As required by the North Carolina Department of Environment and Natural Resources in correspondence dated June 5, 2014,
AECOM North Carolina, Inc. (AECOM) prepared this Groundwater Monitoring Report for activities conducted at the 7-Eleven
Store No. 19847 (Site), located at 1610 S. Croatan Highway, Kill Devil Hills, North Carolina. The Site has been classified as
high risk due to the presence of nearby irrigation wells. The site is currently used as a 7-Eleven convenience store only; site
underground storage tanks (USTs) were removed in February 2013.
During the current investigation, the nine (MW-2R, MW-3R, MW-4 to MW-9, and DW-1) on- and off-site monitoring wells were
sampled. Groundwater samples were analyzed for volatile organic compounds (VOCs), Massachusetts Department of
Environmental Protection volatile petroleum hydrocarbons (VPH), and lead.
During sampling, eight VOC or VPH compounds were detected above their respective Title 15A North Carolina Administrative
Code 2L Groundwater Standards (2L Standards) in well MW-3 and/or MW-5: benzene, naphthalene, n-propylbenzene, 1,2,4-
trimethylbenzene, total xylenes, C5-C8 aliphatics, C9-C12 aliphatics, and C9-C10 aromatics. No other compounds exceeded
the 2L Standards during the August 5, 2014 sampling event. Groundwater concentrations of VOC and VPH compounds in
well MW-3 and MW-5 have decreased since the February 2014 sampling event, with most detected compounds in MW-3
decreasing by more than 50 percent. Since August 2012, prior to the removal of the Site USTs, concentrations of benzene,
naphthalene, toluene, 1,2,4-trimethylbenzene, total xylenes, and VPH compounds in MW-3 have decreased by more than an
order of magnitude.
The groundwater flow direction during the August 5, 2014 event was to the east, with a gradient of approximately 0.003 feet
per foot. This is consistent with historical observations of site groundwater flow.
AECOM attempted to contact two nearby property owners to sample their irrigation wells. The property owner at 1617
Wrightsville Avenue refused access. AECOM was unable to successfully contact the property owner at 1620 S. Memorial
Boulevard.
Based on the delineation of the plume, declining concentrations in MW-3 and MW-5, removal of the source of petroleum, and
the location of the nearest irrigation well 250 feet or more from the Site, AECOM, on behalf of 7-Eleven, requests closure.
Executive Summary
AECOM Environment 1-1

60263455 August 2014

As required by the North Carolina Department of Environment and Natural Resources (NCDENR) in correspondence dated
June 5, 2014 (also included in Appendix A), AECOM North Carolina, Inc. (AECOM) conducted a site-wide groundwater
monitoring event at the 7-Eleven Store No. 19847 (Site), located at 1610 S. Croatan Highway, Kill Devil Hills, North Carolina
(NC) (Figure 1-1 and Figure 1-2). A release was discovered during the in-place abandonment of underground storage tank
(UST) #2 on April 10, 2012 (AECOM, 2012a). An Initial Abatement Action Report (AECOM, 2012b), a Limited Site
Assessment (AECOM, 2012c), a UST closure report (AECOM, 2013a), and a Comprehensive Site Assessment (CSA)
(AECOM, 2013b) have been completed at the Site.

2.3 Information about the Release
After removing the UST #2 from service in May 2011 due to false leak detection warnings, 7-Eleven decided to abandon the
#2 gasoline UST tank in place. On April 10, 2012, strong petroleum odors were observed during the installation of two soil
borings, one of which was converted into a groundwater monitoring well. A suspected release was reported to NCDENR on
April 11, 2012. The release was confirmed with the receipt of analytical data, received April 18, 2012.
In February 2013, the three USTs were removed, including UST #2. Petroleum odors and soil staining were observed, and a
sheen of non-aqueous phase liquid was observed in the tank field following the removal of the USTs. Pinhole leaks were
observed in the walls of the fiberglass USTs.
2 Site Information
AECOM Environment 3-1

60263455 August 2014

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.
3.1 Underground Storage Tank Systems
UST owner operator and other responsible party information are provided in Table 3-1. A summary of current and former
USTs maintained at the Site is provided below and summarized in Table 3-2.
Three 10,000-gallon USTs were installed on-site in 1985. UST #2 was removed from service in May 2011 due to false leak
detection warnings, and was abandoned in place on April 10, 2012. A suspected release was reported to NCDENR on April
11, 2012. The three USTs were removed from the Site on February 6, 2013.
The USTs were single-walled fiberglass, with single-walled fiberglass piping and under dispenser containment. Since
installation, the USTs contained gasoline. At the time of removal, pinhole leaks were observed in the side of the USTs.
Based on observations made during the February 2013 tank removal, all three of the USTs may have contributed to the
release. AECOM has not conducted previous (pre-2012) investigations at this site. No reports of previous site investigations
(pre-2012) are known.
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 Release Information
No historical releases, prior to the release discovered during the 2012 UST abandonment activities, are known.
3.4 Site Characteristics and Land Use
The location of the Site is shown on a portion of the United States Geological Survey 7.5-minute topographic map of the Kill
Devil Hills, NC (1984) Quadrangle (Figure 1-1). The layout of the Site is found on Figure 1-2. The layout of the Site is found
on Figure 1-2. The Site is currently an active 7-Eleven convenience store located on the east side of South Croatan Highway
(US-158). The majority of the Site is occupied by the 7-Eleven building and paved parking area, with some grassy area along
the southern side of the Site. A drainage ditch is located along the west side of the Site.
The Site and surrounding properties are located within the Town of Kill Devil Hills and Dare County. Use of the Site and
surrounding properties is consistent with business and residential areas in an urban setting.
The Site and properties located within the Town of Kill Devil Hills generally receive municipal water from the Town of Kill Devil
Hills, which receives its water from Dare County Water Department. Properties located within Dare County receive municipal
water from Dare County or private wells.
No potable wells have been identified within 1,500 feet of the Site (AECOM, 2012b), and municipal water (from the Town of
Kill Devil Hills) is available to properties within 1,500 feet of the Site.
Two irrigation wells have been identified within 500 feet of the Site:
3 Site History and Characterization
AECOM Environment 3-2

60263455 August 2014

 1617 Wrightsville Avenue (approximately 250 feet southeast of the tank field) – The well was installed in 2000 to a depth
of 75 feet below ground surface (bgs) and is used for irrigation. Based on site reconnaissance, the well may be located in
a small structure adjacent to the residence; however, the well location could not be confirmed as the resident was not at
home during the site reconnaissance. The approximate location of the structure is shown on Figure 3-1.
 1620 South Memorial Boulevard (approximately 400 feet southeast of the tank field) – The well was installed in 2001 to a
depth of 50 feet bgs and is used for irrigation. No well-related structures were identified during the February 2013
reconnaissance; a presumed location of the well is shown on Figure 3-1.
Two additional irrigation wells were identified within 1,000 feet of the Site based on information provided by Mr. Charles Spry
(owner of 1617 Wrightsville Avenue) and confirmed by discussions with representatives of the property owners. One irrigation
well is present at Nags Head Hammocks, located at 1801 Croatan Highway and approximately 750 feet cross-gradient from
the Site, and one irrigation well is present at Wings, located at 1405 S. Croatan Highway and approximately 650 feet cross-
gradient of the Site.
The information on private wells is summarized on Table 3-3.
3.5 Site Geology and Hydrogeology
The Site is located within the Coastal Plain physiographic province. Based on observations made during the installation of the
six site monitoring wells, subsurface soils consist predominantly of brown to gray fine sand (Unified Soil Classification System
[USCS] symbol SP) to 20 feet bgs. A layer of poorly sorted sand (USCS symbol SW) was observed at deep well DW-1 from a
depth of 20-25 feet, below which brown-gray fine sand continued to a depth of 53 feet. A gray clay layer containing shell
material (USCS symbol CL) was encountered from 53-54 feet. Below the clay layer, the brown-gray fine sand continued until
the monitoring well boring was terminated at 70 feet bgs. Petroleum odors and elevated photo ionization detector readings
were noted during the installation of MW-5 and DW-1. No odor, staining, or other evidence of petroleum contamination was
observed during the installation of wells MW-2R and MW-6, located north and west of the tank field, respectively.
The Site topography is generally flat. Historically, groundwater has been encountered between roughly 1.5 feet bgs and 4.5
feet bgs. Aquifer testing was attempted in August 2013 during the CSA phase, but was not completed due to the quick
recharge of the Site monitoring wells. Based on Site lithology and literature values, the hydraulic conductivity of the surficial
aquifer was estimated to be approximately 0.0032 centimeters per second or 9 feet per day (AECOM, 2013b).
Assuming the shallow wells to be fully penetrating (aquifer thickness of 12 feet) and using aforementioned literature value for
hydraulic conductivity, the calculated transmissivity is 1.17 centimeters squared per second or 108 square feet per day.
Groundwater flow was determined to be eastward toward the Atlantic Ocean. The hydraulic gradient was approximately 0.003
feet per foot (ft/ft) in August 2014. Based on liquid level data, it appears that the gradient flattens out across the former tank
field, which is likely related to the presence of fill material.
3.6 Current Status of Remediation
To address the subsurface contamination, 102,617 gallons of petroleum-impacted water was removed from the tank field wells
and well MW-3 and 351.69 tons of petroleum-impacted soils were removed from the subsurface. These initial abatement
measures were conducted with approval from NCDENR during UST removal.
The following post-excavation activities have been conducted at the Site as part of the groundwater monitoring investigation:
 In October 2012, monitoring well MW-3 was over-drilled and replaced with a 4-inch diameter well.
 In July 2013, monitoring wells MW-2R and MW-6 were installed to replace monitoring wells MW-1 and MW-2, which were
destroyed during the UST removal.
 In July 2013, monitoring wells MW-5 and DW-1 were installed to further characterize site groundwater conditions.
 In May 2014, monitoring wells MW-7 to MW-9 were installed off-site.

AECOM Environment 4-1

60263455 August 2014
Site activities were conducted in accordance with the Region 4 United States Environmental Protection Agency (EPA)
Environmental Investigations Standard Operating Procedures and Quality Manual.
4.1 Groundwater Sampling
A groundwater sample was collected from each of the nine site groundwater monitoring wells (MW-2R to MW-9 and DW-1) on
August 5, 2014. Prior to sampling, each well was gauged using an oil/water interface probe. Figure 1-2 shows the monitoring
well locations. The elevation summary for the wells is provided in Table 4-1.
Dedicated disposable bailers were used to purge and sample monitoring wells MW-2R to MW-6. Due to the depth of
monitoring well DW-1, a monsoon pump was used to purge the well, and a dedicated disposable bailer was used to sample
the well. Three well volumes were purged from each monitoring well prior to sample collection. The purging was performed
on all wells prior to any sampling activities. Sampling occurred in the same order as purging to allow groundwater turbidity in
each well to reduce prior to sample collection. Groundwater samples were analyzed for volatile organic compounds (VOCs)
via EPA Method SM 6200B and Massachusetts Department of Environmental Protection volatile petroleum hydrocarbon
(VPH). Samples were sent to ESC of Mt. Juliet, TN for analysis.
4.2 Water Supply Well Sampling
NCDENR correspondence dated June 5, 2014 required the sampling of the two water supply wells identified within 500 feet of
the Site (1617 Wrightsville Avenue and 1620 South Memorial Boulevard). As previously documented, the property owner at
1617 Wrightsville Avenue has refused access to sample the well. Prior to the February 2014 sampling event, the property
owner at 1620 South Memorial Boulevard indicated willingness to allow the well to be sampled, but stated that the well was off
due to winterization of the house. The property owner at 1620 South Memorial Boulevard could not be reached prior to the
August 2014 groundwater sampling event to confirm the well’s operational status and permission to sample the well. No
private wells were sampled during the August 2014 sampling event.

4 Field Activities
AECOM Environment 5-1

60263455 August 2014
5.1 Gauging Results
On August 5, 2014, groundwater was encountered between 1.33 feet bgs (MW-9) to 3.27 feet bgs (DW-1). Groundwater flow
was estimated to be toward the east, with a gradient of approximately 0.003 ft/ft (Figure 5-1).
Groundwater gauging data and monitoring well details are summarized on Table 4-1.
5.2 Groundwater Sampling Results
The following compounds were detected above their Title 15A North Carolina Administrative Code 2L Groundwater Standard
(2L Standard) in one or more wells:
 Benzene exceeded its 2L Standard of 1 microgram per liter (µg/L) in well MW-3 (120 µg/L) and MW-5 (230 µg/L)
 Naphthalene exceeded its 2L Standard of 6 µg/L in well MW-3 (110 µg/L) and MW-5 (240 µg/L)
 n-Propylbenzene exceeded its 2L Standard of 70 µg/L in wells MW-3 (82 µg/L) and MW-5 (86 µg/L)
 1,2,4-Trimethylbenzene exceeded its 2L Standard of 400 µg/L in well MW-5 (590 µg/L)
 Total xylenes exceeded its 2L Standard of 500 µg/L in well MW-5 (1,300 µg/L)
 C5-C8 aliphatics exceeded its 2L Standard of 400 µg/L in wells MW-3 (1,500 µg/L) and MW-5 (1,100 µg/L)
 C9-C12 aliphatics exceeded its 2L Standard of 700 µg/L in wells MW-3 (2,300 µg/L) and MW-5 (4,100 µg/L)
 C9-C10 aromatics exceeded its 2L Standard of 200 µg/L in well MW-5 (1,600 µg/L)
Five compounds were only detected below 2L Standards in one or more wells: ethylbenzene, n-butylbenzene, sec-
butylbenzene, isoprorylbenzene, and 1,3,5-trimethylbenzene.
No VOC or VPH compounds were detected in the samples collected from monitoring wells MW-2R, MW-4, MW-6, MW-7, MW-
8, MW-9, and DW-1 during the August 2014 monitoring event.
Groundwater concentrations of VOC and VPH compounds in well MW-3 and MW-5 have decreased since the February 2014
sampling event, with most detected compounds in MW-3 decreasing by more than 50 percent. Since August 2012, prior to the
removal of the Site USTs, concentrations of benzene, naphthalene, toluene, 1,2,4-trimethylbenzene, total xylenes, and VPH
compounds in MW-3 have decreased by more than an order of magnitude.
Analytical results are summarized in Table 5-1. Figures 5-2 to 5-6 include isoconcentration maps for benzene, ethylbenzene,
toluene, xylene, and naphthalene, respectively, and Figure 5-7 is a VPH distribution map. Laboratory analytical reports are
included in Appendix B.
5.3 Private Water Well Sampling Results
As discussed in Section 4.2, no private wells were sampled during the February 2014 sampling event.
5.4 Soil Sampling Results
Historical soil sampling results are included on Table 5-2.
5 Results
AECOM Environment 6-1

60263455 August 2014
No compounds were detected above the 2L Standard in the deep well (DW-1) or the on-site wells located north (MW-2R),
west (MW-4), or south (MW-6) of the UST field. In addition, no compounds were detected in the three off-site, downgradient
wells (MW-7 to MW-9).
Since August 2012, prior to the removal of the Site USTs, groundwater concentrations of several compounds in well MW-3
have decreased by more than an order of magnitude, including benzene, naphthalene, toluene, 1,2,4-trimethylbenzene, total
xylenes, and VPH compounds. Groundwater concentrations in well MW-3 and MW-5 have decreased in both sampling events
since August 2013 (the first sampling event following the UST removal).
The two nearby irrigation wells were not available for sampling during this event. The property owner at 1617 Wrightsville
Avenue refused access. AECOM was unable to successfully contact the property owner at 1620 S. Memorial Boulevard.
Though several VOC and VPH compounds are still present on-site at concentrations above 2L Standards, the plume has been
fully delineated.
Based on the delineation of the plume, declining concentrations in MW-3 and MW-5, and the location of the nearest irrigation
well approximately 250 feet from the Site, AECOM, on behalf of 7-Eleven, requests closure.
