2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Federal/State-Lead Groundwater
Monitoring Report (GMR) for the Save More #45 site. This report documents a groundwater
sampling event conducted at the site on January 20, 2015. The GMR is being performed based on a
January 16, 2015 Task Authorization (TA-1) by the Trust Fund Branch of the Underground Storage
Tank (UST) Section, Division of Waste Management, North Carolina Department of Environment
and Natural Resources (NCDENR). The work is being performed as part of the State Lead Contract
#N14004i between NCDENR and ATC.
Save More #45 is located at 1424 North Fayetteville Street in Asheboro, Randolph County, North
Carolina. The site consists of one single-story building that is used as a retail petroleum facility
and convenience store. Seven monitoring wells (MW-1 through MW-6 and VEW-1) are located at
the site. There are no water supply wells within 1,500 feet of the site and there is one surface water
body located 500 feet east of the site. Municipal water is available to the site and site vicinity.
On January 20, 2015, ATC personnel mobilized to the site to collect groundwater samples and
measure groundwater elevations. Groundwater samples were collected from monitoring wells MW-
2 through MW-6 and VEW-1. Monitoring well MW-1 contained 0.1 feet of free product. Free
product has not been detected at the site prior to the January 2015 sampling event. Groundwater
elevations measured at the site indicate groundwater flows south southwest across the site.
Laboratory analytical results of the January 2015 sampling event indicated petroleum hydrocarbon
compounds at concentrations exceeding North Carolina 2L Groundwater Standards (2L Standards)
in monitoring wells MW-3, MW-4, and VEW-1. In addition, groundwater concentrations indicate
MW-3 is impacted above Gross Contaminant Levels (GCLs).
Based on field observations and groundwater analytical results, ATC recommends:
• Placing a well boom in monitoring well MW-1 to abate the presence of free product;
• The installation of one on-site monitoring well in order to delineate groundwater
impacted above GCLs.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The Save More #45 site is located at 1424 North Fayetteville Street in Asheboro, Randolph County,
North Carolina. Currently, one single-story building operating as a retail petroleum facility and
convenience store exists on-site. The current UST system consists of one 14,000-gallon gasoline
UST, one 6,000-gallon gasoline UST, and one 4,000-gallon kerosene UST. The UST system was
installed in March and April 2003 and is still in use. The former UST system at the site consisted of
two 6,000-gallon gasoline USTs and one 8,000-gallon gasoline UST. The former UST system was
installed in May of 1972 and permanently removed in April 2003. The site is bounded by North
Fayetteville Street to the west, a lot with a vacant retail building to the north, a vacant lot zoned for
residential purposes to the east, and Rainbow Drive to the south. Surrounding properties are
characterized by residential and commercial use. A site topographic map is included as Figure 1
and a site map depicting pertinent site features is included as Figure 2. Current site photographs are
included in Appendix A.
3.2 Site Background
One November 16, 1995, gasoline product was discovered in the pump pit of one UST located
onsite. Between November 16 and 21, 1995, approximately 126 gallons of gasoline and
impacted water were removed from the UST pump pit. The UST pump was subsequently
replaced.
On January 19, 1997, an Initial Response, Abatement Measures, Site Check, and Initial Site
Characterization Report was submitted to the regional office and documented soil assessment
activities. Soil borings B-1 through B-3 were advanced around the UST system. Two of the
three boring indicated concentrations of Total Petroleum Hydrocarbons (TPH) above NCDENR
Action Level.
A Report of Soil Contamination and Phase I Limited Site Assessment (LSA) was submitted on
December 2, 1998. Three borings were advanced (MW-1, B-2, and B-3) for the purpose of soil

4
assessment. Soil sampled indicated exceedences of TPH above Action Level in all borings. The
original intent was to install a permanent monitoring well in boring MW-1; however,
groundwater was not observed in the boring so the well was not installed. A receptor survey
indicated there were no water supply wells within 1,500 feet of the site.
In April 2003, the UST system (product lines, dispensers, two 6,000-gallon gasoline USTs, and
one 8,000-gallon gasoline UST) were replaced due to site renovations. During UST excavation
and removal, soil samples were collected from beneath the dispensers, product lines, and USTs.
Soil analytical results indicated compounds exceeding Soil-to-Groundwater Maximum Soil
Contaminant Concentrations (MSCCs). No soil excavation was performed following UST
removal. Subsequent to removal, one 14,000-gallon gasoline UST, one 6,000-gallon gasoline
UST, one 4,000-gallon kerosene UST, dispensers and product lines were installed at the site. A UST
Closure Report was submitted on May 12, 2003.
A Phase I/II LSA was submitted to NCDENR on December 18, 2003. During LSA activities,
monitoring wells MW-1 through MW-6 and VEW-1 were installed and sampled. Based on
laboratory analytical results, groundwater concentrations exceeded GCLs at the site. A receptor
survey indicated there were no water supply wells within 1,500-feet of the site; however, an
intermittent stream was identified within 250 feet of the site.
A Comprehensive Site Assessment was submitted on June 16, 2004. During the CSA, nineteen soil
borings were advanced and sampled. Laboratory results indicated seven of the nineteen borings
were impacted above Soil-to-Groundwater MSCCs, but below Industrial/Commercial MSCCs.
A groundwater sampling event was performed in March 2009. Groundwater laboratory results
indicated impacts exceeding GCLs at the site. Free product was not detected during the sampling
event. In addition, the monitoring report indicated the nearest surface water body was located 500
feet east of the site. A Groundwater Monitoring Report was submitted on July 15, 2009.

3.3 Site and Regional Geology
The site is located in the Inner Piedmont Province in the Charlotte and Milton Belts. More
specifically, the site is underlain by the Uwharrie Formation; Felsic Metavolcanic Rock which is
characterized by light gray to greenish gray metamorphosed dacitic to rhyolitic flows and tuffs,
and is interbedded with mafic and intermediate metavolcanic rock, meta-argillite, and
metamudstone. Lithology recorded during historical activities indicates reddish orange silty clay
from the ground surface to approximately 10 feet below ground surface (bgs), orangish tan to
tannish gray silt from 10 feet to 12 feet bgs, and partially weathered rock from approximately 12
feet to 15 feet bgs. Competent rock was noted as shallow as 15.5 feet bgs.
3.4 Site and Regional Hydrogeology
The occurrence and movement of groundwater in the Piedmont is within two separate but
interconnected water-bearing zones. A shallow water-bearing zone occurs within the surficial
soils and a deeper zone occurs within the underlying bedrock. Groundwater in the shallow soil
zone occurs in the interstitial pore spaces between the grains comprising the surficial
soils. Groundwater in this zone is typically unconfined. Groundwater movement is generally
lateral from recharge areas to small streams that serve as localized discharge points. The
occurrence and movement of groundwater in the underlying water-bearing zone within the
crystalline bedrock is controlled by secondary joints, fractures and faults within the bedrock. On
a regional scale, the direction of groundwater flow is typically from uplands to major streams
and groundwater sinks.
Slug tests have not been performed at the site; however, based on groundwater elevation data and
recorded lithology, it appears the groundwater table is within the bedrock zone at the site. Based
on published sources, the average hydraulic conductivity for unfractured metamorphic and
igneous rocks is approximately 8.99 x 10-8 feet/day and the average hydraulic conductivity for
fractured metamorphic and igneous rocks is approximately 9 x 10-5 feet/day. Based on January
2015 groundwater elevation data, horizontal hydraulic gradient was calculated at 0.054 feet/feet
when using data from monitoring wells MW-4 and MW-5. Monitoring wells MW-1 and VEW-1
indicated a vertical hydraulic gradient of 0.013 feet/feet with a downward flow. Groundwater
flows south across the site.

4.0 GROUNDWATER CHARACTERIZATION
4.1 Groundwater Levels
Groundwater level measurements were collected from monitoring wells MW-1 through MW-6 and
VEW-1 on January 20, 2015. Monitoring well construction details and current and historical
groundwater elevation data are summarized in Table 1. Free product was observed in monitoring
well MW-1 at a thickness of 0.1 feet. Free product has not been detected at the site prior to the
January 2015 sampling event. GDepth to groundwater measurements ranged from 18.91 feet bgs in
MW-5 to 23.65 feet bgs in VEW-1. A groundwater elevation contour map generated using the
January 2015 groundwater elevation data is included as Figure 3. This figure indicates that the
direction of groundwater flow at the site is generally to the south southwest. Field notes from the
January 20, 2015 site visit are included in Appendix B.
4.2 Groundwater Quality
Historically at the site, monitoring wells MW-1, MW-3, and VEW-1 have contained the highest
petroleum hydrocarbon compound concentrations at the site. Maximum historical concentrations
for key petroleum constituents are 12,400 micrograms/liter (µg/L) for benzene (MW-1), 1,300
µg/L for toluene (MW-3), 1,430 µg/L for ethylbenzene (MW-1), 2,780 µg/L for total xylenes
(MW-1), and 226,000 µg/L for methyl tert-butyl ether (MTBE) (MW-1). It should be noted that
analytical results from the January 2015 monitoring event for MW-3 indicate the highest levels
detected at the site for benzene, toluene, ethylbenzene, and total xylenes.
On January 20, 2015, groundwater samples were collected from monitoring wells MW-2 through
MW-6 and VEW-1. A sample was not collected from monitoring well MW-1 due to the
presence of free product. Samples were collected in laboratory-approved containers, packed in
ice and delivered under chain-of-custody protocol to Contest Analytical Laboratory (Contest) in
East Longmeadow, Massachusetts for analyses. Groundwater samples were analyzed for volatile
organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 6200B.
The laboratory analytical results indicated the presence of petroleum hydrocarbon compounds at
concentrations above 2L Standards in monitoring wells MW-3, MW-4, and VEW-1.
Federal/State-Lead Groundwater Monitoring Report April 15, 2015
Save More #45 (Incident #15046) ATC Project No. NCDENR2002
7
Compounds detected above 2L Standards in include benzene, toluene, ethylbenzene, total
xylenes, MTBE, isopropyl ether, naphthalene, isopropylbenzene, n-propylbenzene,
tetrachloroethylene, and 1,2,4-trimethylbenzene. Tetrachloroethylene is not typically associated
with petroleum releases and is thought to originate from an off-site source. Benzene
concentrations exceeded GCLs in monitoring well MW-3. Current groundwater analytical data
are summarized in Table 2 and historical groundwater analytical data is summarized in Table 3.
Isoconcentration contour maps for benzene, MTBE, and naphthalene are included as Figures 4
through 6, respectively. Additional chemicals of concern are shown in Figure 7. The laboratory
analytical report and chain-of-custody forms are included in Appendix C.
As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of
the laboratory report was conducted. During the review, it was concluded that samples were
received by the laboratory in acceptable condition and properly preserved. The samples were
analyzed within the correct holding times, and the chain of custody was properly completed by
all parties. The laboratory QC report shows an internal blank was analyzed for each method that
was used for the original samples. The laboratory fortified blank (LFB) and laboratory control
sample (LCS) data results were also provided for each analytical method. Refer to the laboratory
reports in Appendix C for details regarding QA results for the laboratory samples and any noted
exceptions. ATC concludes that the laboratory results are usable and any exceptions do not
significantly impact the conclusions presented in this report.
5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed a GMR
documenting a January 20, 2015 monitoring event for the Save More #45 site at 1424 North
Fayetteville Street in Asheboro, Randolph County, North Carolina. Results from the monitoring
event indicate VOC impact in monitoring wells MW-3, MW-4, and VEW-1 above the 2L
Standards. Monitoring well MW-3 indicated impact above GCLs. In addition, free product was
detected in monitoring well MW-1 at a thickness of 0.1 feet. Field observations indicate
groundwater flows south across the site.

Based on field observations and groundwater analytical results, ATC recommends placing a well
boom in monitoring well MW-1 in order to abate the presence of free product. In addition, ATC
recommends the installation of one downgradient monitoring onsite to delineate the extent of
groundwater impacted above GCLs.
