EXECUTIVE SUMMARY
This executive summary section provides an abbreviated reporting of our Site observations and
findings. Refer to the main text and appendices for a complete reporting of our observations and
findings.
ESP Associates, Inc. (ESP) has completed a Subsequent Monitoring Report documenting
assessment activity performed at the Rusher’s Tire Service site (Incident No. 3136). The site is an
approximate 0.83-acre developed site (Tax Parcel No. 011420) located at 403 North Main Street in
Salisbury, Rowan County, North Carolina. This report was completed to summarize the findings of
assessment activities performed on June 1, 2023, in accordance with North Carolina Department of
Environmental Quality (NCDEQ), Task Authorization No. 1, approved on May 18, 2023.
The work was performed as part of the State Lead Contract #N70522-D between NCDEQ and ESP.
This report was prepared in general accordance with the 15A NCAC 2L .0115 regulations and the
NCDEQ Underground Storage Tank (UST) Section Guidelines for Assessment and Corrective Action
for UST Releases, January 2021, under the supervision of Christopher J. Ward, North Carolina
registered professional geologist (North Carolina License No. 1600).
Field activities performed by ESP on June 1, 2023, included:
• Gauging static water levels in existing site monitoring wells MW-8 and MW-9; and
• Collecting groundwater samples from monitoring wells MW-8 and MW-9.
Collected groundwater samples were analyzed for volatile organic compounds (VOCs) for
comparison to both North Carolina Groundwater Quality Standards 15A NCAC 2L .0202 (2L
Standards) and Gross Contaminant Levels (GCLs).
Based on results of the above sampling activities, ESP concludes the following:
• No water supply wells are located within 1,000 feet of the release;
• The static water levels at the site ranged from 13.85 to 13.89 ft bTOC;
• Based on historical data water level measurements, groundwater at the site is expected to
flow generally to the southeast;
• No free product was measured in MW-8 or MW-9;
• Benzene was detected above its GCL of 5,000 µg/L in MW-8 (6,020 µg/L);
• EDB was detected above its GCL of 50 µg/L in MW-8 (109 µg/L);
• Multiple VOCs were detected above their respective 2L standards in groundwater samples
collected from MW-8 and MW-9. These analytes included benzene, ethylbenzene,
isopropylbenzene, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-
trimethylbenzene, and xylenes;

• The field duplicate QC sample of MW-9 generally yielded comparable results as to the
MW-9 sample analyses;
• Benzene concentrations in MW-8 (6,020 µg/L) in June 2023 decreased from June 2021
(6,160 µg/L) and June 2020 (12,000 µg/L) events;
• EDB concentrations in MW-8 (109 µg/L) in June 2023 decreased from June 2021 (146
µg/L) and June 2020 (300 µg/L) events;
• Other detected VOCs in MW-8 increased in concentrations in June 2023 as compared to
the June 2021 event; however, VOCs decreased in concentrations in June 2023 as
compared to the June 2020 event; and
• Constituent concentrations detected in MW-9 in the June 2023 sampling event have
generally increased as compared to the June 2021 event while concentrations have mostly
decreased as compared to the June 2020 event.
Based on the above results, ESP offers the following recommendations:
• Continued annual sampling of existing monitoring wells MW-8 and MW-9;
• To address continued exceedances of standards in groundwater, it is recommended that
various bioremediation technologies be evaluated to facilitate the degradation of VOCs in
the subsurface.

INTRODUCTION
1.1 Site Setting
The Rusher’s Tire Service site is an approximate 0.83-acre developed site (Tax Parcel No. 5760-18-
41-6915) located at 403 North Main Street in Salisbury, Rowan County, North Carolina (see Figures
1 and 2). The site includes an occupied approximate 36,400-sqft Sharonview Federal Credit Union
building built in 2020 on the northern portion of the site and associated asphalt paved parking on the
southern portion of the site. The site is bounded to the north by North Main Street, to the east by a
commercial business, to the south by a retail strip center, and to the west by East Kerr Street.
1.2 Site Geology and Hydrogeology
A consideration of surface and subsurface drainage and geology are of interest since they provide
an indication of the direction that contamination, if present on-site or off-site, could be transported.
The site is located within the Charlotte Belt of the Piedmont Physiographic Province. The
Piedmont Physiographic Province generally consists of low to medium elevation, rounded hills,
and long rolling northeast to southwest trending ridges with incised creeks and river channels.
Rock at the site is described as metavolcanic rock. In-place chemical and physical weathering of
parent rocks typically form residual soils in the Piedmont region. Weathering is facilitated by the
presence of fractures, joints, and less resistant minerals in the rock. In areas not altered by erosion,
alluvial deposition or the activities of man, the typical residual soil profile consists of clay-rich
unconsolidated materials at the surface, transitioning to sandy silts and silty sands at depth.
Typically, the boundary between soil and rock is not sharply defined. This transitional zone is
termed “partially weathered rock” or saprolite. Information obtained from the Web Soil Survey
for Rowan County depicts soils on the site as Urban land (Uf).
In the Piedmont, groundwater generally occurs in pore spaces within soils and in the structural
features present in the underlying rock (i.e., joints, fractures, and faults). Recharge to the water
table is primarily by precipitation infiltrating the surficial soils and percolating downward under
the influence of gravity to the water table. Typically, the water table is not a level surface, but a
subdued reflection of the land surface. The depth to the water table is not consistent and is
dependent upon several factors that include the amount of rainfall, permeability of the soil, the
extent of fracturing in the underlying rock and the influences of groundwater pumping.
The direction and movement of groundwater through soil is generally dependent on soil type, the
presence of relict structures, and the textures of the underlying rock. Fractures, faults, folds, and
foliation planes affect the migration of groundwater in rock. No major geologic features (faults,
etc.) are present at or near the site. Groundwater typically flows in directions parallel to the ground
surface and under the influence of gravity, migrates to discharge points such as surface water
features, the toes of slopes or natural springs. Fluctuations in the depth of the water table can be

Rusher’s Tire Service (Incident #3136) August 8, 2023
2
expected depending on variations in precipitation, surface water run-off and other factors.
Normally, the highest levels of the water table occur in late winter and spring and the lowest levels
occur in the late summer and fall. Based on historical water level elevation data, groundwater at
the site is expected to flow generally to the southeast.
1.3 Surface Water
An unnamed tributary to Henderson Branch is located approximately 1,420 feet north of the source
area. This surface water body is considered upgradient and not at risk to constituent migration from
the site (see Figure 1).
1.4 Water Supply Wells
No water supply wells were identified within 1,000 feet of the source area. According to Terracon
Consultants, Inc (Terracon) “Initial Monitoring Report”, they conducted a windshield survey on June
24, 2021 to identify possible water supply wells and municipal water meters in the vicinity of the
site. No water supply wells were identified while municipal water was noted as being available to the
site and surrounding properties.

2.0 SITE HISTORY
The following description of historical site activities was obtained from a report titled “Initial
Monitoring Report - Rusher’s Tire Service (Incident #3163)” dated July 9, 2021, by Terracon.
Tabulated historic groundwater elevations, laboratory analytical results, and a well location map
are provided in Appendix A for reference.
The former on-site UST system comprised of three 3,000-gallon gasoline USTs that operated from
the early 1950s to the mid-to-late 1980s. Former waste oil and heating oil USTs were also
documented at the site. One prior release of petroleum product resulted in the installation of 2
monitoring wells and the replacement of the leaking UST in April of 1986. The gasoline USTs,
associated piping, dispenser islands and approximately 37 cubic yards of petroleum impacted soil
were removed from the site in March 2001. Five monitoring wells were installed between November
2001 and January 2002. The site was accepted into the NCDEQ State Lead Program in March of
2003.
In June 2003, S&ME performed a Free Product Evaluation/Recovery Report that included a free
product evaluation of all on-site monitoring wells. Approximately 0.45 feet of free product was
measured in well MW-4 and a trace amount of free product was measured in well MW-1.
Approximately 8 gallons of free product and contact water were removed from the wells via hand-
bailing. No measurable free product was observed in the monitoring wells following the hand-
bailing event.
Between June and September 2003, free product gauging events were conducted by Geological
Resources, Inc. (GRI) that indicated approximately 0.41 to 0.55 feet of free product in MW-4 and a
sheen to 0.02 feet of free product in MW-1. Benzene was detected in MW-2 and naphthalene was
detected in MW-3 above 2L standards in June 2003. A receptor survey was also completed in June
2003 that did not indicate any water supply wells within a 1,500-foot radius of the release.
Between October and December 2003, GRI conducted a mobile multi-phase extraction (MMPE)
event and groundwater sampling activities. During the MMPE event, approximately 727 gallons of
vapor phase hydrocarbons were removed along with 7,468 gallons of petroleum contact
groundwater. During the sampling event in December, free product was detected in monitoring well
MW-1 at a thickness of 0.04 feet. Multiple petroleum constituents were detected above their
respective 2L standards in monitoring wells MW-3, MW-4, and MW-6.
In March 2004, GRI advanced nine soil borings in the vicinity of the former UST basin, product
piping and dispenser island. Soil analytical results were below the regulatory action levels for both
TPH-GRO and TPH-DRO in two of the samples and no constituents were detected in the other soil
samples. It was determined that most of the affected soils had been removed during UST closure
activities except for a minor amount of soil impact within the former tank basin that was not accessible
due to proximity to local utilities.
Between April 2004 and October 2005, groundwater monitoring activities were conducted by GRI
and additional soil sampling was conducted in April 2004. Multiple petroleum constituents were

detected in wells MW-1, MW-4, and MW-6 above their respective GCLs and 2L standards. Soil
samples collected in the vicinity of the remaining affected soils indicated concentrations below soil-
to-water Maximum Soil Contaminant Concentrations (MSCCs) except for benzene, which was
detected below the Industrial/Commercial MSCC.
In October 2010, Progress Environmental Inc. (Progress) performed a Pre-Cap Monitoring event
that included the installation of a four-inch monitoring well (MW-1R) to replace MW-1 and the
sampling of the existing monitoring wells. Analytical results from wells MW-1R, MW-4 and MW-
6 indicated constituents above their respective GCLs and results from well MW-3 indicated
constituents above their respective 2L standards.
In September 2011, Progress oversaw the excavation of accessible impacted soil as well the
abandonment of wells MW-1R, MW-4 and MW-6. Approximately 1,076 tons of impacted soil was
removed from the vicinity of the former UST system. Confirmation samples indicated target
compounds above their respective Soil-to-Groundwater MSCCs and aliphatics, aromatics, and
benzene exceeding their Residential MSCCs. Prior to backfilling the excavation, Progress
implemented in-situ chemical remediation by placing approximately 1,300 pounds of PermeOx Plus
in the base of the excavation at the approximate depth of the saturated zone. In addition to the
excavation of impacted soils, Progress removed one 550-gallon waste oil UST near the eastern
corner of the former service garage/gasoline station. Approximately 401 gallons of residual liquids
were removed from the UST along with approximately 71.80 tons of petroleum-impacted soils.
Confirmation samples taken in the waste oil excavation indicated targeted compounds in excess of
the Soil-to-Groundwater MSCCs and further soil assessment was recommended.
In October 2011, Progress observed the installation of wells MW-1A, MW-4R, MW-6R, and MW-
7. In November, Progress returned and sampled the site monitoring wells. Benzene was detected in
groundwater samples from monitoring wells MW-1A, MW-4R and MW-6R above its GCL and
EDB and 1,2-dichloroethane were detected in MW-6R above their GCL. Additional target
compounds were detected in multiple wells exceeding their respective 2L standards. No constituents
were detected above their 2L standards in wells MW-5 and MW-7.
In February 2013, Progress conducted a groundwater sampling event that included sample collection
from all existing site monitoring wells. Benzene was detected above its GCL in wells MW-1A, MW-
4R, and MW-6R while EDB and 1,2-dichloroethane were detected in well MW-6R above their
GCLs. Petroleum constituents were detected above their respective 2L standards in all site wells
except for MW-5.
Between December 2014 and August 2018, S&ME performed groundwater monitoring events that
included sampling groundwater from all site wells and gauging for free product in well MW-1. O-
Sox were installed in wells MW-1A, MW-3, MW-4R, and MW-6R in July 2017 to facilitate
remediation and were removed in August 2018.
In February 2019, S&ME abandoned all seven of the site monitoring wells (MW-1A, MW-2, MW-
3, MW-4R, MW-5, MW-6R, and MW-7) due to the redevelopment of the property as the current
bank building.

In May 2019, Griffith Enterprises performed an Initial Site Assessment following the demolition of
the former service station in May 2019. The assessment included the removal of two pedestal style
hydraulic lifts, a concrete oil change pit and 30 feet of associated piping, and a bay drain and 80 feet
of associate piping. Soils samples taken indicated soil constituents at concentrations below the
Commercial/Industrial MSCCs. S&ME provided oversight for the removal of 490.96 tons of
petroleum impacted soils in the vicinity of the former gasoline UST basin following the removal of
the building and associated petroleum concerns.
In August 2019, a 550-gallon waste oil UST was uncovered during grading activities of the area of
the former service station. The UST along with approximately 60.2 tons of petroleum impacted soils
were excavated and removed from the site. Confirmation samples indicated no detected constituents
that exceeded the Residential MSCCs.
In May 2020, two new monitoring wells (MW-8 and MW-9) were installed near former MW-1A
and MW-6R locations. These wells were subsequently sampled in June 2020 with benzene, EDB,
and 1,2-dichloroethane detected above GCLs along with various other constituents above 2L
standards in MW-8 while benzene was detected above its GCL along with several other VOCs above
their 2L standards in MW-9.
In June 2020, groundwater from monitoring wells MW-8 and MW-9 were sampled with benzene,
EDB, and 1,2-dichloroethane detected above GCLs along with various other constituents above 2L
standards in MW-8 while benzene was detected above its GCL along with several other VOCs above
their 2L standards in MW-9.
In June 2021, Terracon samples MW-8 and MW-9. Benzene and EDB were detected above GCLs
along with various other constituents above 2L standards in MW-8 while no analytes were detected
above GCLs in MW-9. Several VOCs were detected above their 2L standards in MW-9.

3.0 FIELD ACTIVITIES
Field activities performed by ESP on June 1, 2023, included:
• Gauging static water levels in existing site monitoring wells MW-8 and MW-9; and
• Collecting groundwater samples from monitoring wells MW-8 and MW-9.
As provided in Appendix B, field logbook entries along with water level survey, groundwater
sampling, and field instrument calibration forms were completed in the field to document site
activities. Site photographs are also available in Appendix B. Details of field activities are
provided below.
3.1 Water Level Gauging
On June 1, 2023, prior to purging or collecting groundwater samples, depth to groundwater from
the top of casing (TOC) within each monitoring well was measured and recorded using a
decontaminated electronic water level meter. The water level measurements were collected by
first removing covers and plunger caps from all site monitoring wells and allowing water within
the wells to stabilize. The electronic water level meter probe was then lowered into the well and
the depth to water measured relative to the well’s TOC.
As noted on Table 1, static water level depths were measured at 13.89 feet below TOC (ft bTOC)
in MW-8 and 13.85 ft bTOC in MW-9. The static water elevations from these two monitoring
wells are depicted on Figure 3.
3.2 Free Product Evaluation
During the June 1, 2023, gauging event, free product was not encountered in either monitoring
wells MW-8 or MW-9.
3.3 Groundwater Sampling
On June 1, 2023, groundwater samples were collected from monitoring wells MW-8 and MW-9.
Groundwater samples were collected using dedicated and disposable polyvinyl chloride (PVC)
bailers (1.5” x 3’) attached to braided nylon rope. Prior to groundwater sample collection, each
well was purged using the bailer. During purging, water quality parameters including pH,
conductivity, temperature, and turbidity were measured using calibrated field water quality
instruments. Readings were taken at the start of purging and periodically until a minimum of three
well volumes were removed from the well and water quality parameters stabilized. Following
purging, a groundwater sample for laboratory analysis was collected from the well using the bailer.
The water quality parameters were recorded on groundwater sampling forms along with time,
water level depth, and cumulative volume of water purged (see groundwater sampling forms in
Appendix B).

Groundwater samples were collected following Guidelines for Sampling by the Underground
Storage Tank Section, Division of Waste Management, North Carolina Department of
Environmental Quality (NCDEQ, 2022). Groundwater samples were placed in laboratory-
prepared vials preserved with hydrochloric acid (HCl), labeled, and stored on ice in a cooler for
subsequent delivery under standard chain-of-custody (COC) procedures to Pace Analytical (Pace),
a North Carolina-certified laboratory, located in Huntersville, North Carolina, for analysis. The
groundwater samples were analyzed for VOCs by EPA Method 6200B including methyl-tert-butyl
ether (MTBE), ethylene dibromide (EDB), and isopropyl ether (IPE).
3.4 Field Quality Control Sampling and Analysis
One field duplicate sample (designated Field Duplicate) was prepared by collecting an additional
groundwater sample from MW-9. The sample was placed into laboratory-prepared vials preserved
with HCl immediately following collection. The field duplicate was analyzed for VOCs to affirm
the accuracy of analytical results.

4.0 GROUNDWATER ANALYTICAL RESULTS
Results of the laboratory analysis of groundwater samples MW-8 and MW-9 are tabulated in Table
2. As noted in Table 2, the groundwater analytical results are compared to both 2L standards and
GCLs (Gross Contaminant Levels). The Pace laboratory analytical report is provided in Appendix
C. A summary of the analytical results is as follows:
• Benzene was detected above its GCL of 5,000 µg/L in MW-8 (6,020 µg/L);
• EDB was detected above its GCL of 50 µg/L in MW-8 (109 µg/L);
• Multiple VOCs were detected above their respective 2L standards in groundwater samples
collected from MW-8 and MW-9. These analytes included benzene, ethylbenzene,
isopropylbenzene, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-
trimethylbenzene, and xylenes; and
• The field duplicate QC sample of MW-9 generally yielded comparable results as to the
MW-9 sample analyses.
Groundwater sampling results relative to each monitoring well location showing VOCs exceeding
their GCL and/or 2L standards are depicted on Figure 4. Figure 5 depicts the approximate lateral
extent of the dissolved benzene groundwater plume.
Notable trends of groundwater laboratory analytical results from the June 2023 sample event as
compared to previous June 2021 and June 2020 sampling events are summarized below:
• Benzene concentrations in MW-8 (6,020 µg/L) decreased in June 2023 as compared to the
June 2021 (6,160 µg/L) and June 2020 (12,000 µg/L) events;
• EDB concentrations in MW-8 (109 µg/L) decreased in June 2023 as compared to the June
2021 (146 µg/L) and June 2020 (300 µg/L) events;
• Other detected VOCs in MW-8 increased in concentrations in June 2023 as compared to
the June 2021 event; however, VOCs decreased in concentrations in June 2023 as
compared to the June 2020 event; and
• Constituent concentrations detected in MW-9 in the June 2023 sampling event have
generally increased as compared to the June 2021 event while concentrations have mostly
decreased as compared to the June 2020 event.

• Other detected VOCs in MW-8 increased in concentrations in June 2023 as compared to
the June 2021 event; however, VOCs decreased in concentrations in June 2023 as
compared to the June 2020 event; and
• Constituent concentrations detected in MW-9 in the June 2023 sampling event have
generally increased as compared to the June 2021 event while concentrations have mostly
decreased as compared to the June 2020 event.
Based on the above results, ESP offers the following recommendations:
• Continued annual sampling of existing monitoring wells MW-8 and MW-9;
• To address continued exceedances of standards in groundwater, it is recommended that
various bioremediation technologies be evaluated to facilitate the degradation of VOCs in
the subsurface.

LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
