Groundwater Monitoring Report September 2023

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. 8232 (Site), located at 24 South Raleigh Street, Angier, Harnett County, North
Carolina. Williams Family Heirs, LLC currently owns the Site, and Speedway operates the Site as a petroleum retail
facility and convenience store.
In April 2022, an Additional Assessment Report was submitted to the NCDEQ by Speedway’s former consultant, ATC
Associates of North Carolina, P.C. [(ATC), 2022]. The Additional Assessment Report recommended comprehensive
groundwater monitoring events be conducted to determine the stability of the impacted groundwater plume and
perform a survey of monitoring well MW-04. The NCDEQ requested the collection and submittal of groundwater
samples from all wells exceeding the Title 15 NCAC 2L.0202 Groundwater Standard (2L Standard) and survey of all
wells to determine the groundwater flow direction.

On June 27, 2023, six monitoring wells 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. Laboratory results indicate the presence of petroleum compounds in several monitoring wells at
concentrations that exceed the 2L Standard but not the Gross Contamination Level (GCL). Light non-aqueous phase
liquid (LNAPL) has not been detected in any of the wells gauged.
AECOM, on behalf of Speedway, recommends conducting one more semi-annual groundwater monitoring event to
confirm the concentration of petroleum constituents remains below the GCLs at all wells for at least four consecutive
monitoring events. During the February 2021, November 2022, and June 2023 groundwater monitoring events at
wells MW-05 and MW-06, petroleum constituents remained below the GCLs. If the petroleum constituents remain
below the GCLs during the next semi-annual groundwater monitoring event, AECOM will recommend re-classifying
the Site as low risk and request no further action (NFA) following a Notice of Residual Petroleum (NRP) filed on the
property.

2.3 Information about the Release
The following releases are associate with the current Incident #42211:
• On December 4, 2017, water was detected in the diesel underground storage tank (UST) No. 1. Sludge
and diesel fluid were removed, and the tank was placed out of service. The release was reported on
December 5, 2017 with the submittal of Form UST-61. According to the Underground Storage Tank
AECOM 2-2

Speedway 8232
Angier, NC
Groundwater Monitoring Report September 2023

Closure Report (ATC, 2021), the diesel UST No. 1 was closed in place on June 7, 2021. Incident
number 42211 was assigned to this release by the NCDEQ. This incident is still open.
• On September 18, 2018, Speedway submitted an NCDEQ Form UST-17A, which documented a failed
tank tightness test of the premium unleaded gasoline UST No. 4. On September 19, 2018, UST No. 4
was repaired, and the tank tightness tests were passed. Form UST-61 was submitted on May 10, 2019.
This incident was included in Incident No. 42211 and is still an open case.
• On May 7, 2019, a diesel spill occurred at satellite dispenser No. 12 due to a leaking hose/nozzle. On
May 10, 2019, Speedway submitted NCDEQ Form UST-61. The Site Check Report (ATC, 2019a)
summarizes Speedway’s emergency response and site check activities. ATC submitted the Limited Site
Assessment (LSA) to the NCDEQ on August 16, 2019. The NCDEQ tracked the diesel under UST No.
FA-7992, however, an incident number was not assigned.
The NCDEQ determined that the releases associated with the diesel UST No. 1 and the premium unleaded gasoline
UST No. 4 would be addressed together under Incident No. 42211. The NCDEQ also determined that the releases
associated with Incident No. 42211 are commingled with the release associated with Incident No. 8132, which
occurred in 1991 and was closed in 1992.

Speedway’s former consultant, ATC, submitted an LSA on December 23, 2019. Based on the results of the LSA, the
NCDEQ issued a Notice of Regulatory Requirement (NORR) on February 5, 2020 requesting a Phase II LSA to be
conducted. The LSA Phase II Report (ATC, 2020) was submitted to the NCDEQ on August 13, 2020. After reviewing
the LSA Phase II report, the NCDEQ issued a NORR on November 25, 2020 requesting that further assessment be
conducted, and a groundwater sampling report be submitted to further assess contamination and determine further
assessment or corrective action. A groundwater monitoring report was submitted to the NCDEQ on July 2, 2021.
Based on the results from the groundwater monitoring report, the NCDEQ requested one additional Type II
monitoring well to be installed. The field activities were conducted in May 2021. An Additional Assessment Report
was submitted to the NCDEQ on April 15, 2022. The NCDEQ acknowledged the receipt of the report in a letter dated
May 9, 2022. The NCDEQ requested the collection and submittal of groundwater samples from all wells exceeding
the 2L Standard and survey of all wells to determine the groundwater flow direction.

3.4.1 Zoning
The Site and adjoining properties are currently zoned Residential and business (Harnett County GIS Viewer, 2023).
The Site is located at 24 South Raleigh Street, Angier, North Carolina, and is accessed from West Depot Street,
located North of the Site, and South Raleigh Street, located East of the Site. Various commercial and residential
properties surround the Site.
3.4.2 Site Geology and Hydrogeology
Site geology was evaluated based on historical and current investigations completed by previous consultants and
AECOM. The Site is located within the Inner Coastal Plain Physiographic Region of North Carolina and is underlain
by the Cretaceous Middendorf Formation. The Site is generally underlain by sand, sandstone and mudstone, pale
gray to gray in color with orange casts, clay balls and iron-cemented concretions. Crossbedding is common and the
beds are laterally discontinuous. Previous investigations show the soil has consisted of mainly dark brown to tan
sandy silts and silty sands.
Groundwater is encountered on average at approximately 2.59 feet below ground surface (bgs). Based on the results
of the June 27, 2023, gauging event, groundwater flow is to the south, which is generally consistent with historical
groundwater flow. Well construction and historical groundwater elevations are summarized on Table 3, and a
groundwater elevation map (Figure 3) was constructed based on the June 27, 2023, gauging results.
The hydraulic gradient, as measured from monitoring well MW-02 to MW-05, is 0.005 feet-per-foot [(284.62-
284.05)/125].

4 Receptor Information
4.1 Water Supply Wells
Speedway’s previous consultant, ATC, conducted a receptor survey as part of the LSA to identify the presence of
water supply wells within a 1,500-foot radius of the Site. The receptor survey is cited within the LSA report submitted
in December 2019.
4.1.1 Private Water Supply Wells
Suspected well structures were identified according to the LSA report submitted in December 2019. Water supply well
forms were sent to property owners at the suspect locations. In addition, water supply well forms were sent to all
properties within 500 feet of the Site. Based on the completed/returned water supply well surveys, no water supply
wells were identified in the vicinity of the Site.
4.1.2 Public Water Systems
Harnett County Department of Public Utilities (HCDPU) is the primary water utility for the area. The public water
sources are the Cape Fear River, located approximately eight miles southwest of the Site.
Based on currently available information, many properties surrounding the Site receive their municipal water supplies
through buried piping beneath the streets and highway easements.
4.2 Surface Water
No surface water was observed on the Site. The previous consultant identified a small, intermittent stream
approximately 275 feet west of the Site. A stormwater drainage ditch is located approximately 270 feet west of the
Site and drains into the Black River approximately 1,500 feet northeast of the Site. A small, unnamed creek – a
tributary of the Black River – was identified about 1,000 feet southwest of the Site.
4.3 Wellhead Protection Areas
According to the NCDEQ Well Head Protection website (NCDEQ, 2023), last updated in May 2023, there are no
approved wellhead protection plans located in Harnett County.

5 Groundwater Investigation
During the current monitoring period, activities included groundwater gauging and sampling six monitoring wells.
5.1 Groundwater Gauging
On June 27, 2023, monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05, and MW-06 were gauged for depth to
water and depth to LNAPL, if present. LNAPL was not observed at the Site. Depths to groundwater ranged from 1.32
to 3.62 feet bgs at monitoring wells MW-05 and MW-02, respectively. Depth to water and calculated groundwater
elevations for the current and historic gauging events are included in 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 June 27, 2023, six monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05, and MW-06 were gauged, purged,
and sampled by AECOM field staff. The groundwater samples were analyzed for VOCs via EPA Method 6200B.
Laboratory results indicate the presence of petroleum compounds in several monitoring wells at concentrations that
exceed the 2L Standard but not the GCLs. Contaminants detected above the 2L Standard include benzene and
naphthalene (MW-01, MW-03, MW-04, MW-05 and MW-06); ethylbenzene and isopropylbenzene (MW-01 and MW-
06); total xylenes and 1,2,4-trimethylbenzene (MW-01); methyl tert-butyl ether (MW-03 and MW-06); and n-
propylbenzene (MW-01, MW-03, and MW-06).

Recent and historical analytical results are summarized in Table 4. A contaminants of concern concentration map is
shown in Figure 4. The laboratory analytical report is included as Appendix A.
5.4 Monitoring Well Survey
On June 27, 2023, six monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05 and MW-06 were surveyed using a
Duncan Parnell VRS-GPS unit. The VRS-GPS unit provided elevations with respect to the NAD83 (2011) datum. The
top of casing elevations stayed the same for all monitoring wells. Current and historical top of casing elevations are
summarized in Table 3.

7 Discussion
Analysis of the groundwater samples collected on June 27, 2023, indicate the presence of petroleum compounds in
several monitoring wells at concentrations that exceed the 2L Standard but not the GCL. Based on the results of the
groundwater monitoring event:
 Contaminants detected above the 2L Standard include benzene and naphthalene (MW-01, MW-03, MW-04,
MW-05 and MW-06); ethylbenzene and isopropylbenzene (MW-01 and MW-06); total xylenes and 1,2,4-
trimethylbenzene (MW-01); methyl tert-butyl ether (MW-03 and MW-06); and n-propylbenzene (MW-01, MW-
03, and MW-06).
 LNAPL was not detected in the on-site monitoring wells gauged.
 Water level measurements indicate that groundwater flow direction corresponded with historical flow direction,
which has been generally towards the south.
AECOM, on behalf of Speedway, recommends conducting one more semi-annual groundwater monitoring event to
confirm the concentration of petroleum constituents remains below the GCLs at all wells for at least four consecutive
monitoring events. During the February 2021, November 2022, and June 2023 groundwater monitoring events at
wells MW-05 and MW-06, petroleum constituents remained below the GCLs. If the petroleum constituents remain
below the GCLs during the next semi-annual groundwater monitoring event, AECOM will recommend re-classifying
the Site as low risk and request no further action (NFA) following a Notice of Residual Petroleum (NRP) filed on the
property.

SPEEDWAY 8232/60689740
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.
