Executive Summary
As required by the North Carolina Department of Environmental Quality (NCDEQ), AECOM Technical Services of
North Carolina, Inc. (AECOM) on behalf of Speedway, LLC (Speedway) has prepared this Groundwater Monitoring
Report for Speedway Store No. 6953 (Site), located at 3030 North Main Street, High Point, Guilford County, North
Carolina (NC). The Speedway No. 6953 / WILCOHESS #154 facility (formerly Spanky’s One Stop) was moved to
3010 North Main Street, approximately 150 feet to the southeast. As part of the Site closure activities, the
underground storage tanks (USTs), product lines, dispensers, and canopy were removed in May through September
2013. Speedway is the responsibility party for the environmental release from Incident No. 44219. On November 9,
2019, the Site was sold by Williams Properties II LLC to MacDonald Ventures, LLC. Currently, MacDonald Auto Sales
operates an automotive dealership onsite. The Site is operational with an office building, former car wash, shed, and
used car lot. This report includes the groundwater sampling conducted in November 2022.
In July 2013, petroleum-impacted soil was identified during the removal of the UST system, prompting a release
report to county and state regulatory agencies. An incident number was assigned to the Site (Incident No. 44219).
No historical releases or compliance issues are known prior to this release. Five steel USTs were removed from the
Site in August 2013 – four 8,000-gallon gasoline USTs from one basin and one 8,000-gallon diesel UST from another
basin. Each of the five USTs were 8 feet in diameter and 24 feet in length. A subsequent soil investigation dated
August 2013, Limited site Assessment (LSA) dated April 2015 and two Comprehensive Site Assessments (CSAs)
dated August 2014 and April 2015, respectively were conducted at the Site to confirm the extent of contamination.
On May 14, 2015, the NCDEQ issued a Notice of Regulatory Requirement (NORR) for a Corrective Action Plan
(CAP). In addition, the Guilford County Department of Public Health and Environmental Risk Assessment (HERA)
requested a CAP be prepared to evaluate strategies to reduce the petroleum constituent concentrations to below the
Gross Contaminant Levels (GCLs) for groundwater. Speedway’s previous consultant, Simon & Associates of North
Carolina, Inc. (Simon), prepared the CAP and submitted it to the HERA and NCDEQ on July 8, 2015. On August 10,
2015, NCDEQ issued a NORR approving the CAP that recommended quarterly monitored natural attenuation (MNA)
activities be performed at the Site. These activities included monitoring and sampling monitoring wells at the Site to
determine if the dissolved phase petroleum constituent concentrations will naturally attenuate over time. A mobile
multi-phase extraction (MMPE) event was completed in July 2017 to assist in the reduction of groundwater
contaminant concentrations in monitoring wells MW-1 and MW-3. The initial MNA quarterly report was submitted on
November 30, 2015.

On November 14, 2022, four monitoring wells (MW-1, MW-2, MW-3, and MW-4) were gauged, purged, and sampled
by AECOM field staff. The groundwater samples were analyzed for Volatile Organic Compounds (VOCs) via
Environmental Protection Agency (EPA) Method 6200B. All reported contaminant concentrations were below the
GCL except for benzene in monitoring well MW-01. LNAPL was not detected in any of the wells gauged onsite.

In accordance with the CAP, AECOM, on behalf of Speedway, recommends the evaluation of more aggressive
treatment options to enhance the MNA remedy.

3 Site History and Characterization
The following sections provide information on the USTs operated at the Site and follows the general outline
established in Guidelines for Assessment and Corrective Action for UST Releases (NCDEQ, 2021a) and Guidelines
for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases (NCDEQ, 2021b) using the
Comprehensive Tables for Corrective Action Guidelines Tables (NCDEQ, 2022).
3.1 Underground Storage Tank Systems
Five steel USTs were removed from the Site in August 2013 – four 8,000-gallon gasoline USTs from one basin and
one 8,000-gallon diesel UST from another basin. The Site is currently in use as a used automotive dealership. UST
owner/operator and other responsible party information and UST system and other release information are included
in Tables 1 and 2, respectively.
According to the Guilford County, North Carolina Geographic Information System (GIS) mapping service, the current
property owner of the subject site is listed as MacDonald Ventures, LLC while Speedway remains the responsible
party of the USTs.
3.2 Aboveground Storage Tank Systems
No aboveground storage tank systems (ASTs) are currently present on site. Based on available information, no ASTs
have historically been present at the Site.
3.3 Historical Releases
No historical releases or compliance issues are known prior to the incident. The Site was issued incident No. 44219.

One incident (Incident No. 45350) was reported in December 2019 to an active Speedway gas station southeast of
the Site. The incident was closed in March 2020.
3.4 Site Characteristics
The location of the Site is shown on a portion of the United States Geological Survey High Point West / Kernersville,
NC (2022) digital raster graphic file (Figure 1). The layout of the Site Plan is found on Figure 2. The site is located at
3030 North Main Street, High Point, NC and is accessed from North Main Street, located west-southwest of the Site,
and Northside Court, located east-northeast of the Site. The Site currently operates as a used automotive dealership,
MacDonald Auto Sales. The Site is operational with an office building, former car wash, shed, and used car lot.
Various commercial and residential properties surround the Site.
3.4.1 Zoning/Receptor Information
The Site and adjoining properties are currently zoned Residential and business (Guilford County GIS Viewer).
In January 2015, a receptor survey was completed as part of a LSA to identify the presence of water supply wells
within a 1,500-foot radius from the Site. Within the LSA, the receptor survey is cited in the CSA report dated April
2015. All residents of the City of High Point are required by law to be serviced by municipal water and are prohibited
from using any pre-existing domestic water supply well.
3.4.2 Site Geology and Hydrogeology
Site geology was evaluated based on historic and current investigations completed by previous consultants and
AECOM. The Site is located in the Piedmont Physiographic Province of North Carolina. The Site is underlain by
crystalline, Paleozoic-age metamorphic rock. The shallow subsurface contains residual soil derived from in-situ
weathering of bedrock, and the soil varies in thickness from non-existent at bedrock outcrops to depths of
3-2

Speedway 6953 High Point, NC
Groundwater Monitoring Report February 2023

approximately 100 feet below ground surface (bgs) in areas of weathered bedrock. Soils underlying the site range
from structureless soils (residuum) to soils with light relict rock features (saprolite), to partially weathered rock (found
as a zone immediately above the parent bedrock). Based on past investigations by the previous consultant, soils at
the site consist mainly of brown, red and orange fine sandy and clayey silt.
Groundwater is encountered at approximately 28.38 feet bgs. Based on the results of the November 2022 gauging
event, groundwater flow is to the west/northwest, which is generally consistent with historical groundwater flow.
Historical groundwater elevations are summarized on Table 3, and a groundwater elevation map (Figure 3) was
constructed based on the November 2022 gauging results.
The hydraulic gradient, as measured from monitoring well MW-03 to MW-04, is 0.038 ft/ft [(968.54 - 964.71)/102.00].

4 Receptor Information
4.1 Water Supply Wells
A previous consultant, Simon & Associates of North Carolina, Inc. (Simon), conducted a receptor survey as part of an
LSA to identify the presence of water supply wells within a 1,500-foot radius from the Site. Within the LSA, the
receptor survey is cited in the CSA report dated April 2015.
4.1.1 Private Water Supply Wells
All residents of the City of High Point are required by law to be serviced by municipal water and are prohibited from
using any pre-existing domestic water supply well according to a CSA report dated April 2015. All streets within 1,500
feet of the site were field verified during the receptor survey as being serviced with public water utilities.
4.1.2 Public Water Systems
The Site obtains water from the City of High Point, which gets its water supply from High Point Lake (also known as
Oak Hollow Lake), approximately 1.5 miles east and topographically downgradient from the Site (High Point, 2021).
Based on currently available information, the majority of properties surrounding the site receive their municipal water
supplies through buried piping that runs beneath the streets and highway easements.
4.2 Surface Water
No surface water was observed on the Site. No surface water bodies have been identified within 500 feet of the Site.
The closest surface water bodies to the Site are Oak Hollow Lake – approximately 1.5 miles east of the Site – and
several small tributaries to Rich Fork Creek, approximately 0.25 to 0.5 miles to the west of the Site.
4.3 Wellhead Protection Areas
According to the NCDEQ Well Head Protection website, last updated in December 2022, there are no approved
wellhead protection plans located in Guilford County.

5 Groundwater Investigation
During the current monitoring period, activities included groundwater gauging and sampling. Monitor well
construction detail information is presented in Table 3.
5.1 Groundwater Gauging
On November 14, 2022, monitoring wells MW-1, MW-2, MW-3 and MW-4 were gauged for depth to water and depth
to light non-aqueous phase liquid (LNAPL), if present. LNAPL was not observed at the Site. Depths to groundwater
ranged from 26.80 to 31.05 feet bgs at monitoring wells MW-3 and MW-4, respectively. Depth to water and
calculated groundwater elevations for the current and historic gauging events are included on Table 3.
5.2 Groundwater Sampling
Prior to the collection of a groundwater sample for laboratory analysis, the depth to liquid or LNAPL was measured
using an electronic oil-water interface probe. If no LNAPL was present, the well was purged of at least three well
volumes using a dedicated disposable polyethylene bailer attached to nylon rope. Once the wells had been properly
purged, groundwater samples were collected from each location using dedicated disposable polyethylene bailers
attached to nylon rope. To collect a sample, the bailer was slowly lowered to a depth just beneath the water surface
in the well. The bailer was then recovered, and the contents carefully decanted into laboratory-supplied sample
containers, properly preserved, and delivered to Pace Analytical Services, LLC (Pace), a North Carolina-certified
laboratory.
5.3 Groundwater Analytical Results
On November 14, 2022, four monitoring wells MW-1, MW-2, MW-3, and MW-4 were gauged, purged, and sampled by
AECOM field staff. The groundwater samples were analyzed for Volatile Organic Compounds (VOCs) via
Environmental Protection Agency (EPA) Method 6200B. All reported contaminant concentrations were below the
GCL except for benzene in one monitoring well. Benzene was reported at a concentration of 17,800 micrograms per
liter (µg/L) in monitoring well MW-1. Benzene was initially detected at a concentration above the respective GCL of
5,000 µg/L in January 2014 (24,400 µg/L) and has shown a trend of decrease with the lowest concentration recorded
in March 2021 (11,400 µg/L). Benzene concentrations have increased slightly since March 2021. LNAPL was not
detected in any of the wells gauged onsite. Analytical results are summarized in Table 4. A contaminant of concern
concentration map is shown on Figure 4. Laboratory analytical reports are included in Appendix A.

Groundwater Monitoring Report February 2023

7 Discussion
Based on analysis of the groundwater samples collected on November 14, 2022, benzene was reported at a
concentration of 17,800 µg/L in monitoring well MW-1. Benzene was initially detected at a concentration
above the respective GCL of 5,000 µg/L in January 2014 (24,400 µg/L) and has shown a decreasing trend
with the lowest concentration recorded in March 2021 (11,400 µg/L). Benzene concentrations have increased
slightly since March 2021. LNAPL was not detected in any of the wells gauged onsite. Water level
measurements collected from the site indicated that groundwater flow direction corresponded with historical
flow direction which has been generally towards the west/northwest.
In the 2015 CAP, MNA was selected as the most cost-effective remedial option for the Site. It was
estimated that within four to six years the concentration of benzene should be reduced below the GCL with
this remedy. Since the first MNA report was submitted in November 2015, the concentration of benzene has
been reduced by approximately 30 percent. In accordance with the CAP, AECOM, on behalf of Speedway,
recommends evaluating the feasibility and cost of more aggressive treatment options to enhance the MNA
remedy.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
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.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
