2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
(GMR) documenting the June 28, 2019 sampling of two on-site monitoring wells and four water
supply wells at 163 Service & Grocery, located at 5087 NC Highway 163, West Jefferson, Ashe
County, North Carolina. The groundwater monitoring event was performed based on a June 5,
2019, Task Authorization (TA-04) by the Trust Fund Branch of the Underground Storage Tank
(UST) Section, Division of Waste Management, North Carolina Department of Environmental
Quality (NCDEQ). The work is being performed as part of the State Lead Contract #N17004
between NCDEQ and ATC.

A release was discovered in November 1986 from the UST system consisting of two (2) 2,000-
gallon gasoline, and one (1) 1,000-gallon gasoline USTs. The USTs were removed on May 1, 1989,
and three new 4,000-gallon USTs were installed at the site.

On June 28, 2019, ATC collected groundwater samples from two monitoring wells (MW-1 and
MW-2). The groundwater monitoring wells were gauged for depth to water, purged, and sampled.
Light non-aqueous phase liquid (LNAPL) was not detected in the monitoring well network. ATC
also collected samples from water supply wells located at 5087 NC Highway 163 (site/WSW-1),
5049 NC Highway 163 (WSW-2), 5127 NC Highway 163 (WSW-3), and 5195 NC Highway 163
(WSW-4). The groundwater and water supply well samples were analyzed for volatile organic
compounds (VOCs). Concentrations were compared to the North Carolina Groundwater Standards
(2L Standards; Title 15A, NCAC, Subchapter 2L, Part .0202) and Gross Contaminant Levels
(GCLs). The findings from the groundwater monitoring event indicate the following:

 A concentration of tetrachloroethylene (PCE) was detected below 2L Standards in water
supply well WSW-3 and was the only compound detected in the well;
 The NCDEQ’s July 11, 2019 health risk evaluation for the PCE detected in WSW-3 states
“the detected contaminant did not exceed the applicable water standard. Therefore, no
restrictions on the use of this water were recommended.”
 No VOCs were detected in water supply wells WSW-1, WSW-2, or WSW-4;
 LNAPL was not identified in the monitoring well network;
 A concentration of benzene was detected above the respective 2L Standard in monitoring
well MW-1, and was the only concentration to exceed 2L Standards;
 No VOCs were detected in monitoring well MW-2;

A concentration of PCE was detected in one water supply well (WSW-3) slightly above
detection limits, and below reporting limits. PCE has not been previously detected in any of the
water supply wells or monitoring wells. ATC recommends confirmation sampling for the
presence of PCE in well WSW-3.

The groundwater monitoring event identified remaining impact above 2L Standards in monitoring
well MW-1 next to, and presumed downgradient of the dispenser island. The concentration of
benzene in well MW-1 (8.0 micrograms per liter or µg/L) increased slightly since the previous
groundwater monitoring event (2.0 µg/L); however, the detected concentration is significantly lower
than historical concentrations detected in the well. The June 2019 monitoring event was the second
monitoring event following the installation of the oxygen releasing socks (ORS). Based on the
Groundwater Monitoring Report September 16, 2019

benzene concentration in monitoring well MW-1 and the site conditions, ATC recommends the
following:

 Install additional ORS into well MW-1 to continue reducing the benzene concentration to
levels below 2L Standards and move the site towards closure. Six months following the
installation of the ORS, conduct groundwater monitoring. Continue groundwater
monitoring until VOC concentrations are below 2L Standards for at least two consecutive
monitoring events.
 Evaluate the need to assess soil and groundwater quality conditions at the former UST basin
located south of the current dispenser islands.
 Consider solute transport modeling to evaluate the potential impact to the water supply wells
from the benzene detected in monitoring well MW-1.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The NCDEQ retained ATC to provide environmental consulting services for 163 Service &
Grocery, located at 5087 NC Highway 163, West Jefferson, Ashe County, North Carolina. Figure 1
depicts the site location on a topographic map. The site building operates as a gasoline service
station and convenience store. Municipal water is not available to the site vicinity.

3.2 Site Background
The site formerly utilized a UST system consisting of two (2) 2,000-gallon gasoline USTs, and
one (1) 1,000-gallon gasoline UST. According to the NCDEQ UST database, the USTs were
installed on January 1, 1964. A petroleum release was reported in 1986 originating from a
product line near a dispenser. The USTs were removed on May 1, 1989 and three (3) 4,000-
gallon gasoline USTs were installed at the site. During UST closure, soil sampling indicated
concentrations of total petroleum hydrocarbons (TPH) gasoline range organics (GRO) above
regulatory action levels.

In June 2003, a Phase I Limited Site Assessment (LSA) was completed by Geological Resources,
Inc. (GRI). Monitoring well MW-1 was installed during the Phase I LSA activities and
monitoring well MW-2 was installed in May 2004. Initial groundwater monitoring indicated
exceedances of the 2L Standards in monitoring well MW-1. No contaminants were detected in
monitoring well MW-2, or any of the nearby water supply wells. A surface water sample from
Beaver Creek did not contain any detectable concentrations of petroleum constituents. Four
water supply wells were identified within 1,000 feet of the site.

Subsequent groundwater monitoring events have been conducted at the site in 2005, 2006, 2009,
2010, 2011, 2012, and 2013. On October 2, 2017, ATC completed groundwater monitoring of
site monitoring wells MW-1 and MW-2 and water supply wells WSW-1, WSW-2, and WSW-4.
Groundwater monitoring detected concentrations of benzene and naphthalene above NC 2L
Standards in well MW-1. No concentrations of petroleum constituents were detected in well
MW-2 or any of the sampled water supply wells.

On May 22, 2018, ATC installed three Provectus® ORS, contained within canisters, into the
water column of monitoring well MW-1. On December 20, 2019, ATC conducted groundwater

monitoring of the monitoring well network to gauge effectiveness of the ORS. Benzene was
detected above 2L Standards in monitoring well MW-1 and was the only concentration above 2L
Standards. It appeared that the ORS had a beneficial impact in reducing groundwater
concentrations.

3.3 Site and Regional Geology

According to the Geologic Map of North Carolina, produced by the State of North Carolina in
1985, the site lies in the Ashe Metamorphic Suite and Tallulah Falls Formation of the Blue Ridge
Belt of North Carolina. The rock type at the site has been identified as muscovite-biotite gneiss.
In most areas, the upper Blue Ridge subsurface consists of unconsolidated residual soil,
variously known as residuum, saprolite, or partially weathered rock (PWR) that has developed
from in-place weathering of the underlying metamorphic bedrock. The residual soils vary in
consistency and depth based on local conditions. Bedrock can be found at depths ranging from
the surface as outcrops down to greater than 100 feet in areas of easily weathered rock types.
Areas near streams and rivers in the Blue Ridge may also contain alluvium deposited during
flood events. No site specific soil information was available to ATC.

3.4 Site and Regional Hydrogeology

The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers
to as deep as 50 feet or more beneath upland surfaces in some parts of the Blue Ridge. The depth
to groundwater was 3.82 feet below top of casing (ft toc) in monitoring well MW-1 and 2.85 ft
toc in monitoring well MW-2 during the June 28, 2019 monitoring event.

Water in the alluvium or unconsolidated residual material, including saprolite and PWR, usually
behaves as an unconfined aquifer, or water table, and will yield water with head elevation
equivalent to the first elevation where water was encountered. Permeability varies with lithology
and is typically relatively low in residual soils, with higher permeability in saprolite or PWR due
to relict rock texture and variable susceptibility to weathering exhibited by different minerals in
the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with
local topographic conditions and is toward local drainage features. Based topography,
groundwater is expected to flow toward the west-southwest toward Beaver Creek (a Class C,
Trout Stream), located approximately 120 feet from the dispenser islands.

The bedrock fractures or other planar features of the Blue Ridge Physiographic Province
generally constitute the bedrock aquifer, with the surrounding rock material being effectively
impermeable. Along with fractures, contacts between rock bodies probably constitute zones of
significant groundwater occurrence in the bedrock. The surrounding material and overlying
residuum tend to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water
and soil weight normally results in pressure that causes water in a borehole, which intersects a
fracture or other feature, to rise above the elevation of the fracture or feature. Most modern
water supply wells in the Blue Ridge consist of a casing set through the residual soils into the
upper bedrock followed by an open borehole into the bedrock where water bearing fractures
were encountered during the drilling. Except for sampling of the site and nearby water supply
wells, evaluation of bedrock water quality or hydrology was beyond the scope of the GMR.

4.0 GROUNDWATER CHARACTERIZATION
4.1 Water Supply Wells
Four water supply wells were previously identified within 1,000 feet from the site. Figure 2
depicts the location of the water supply wells on an aerial overlay with radial distances from the
site. Table 1 summarizes water supply well information. ATC collected water supply well
samples from water supply wells located at 5087 NC Highway 163 (site/WSW-1), 5049 NC
Highway 163 (WSW-2), and 5127 NC Highway 163 (WSW-3), and 5195 NC Highway 163
(WSW-4).

Each water supply well sample was collected from outdoor spigots. Each water supply well was
sampled after the well was allowed to purge for fifteen minutes. The water samples were
collected in laboratory-supplied, preserved containers; entered into chain of custody control;
placed on ice; and shipped to North Carolina accredited SGS North America Inc. (SGS) in
Orlando, Florida. A concentration of PCE (0.25 J µg/L) was detected in well WSW-3 below the
2L Standard of 0.7 µg/L, and Maximum Contaminant Level (MCL) of 5 µg/L. PCE has not been
detected previously for any water supply well or monitoring well. The concentration is an
estimated concentration below reporting limits but above detection limits. Table 2 summarizes
current water-supply well analytical results, and Table 3 indicates historical water supply well
analytical results. Field notes from the June 28, 2019, groundwater monitoring event are
presented in Appendix A.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory reports was conducted. During the review, it was found that the samples were received
from the laboratory in acceptable condition and properly preserved. The samples were analyzed
within correct holding times and reported within the lab report, and the chain of custody was
properly completed by all parties. The laboratory QC report shows that 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. A field blank was also analyzed during the groundwater monitoring event and no
compounds were detected in the field blank. Refer to the laboratory reports in Appendix B for
details regarding QA results for the laboratory samples and any noted exceptions. Overall, ATC
concludes that the laboratory results are usable and any exceptions do not significantly impact the
conclusions presented in this report.

4.2 Groundwater Levels
On June 28, 2019, groundwater monitoring was conducted for the site monitoring well network.
Water levels were gauged in monitoring wells MW-1 and MW-2. LNAPL was not observed in
the monitoring well network. Figure 3 depicts a site map. Monitoring well construction details
are included in Table 4. An oil/water interface probe was used to measure the depth to
groundwater from the top of well casing (toc). Depth to groundwater elevation data are
summarized in Table 4. Top of casings for the monitoring wells have not been surveyed.
Groundwater flow is expected to follow topography. Based on the USGS topographic map,
groundwater is expected to flow to the west southwest toward Beaver Creek. Field notes from
the June 28, 2019, groundwater monitoring event are presented in Appendix A.

4.3 Groundwater Quality

On June 28, 2019, groundwater samples were collected from monitoring wells MW-1 and MW-2.
During sampling activities, a three-volume well purge was implemented prior to groundwater
sample collection to ensure collection of representative groundwater samples. The groundwater
samples were collected in laboratory-supplied, preserved containers; entered into chain of custody
control; placed on ice; and shipped to SGS North America, Inc. The groundwater samples were
analyzed by EPA Method 6200B for VOCs including petroleum constituents. The analytical report
is included in Appendix B.

Groundwater field parameters including temperature, dissolved oxygen, conductivity, and pH were
measured during the monitoring event. Field parameter readings for each well are presented in
Table 5. Current and historical groundwater analytical results are summarized in Tables 2 and 3,
respectively. The groundwater analytical results were compared to the 2L Standards and GCLs.
Groundwater analytical results indicated the following:

 LNAPL was not identified in the monitoring well network.
 A concentration of benzene (8.0 µg/L) was detected above the respective 2L Standard in
monitoring well MW-1, and was the only concentration to exceed 2L Standards.
 No VOCs were detected in monitoring well MW-2.

Groundwater analytical results are shown on Figure 4.

The laboratory QA/QC measures outlined in section 4.1 apply to this section.

5.0 CONCLUSIONS AND RECOMMENDATIONS

On behalf of the Trust Fund Branch of the UST Section, ATC has completed a GMR
documenting a June 28, 2019, monitoring event for 163 Service & Grocery, located at 5087
Highway 163, West Jefferson, Ashe County, North Carolina.

A concentration of PCE was detected in one water supply well (WSW-3) at an estimated
concentration of 0.25 µg/L, compared to the 2L Standard of 0.7 µg/L and the MCL of 5 µg/L.
PCE has not been previously detected in any of the water supply wells or monitoring wells. ATC
recommends confirmation sampling for the presence of PCE in well WSW-3. The health risk
evaluation issued by the NCDEQ on July 11, 2019 (Appendix C) includes the following
recommendation:

“The detected contaminant did not exceed the applicable water standard. Therefore, no
restrictions on the use of this water were recommended.”

The groundwater monitoring event identified remaining impact above 2L Standards in monitoring
well MW-1 next to, and presumed downgradient of the dispenser island. The concentration of
benzene in well MW-1 has slightly increased since the previous groundwater monitoring event;
however, the detected concentration is significantly lower than historical concentrations detected in

the well. The June 2019 monitoring event was the second monitoring event following the
installation of the oxygen releasing socks (ORS). Based on the benzene concentration in monitoring
well MW-1 and the site conditions, ATC recommends the following:

 Install additional ORS into well MW-1 to continue reducing the benzene concentration to
levels below 2L Standards and move the site towards closure. Six months following the
installation of the ORS, conduct groundwater monitoring. Continue groundwater
monitoring until VOC concentrations are below 2L Standards for at least two consecutive
monitoring events.
 Evaluate the need to assess soil and groundwater quality conditions at the former UST basin
located south of the current dispenser islands.
 Consider solute transport modeling to evaluate the potential impact to the water supply wells
from the benzene detected in monitoring well MW-1.

HEALTH RISK EVALUATION

July 11, 2019 TO: Herb Berger NC UST Section

RE: Health Risk Evaluation Incident Number: 3320 Jackie Wade Noblett Well Sampling Results 163 Service and Grocery
West Jefferson, NC
During this sampling event, one contaminant was detected in the well water. The standards used to determine if the water is suitable for drinking and cooking are the United States Environmental Protection Agency’s Maximum Contaminant Levels (MCLs) or, if no MCLs exist, North Carolina Groundwater Standards
(2L).
If the contaminant concentration exceeds the applicable standard for using the water for drinking and cooking, the contaminant concentration is further analyzed to determine if the water is suitable for other household uses, such as showering, bathing, washing dishes, flushing toilets, and hand washing. The chart
below compares the detected contaminant concentration with the applicable standard:
Sample ID Contaminant Concentration (µg/L) MCL (µg/L) 2L (µg/L)
FA65658-5 Tetrachloroethylene 0.25 5
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion.

RECOMMENDATION: The detected contaminant did not exceed the applicable water standard. Therefore, no restrictions on the use of this water are recommended at this time.
