B. EXECUTIVE SUMMARY
The purpose of this report is to evaluate the current status of the groundwater quality at the former
Johnson’s Grocery site (Incident No. 30594). Terracon completed this report to summarize the
findings of assessment activities performed on May 14, 2020. The release incident is situated on
the property located at 5870 NC Highway 268 in Dobson, Surry County, North Carolina in an area
developed mostly as agricultural land with rural residences. The site is currently occupied by an
automotive repair facility and used car sales lot. According to historical assessment information,
three on-site USTs at the former Johnson’s Grocery were removed in June 2005. Soil sampling
conducted during closure activities indicated a petroleum release originated from the former UST
system. The release was attributed to product piping located near the northern end of the former
UST basin. Additional excavation activities were completed at the site and reportedly 702.15 tons of
petroleum impacted soil were removed from the site.

Terracon mobilized to the site on May 14, 2020 to conduct groundwater sampling activities. Initially,
Terracon gauged the groundwater elevations in monitoring wells MW-1 through MW-4, MW-7 and
MW-8. Depth to groundwater in the monitoring wells ranged from approximately 15.82 feet below
top of casing (btoc) in well MW-3 to 27.45 feet btoc in well MW-7. Approximately 0.01 feet of light
non-aqueous phase liquid (LNAPL) was measured in well MW-1 and sheens were noted in several
other on-site wells. Based on top of casing elevations, groundwater flow is to the northwest. Prior to
sampling, the wells were purged a minimum of three well volumes. ORC inserts were removed from
wells MW-2, MW-4, MW-7 and MW-8 and replaced with new inserts after the wells were sampled.
The samples, along with chain-of-custody documentation, were delivered to Pace Analytical
Services, Inc. in Huntersville, North Carolina for analysis of volatile organic compounds (VOCs) by
Standard Method 6200B, including MTBE, EDB and IPE.

Benzene was detected at concentrations above its Gross Contamination Level (GCL) in wells MW-1
(22,500 micrograms per liter [µg/L]) and MW-8 (8,360 µg/L). Methyl tert-butyl ether (MTBE) [31,700
µg/L] and 1,2-dibromoethane (EDB) [102J µg/L] were also detected in well MW-1 at concentrations
that exceed the respective GCLs.
Johnson’s Grocery Store Dobson, North Carolina Terracon Project No. 71149156A Incident No. 30594 June 25, 2020

Responsive ■ Resourceful ■ Reliable 3
The following constituents were detected in one or more on-site monitoring wells at concentrations
that exceed the 15A NCAC 2L groundwater standards; benzene, 1,2-dichloroethane, diisopropyl
ether (IPE), ethylbenzene, EDB, MTBE, isopropylbenzene, naphthalene, toluene, 1,2,4-
trimethylbenznene and total xylenes. Various petroleum constituents were detected in the on-site
wells above the laboratory method detection limits (MDLs) but below the 2L groundwater standards.
Detected concentrations of benzene and toluene were also compared to the respective 15A NCAC
2B surface water standards since a drainage feature is located along the northern property
boundary. Benzene and toluene exceed the respective 2B surface water standards for Class C
waters in wells MW-1, MW-2, MW-7 and MW-8.
Based on information obtained during the completion of our assessment activities, Terracon
provides the following conclusions and findings.
LNAPL was detected in well MW-1 at less than a thickness of 0.01 feet but the water level in the
well during this sampling event was above the screened interval. Sheens were observed in
several other wells at the site.
Benzene was detected at concentrations that exceed its GCL in wells MW-1 and MW-8. MTBE
and EDB were also detected above the respective GCLs in well MW-1.
Benzene, 1,2-dichloroethane, IPE, ethylbenzene, EDB, isopropylbenzene, MTBE, naphthalene,
toluene, 1,2,4-trimethylbenznene and total xylenes were detected in one or more monitoring
wells above the respective 2L standards.
Benzene and toluene were detected in wells MW-1, MW-2, MW-7 and MW-8 above the
respective 2B standards.
Various petroleum constituents were also detected in the on-site wells at concentrations below
the 2L groundwater standards.
Based on water level measurements, groundwater flow is towards the northwest.
Five private water-supply wells are reportedly located within 1,000 feet of the source area that
are currently utilized as sources of potable water. Municipal water is not available to the site or
the immediately surrounding properties. Previous sampling events have shown no contamination
within the supply wells.
Constituent concentrations trends are generally decreasing at the site.
Based on the data presented in this monitoring report, Terracon recommends the following activities
be completed at the site.
Terracon recommends replacing the O-sox inserts in the on-site wells while gauging LNAPL in
well MW-1 in August 2020
Based on the analytical results, Terracon also recommends conducting surface water sampling
on the on-site tributary of Little Beaver Creek in August 2020.

Groundwater monitoring wells and the on-site water supply well should be sampled semi-
annually to evaluate the status of impact by petroleum constituents.
Terracon believes that the use of injectants (potassium persulfate activated by ferric iron) is a
viable approach based on the results of the test injection previously conducted at well MW-3.
Terracon recommends contacting remedial vendors to evaluate the data and discuss an
injection event in wells MW-1, MW-7 and MW-8.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate the current status of the groundwater quality at the former
Johnson’s Grocery site. Terracon completed this report to summarize the findings of assessment
activities performed on May 14, 2020 at the former Johnson’s Grocery located at 5870 NC Highway
268 in Dobson, Surry County, North Carolina (Figure 1). This Subsequent Monitoring Report was
prepared for the site in response to a request by the Incident Manager, Mr. Herb Berger with the
NCDEQ Division of Waste Management, Trust Fund Branch.

The subsequent monitoring report was prepared in general accordance with 15A NCAC 2L .0115
regulations and the NCDEQ Underground Storage Tank (UST) Section Guidelines for Assessment
and Corrective Action for UST Releases, dated July 15, 2008, revised December 2013, under the
supervision of Mr. Christopher L. Corbitt, a North Carolina registered licensed geologist (North
Carolina License No. 1015).

C.1 Site Setting

The Johnson’s Grocery site located at 5870 NC Highway 268 in Dobson, North Carolina is
comprised of 2.919 acres. The property contains an approximate 8,550 square foot commercial
building occupied by The Car & Truck Hut an automotive maintenance shop). A stand-alone garage
structure is also located on the site and is utilized by the automotive repair shop and used car sales.
The site is depicted in Figure 2.

The site is bound to the north by a chicken farm, wooded acreage, and a surface water drainage
feature. NC Highway 268 bounds the site to the south. A large area of farm land is located farther to
the south, across NC Highway 268. Properties to the east and west, along NC Highway 268, are
developed as rural residential.

C.2 Release Summary

A petroleum release was discovered following the removal of the former on-site UST systems in
August 2005. Soil sampling conducted during closure activities indicated the petroleum release was
attributed to product piping located near the northern end of the former UST basin. A chronological
summary of the UST removal activities and subsequent groundwater assessment activities at the
Johnson’s Grocery Store Dobson, North Carolina Terracon Project No. 71149156A Incident No. 30594 June 25, 2020

site is discussed in the following section of the report.

C.3 Previous Investigations

In June 2005, three former on-site USTs were reportedly removed from the site. Soil sampling
conducted during closure activities indicated a petroleum release had occurred from the former UST
system. The release was attributed to product piping located near the northern end of the UST
basin. Additional excavation activities were completed at the site, removing 702.15 tons of
petroleum-impacted soil. Following over excavation activities, four soil samples were collected from
the bottom of the excavation, the risk-based analytical results indicated the presence of various
petroleum constituents at concentrations that exceeded the respective Soil-to-Water Maximum Soil
Contaminant Concentrations (MSCCs). Benzene, naphthalene, n-propylbenzene, 1,3,5-
trimethylbenzene, C5-C8 aliphatics, and C9-C22 aromatics were also detected at concentrations
exceeding the respective Residential MSCCs.

A Phase II LSA Report was completed for the site by GeoScience & Technology, P.A. (GeoScience)
in February 2006 to further assess the on-site petroleum release. GeoScience personnel visited the
site to install two soil borings/monitoring wells (B1/MW-1 and B2/MW-2) in previously identified
source areas from August 2005. Soil samples collected from the two borings identified multiple
petroleum (gasoline range) constituents. GeoScience personnel returned to the site in January 2006
to install three additional monitoring wells (MW-3, MW-4 and MW-5). The on-site wells were
sampled in January 2006 with the exception of well MW-1 which contained approximately 2.74 feet
of product. Sampling of the wells indicated multiple petroleum constituents were detected in the
groundwater above the 2L groundwater standards.

Terracon mobilized to the site on July 24, 2014 to conduct groundwater sampling activities.
Terracon was unable to locate well MW-5 with a metal detector due to dense vegetation to the west
of the vacant grocery store building. During the sampling event, depth to groundwater in the
monitoring wells ranged from approximately 17.9 to 24.4 feet bgs. Groundwater flow was
determined to be towards the northwest. Terracon also sampled two nearby water supply wells
(WSW-1 and WSW-3) to evaluate potential impacts to off-site receptors. Terracon attempted to
sample wells WSW-2 and WSW-4 but did not receive a response from the well owners. Laboratory
results indicated various petroleum constituents were detected in the monitoring wells at the site.
The following constituents were detected at concentrations above the respective 2L groundwater
standards: benzene in wells MW-2 (67.4 µg/L) and MW-4 (46.4 µg/L); naphthalene in wells MW-2
(19.1 µg/L) and MW-4 (27.8 µg/L); n-propylbenzene in well MW-4 (115 µg/L); and 1,2,4-
trimethylbenzene in well MW-4 (621 µg/L). No petroleum constituents were detected in the two
water supply wells sampled during this event.

Terracon personnel returned to the site on January 12, 2015 to conduct a 96-hour Mobile Multi-
Phase Extraction (MMPE) event at monitoring wells MW-1 and MW-5 which contained the highest
levels of petroleum constituents or LNAPL based on recent and historic groundwater sampling
Johnson’s Grocery Store Dobson, North Carolina Terracon Project No. 71149156A Incident No. 30594 June 25, 2020

events conducted on the site. Terracon was unable to locate well MW-5 and subsequently MMPE
activities were only conducted utilizing well MW-1. The MMPE event was conducted by ZAVA
Industrial Inc. from January 12, 2015 to January 16, 2015. According to ZAVA’s field report dated
January 16, 2015, a total of 1,784 gallons of water was recovered from the well and mass balance
calculations indicated total VOC emissions removed from the well equated to 24.52 gallons. In
addition to the MMPE event, two soil borings (GP-6 and GP-7) were advanced by Probe
Technology, Inc. to approximate depths of 30 feet bgs. Soils collected from the borings were
screened for organic vapors using a photo-ionization detector (PID). Soil Samples GP-6(20-25) and
GP-7(20-25) were submitted to Pace Analytical in Huntersville, North Carolina for analysis of risk-
based parameters. According to the laboratory analytical report, benzene was detected in sample
GP-7(20-25) at 9.6 micrograms per kilogram (µg/kg) which exceeded the Soil-to-Water MSCC of 5.6
µg/kg. Additional analytes were detected at concentrations below the respective Soil-to-Water
MSCCs. The two borings (GP-6 and GP-7) were converted to monitoring wells to assess the lateral
extent of petroleum constituents in the groundwater.

In August 18, 2015, Terracon attempted to sample the seven on-site monitoring wells. Terracon was
unable to locate wells MW-5 and MW-6 with a metal detector due to dense vegetation along the
northern property boundary. Approximately 3 feet of LNAPL was measured in well MW-1. Benzene
was detected in well MW-7 above the established GCL. Various other petroleum constituents were
detected in wells MW-2, MW-4 and MW-7 above the respective 2L groundwater standards.

Terracon mobilized to the site in March 2018 to sample wells MW-1, MW-2 through MW-4 and MW-
7. Approximately 1.58 feet of LNAPL was observed in well MW-1. Terracon hand bailed
approximately 0.5 gallons of LNAPL into an on-site drum and installed a NewPig Absorbent sock
into the well after hand bailing was completed. Based on the analytical results, multiple constituents
were detected above the established 2L standards in wells MW-2, MW-4 and MW-7; however,
benzene concentrations in well MW-7 decreased from 9,300 µg/L (2015) to 3,330 µg/L during the
March 2018 sampling event.

In October 2018, Terracon collected groundwater samples from the on-site monitoring wells and
collected a surface water sample (SW-01) from the unnamed tributary that borders the site to the
north and east. Approximately 0.04 feet of LNAPL was measured in well MW-1; therefore, a water
sample was not collected. Multiple target constituents were detected above the established 2L
standards in wells MW-2, MW-4 and MW-7. Benzene was also detected above the established 15A
NCAC 2B surface water standards in sample SW-01.

In February 2019, Terracon mobilized to the site to provide oversight and document an injection pilot
study conducted at the site. Terracon observed the installation of four injection points using direct
push technology (DPT) to the target injection depth of 35 ft bgs. The solution used at the site was
designed to destroy organic compounds dissolved in the groundwater and adsorbed to the aquifer
materials. The solution combined the use of sodium persulfate, potassium persulfate and ferric
oxide to produce long-term oxidation within the subsurface and provide the appropriate components
for a longer lasting biological attenuation process following the initial oxidation event. A total of 2,700

gallons of solution was injected into the subsurface. Terracon also installed well MW-8 down-
gradient of the source area and up-gradient of well MW-7 to further delineate the contaminant
plume.

In September 2019, Terracon mobilized to collect groundwater samples from six of the on-site
monitoring wells. Prior to sample collection, Terracon gauged the groundwater levels in monitoring
wells MW-1 through MW-4, MW-7 and MW-8. Depth to groundwater in the monitoring wells ranged
from approximately 16.33 feet (MW-3) below ground surface (bgs) to 25.57 feet (MW-7) bgs.
Approximately 0.01 feet of LNAPL was measured in well MW-1. Benzene was detected at a
concentration above the established GCL in wells MW-1, MW-7 and MW-8. MTBE and EDB were
also detected in well MW-1 at concentrations that exceed the GCLs. The following constituents were
detected at concentrations that exceed the 2L standards in various on-site wells: 1,2-dichloroethane,
IPE, ethylbenzene, EDB, isopropylbenzene, MTBE, naphthalene, toluene, 1,2,4-trimethylbenznene
and total xylenes. Various petroleum constituents were detected in wells MW-2 and MW-4 below the
2L groundwater standards. Target analytes were not detected above the MDLs in monitoring well
MW-3.

In January 2020, Terracon and Advanced Environmental Services (AES) conducted a 96-hour
MMPE event at monitoring well MW-1. According to the AES field report dated February 6, 2020, a
total of 2,357 gallons of a product/water mixture was recovered from the well and mass balance
calculations indicated total VOC emissions removed from the well equated to 3.77 gallons.

C.4 Water Supply Wells

The nearest water-supply well (WSW-1), located on the site within 100 feet of the release area, is
currently utilized by the on-site auto repair shop. Well WSW-3 is located approximately 850 feet
west and down-gradient of the release area. The well is utilized as a source of potable water by an
on-site residence. Well WSW-2 is located on an up-gradient residential property to the east of the
release area and up-gradient well WSW-4 is associated with a large farm located to the south
across NC Highway 268. Well WSW-5 was observed on the northwestern adjacent property,
currently developed as a chicken farm, during our site visit in March 2018. Results of the water-
supply well inventory are presented in Table 1 and well locations are depicted on Figure 6.

C.5 Surface Water

According to the USGS topographic map, the site is situated on the northwestern flank of a
northwest-southeast trending topographic ridge system that generally parallels NC Highway 268.
The site is located within the drainage basin for an unnamed tributary of Little Beaver Creek, which
is located along the northern and eastern property boundaries. According to the NC Surface Water
Classifications online database, Little Beaver Creek is classified as a Class C surface water feature.
Surface waters are depicted on Figure 1.

C.6 Land Use Information

The site is bound to the north by a mixture of farm land and wooded acreage. NC Highway 268
bounds the site to the south, with a large farm located farther south. Properties to the east and west
along NC Highway 268 are developed as residential.
D. ASSESSMENT INFORMATION

D.1 Site Geology and Hydrogeology

The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.

Copeland Quadrangle, North Carolina, USGS 7.5-minute series topographic map, dated 1994
(Figure 1).
Geologic Map of North Carolina, dated 1985.
The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by
J. Wright Horton, Jr., and Victor A. Zullo, The University of Tennessee Press, dated 1991.
Soil Survey of Surry County, North Carolina, US Department of Agriculture, Natural Resources
Conservation Service, Web Soil Survey via the Internet, http://websoilsurvey.nrcs.usda.gov/app/ .

The site is located within the Sauratown Mountains Anticlinorium of the Piedmont Physiographic
Province. The Piedmont Province generally consists of low to medium elevation, rounded hills and
long rolling northeast to southwest trending ridges with incised creeks and river channels.
Underlying rock in the site area is described as biotite gneiss, amphibolite and kyanite schist.

In-place chemical and physical weathering of parent rocks typically form residual soils in the
Piedmont region. Weathering is facilitated by the presence of fractures, joints, and less resistant
minerals in the rock. In areas not altered by erosion, alluvial deposition or the activities of man, the
typical residual soil profile consists of clay-rich unconsolidated materials at the surface, transitioning
to sandy silts and silty sands at depth. Typically, the boundary between soil and rock is not sharply
defined. This transitional zone is termed “partially weathered rock” or saprolite. Information
obtained from the Soil Survey for Surry County, depicts soils on the site as Fairview sandy clay loam
(FeC2).

In the Piedmont, groundwater generally occurs in pore spaces within soils and in the structural
features present in the underlying rock (i.e. joints, fractures, and faults). Recharge to the water table
is primarily by precipitation infiltrating the surficial soils and percolating downward under the
influence of gravity to the water table (vadose zone). Typically, the water table is not a level surface,
but a subdued reflection of the land surface. The depth to the water table is not consistent and is
Johnson’s Grocery Store Dobson, North Carolina Terracon Project No. 71149156A Incident No. 30594 June 25, 2020

Responsive ■ Resourceful ■ Reliable 9
dependent upon several factors that include the amount of rainfall, permeability of the soil, the
extent of fracturing in the underlying rock and the influences of groundwater pumping. Groundwater
typically flows in directions parallel to the ground surface and under the influence of gravity, migrates
to discharge points such as surface water features, the toes of slopes or natural springs.

Fluctuations in the depth of the water table can be expected depending on variations in precipitation,
surface water run-off and other factors not evident at the time of our subsurface exploration.
Normally, the highest levels of the water table occur in late winter and spring and the lowest levels
occur in the late summer and fall. Groundwater has been interpreted to flow to the northwest from
the site.

D.2 Sampling Activities

D.2.1 LNAPL Evaluation

Approximately 0.01 feet of LNAPL was measured in monitoring well MW-1 on May 14, 2020. Due to
the decrease in LNAPL thickness, Terracon collected a groundwater sample from well MW-1. The
absorbent sock was not replaced during this sampling event to allow monitoring of the LNAPL
thickness during the next sampling event. During the May 2020 sampling event, the screened
interval in well MW-1 was submerged, which could attribute to a decrease in LNAPL during this
sampling event. It could also be attributed to movement of the contaminant plume towards down-
gradient areas.

D.2.2 Groundwater Sampling Activities

Terracon mobilized to the site on May 14, 2020 to conduct groundwater sampling activities. Initially,
Terracon gauged the groundwater elevations in monitoring wells MW-1 through MW-4, MW-7 and
MW-8. Depth to groundwater in the monitoring wells ranged from approximately 15.82 feet btoc in
well MW-3 to 27.45 feet btoc in well MW-7. Approximately 0.01 feet of LNAPL was measured in well
MW-1 and sheens were noted in several other on-site wells. Based on top of casing elevations,
groundwater flow is to the northwest. Prior to sampling, the wells were purged a minimum of three
well volumes. ORC inserts were removed from wells MW-2, MW-4, MW-7 and MW-8 and replaced
with new inserts after the wells were sampled. The approximate locations of the wells are shown on
the Site Plan (Figure 2). A groundwater elevation map depicting groundwater flow contours and
direction is shown on Figure 3. Current and historical groundwater elevation measurements are
provided in Table 3.
The groundwater samples and an equipment blank were placed in laboratory-supplied glassware,
labeled and stored in an ice-packed cooler. The samples, along with chain-of-custody
documentation, were delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina for
analysis of VOCs by Standard Method 6200B, including MTBE, EDB and IPE.

D.2.3 Analytical Results
Based on the laboratory analytical results, various petroleum constituents were identified at
concentrations above the laboratory reporting limits in monitoring wells MW-1 through MW-4, MW-7
and MW-8.

Benzene was detected at concentrations above its GCL in wells MW-1 (22,500 µg/L) and MW-8
(8,360 µg/L). MTBE (31,700 µg/L) and EDB (102J µg/L) were also detected in well MW-1 at
concentrations that exceed the respective GCLs.

The following constituents were detected in one or more on-site monitoring wells at concentrations
that exceed the 15A NCAC 2L groundwater standards; benzene, 1,2-dichloroethane, diisopropyl
ether (IPE), ethylbenzene, EDB, MTBE, isopropylbenzene, naphthalene, toluene, 1,2,4-
trimethylbenznene and total xylenes. Various petroleum constituents were detected in the on-site
wells above the laboratory MDLs but below the 2L groundwater standards. Detected concentrations
of benzene and toluene were also compared to the respective 15A NCAC 2B surface water
standards since a drainage feature is located along the northern property boundary. Benzene and
toluene exceed the respective 2B surface water standards for Class C waters in wells MW-1, MW-2,
MW-7 and MW-8.

The groundwater analytical results from the monitoring wells are summarized in Table 2. The
analytical results are also depicted on Figure 4. A benzene isoconcentration map is provided as
Figure 5. Copies of the laboratory analytical reports are provided in Appendix A.
E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of our assessment activities, Terracon
provides the following conclusions and findings.
LNAPL was detected in well MW-1 at less than a thickness of 0.01 feet but the water level in the
well during this sampling event was above the screened interval. Sheens were observed in
several other wells at the site.
Benzene was detected at concentrations that exceed its GCL in wells MW-1 and MW-8. MTBE
and EDB were also detected above the respective GCLs in well MW-1.
Benzene, 1,2-dichloroethane, IPE, ethylbenzene, EDB, isopropylbenzene, MTBE, naphthalene,
toluene, 1,2,4-trimethylbenznene and total xylenes were detected in one or more monitoring
wells above the respective 2L standards.
Benzene and toluene were detected in wells MW-1, MW-2, MW-7 and MW-8 above the
respective 2B standards.

Various petroleum constituents were also detected in the on-site wells at concentrations below
the 2L groundwater standards.
Based on water level measurements, groundwater flow is towards the northwest.
Five private water-supply wells are reportedly located within 1,000 feet of the source area that
are currently utilized as sources of potable water. Municipal water is not available to the site or
the immediately surrounding properties. Previous sampling events have shown no contamination
within the supply wells.
Constituent concentrations trends are generally decreasing at the site.
Based on the data presented in this monitoring report, Terracon recommends the following activities
be completed at the site.
Terracon recommends replacing the O-sox inserts in the on-site wells while gauging LNAPL in
well MW-1 in August 2020
Based on the analytical results, Terracon also recommends conducting surface water sampling
on the on-site tributary of Little Beaver Creek in August 2020.
Groundwater monitoring wells and the on-site water supply well should be sampled semi-
annually to evaluate the status of impact by petroleum constituents.
Terracon believes that the use of injectants (potassium persulfate activated by ferric iron) is a
viable approach based on the results of the test injection previously conducted at well MW-3.
Terracon recommends contacting remedial vendors to evaluate the data and discuss an
injection event in wells MW-1, MW-7 and MW-8.
