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. 7976 (Site), located at 1006 Charlotte Highway, Troutman, Iredell County, North
Carolina. The site is currently owned by Speedway, LLC. and is operated by Pilot as a petroleum retail facility and
convenience store. Currently, the site is operational with convenience store with gasoline and diesel sales. This
report includes the groundwater sampling conducted in September 2022.
A release from the diesel fuel underground storage tank (UST) system was reported by WILCOHESS personnel on
December 31, 2001. A Comprehensive Site Assessment (CSA) was completed for the site in 2003 and a Corrective
Action Plan (CAP) proposing risk reduction through abandonment of nearby water-supply wells, LNAPL removal
through mobile multi-phase extraction (MMPE), and bioventing of soils was approved by the North Carolina
Department of Environment and Natural Resources (now the North Carolina Department of Environmental Quality) on
January 7, 2005. In a letter dated October 21, 2008, further assessment and cleanup was suspended due to Session
Law 2004-124.
The site’s risk classification was reduced from “high” to “intermediate” in July of 2009 after it was confirmed that the
two water-supply wells located within 1,000 feet of (and greater than 250 ft from) the source area of the release were
no longer used for drinking. The North Carolina Department of Environmental Quality (NCDEQ) issued a Notice of
Regulatory Requirements (NORR) dated April 4, 2011. A detailed site history was submitted in the CSA report dated
January 17, 2003.
On January 26, 2022, Mid-Atlantic (former Speedway environmental consultant) personnel gravity-injected surfactant
prior to the 96-hour Mobile Multi-Phase Extraction (MMPE) event. On February 7, 2022, through February 11, 2022,
light non-aqueous phase liquid (LNAPL) recovery activities via a MMPE event took place. Additionally, on March 8,
2022, a groundwater monitoring event on select site monitoring wells was completed.
LNAPL recovery should continue to be conducted at the site until LNAPL is no longer present and contaminant
concentrations are below the GCLs. Semi-annual groundwater monitoring should continue at the site, and a
feasibility study for LNAPL recovery should be conducted for this site.

former USTs maintained at the Site is provided below and summarized in Table 2.
According to the Iredell County, North Carolina Geographic Information System (GIS) mapping service, the current
property owner of the subject site is listed as Speedway 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
On December 31, 2001, an accidental release during maintenance activities on one of the diesel USTs, was reported
and was issued incident No. 24101.
3.4 Site Characteristics
The location of the Site is shown on a portion of the United States Geological Survey Shepherds, NC (2022) digital
raster graphic file (Figure 1). The layout of the Site is found on Figure 2. The Site is currently operational. The Site is
occupied by a Pilot Convenience store with Pilot gasoline and diesel operations. The site is located at 1006 Charlotte
Highway, Troutman, North Carolina and is accessed from Charlotte Highway, located east of the site. Various
commercial properties surround the Site.
3.4.1 Zoning/Receptor Information
The Site and adjoining properties are currently zoned Residential Agricultural (RA), General Business (GB), Highway
Business (HB) (Iredell County GIS Viewer).
Receptor information for the site was documented in Mid Atlantic’s July 29, 2002 Phase II Limited Site Assessment
Report. No water supply wells were identified within a 250-foot radius of the site, three water supply wells were
identified within 250 and1,500-foot radius of the site (none are currently used for drinking water). Public water is
available to the subject site and to portions of the surrounding properties. The closest surface water body is an
unnamed tributary located about 700 feet south of the subject site, which drains to Kerr Branch and Weathers Creek.
A receptor survey update was not completed for this phase of work. For additional details, please refer to the LSA
report.
3.4.2 Site Geology and Hydrogeology
Site geology was evaluated based on historic Mid-Atlantic’s and current investigations. The site is located within
Fine-grained biotite gneiss,Massive to strongly foliated, minor layers of amphibolite and muscovite schist
of the Charlotte and Milton Belt. The site appears to be located in a predominantly metamorphic rock formation
AECOM 3-2
Speedway 7976
Troutman, NCGroundwater Monitoring Report November 2022
described as “Fine-grained biotite gneiss”. In general, the soils encountered at the Site consist of reddish,
reddish brown, tan and gray, clays, micaceous sand, clayey silts, and silty and generally getting coarser grained with
depth.
Based on the results of the September 2022 gauging event, groundwater flow is to the south, which is generally
consistent with historical groundwater flow. Historical groundwater elevations are summarized on Table 4, and a
groundwater flow map (Figure 3) was constructed based on the September 2022 gauging results.
The hydraulic gradient, as measured from monitoring well MW-8 to MW-16, is 0.028 ft/ft [(80.98-71.66)/328.53].

No surface water was observed on the Site. The closest surface water body is an unnamed tributary located about
700 feet south of the subject site, which drains to Kerr Branch and Weathers Creek. Wellhead Protection Areas
According to the NCDEQ Well Head Protection website, last updated in 2022, there are no approved wellhead
protection plans located in southern Iredell County.
AECOM 5-2
Speedway 7976
Troutman, NCGroundwater Monitoring Report November 2022
5 Groundwater Investigation
During the current monitoring period, activities included groundwater gauging and sampling.
5.1 Groundwater Gauging
Monitoring wells MW-1, MW-2R, MW-3 through MW-10, MW-10D, and MW-11 through MW-26 were gauged for depth
to water and depth to LNAPL (if present). Depths to groundwater ranged from 20.91 ft bgs (MW-17) to 26.20 ft bgs
(MW-16) in wells where LNAPL was not encountered. In wells where LNAPL was encountered the corrected depth to
groundwater ranged from 21.78 ft bgs (MW-3) to 22.51 ft bgs (MW-20).
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 disposable bailer. Depth to water and calculated groundwater elevations for the current and historic
gauging events are included on Table 4.
5.3 Groundwater Analytical Results
During this reporting period, select monitoring wells (MW-1, MW-6, MW-11, MW-13 and MW-25) were sampled on
September 20, 2022, and analyzed for analysis volatile organic compounds (VOCs) via EPA Method SM 6200B to
evaluate the effectiveness of the January 2022 surfactant injection and MMPE event.
Once the wells had been properly purged, natural attenuation parameter readings were collected using a YSI meter
and 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 (Pace), a North Carolina-certified laboratory.
Groundwater sampling results indicated petroleum hydrocarbon continued to impact the Site monitoring wells during
this reporting period.
- Benzene concentrations were not observed above the Gross Contamination Levels (GCL) in sampled site
monitoring wells. No other compounds exceeded GCLs.
Analytical results are summarized in Table 5. A dissolved benzene Iso-concentration map showing the results from
the September 2022 sampling event is included as Figure 4. Laboratory analytical reports are included in Appendix
A.
AECOM 6-3
Speedway 7976
Troutman, NCGroundwater Monitoring Report November 2022
6 LNAPL Investigation
LNAPL has historically been observed in monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7 and MW-
20. During the September gauging event only monitoring wells MW-3 and MW-20 had measurable LNAPL at 0.04 ft
and 0.14 ft, respectivly. This section discusses LNAPL gauging.
6.1 LNAPL Gauging
Historical gauging information is summarized in Table 4. During the current monitoring period, apparent LNAPL
thickness was gauged on September 20, 2022.
A LNAPL Delineation Map detailing the on site apparent LNAPL plume is included as Figure 5.
Graphs detailing LNAPL thickness over time are included as Appendix B. Based on these graphs, LNAPL
thicknesses for MW-3 and MW-20 are significantly lower when compared to their historical highs. Monitoring well
MW-3 had a high of 4.48 ft on June 18, 2003, and monitoring well MW-20 had a high of 2.37 ft on November 1, 2007.
The apparent LNAPL thickness within monitoring wells MW-3 and MW-20 increased when compared to the March 8,
2022 gauging event.
AECOM 8-1
Speedway 7976
Troutman, NCGroundwater Monitoring Report November 2022
7 Discussion
Analysis of the groundwater samples collected on September 20, 2022, indicated benzene and other contaminates of
concern continue to impact the Site in monitoring wells MW-1, MW-6, MW-11, MW-13 and MW-25.
Based on the results of the groundwater monitoring report:
 LNAPL was measured in monitoring wells MW-3 and MW-20 at apparent thicknesses of 0.04 ft and 0.14 ft,
respectively.
 Groundwater sampled from select site monitoring wells did not exhibit petroleum compounds at concentrations
exceeding benzene GCL.
 Water level measurements collected from the site indicated that groundwater flow direction corresponded with
historical flow direction which has been generally towards the south.
AECOM, on behalf of Speedway, recommends the following additional actions:
 LNAPL recovery should continue to be conducted by using absorbent socks in wells that have measurable
LNAPL thickness at the site until LNAPL is no longer present and contaminant concentrations are below the
GCLs. Semi-annual groundwater monitoring should continue at the site, and a feasibility study for LNAPL
recovery should be conducted for this site.

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.
