2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Federal/State-Lead Groundwater
Monitoring Report (GMR), documenting a December 12, 2017, monitoring event of eight on-site
monitoring wells and surrounding water supply wells at the former Moore’s Exxon, located at 7390
NC Highway 16 in Glendale Springs, Ashe County, North Carolina. The GMR is being performed
based on a November 20, 2017, Task Authorization (TA-1) 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 from a former kerosene UST at the site was discovered during its removal in 1990. A
subsequent release was identified in 1991 during the removal of one of the site’s former gasoline
USTs. The site has been demolished and is now the site of the Glendale Springs Volunteer Fire
Department. This GMR documents impact conditions related to the former UST system.
As part of this Task Authorization, ATC collected groundwater samples from eight site-related
monitoring wells. The site groundwater monitoring wells were gauged for depth to water, sampled,
and analyzed for volatile organic compounds (VOCs). ATC also collected samples from three water
supply wells and analyzed each sample for VOCs. Water supply well WSW-3 was not sampled due
to the water being turned off at the property. The findings from the monitoring event indicate the
following:
Free product was not identified in the monitoring well network;
Monitoring well MW-1 contained a concentration of benzene above the Gross
Contamination Level (GCL);
Monitoring well MW-1 also contained concentrations of nine constituents above the North
Carolina Groundwater Standards (2L Standards; Title 15A, NCAC, Subchapter 2L, Part
.0202);
Monitoring wells MW-1R and MW-3R contained detectable concentrations petroleum
constituents below 2L Standards;
Monitoring wells MW-5, MW-10R, MW-11, MW-12, and MW-13 did not contain
detectable concentrations of petroleum constituents;
Based on the limited monitoring well network, groundwater appears to flow to the east-
northeast;
Concentrations of MTBE, 2-butanone (MEK), and diisopropyl ether (DIPE) were
detected below 2L Standards in water supply well WSW-7414; and
No detectable concentrations of petroleum compounds were identified in water supply
wells WSW-26 or WSW-121.
Appreciable remaining subsurface impact by petroleum VOCs above GCLs and 2L Standards is
present in groundwater beneath the site. ATC recommends a ground penetrating radar (GPR) survey
to investigate the possibility of additional tanks at the site. ATC also recommends drilling and
sampling of a soil boring in the former UST pit adjacent to monitoring well MW-1 to assess the
vertical extent of petroleum-impacted vadose-zone soil. Following soil assessment, ATC would
then develop a strategy to remediate this area.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The NCDEQ retained ATC to provide environmental consulting services for the former Moore’s
Exxon, which is located at 7390 NC Highway 16 in Glendale Springs, Ashe County, North
Carolina. Figure 1 depicts the site on a topographic map. The former site building has been
demolished. The site is currently occupied by the Glendale Springs Volunteer Fire Department.
Municipal water is not provided to the surrounding area and properties within 1,000 feet of the site
obtain potable water from private supply wells. Twenty-six water supply wells have been previously
identified within 1,000 feet of the site.
3.2 Site Background
Six USTs were formerly associated with the site. Two (2) 2,000-gallon gasoline USTs, one (1)
550-gallon kerosene UST, one (1) 3,000-compartmentalized gasoline UST, one (1) 1,000-gallon
gasoline UST, and a heating oil UST of unknown quantity and size. A release of 50 gallons of
kerosene was originally reported in 1990 during the removal of the 550-gallon kerosene UST.
Approximately 10 yards of soil were excavated to remove contamination from the release. Due
to the elevated levels of total petroleum hydrocarbons (TPH) in the closure assessment soil
samples, a new release was attributed to one of the 2,000-gallon gasoline USTs. A third release
was likely associated with the 1,000-gallon gasoline UST due to the presence of a mixture of
petroleum and water and several holes in the tank. In 1997, over one foot of free phase product
was gauged in monitoring well MW-1, which is located near the former 2,000-gallon UST
associated with the release.
Enviro-Tank, Inc. conducted an investigation of the tank basins at the west, south, and east sides
of the former building in 1990. Samples collected from the eastern side of the building in the
kerosene tank basin yielded total petroleum hydrocarbons (TPH) concentrations of 8,850
milligrams per kilogram (mg/kg).
During the removal of one of the 2,000-gallon gasoline USTs and the in-place abandonment of
one of the other 2,000-gallon USTs, soil samples were collected, which indicated a second
release occurred at the site. TPH concentrations of 24 mg/kg were detected in the soil sample
collected at the southern boundary of the site.
Soil samples were collected at the southern and eastern edges of the site at approximate depths of
13.5 to 15 feet in May 1996 by Law Environmental. Laboratory analysis indicated that two
samples, located near one of the 2,000-gallon gasoline USTs and the 1,000-gallon gasoline UST
at the southern boundary of the site, contained TPH concentrations of 9,700 mg/kg and 2,000
mg/kg.
In June 1996, the North Carolina Department of Transportation (NCDOT) discovered the
presence of free phase petroleum during an easement assessment. In October 1996, Salem
Environmental installed four groundwater monitoring wells (MW-1 through MW-4) to 25 feet
below ground surface (ft bgs). Two AFVR events were reportedly performed by Seagraves Oil

Company, at the locations of monitoring wells MW-1 and MW-2; however, no documentation of
the events was provided.
In March, April, June, and July 1997, additional monitoring wells MW-5 through MW-10 were
installed by Salem Environmental. In July 1997, over one foot of free phase product was
detected in monitoring well MW-1. Prior to an AFVR event in 1998, 2.73 feet of free phase
product was detected.
In June 2000 four soil samples and a composite sample were collected by TRC Triangle during
the removal of the 3,000-gallon gasoline UST. The June 2000 samples were below detection
limits for TPH analysis. Additional monitoring wells MW-11 and MW-12 were installed
upgradient of the source area, and monitoring well MW-13 was installed at the location of the
former source area.
In July 2002, the previously abandoned 1,000-gallon gasoline UST was removed from the site.
Environmental Investigations, Inc. collected two soil samples during the removal process. TPH
was detected at concentrations ranging from 730 mg/kg to 3,400 mg/kg.
In a monitoring report dated December 29, 2003, Geonetics Corporation stated that most of the
monitoring wells had been destroyed. During an April 13, 2010, groundwater monitoring event,
monitoring wells MW-11 and MW-12 were the only monitoring wells located.
In February 2011, property access for replacement monitoring well installation was granted by
the Glendale Springs Fire Chief and Terry Sheets, an adjacent property owner. Monitoring wells
MW-1R and MW-3R were installed on-site, and a downgradient monitoring well, MW-10R was
also installed. Two of the wells that were thought to have been destroyed were located (MW-1
and MW-5). Force Environmental sampled monitoring wells MW-1R, MW-3R, MW-5, MW-
10R, MW-11, and MW-12. Monitoring well MW-1 contained detectable free product and was
not sampled. The analytical results from the sampling event indicated concentrations greater than
the North Carolina 2L Standards for Groundwater in monitoring wells MW-1R and MW-3R.
ATC performed groundwater monitoring activities at the site on July 8, 2014. Results from the
groundwater monitoring event indicated VOC impact, including free product detected in
monitoring well MW-1 at a thickness of 0.11 feet. Petroleum constituents were detected in all of
the sampled monitoring wells below 2L Standards except monitoring well MW-3R which
contained concentrations of benzene, naphthalene, and n-propylbenzene exceeding 2L Standards.
During the groundwater monitoring event, ATC also performed a receptor survey update which
identified water supply wells within 1,500 feet. Based on the survey and lack of municipal water
service in the area, developed properties within 1,500 feet of the site are considered possible
receptors. At the conclusion of the groundwater monitoring event, ATC recommended the
installation of an additional monitoring well to further assess and delineate the petroleum
subsurface impact.
On November 7, 2014, ATC and a subcontractor performed a ten-hour AFVR event using
monitoring wells MW-1 and MW-3R as extraction points. Prior to performing the AFVR event,
wells MW-1 and MW-3R were gauged for liquid levels, and no free product was detected in the
monitoring wells. The AFVR event generated approximately 673 gallons of petroleum impacted

groundwater. The AFVR subcontractor did not provide vapor concentration measurements. ATC
also installed groundwater monitoring well MW-13 to the south of the site to further delineate
the subsurface impact. Following the installation of the monitoring well, well MW-13 was
sampled and no detectable concentrations of petroleum impact were identified.
On July 8, 2015, ATC completed a groundwater monitoring event of the monitoring well
network and water supply wells within 500 feet of the site. Analysis of the groundwater indicated
a concentration of benzene in monitoring well MW-1 above GCLs. Additional compounds above
2L Standards were identified in monitoring wells MW-1 and MW-3R. Water supply well
analytical data indicated MTBE impact below 2L Standards in water supply wells WSW-26 and
WSW-7414. Diisopropyl ether was also identified in water supply well WSW-7414 at a
concentration below 2L Standards. Acetone was identified in each sampled water supply well.
Additional confirmation sampling did not identify acetone in the water supply wells, and the
presence of acetone was likely attributable to laboratory cleaning methods and not site impact.
Based on the concentrations identified in the water supply well samples, the NCDEQ performed
a Health Risk Evaluation for the wells in which no restrictions were recommended on the use of
the wells.
On March 1, 2016, ATC completed a monitoring event which indicated benzene impact above the
GCL in well MW-1. Ten additional petroleum constituents were identified in monitoring well MW-
1 at concentrations above 2L Standards. During the July 8, 2015, groundwater monitoring event,
monitoring well MW-3R contained concentrations of four constituents above 2L Standards;
however, during March 2016 groundwater monitoring event, no concentrations of petroleum
constituents identified in monitoring well MW-3R exceeded 2L Standards. Monitoring wells MW-
1R, MW-5, MW-10R, MW-11, MW-12, and MW-13 did not contain detectable concentrations of
petroleum compounds.
3.3 Site and Regional Geology
According to the Geologic Map of North Carolina, dated 1985, the property lies within the Blue
Ridge Physiographic Province, in the Alligator Back Formation of the Ocoee Supergroup. The
crystalline metamorphic rock of the Alligator Back Formation is at the site is a finely laminated
to thin-layered with local occurrence of other metamorphic rock types. 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. Sites near streams and rivers in the Blue
Ridge may also contain alluvium deposited during flood events.
Monitoring well installation information from an August 1, 1997, Comprehensive Site
Assessment by Geonetics Corporation indicated that the site subsurface consisted of saprolite. A
monitoring well was installed into the deep aquifer (MW-9) was screened in fractured bedrock
which was encountered at approximately 50 feet ft bgs. Bedrock monitoring well MW-9 was
destroyed during road widening activities. Historical sampling of monitoring well MW-9 did not
indicate petroleum impact to the bedrock well.

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. ATC
encountered groundwater at depths ranging from 6.60 feet to 25.02 feet below the tops of casing
in the monitoring wells at the site during the December 12, 2017, 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 on the existing site wells, the
groundwater flow is to the east-northeast.
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 attempted sampling of 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
On December 12, 2017, ATC collected groundwater samples from water supply wells WSW-26
(107 Trading Post Road), WSW-121 (121 Trading Post Road), WSW-7414 (7414 NC Highway
16). ATC attempted to sample water supply well WSW-3 (231 J W Luke Road); however, water
was turned off at the property. Table 1 summarizes water supply well information. Figure 2
depicts the locations of the water supply wells. Field notes from the December 12, 2017,
groundwater sampling event are presented in Appendix A.
The water supply well samples were collected in laboratory-supplied, preserved containers;
entered into chain of custody control; placed on ice; and shipped to North Carolina accredited
Con-Test Analytical Laboratory in East Longmeadow, Massachusetts. The water samples were
analyzed by EPA Method 6200B for VOCs including petroleum constituents. The analytical
report is included in Appendix B.
Current supply well analytical results are summarized in Table 2. Historical supply well
analytical results are shown in Table 3. Analytical results were compared to the 2L standards.
Supply well analytical results indicated a concentration of MTBE below 2L Standards in water

supply well WSW-7414 (0.48 J µg/L). Concentrations of 2-butanone (MEK) and diisopropyl
ether (DIPE) were identified in water supply well WSW-7414 below 2L Standards at
concentrations of 3.7 J µg/L and 0.58 µg/L, respectively. No detectable concentrations of
petroleum compounds were identified in water supply wells WSW-26 or WSW-121.
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. ATC also collected a field blank during the groundwater monitoring event, and no
constituents were detected in the 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 December 12, 2017, groundwater monitoring was conducted using the site monitoring well
network. Water levels were gauged in monitoring wells MW-1, MW-1R, MW-3R, MW-5, MW-
10R, MW-11, MW-12, and MW-13. Figure 3 depicts a site map and site characteristics. An
oil/water interface probe was used to measure the depth to groundwater from the top of well
casing (TOC). Groundwater elevation was then calculated based on TOC elevations, which are
referenced to an arbitrary elevation of 100.00 feet. Free product was not encountered in the
monitoring well network. Groundwater elevation data is summarized in Table 4. A groundwater
contour map depicting groundwater flow is presented in Figure 4. The contour map indicates
that groundwater flows to the east-northeast. Field notes from the December 12, 2017,
groundwater monitoring event are presented in Appendix A.
4.3 Groundwater Quality
On December 12, 2017, groundwater samples were collected from monitoring wells MW-1, MW-
1R, MW-3R, MW-5, MW-10R, MW-11, MW-12, and MW-13. During sampling activities, if
sufficient water was available, a three-volume purge was implemented prior to groundwater sample
collection to ensure representative groundwater samples. 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 Con-Test Analytical Laboratory in East Longmeadow,
Massachusetts. 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, pH, and
oxidation reduction potential were measured during the monitoring event. Field parameter readings
for each well are presented in Table 5. Current groundwater analytical results are summarized in
Table 6. Historical groundwater analytical results are shown in Table 7. The groundwater analytical

results were compared to the 2L Standards and GCLs. Groundwater analytical results indicate the
following:
Free product was not observed in the monitoring well network;
Monitoring well MW-1 contained a concentration of benzene (8,900 µg/L) above the GCL
of 5,000 µg/L;
Monitoring well MW-1 also contained concentrations of diisopropyl ether (2,200 µg/L),
ethylbenzene (6,200 µg/L), isopropylbenzene (180 J µg/L), n-propylbenzene (410 J µg/L),
styrene (500 µg/L), toluene (120,000 µg/L), 1,2,4-trimethylbenzene (3,400 µg/L), 1,3,5-
trimethylbenzene (1,000 µg/L), and total xylenes (34,000 µg/L) above 2L Standards;
Monitoring well MW-1R contained detectable concentrations of three petroleum
constituents below 2L Standards;
Monitoring well MW-3R contained detectable concentrations of thirteen petroleum
constituents below 2L Standards;
Monitoring wells MW-5, MW-10R, MW-11, MW-12, and MW-13 did not contain
detectable concentrations of petroleum constituents; and
Based on the monitoring well network, groundwater appears to flow to the east-northeast.
Figure 5 depicts the compounds above 2L Standards.
The QA and QC measures and conditions applicable to the water supply well monitoring as
discussed in section 5.1, also apply to the monitoring well sampling.
5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed a GMR documenting
a December 12, 2017, monitoring event for the former Moore’s Exxon, located at 7390 NC
Highway 16, in Glendale Springs, Ashe County, North Carolina. Results from the groundwater
monitoring event indicate appreciable remaining benzene impact above the GCL in monitoring well
MW-1. Nine additional petroleum constituents were identified in monitoring well MW-1 at
concentrations above 2L Standards. Monitoring wells MW-5, MW-10R, MW-11, MW-12, and
MW-13 did not contain detectable concentrations of petroleum compounds. Concentrations detected
during the December 12, 2017, monitoring event are consistent previous findings. Continued
elevated petroleum concentrations found in groundwater collected from monitoring well MW-1
indicates the presence of a petroleum mass in the vadose zone in the area around monitoring well
MW-1 (former UST location).
Based on the information provided in this report, ATC recommends the following:
A GPR survey to investigate the possibility of additional tanks at the site;
Drilling and sampling of a soil boring in the former UST pit adjacent to monitoring well
MW-1 to assess the vertical extent of petroleum-impacted vadose-zone soil;
Based on the information of the soil assessment, ATC would then develop a strategy to
remediate this area.
