2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
(GMR) documenting a Mobile Multi-Phase Extraction (MMPE) event conducted from May 6, 2019
to May 10, 2019, and a June 6, 2019 groundwater monitoring event of seven monitoring wells and
six water supply wells associated with the Williams Grocery site, located at 2425 US Highway 21,
Hamptonville, Yadkin County, North Carolina. The groundwater monitoring event was performed
based on an March 26, 2019, Task Authorization (TA-02) 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 February 1994, from the UST system during removal of a 2,000-gallon
gasoline UST and a 500-gallon kerosene UST. Three 550-gallon gasoline USTs were filled in-place
with concrete, and were later removed.

From May 6, 2019 to May 10, 2019, a 96-hour MMPE was performed at the site. Prior to the
completion of the MMPE event, groundwater samples were collected from wells MW-1, MW-3,
and recovery well RW-1 to serve as comparison for post-MMPE sampling. Monitoring wells
MW-1, MW-3, and recovery well RW-1 were used as the extraction points for the MMPE.
During the MMPE event, air sparge well AS-1 was also utilized by connecting an air
compressor, to aid in remediation. A total of 4,869 gallons of petroleum impacted groundwater
was generated during the MMPE event. Calculations for MMPE emissions resulted in an estimated
43.82 gallons (269.57 pounds) of petroleum hydrocarbons being recovered as vapors. Light non-
aqueous phase liquid (LNAPL) was not encountered before or following the MMPE event.

Subsequent to the MMPE event, on June 6, 2019, ATC collected groundwater samples from the site
monitoring well network. The groundwater monitoring wells were gauged for depth to water,
purged, and sampled. LNAPL was not detected in the monitoring well network. ATC also collected
samples from water supply wells WSW-1, WSW-2, WSW-5, WSW-6, WSW-7 and WSW-9. Wells
WSW-3 and WSW-10 could not be sampled due to occupant absence. 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:

 Eleven water supply wells are located within 1,000 feet of the source area. Based on the
proximity to the source area to the water supply wells, the historical groundwater and
water supply well sampling results, and the groundwater flow direction, water supply
wells WSW-1, WSW-3, and WSW-5 appear to be the greatest at-risk wells.
 Water supply wells WSW-2, WSW-7, and WSW-9 contained one or more compounds at
concentrations less than the 2L Standards. Toluene in WSW-2 and methyl-tert butyl ether
(MTBE) in WSW-9 were the only petroleum constituents detected in the water supply
well samples. Methyl ethyl ketone (MEK) was detected in WSW-9, and has been
detected in site monitoring wells MW-1 and MW-3. The source of the constituents
detected in the water supply wells has not been definitively identified as the Williams

Grocery UST release. No compounds were detected in water supply wells WSW-1,
WSW-5, or WSW-6.
 LNAPL was not identified in the groundwater monitoring network.
 Monitoring wells MW-1, MW-3, and recovery well RW-1 contained one or more
compounds at concentrations exceeding the GCLs. Additional compounds were detected in
wells MW-1, MW-3, and recovery well RW-1 at concentrations exceeding the 2L
Standards.
 VOCs were not detected in wells MW-2, MW-4, MW-5, or MW-6 at concentrations
exceeding the 2L Standards.
 Groundwater flow is primarily to the east-northeast, with a component of flow to the south-
southeast.
 The extent of impact exceeding the 2L Standards is not defined to the north toward WSW-3
(345 feet from the source area), to the west toward water supply WSW-1 (105 feet west of
the source area), or to the southeast toward water supply wells WSW-7 (630 feet from the
source area), WSW-9, and WSW-10.
 The nearest downgradient water supply well to the east-northeast is WSW-4 (820 feet from
the source area), with shallow monitoring wells MW-5 and MW-6 located between the
water supply well and the site with no petroleum constituents at concentrations exceeding
the 2L Standards since June 2012 (MW-5). No petroleum constituents have been detected
in water supply well WSW-4 since sampling of the well began in June 2003.

Based on the calculations from the MMPE event, it appears that the MMPE was effective in mass
removal of petroleum hydrocarbons. However, only slight reductions in dissolved phase
concentrations were realized and concentrations in the monitoring well network continue to exceed
GCLs. Evaluation of benzene concentrations in wells MW-1, MW-3, and RW-1 does not indicate a
decreasing trend, and it does not appear that MMPE and air sparging is an effective practice in
reducing dissolved phase concentrations in these wells. However, historically, concentrations in
downgradient monitoring well MW-5 have indicated decreasing concentrations that may be due in
part to the remedial actions.

Based on the remaining dissolved phase concentrations in the groundwater, ATC recommends
evaluation of chemical injection options to increase reduction of dissolved phase concentrations.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The NCDEQ retained ATC to provide environmental consulting services for Williams Grocery,
located at 2425 US Highway 21, Hamptonville, Yadkin County, North Carolina. Figure 1 depicts
the site location on a topographic map. The former Williams Grocery building was demolished
several years ago, and the residence located southeast of the former UST system was demolished in
early 2017. There are two apartments located on the property, to the southwest of the former
William Grocery building.

3.2 Site Background
The site formerly utilized a UST system consisting of one (1) 2,000-gallon gasoline UST, three
(3) 550-gallon gasoline USTs, and one (1) 550-gallon kerosene UST. The 2,000-gallon gasoline

UST and the 550-gallon kerosene UST were removed in February, 1994. The three 550-gallon
gasoline USTs were initially closed in place due to stability of nearby foundations. Closure
sampling was performed during tank closure activities. Total petroleum hydrocarbon (TPH)
concentrations ranged from 42 parts per million (ppm) as gasoline range organics (GRO), to
25,000 ppm as GRO and diesel range organics (DRO).

Groundwater monitoring wells MW-1 through MW-3 were installed and sampled in November,
1996. LNAPL was detected in monitoring wells MW-1 and MW-3 during initial sampling.
Petroleum compounds were detected in monitoring well MW-2 at concentrations that exceeded
the 2L Standard.

The three USTs that were filled with concrete were removed in February 1997. During
excavation activities, 144 tons of petroleum impacted soils were removed. Vertical and
horizontal extent sampling detected concentrations ranging from 2,500 ppm to 13,000 ppm TPH
GRO.

Monitoring wells MW-4 through MW-11 were installed and sampled in April 1998. Initial
sampling indicated concentrations above 2L Standards in monitoring wells MW-4, MW-5, MW-
8, and MW-9.

Monitoring well RW-1 was installed in June 2010 in the source area. Initial sampling of well
RW-1 showed concentrations of benzene, MTBE, and 1,2-dibromoethane above 2L Standards
and GCLs. Eleven additional compounds were detected above 2L Standards in the well.

A Groundwater Monitoring Report completed by TerraQuest in June 2012, identified 11 potable
water supply wells within 1,000 feet of the site. According to prior reports, a Point-of-Entry
(POE) filtration system was installed on water supply well WSW-1.

Subsequent groundwater monitoring events have been performed at the site. Monitoring wells
MW-7 through MW-11 could not be located for multiple sampling events. The groundwater
monitoring event, performed in 2015, detected LNAPL in monitoring wells MW-3 and RW-1.
Concentrations of benzene, MTBE, and 1,2-dibromoethane were detected above GCLs in
monitoring well MW-1. Concentrations of petroleum compounds exceeded 2L Standards in
monitoring well MW-2.

According to a Groundwater Monitoring Report completed by S&ME, approximately 18
aggressive fluid vapor recovery (AFVR) events were completed at the site from June 1997,
through November 1998. According to prior reports provided to ATC, approximately four
MMPE events were performed at the site from July 2001 through August 2004. An MMPE event
was also completed at the site as part of S&ME’s 2016 field activities from June 24, 2016, to
June 24, 2016. According to data from the Groundwater Monitoring Report, the five MMPE
events generated 2,068 gallons of hydrocarbons as LNAPL and as vapors.

ATC conducted groundwater monitoring in November, 2017. Detected concentrations exceeded
GCLs in wells MW-1 and MW-3. Additional impact above 2L Standards was detected in wells
MW-1, MW-2, MW-3, and recovery well RW-1.

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 Brushy Mountains of the Inner Piedmont Physiographic Province. The
rock type at the site has been identified as metamorphosed granitic rock. The shallow subsurface
in most areas of the Piedmont contains residual soil overburden, including structure-free
residuum, saprolite, and partially weathered rock (PWR) that derive from in-place weathering of
the crystalline bedrock. In areas near creeks and rivers, alluvium derived from weathered
residual soil is often present and such material may be present near drainages at the property.
Saprolite and PWR typically contain some relict structures from the original rock material. Depth
to rock ranges from ground surface at occasional outcrops to depths greater than 100 feet in areas
of easily weathered rock.

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 Piedmont. Water in the
alluvium or unconsolidated residual material, including saprolite and PWR, usually behaves as
an unconfined, or water table, aquifer 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.

The bedrock fractures or other planar features 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. Such features may not occur on predicable trends, at the same elevations, or
even be present or directly connected in separate boreholes. In areas adjacent to creeks the
bedrock groundwater generally discharges to the residuum or alluvium and then into the surface
water. In upland areas away from surface water drainages, the bedrock aquifer is generally
recharged by downward infiltration of residuum or alluvial aquifer water at locations where
fractures intersect the bedrock surface.

Based on groundwater gauging data from the June 6, 2019, groundwater monitoring event,
groundwater is expected to flow to the east-northeast and to the south-southeast. Since the site is
situated on a topographic ridge, groundwater flow directions may change with changes in
groundwater levels or precipitation. Groundwater depth ranged from approximately 17.87 feet
below ground surface (ft bgs) in monitoring well MW-6, to 20.98 ft bgs in monitoring well MW-
3.

4.0 MOBILE MULTI-PHASE EXTRACTION EVENT
As part of TA-2, Advanced Environmental Services, Inc. (Advanced) was contracted to conduct
a 96-hour MMPE event. From May 6, 2019 to May 10, 2019, ATC and Advanced conducted a
96-hour MMPE event that began at 1130 on May 6, 2019 and ended at 1130 on May 10, 2019.
Monitoring wells MW-1, and MW-3, and recovery well RW-1 were used as the extraction points
for the MMPE event. During the MMPE event, air sparge well AS-1 was also utilized by
connecting an air compressor, to aid in remediation. Prior to performing the MMPE event, the
wells used for extraction were gauged for liquid levels using an oil/water interface probe.
LNAPL was not encountered at the beginning of the MMPE event. Groundwater gauging data is
summarized in Table 1. ATC also collected representative groundwater samples from wells
MW-1 and MW-3, and recovery well RW-1 and analyzed the groundwater for VOCs by EPA
Method 6200, to serve as a baseline for comparison for post-MMPE sampling.

During MMPE activities, a liquid ring vacuum pump unit is plumbed to the designated extraction
point, and a drop pipe is extended into the well through an airtight seal at the top of the well
casing (TOC) and into the water column. Throughout the MMPE process, a cone of depression
and a zone of lower pressure forms around a designated recovery point by drawing down the
groundwater surface levels, thus causing impacted water surrounding the recovery point to be
extracted. Soil petroleum vapor within the cone of depression and the overlying vadose zone are
also removed as vapor by air passing through the soil. Depth to water and well head pressures
were measured in monitoring wells MW-2 and MW-4 during the MMPE event.

A total of 4,869 gallons of petroleum impacted groundwater was recovered during the MMPE
event. During fluid recovery, measurements for organic vapors utilizing a photoionization detector
(PID), velocity, relative humidity, temperature, and vacuum pressure were collected. Calculations
for MMPE emissions resulted in an estimated 43.82 gallons (269.57 pounds) of petroleum
hydrocarbons being recovered as vapors. Advanced fitted magnahelic gauges to wells MW-2 and
MW-4 to assess for vacuum influence from the MMPE event. Magnehelic gage readings indicated
no negative pressures in monitoring wells MW-2 or MW-4 during the MMPE event; however, the
groundwater decreased by 0.20 feet in monitoring well MW-2 and 0.11 feet in monitoring well
MW-4.

Calculations for MMPE emissions and total gallons recovered of wastewater for the MMPE
event are provided in the Mobile Multi-Phase Extraction Report document provided by
Advanced, which is provided in Appendix A. The waste disposal manifest from the MMPE is
also included in Appendix A. Field notes from the MMPE event are provided in Appendix B.

5.0 GROUNDWATER CHARACTERIZATION
5.1 Water Supply Wells
Eleven water supply wells have been previously identified within 1,000 feet from the site.
Figure 2 depicts the location of the water supply wells on an aerial overlay. Table 2 summarizes
water supply well information. On June 6, 2019, ATC collected samples from water supply wells
located at 2425 US Highway 21 (site/WSW-1), 2508 US Highway 21 (WSW-2), 1708/1712
Hamptonville Road (WSW-5), 1717 Hamptonville Road (WSW-6), 2405 US Highway 21 (WSW-
7) and 2401 US Highway 21 (WSW-9). Wells located at 1704 Hamptonville Road (WSW-3) and
2345 US Highway 21 (WSW-10) could not be sampled due to occupant absence.

Each water supply well sample was collected from outdoor spigots after the spigot 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. Sample analytical results from
supply well sampling detected the following:

 A concentration of toluene (0.87 µg/L) was detected in water supply well WSW-2 below
2L Standards;
 A concentration of 1,1-dichloroethane (0.31 J µg/L) was detected in water supply well
WSW-7 below 2L Standards
 Concentrations of MTBE (0.13 J µg/L), acetone (55.1 µg/L), chloromethane (0.33 J
µg/L), chloroethane (0.34 J µg/L) 1,1-dichloroethane (0.28 J µg/L) and methyl ethyl
ketone (17.1 µg/L) were detected in well WSW-9 below 2L Standards;
 No compounds were detected in water supply wells WSW-1, WSW-5, or WSW-6; and
 The NCDEQ performed a HRE for each well with detected compounds. Each HRE
indicated no restrictions on the use of the water at this time. HRE documentation is
provided in Appendix C.

Table 3 summarizes current water-supply well analytical results, and Table 4 summarizes
historical water supply well analytical results. Field notes from the June 6, 2019, groundwater
monitoring event are presented in Appendix A.

Based on the sampling results of water supply wells WSW-2, WSW-7, and WSW-9, the NCDEQ
conducted Health Risk Evaluations (HRE), and submitted the results of the HREs dated July 2,
2019 to the owners of the properties with these water supply wells. Each of the HRE letters
stated “The detected contaminant(s) did not exceed the applicable water standard(s). Therefore,
no restriction on the use of this water are recommended at this time.” Copies of the HRE letters
are included in Appendix D.

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 groundwater monitoring activities. 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.

5.2 Groundwater Levels
On June 6, 2019, site wells were gauged for depth to water. LNAPL was not observed in the
monitoring well network. Figure 3 depicts a site map. Monitoring well construction details are
included in Table 5. An oil/water interface probe was used to measure the depth to groundwater
from the top of well casing (TOC) in each well. Depth to groundwater elevation data are

summarized in Table 1. Based on groundwater gauging data from the June 6, 2019, groundwater
monitoring event, groundwater is expected to flow to the east-northeast toward a tributary to
South Deep Creek and to the south-southeast toward a tributary of North Little Hunting Creek.
Historical data has generally shown groundwater flow towards the east, however, the 2017
groundwater monitoring event suggested flow toward the south-southeast. Since the site is
situated on a topographic ridge, groundwater flow directions may change with changes in
groundwater levels or precipitation. Figure 4 depicts a groundwater elevation contour map. Field
notes from the June 6, 2019, groundwater monitoring event are presented in Appendix A.

5.3 Groundwater Quality

On June 6, 2019, ATC collected groundwater samples from wells MW-1 through MW-6 and
recovery well RW-6. 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 North Carolina accredited SGS in Orlando,
Florida. 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 6. Note low dissolved oxygen concentrations in wells MW-1,
MW-3, and RW-1 indicate biological activity in the presence of petroleum constituents. Current and
historical groundwater analytical results are summarized in Table 7 and Table 8, 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 groundwater monitoring network.
 Monitoring wells MW-1, MW-3, and recovery well RW-1 contained concentrations of
benzene and 1,2-dibromoethane above the respective GCL. Monitoring well MW-1 and
recovery well RW-1 additionally contained concentrations of 1,2-dichloroethane above
GCLs. Additional compounds were detected in wells MW-1, MW-3, and recovery well
RW-1 at concentrations exceeding the 2L Standards.
 None of the detected compounds in wells MW-2, MW-5, or MW-6 exceeded 2L Standards.
 No petroleum compounds were detected in well MW-4.

Note that due to the apparent fluctuations in groundwater flow direction with time, monitoring well
MW-1 may be considered a downgradient monitoring well during well. Thus, the extent of
groundwater impact exceeding the 2L Standards and GCLs is not defined to the southeast. Water
supply wells WSW-7, WSW-9, and WSW-10 are located southeast of monitoring well MW-1.

Figures 5 depicts concentrations of concern for petroleum compounds that exceeded 2L
Standards and GCLs.

The QA and QC measures and conditions applicable to the water supply well monitoring, as
discussed in Section 4.1, also apply to the monitoring well sampling.

6.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed a GMR
documenting a May 6, 2019 through May 10, 2019 MMPE event, and the June 6, 2019
groundwater monitoring event for Williams Grocery, located at 2425 US Highway 21,
Hamptonville, Yadkin County, North Carolina. Three of the sampled water supply wells
contained one or more contaminants, with all concentrations less than the 2L Standards. LNAPL
was not observed in the groundwater monitoring network.

Based on the calculations from the MMPE event, it appears that the MMPE was effective in mass
removal of petroleum hydrocarbons. However, only slight reductions in dissolved phase
concentrations were realized and concentrations in the monitoring well network continue to exceed
GCLs. Evaluation of benzene concentrations in wells MW-1, MW-3, and RW-1 does not indicate a
decreasing trend, and it does not appear that MMPE and air sparging is an effective practice in
reducing dissolved phase concentrations in these wells. However, historically, concentrations in
downgradient monitoring well MW-5 have indicated decreasing concentrations that may be due in
part to the remedial actions.

Based on the remaining dissolved phase concentrations in the groundwater, ATC recommends
evaluation of chemical injection options to increase reduction of dissolved phase concentrations.

Event Dates: May 6 - May 10, 2019
Advanced Job # 05 - 1923

Advanced Personnel: Lee Heilig and Gary McDaniel

MMPE System: MMPE system rated 24”hg at 140 CFM
4’ discharge stack - 2” diameter
5,000 - gallon tanker
160 ft. piping 2.0” hose to 3 wells

Extraction Well: MW-1, MW-3 and RW-1, air sparge AS-1

/ Changed To
MW-1 20.34 25.49 20 96.0 hours
MW-3 20.92 21.39 20 96.0 hours
RW-1 20.90 21.31 20 96.0 hours

Description of Event:
The MMPE event ran from 11:30 May 6, through 11:30 May 10, 2019. The MMPE system was
active for 96.0 hours. During the event vacuum at the recovery pump ranged from 19.0 to 21.0
inches of mercury (hg) and stabilized at approximately 19.0 inches of mercury. Airflow rates
ranged from 3,500 to 4,000 feet per minute and stabilized at approximately 4,000 feet per
minute. Due to excessive water recovery, flow was reduced approximately 45 percent. System
temperature ranged from 122 – 144 degrees F and humidity ranged from 34 to 99 percent. Field
gauged volatile organic compounds (VOC’s) emissions decreased from 40,000 to 8,000 parts
per-million (PPM) throughout the event.

Groundwater / Product Mix Recovered:
During the event a total of 4,869 gallons of product/water mix were removed from the site and
properly disposed at a certified North Carolina disposal facility. No free product was observed
in the tanker. Total fluids recovered, was measured based on stick readings conducted during
and following the event. Based on 96.0 hours of operation and a total of 4,869 gallons recovered,
the average groundwater recovery rate was calculated to be approximately 50.72 gallons per
hour.

Events Results:
Based on mass-removal calculations 269.57 pounds or 43.82 gallons of VOC’s were removed as
vapor. Using Dwyer magnehelic gauges, vacuum influence (inches of water) was measured at
monitoring points MW-2 and MW-4. No measurable vacuum influence was identified at any
monitoring point. Maximum draw-down was identified in MW-2 and MW-4 at 0.20 and
0.11 feet respectively. Following the event, no free product was identified in any well.
