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. The Site is currently owned by Williams Family Heirs, LLC and operates as an active Speedway gas station
and convenience store. This report includes the groundwater sampling conducted in November 2022.
In April 2022, an Additional Assessment Report was submitted to 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
performing a survey of the monitoring well MW-04. The NCDEQ acknowledged the receipt of the report in a letter
dated May 9, 2022. 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 all wells to determine the groundwater
flow direction.

On November 3, 2022, 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 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 onsite.
AECOM, on behalf of Speedway, recommends continued semi-annual groundwater monitoring events be conducted
in May and November 2023 to monitor natural attenuation of the contamination plume. The risk category of the Site
should remain “Intermediate” due to the presence of an intermediate stream approximately 275 feet west of the Site.

2.3 Information about the Release
Recently, there have been three releases associated with the Site:

– On December 4, 2017, water was detected in the Number (No.) 4 diesel UST. Sludge and diesel
fluid were removed, and the tank was placed out of service. The release was reported on December
AECOM 2-2

Speedway 8232 Angier, NC
Groundwater Monitoring Report February 2023

5, 2017 with submittal of the Form UST-61. The No. 4 diesel UST closed in place according to the
Underground Storage Tank Closure Report (ATC, 2021). Incident number 42211 was assigned to
this release by the NCDEQ.
– On September 18, 2018, Speedway submitted a NCDEQ Form UST-17A which documented a failed
tank tightness test of the No. 3 premium unleaded gasoline UST. On September 19, 2018, UST No.
3 was repaired and passed its tank tightness tests. Form UST-61 was submitted on May 10, 2019.
This incident was included in Incident No. 42211.
– 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 the emergency response and site check activities performed by Speedway. ATC
submitted the Limited Site Assessment (LSA) to the NCDEQ on August 16, 2019. The diesel spill
was tracked by NCDEQ under UST No. FA-7992, however, an incident number was not assigned.

NCDEQ determined that the releases associated with the No. 4 Diesel UST and the No. 3 Premium Unleaded
Gasoline UST would be addressed together under Incident No. 42211. NCDEQ also determined that the releases
associated with Incident No. 42211 are commingled with the release associated with Incident No. 8132 that occurred
in 1991 and was closed in 1992.

Speedway’s former consultant, ATC, submitted a Limited Site Assessment (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 NCDEQ on July 2, 2021. Based on the results from the groundwater monitoring report, 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. 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 all
wells to determine the groundwater flow direction.

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
The Site is currently in use as a Speedway gas station and convenience store and operates one 10,000-gallon and
one 6, 000-gallon regular unleaded gasoline UST, one 6,000-gallon premium unleaded UST and one 6,000-gallon
diesel UST. The current USTs were installed by the Trade Oil Company and are owned by Speedway.
UST owner/operator information and UST system information are included in Tables 1 and 2, respectively.
According to the Harnett County, North Carolina Geographic Information System (GIS) mapping service, the current
property owner of the Site is listed as Williams Family Heirs, LLC.
3.2 Aboveground Storage Tank Systems
No aboveground storage tank systems (ASTs) are currently present onsite. Based on available information, no ASTs
have historically been present at the Site.
3.3 Historical Releases
D.K. Taylor Oil Company, Inc. dba Dennings/Angier Exxon was responsible for Incident No. 8132 which was
discovered and reported on June 24, 1991 when gasoline-impacted soil was encountered beneath three (3) 6,000-
gallon gasoline USTs during removal activities. The USTs had been in service from 1973 and were removed in 1991
and 1993. The incident was closed on June 3,1992.

A former Gulf Station was located north of the Site. A release of unknown quantity from an unknown responsible
party was suspected. Records available on the NCDEQ Incident Map indicated that this incident was closed on
4/13/1999 following environmental investigation and corrective action activities performed by Chevron.
3.4 Site Characteristics
The location of the Site is shown on a portion of the United States Geological Survey Angier, NC (2022) digital raster
graphic file (Figure 1). The Site layout is found on Figure 2. The Site is currently operational and is occupied by a
Speedway petroleum retail facility and convenience store. A McDonald’s restaurant is also located onsite, to the
south of the convenience store. The Site is located at 24 South Raleigh Street, Angier, North Carolina and is
accessed from West Depot Street, located North of the Site, as well as from South Raleigh Street, located East of the
Site. 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 (Harnett County GIS Viewer). The
previous consultant, ATC Associates of North Carolina, Inc. (ATC), conducted a receptor survey to identify the
presence of water supply wells within a 1,500-foot radius from the Site. The receptor survey is documented in the
LSA (ATC, 2019b).
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 within the Inner Coastal Plain Physiographic Region of North Carolina and is underlain
AECOM 3-2

Speedway 8232 Angier, NC
Groundwater Monitoring Report February 2023

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 3.24 feet below ground surface (bgs). Based on the results
of the November 3, 2022, 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 November 3, 2022, gauging results.
The hydraulic gradient, as measured from monitoring well MW-02 to MW-05, is 0.005 ft/ft [(283.99-283.41)/128].

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 from 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 a 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, there were no
water supply wells 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 that runs 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, located approximately 1,500 feet northeast of the Site. A small, unnamed creek
– a tributary of the Black River – was identified approximately 1,000 feet southwest 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 Harnett County.
AECOM 5-1

Speedway 8232 Angier, NC
Groundwater Monitoring Report February 2023

5 Groundwater Investigation
During the current monitoring period, activities included groundwater gauging and sampling.
5.1 Groundwater Gauging
On November 3, 2022, monitoring wells MW-01, MW-02, MW-03, MW-04, MW-05 and MW-06 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 1.96 to 4.25 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 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 3, 2022, 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 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). Benzene and naphthalene were reported in monitoring wells MW-01, MW-03,
MW-04, MW-05 and MW-06. Ethylbenzene, methyl tert-butyl ether (MTBE) and isopropylbenzene was reported in
monitoring well MW-06. Total xylenes were reported in monitoring well MW-01. N-propylbenzene was reported in
monitoring wells MW-01, MW-03, MW-05 and MW-06.

Recent and historical analytical results are summarized in Table 4. A contaminants of concern concentration map is
shown on Figure 4. Laboratory analytical reports are included in Appendix A.

5.4 Monitoring Well Survey
On November 3, 2022, 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.

AECOM 7-1

Speedway 8232 Angier, NC
Groundwater Monitoring Report February 2023

7 Discussion
Analysis of the groundwater samples collected on November 3, 2022, 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:
− Constituents detected above the 2L Standard include benzene and naphthalene (MW-01, MW-03, MW-04,
MW-05 and MW-06); ethylbenzene, MTBE and isopropylbenzene (MW-06); total xylenes (MW-01); and n-
propylbenzene (MW-01, MW-03, MW-05 and MW-06).
− The concentrations of petroleum-related constituents have remained the same or decreased in all monitoring
wells except for monitoring well MW-05, the furthest downgradient well, which increased but remains well
below the GCL.
− LNAPL was not detected in any of the wells gauged onsite.
− Water level measurements collected from the Site indicate that groundwater flow direction corresponded with
historical flow direction, which has been generally towards the south.
AECOM, on behalf of Speedway, recommends continued semi-annual groundwater monitoring events be conducted
in May and November 2023 to monitor natural attenuation of the contamination plume. If constituents detected in
downgradient well MW-05 continue to increase, further delineation may be warranted downgradient of the Site to the
south. The risk classification for the Site should remain “Intermediate”.

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.
