-Dup-2.

Analytical results indicated the presence of the VOCs ethylbenzene (52 milligrams per kilogram
[mg/kg]) and naphthalene (15 mg/kg) at concentrations above the DEQ Residential and
Industrial/Commercial PSRGs in the SB-19 duplicate sample (Soil-Dup-1). Benzene (4.6
mg/kg) and 1,2,4-trimethylbenzene (120 mg/kg) were detected above the Residential PSRGs of
1.2 mg/kg and 63 mg/kg, respectively, in sample Soil-Dup-1. The concentrations of
ethylbenzene (13 mg/kg) and naphthalene (3.6 mg/kg) detected in parent sample SB-19 exceed
the Residential PSRGs of 6.1 mg/kg and 2.1 mg/kg, respectively. No other VOCs were detected
at concentrations above PSRGs in soil sample SB-19 or its duplicate, Soil-Dup-1.

The SVOC naphthalene was detected in SB-19 and Soil-Dup-1 at concentrations up to
4.1 mg/kg, which exceeds the Residential PSRG of 2.1 mg/kg.

As expected, several metals were detected at concentrations above laboratory method detection
limits in soil samples SB-19 and Soil-Dup-1. Concentrations of arsenic (1.5 mg/kg), barium (up
to 120 mg/kg), total chromium (up to 18 mg/kg), hexavalent chromium (up to 0.729J mg/kg),
lead (up to 9.5 mg/kg), mercury (0.026J mg/kg), selenium (up to 0.26J mg/kg), and silver (up to
0.11J mg/kg) were reported in SB-19 and/or its duplicate. The “J-flag” for certain metals
detections indicates an estimated concentration that is between the laboratory method detection
limit but below the laboratory reporting limit. The concentrations of arsenic detected in SB-19
and its duplicate slightly exceed the Residential PSRG of 0.68 mg/kg, but are below the
published average background level for North Carolina soils of 4.8 mg/kg. Therefore, the
arsenic detections are likely naturally occurring. The hexavalent chromium concentrations in the
samples slightly exceed the Residential PSRG of 0.31 mg/kg, but are generally consistent with
hexavalent chromium concentrations identified in soil across the Site during previous assessment
activities. Based on the relatively low-level and even distribution of hexavalent chromium
detections across the Site, and the lack of obvious on-Site sources of hexavalent chromium based
on historical operations, the detected hexavalent chromium concentrations are likely naturally
occurring. No other metals were detected at concentrations above the PSRGs.

5.0 Soil Gas Assessment Activities

On August 2, 2021, H&H contracted with Mid South to install three (3) exterior soil gas
monitoring points (SG-12, SG-13, and SG-14) in the area of former gas stations in the
northeastern portion of the Site (near the highest levels of petroleum-related impacts to
groundwater) to evaluate the potential for structural vapor intrusion into the mixed-use retail and
apartment building proposed for construction in the eastern portion of the Site. The soil gas
sample locations are shown in Figure 2 and are described further as follows:
 SG-12 was installed in a former UST basin;
 SG-13 was installed near former dispenser islands; and
 SG-14 was installed near a former gas station building.

Exterior soil gas sampling methodology and results are provided in the following sections.

5.1 Soil Gas Sampling Methodologies

Mid South utilized a decontaminated stainless-steel hand auger and DPT rig to advance the soil
gas monitoring point borings to a depth of 7 ft bgs. Continuous soil samples were collected from
the center of the hand auger bucket or acetate-lined macrocore sleeve at each soil gas monitoring
point boring location. The soil samples were logged for lithologic description, observed using
visual and olfactory methods for obvious evidence of staining or unusual odors, and screened for
the presence of volatile organic vapors using a calibrated PID. Field screening results indicated
an odor and elevated PID readings in the soil samples collected at depths ranging from
approximately 4 ft bgs to 7 ft bgs in borings SG-13 and SG-14. No obvious evidence of
significant impact was identified during advancement of boring SG-12. Boring logs including
lithologic descriptions and field screening results are provided in Appendix B.

A 6-inch stainless-steel vapor implant screen point fitted with ¼-inch Teflon® tubing was placed
at the bottom of each borehole. Filter sand was placed from the base of the boring to
approximately 6 inches above the screened interval. The sampling points were completed by
placing hydrated bentonite from the top of the filter sand to the ground surface. The Teflon®
12

esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
sample tubing at each soil gas monitoring point was connected to a laboratory-supplied airflow
regulator and 1-Liter Summa canister using a brass nut and ferrule assembly to create an air tight
seal. Please note that a duplicate soil gas sample (SG-Dup) was collected from the SG-14
sampling location using a laboratory-supplied “T sampler”, which allows for collection of two
soil gas samples from a single sampling point simultaneously.

Once the sample train was assembled and prior to sampling, a leak check was conducted at each
soil gas monitoring point by constructing a shroud around the sampling system and flooding the
air within the shroud with helium gas. Helium concentrations inside the shroud were measured
using a calibrated helium gas detector and maintained at concentrations of approximately 20% to
30% for the duration of the leak check. Using a syringe and three-way valve, each soil gas
monitoring point was purged a minimum of three sample train volumes of air and a sample was
collected from the sample tubing into a Tedlar bag outside the shroud. The sample was analyzed
using the helium gas detector to confirm helium concentrations in the sample were less than 10%
of helium concentrations measured within the shroud. The purge volume for each soil gas
monitoring point was calculated to include the screen, tubing, and sand pack. Each of the soil
gas monitoring points passed the leak check criteria.

Following successful field leak checks, the intake valves on the airflow regulators were fully
opened to begin collection of the soil gas samples into the Summa canisters. The airflow
regulators were calibrated by the laboratory to allow the Summa canisters to fill at a rate of
approximately 100 mL/min. Vacuum readings from the Summa canisters were recorded prior to
and following the sampling period to ensure adequate sample volumes were collected. A
vacuum was maintained within the canisters at the conclusion of the sampling event as indicated
on the laboratory chain-of-custody record provided in Appendix C. A soil gas sampling field
form is included as Appendix D.

Upon collection of the samples, the Summa canister valves were closed, and the regulators were
disconnected from the canisters. The canisters were placed in a laboratory-supplied shipping
container, properly labeled, and shipped under standard chain-of-custody protocols to Con-Test
for analysis of VOCs by EPA Method TO-15.

esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
Following sample collection, the screen implants with attached tubing were removed, the borings
were properly abandoned, and the surfaces were repaired similar to pre-drilling conditions.
Additionally, the soil gas sample locations were estimated using a hand-held GPS unit.

5.2 Soil Gas Analytical Results

A tabular summary of the soil gas sample analytical results is provided as Table 2. The
laboratory analytical report and chain-of-custody record are provided in Appendix C. The
analytical results were compared to DEQ DWM Residential and Non-Residential Vapor
Intrusion SGSLs dated June 2021.

Soil gas laboratory analytical results indicate that several compounds were detected at
concentrations above the laboratory method detection limits in each sample. Multiple
petroleum-related compounds were detected at concentrations above Residential and Non-
Residential Vapor Intrusion SGSLs in the soil gas samples.

A summary of VOC detections above the SGSLs is provided as follows:

 Benzene (96 micrograms per cubic meter [µg/m3]) and ethylbenzene (130 µg/m3) were
detected in SG-12 at concentrations that exceed the Residential SGSLs of 12 µg/m3 and
37 µg/m3, respectively, but are below the Non-Residential SGSLs.
 Concentrations of benzene (up to 4,400 µg/m3), ethylbenzene (up to 44,000 µg/m3),
naphthalene (up to 2,700 µg/m3), 1,2,4-trimethylbenzene (up to 34,000 µg/m3), 1,3,5-
trimethylbenzene (up to 9,200 µg/m3), and m&p-xylenes (up to 48,000 µg/m3) were
detected in SG-13, SG-14, and the SG-14 duplicate (SG-Dup) at concentrations that
exceed the Residential and Non-Residential SGSLs.
 1,2-Dichloroethane (up to 95 µg/m3) and o-xylene (up to 16,000 µg/m3) were detected in
SG-14 and its duplicate at concentrations above the Residential and Non-Residential
SGSLs. The concentration of o-xylene (2,600 µg/m3) detected in SG-13 also exceeds the
Residential SGSL but is below the Non-Residential SGSL.

 Heptane (up to 28,000 µg/m3) and hexane (up to 29,000 µg/m3) were detected in SG-13,
SG-14, and the SG-14 duplicate at concentrations that exceed the Residential SGSLs but
are below the Non-Residential SGSLs.

5.3 Vapor Intrusion Risk Evaluation

The DEQ DWM SGSLs are very conservative and based upon a lifetime incremental cancer risk
(LICR) of 1.0 x 10-6 for potential carcinogenic effects and a Hazard Quotient (HQ) of 0.2 for
potential non-carcinogenic effects. The DEQ and EPA acceptable risk level for potential
carcinogenic risks is a cumulative LICR of 1.0 x 10-4 or less, and the acceptable risk level for
non-carcinogenic risks is a hazard index (HI) of 1.0 or less. The HI is the sum of HQs for each
detected compound.

H&H utilized the DEQ Risk Calculator (June 2021) assuming both a residential and non-
residential land use scenario to further evaluate potential cumulative risks for the soil gas to
indoor air vapor intrusion pathway. H&H calculated the cumulative risks associated with
compounds detected in each individual soil gas sample. For SG-14, the cumulative risk was
calculated using the highest concentration of each detected compound in the parent or duplicate
sample. Risk calculator results for each soil gas sample are provided in the tables below:

Risk Calculator Results – Residential Land Use Scenario
Sample ID Carcinogenic Risk Hazard Index Risk Exceeded?
SG-12 1.2 x 10-5 0.55 No
SG-13 2.5 x 10-3 70 Yes
SG-14 / SG-Dup 6.8 x 10-4 59 Yes

Risk Calculator Results – Non-Residential Land Use Scenario
Sample ID Carcinogenic Risk Hazard Index Risk Exceeded?
SG-12 8.9 x 10-7 0.044 No
SG-13 1.9 x 10-4 5.6 Yes
SG-14 / SG-Dup 5.2 x 10-5 4.7 Yes

esa & brownfields/brownfields assessment/final to deq/24051-bf assessment report_dilworth auto service.doc
As shown in the above tables, risk calculator results using data for samples SG-13 and SG-14
indicate carcinogenic and/or non-carcinogenic risk levels above acceptable risk levels under
residential and non-residential land use scenarios. Cumulative risk calculator results using data
for sample SG-12 did not indicate exceedances of acceptable risk levels under a residential or
non-residential land use scenario. Based on the results of soil gas sampling and risk calculations,
there is a potential vapor intrusion concern for the proposed mixed-use building in the eastern
portion of the Site. Copies of the DEQ Risk Calculator input/output forms are provided in
Appendix E.

6.0 Quality Assurance – Quality Control

For quality assurance and quality control purposes (QA/QC), non-dedicated equipment and tools
were decontaminated prior to use at each boring or sampling location or following exposure to
soil. To evaluate the reproducibility of the sample results, H&H collected two duplicate soil
samples and one duplicate soil gas sample for laboratory analysis.

Duplicate soil samples were collected directly into individual sample containers using sampling
methodologies described in previous sections. For soil gas, the duplicate sample was collected
concurrently with the parent sample using a laboratory-supplied T-fitting which allows for
collection of two samples from one location simultaneously. The samples were analyzed for the
same parameters as the parent samples, and the analytical results were compared with those of
the parent sample. The analytical results of the parent sample and the duplicate sample were
used to evaluate the cumulative precision because of the limitations of the analytical method,
sample matrix, and sample collection techniques. Duplicate samples were collected as follows:
 One duplicate soil sample was collected from soil boring SB-19 (Soil-Dup-1);
 One duplicate soil sample was collected from soil boring SB-18 (Soil-Dup-2); and
 One duplicate soil gas sample was collected from soil gas monitoring point SG-14 (SG-
Dup).

The results of the duplicate samples collected for each sample medium are presented in the
summary tables. As shown in Tables 1 and 2, the duplicate sample results for the soil and soil
gas samples did not indicate significant variability from results of the parent samples.

7.0 Summary and Conclusions

H&H has completed Brownfields assessment activities at the Dilworth Auto Service Brownfields
property located at 120 E. Kingston Avenue; 1700, 1708, 1714, 1720, and 1728 South
Boulevard; and 101, 105, and 115 East Boulevard in Charlotte, North Carolina. The assessment
activities were conducted in accordance with the DEQ-approved Work Plan dated May 11, 2021.
Brownfields assessment activities included collection of three soil samples and three exterior soil
gas samples for laboratory analysis to further evaluate environmental impacts at the Site. In
addition, receptor survey activities were completed to obtain information regarding land use,
water supply, basements, underground utilities, drains, and surface water bodies in the vicinity of
the Site. A brief summary of the Brownfields assessment activities is provided below.

 Results of receptor survey activities did not identify private water supply wells within
1,500 ft of the Site. Municipal water is provided to the Site and surrounding area by
Charlotte Water. Aside from an on-Site basement in the eastern portion of the building at
1708 South Boulevard (proposed to be demolished), H&H did not observe basements in
structures located in the vicinity of the Site. An unnamed tributary to Irwin Creek (Class
C surface water body) is located approximately 1,050 ft northwest of the Brownfields
property.

 Laboratory analytical results for soil samples SB-14A and SB-18, which were collected
in the area of former automotive repair shops, did not indicate detectable concentrations
of PCBs. Soil samples collected in the area of a former gasoline UST basin in the
southern portion of the Site (SB-19 and/or its duplicate Soil-Dup-1) indicated
concentrations of ethylbenzene and naphthalene that exceed the Residential and
Industrial/Commercial PSRGs. Concentrations of benzene, 1,2,4-trimethylbenzene,
arsenic, and hexavalent chromium exceed the Residential PSRGs in soil samples SB-19
and/or Soil-Dup-1. The arsenic detections are below the published average background
level for North Carolina soils and are likely naturally occurring. The detected hexavalent
chromium concentrations are likely naturally occurring based on the low-level and even
distribution of concentrations across the Site and lack of obvious on-Site sources based

on historical Site operations.

 Results of soil gas assessment activities indicate the presence of the VOCs benzene, 1,2-
dichloroethane, ethylbenzene, heptane, hexane, naphthalene, 1,2,4-trimethylbenzene,
1,3,5-trimethylbenzene, m&p-xylenes, and/or o-xylene in one or more samples at
concentrations that exceed the Residential and/or Non-Residential SGSLs.

 Cumulative risk calculator results using data for samples SG-13 and SG-14 indicate
carcinogenic and/or non-carcinogenic risk levels above acceptable risk levels under
residential and non-residential land use scenarios. Cumulative risk calculator results
using data for sample SG-12 did not indicate exceedances of acceptable risk levels under
a residential or non-residential land use scenario.

 Based on the results of soil gas sampling and risk calculations, there is a potential vapor
intrusion concern for the proposed mixed-use building in the eastern portion of the Site.

FLAG/QUALIFIER SUMMARY
*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
RL Reporting Limit is at the level of quantitation (LOQ)
DL Detection Limit is the lower limit of detection determined by the MDL study
MCL Maximum Contaminant Level
ND Not Detected
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
[Undefined]Ja
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits.
Reported value for this compound is likely to be biased on the low side.
L-04
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
the other is within limits. RPD outside of control limits. Reduced precision anticipated for any reported result for
this compound.
L-07A
Matrix spike recovery is outside of control limits. Analysis is in control based on laboratory fortified blank
recovery.Possibility of sample matrix effects that lead to low bias for reported result or non-homogeneous sample
aliquot cannot be eliminated.
MS-07
Matrix spike recovery outside of control limits. Possibility of sample matrix effects that lead to a high bias for
reported result or non-homogeneous sample aliquots cannot be eliminated.
MS-11
Duplicate RPD is outside of control limits. Outlier can be attributed to sample non-homogeneity encountered
during sample prep.
R-02
Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any
reported value for this compound.
R-05
Elevated reporting limit due to high concentration of non-target compounds.RL-13

this compound.
V-05
Continuing calibration verification (CCV) did not meet method specifications and was biased on the high side for
this compound.
V-06
Continuing calibration verification (CCV) 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.
V-20
Initial calibration verification (ICV) did not meet method specifications and was biased on the low side for this
compound. Reported result is estimated.
