B. EXECUTIVE SUMMARY
The Johnson’s Grocery site located at 5870 NC Highway 268 in Dobson, North Carolina (Figure 1) is
comprised of approximately 2.919 acres. The property contains an approximate 8,550 square foot
commercial building composed of a vacant former grocery store and an automobile maintenance
center, a stand-alone garage structure is also located on the site and utilized by the automobile
repair center. Three former on-site USTs were reportedly removed in June 2005. Soil sampling
conducted during closure activities indicated a petroleum release from the former UST system. The
release was attributed to product piping located over the northern end of the former USTs. Additional
excavation activities were completed at the site and a total of 702.15 tons of petroleum impacted
soils were removed from the site.

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 in August 2005. Soil samples collected during well installation identified multiple volatile
organic constituents consistent with a gasoline release. GeoScience personnel returned to the site in
January 2006 to install an additional three monitoring wells (MW-3, MW-4, and MW-5). On-site wells
were sampled in January 2006 with the exception of MW-1 which was discovered to contain free
product. The groundwater sampling conducted indicated multiple petroleum constituents above their
respective 15A NCAC 2L groundwater standards.

At the direction of the NCDENR, Terracon mobilized to the site on July 24, 2014 to sample the five
on-site monitoring wells (MW-1 through MW-5) and two nearby water supply wells (WSW-1 and
WSW-3). Terracon was unable to locate well MW-5 with a metal detector due to dense vegetation to
the west of the on-site building. Approximately 4- inches of free product were observed in well MW-1.
Depth to groundwater in the monitoring wells ranged from approximately 17.9 to 24.4 feet below
ground surface (bgs). Groundwater flow was determined to be toward the northwest.

Following well development, groundwater samples were collected from each well, placed in
laboratory provided containers and delivered to Pace Analytical Services, Inc., in Huntersville, North

Carolina for analysis of volatile organic compounds (VOCs) by Standard Method 6200, including
methyl tert-butyl ether (MTBE), ethylene dibromide (EDB), and diisopropyl ether (IPE).
Laboratory results indicated various petroleum constituents were detected in the monitoring wells at
the site. The following constituents were detected at concentrations above their respective 15A
NCAC 2L groundwater standards including: 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); 1,2,4-trimethylbenzene in well MW-4 (621 µg/L). No petroleum constituents were
detected in the two off-site water supply wells sampled during this event.
Based on information obtained during the completion of our assessment activities, Terracon provides
the following conclusions and findings.

Benzene and naphthalene have been detected at concentrations that exceed their 15A NCAC 2L
groundwater standards in wells MW-2 (benzene and naphthalene only) and MW-4. Well MW-4 also
had concentrations of n-propylbenzene and 1, 2, 4-trimethylbenzene above their respective 2L
standards. Various other petroleum constituents were also detected in the on-site wells but at
concentrations below the 15A NCAC 2L groundwater standards.
The initial sampling event (2005) of well MW-1 which is immediately down-gradient of the former
tank basin identified benzene at a concentration that exceeded its Gross Contamination Level
(GCL). More recent sampling events identified free product in well MW-1. The detection of free
product in the well could be due to the contaminant plume migrating from the source area.
Petroleum constituent concentrations have generally decreased in monitoring well MW-2 which is
located within the former tank basin and perceived source area. The benzene concentration in
cross-gradient well MW-4 has increased, while concentrations of ethylbenzene, toluene and xylenes
have decreased. These results from well MW-4 could be reflective of the heterogeneity of the
contaminant plume.
None of the detected petroleum constituents exceeded the GCLs.
Approximately 4 inches of free product was measured in well MW-1.
Groundwater flow was determined to be toward the northwest.
Four private water-supply wells are located within 1,000 feet of the source area, which are currently
utilized for potable water. Municipal water is not available to the site or the immediately surrounding
properties.
No petroleum constituents were detected in the on-site water supply well (WSW-1) or the off-site
water supply wells (WSW-3) sampled during this event.

activities performed on July 24, 2014 at the former Johnson’s Grocery located at 5870 NC Highway
268 in Dobson, Surry County, North Carolina (Figure 1). This Federal/State-Lead Monitoring report
was prepared for the site in response to a request by the Incident Manager, Mr. Herb Berger with the
NCDENR Division of Waste Management, State Lead Program.

The Federal/State-Lead Monitoring Report was prepared in general accordance with 15A NCAC 2L
.0115 regulations and the NCDENR 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 approximately 2.919 acres. The property contains an approximate 8,550 square foot commercial
building, containing a vacant former grocery store and an automobile maintenance center, a stand-
alone garage structure is also located on the site and utilized by the automobile repair center. The
site is depicted in Figure 2.

The site is bound to the north by a mixture of cultivated agricultural lands and wooded acreage. NC
Highway 268 bounds the site to the south. A large expanse 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 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 a petroleum release the
former UST system, the release was attributed to product piping located over the northern end of the
former USTs. A chronological summary of the UST removal activities and subsequent groundwater
assessment activities at the 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 from the former UST system; the
release was attributed to product piping located over the northern end of the USTs. Additional
excavation activities were completed at the site and a total of 702.15 tons of petroleum-impacted soil
were removed from the site. Following over excavation activities four soil samples were collected
from the bottom of the excavation, the analytical results of these samples indicated the presence of
several petroleum constituents at concentrations that exceeded their respective Soil to Groundwater
Maximum Soil Contaminant Concentrations (MSCCs). Benzene, naphthalene, n-propylbenzene,
1,3,5-trimethylbenzene, C5-C8 aliphatics, and C9-C22 aromatics were detected at concentrations
exceeding their 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 in August 2005. Soil samples collected during well installation identified multiple volatile
organic constituents consistent with a gasoline release. GeoScience personnel returned to the site in
January 2006 to install an additional three monitoring wells (MW-3, MW-4, and MW-5). On-site wells
were sampled in January 2006 with the exception of well MW-1 which was discovered to contain free
product. The LSA indicated approximately 2.74 feet of product in monitoring well MW-1. The
groundwater sampling conducted indicated multiple petroleum constituents above their respective
15A NCAC 2L groundwater standards.

C.4 Water Supply Wells
Terracon confirmed the presence of four water-supply wells within 1,000 feet of the UST basin
(source area) during our site visit. 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 center. 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. Terracon was unable to access wells WSW-2 and
WSW-4 due to a lack of response from the well owners and because the homeowners were not
available at the time of our site visit. Well WSW-2 is located on an up-gradient residential property to
the east of the release area and well WSW-4 is associated with a large farm located south and up-
gradient of the release area, across NC Highway 268. Results of the water-supply well inventory are
presented in Table 1 and well locations are depicted on Figure 7.

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. Surface waters are depicted on Figure
1.

C.6 Land Use Information
The site is bound to the north by a mixture of cultivated agricultural land and wooded acreage. NC
Highway 268 bounds the site to the south, with a large farm located further south. Properties to the
east and west, along NC Highway 268, are developed as residential.

D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.

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 minor ultramafic and granitic rock.

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 Web 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
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. Based on an interpreted groundwater flow direction, groundwater
is expected to flow to the northwest from the site.

D.2.2 Groundwater Sampling Activities
Terracon mobilized to the site on July 24, 2014 to conduct groundwater sampling as requested by
the NCDENR. Prior to sample collection, Terracon gauged the groundwater elevations in monitoring
wells MW-1 through MW-4. The approximate locations of the wells are shown on the Site Plan
(Figure 2). Terracon was unable to locate well MW-5 with a metal detector due to dense vegetation
to the west of the on-site structure. Prior to sampling, the wells were purged a minimum of three
well volumes. The wells were allowed to recharge a minimum of 90 percent of the original well
volume before samples were collected for analysis. During this sampling event, depth to
groundwater in the monitoring wells ranged from approximately 17.9 to 24.4 feet below ground
surface (bgs). Groundwater flow was determined to be toward the northwest. A groundwater
elevation map depicting groundwater flow contours and direction if shown on Figure 3. Current and
historical groundwater elevation measurements are provided in Table 3.

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. Water samples were obtained from the water supply wells
by allowing water to flow from a spigot for approximately 15 minutes prior to collecting the sample to
retrieve a fresh sample from the well. Flow from the spigot was reduced when the sample was
collected. If a filter system was installed at a residence, sampling was conducted prior to water
passing through the filter.

The groundwater samples 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 volatile organic compounds
(VOCs) by Standard Method 6200B, including MTBE, EDB and IPE, and lead by EPA Method 6010.

D.2.3 Analytical Results
Based on the laboratory analytical report, various petroleum constituents were identified at
concentrations above the laboratory reporting limits in monitoring wells MW-2 and MW-4.

Benzene was detected at concentrations above its 15A NCAC 2L groundwater standard (1.0 µg/L) in
wells MW-2 (67.4 µg/L) and MW-4 (46.4 µg/L).

Naphthalene was detected at concentrations above its 15A NCAC 2L groundwater standard (6 µg/L)
in wells MW-2 (19.1 µg/L) and MW-4 (27.8 µg/L).

n-Propylbenzene (115 µg/L) and 1,2,4-trimethylbenzene (621 µg/L) were detected at concentrations
above their respective 15A NCAC 2L groundwater standards (70 µg/L and 400 µg/L, respectively) in
well MW-4.

No analytes were detected above the reporting limits in monitoring well MW-3.

E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of our assessment activities, Terracon provides
the following conclusions and findings.

Benzene and naphthalene have been detected at concentrations that exceed their 15A NCAC 2L
groundwater standards in two on-site wells (MW-2 and MW-4). Well MW-4 also had concentrations
of n-propylbenzene and 1, 2, 4-trimethylbenzene above their respective 2L standards. Various other
petroleum constituents were also detected in the on-site wells but at concentrations below their
respective 15A NCAC 2L groundwater standards.
The initial sampling event (2005) of well MW-1 which is immediately down-gradient of the former
tank basin identified benzene at a concentration that exceeded its Gross Contamination Level
(GCL). More recent sampling events identified free product in well MW-1. The detection of free
product in the well could be due to the contaminant plume migrating from the source area.
Petroleum constituent concentrations have generally decreased in monitoring well MW-2 which is
located within the former tank basin and perceived source area. The benzene concentration in
cross-gradient well MW-4 has increased, while concentrations of ethylbenzene, toluene and xylenes
have decreased. These results from well MW-4 could be reflective of the heterogeneity of the
contaminant plume.
None of the detected petroleum constituents exceeded the GCLs.
Approximately 4 inches of free product was measured in well MW-1.
Groundwater flow was determined to be toward the northwest.
Four private water-supply wells are located within 1,000 feet of the source area, which are currently
utilized for potable water. Municipal water is not available to the site or the immediately surrounding
properties.
No petroleum constituents were detected in the on-site water supply well (WSW-1) or the off-site
water supply wells (WSW-3) sampled during this event.

Based on the data presented in this Federal/State-Lead Monitoring report, Terracon recommends the
following activities be completed at the site.

Terracon proposes conducting a 96- hour Mobile Multiphase Extraction (MMPE) event utilizing wells
MW-1 and MW-5 ( based on historical benzene analytical results above the GCL) to remove free
product and petroleum impacted groundwater.
Vegetation should be cleared from the western side of the on-site structures and so that well MW-5
can be located and sampled.
Installation of an additional 3 Type II groundwater monitoring wells in down-gradient locations to
further define the horizontal extent of contamination.
Groundwater monitoring wells and selected off-site water supply wells should be sampled semi-
annually to evaluate the status of impact by petroleum constituents.
