B. EXECUTIVE SUMMARY
The purpose of this report is to summarize the groundwater sampling event conducted in March
2020. Terracon mobilized to the site on March 5, 2020 to collect groundwater samples from
monitoring wells MW-1, MW-4, MW-5 and MW-11 and water supply wells WSW-1 and WSW-2
for laboratory analysis. Prior to sampling, Terracon gauged the groundwater levels in the
monitoring wells. During this sampling event, depth to groundwater in the monitoring wells ranged
from approximately 1.56 feet (well MW-1) below ground surface (bgs) to 15.25 feet bgs in well
MW-4. Based on groundwater level measurements, the estimated groundwater flow direction is
to the east/northeast. Terracon was unable to sample the water supply wells due to no responses
to our water supply well letters and no one at home to grant us access. The water samples were
submitted for laboratory analysis of volatile organic compounds (VOCs) by Standard Method
6200, including MTBE, IPE and EDB.
According to the laboratory analytical report, 1,2-dichloroethane (957 micrograms per liter [µg/L])
was detected in monitoring well MW-5 at a concentration above its Gross Contamination Level
(GCL). Benzene (2,900 µg/L), MTBE (26.2 µg/L), naphthalene (307 µg/L), toluene (776 µg/L)
1,2,4-trimethylbenzene (662 µg/L) and total xylenes (2012 µg/L) were detected at concentrations
above their respective NCAC 15A 2L standards in well MW-5. Bromodichloromethane (2.6 µg/L),
not related to the petroleum release, was detected above its 2L standard in well MW-11. Various
other petroleum constituents were detected in wells MW-5 and MW-11 at concentrations below
their respective 2L standards. Contaminants of concern were not detected above the laboratory
method detection limits (MDLs) in wells MW-1 or MW-4.
Based on information obtained during the completion of these assessment activities, Terracon
provides the following conclusions and findings.
No free product was encountered in the groundwater at the site.
1,2-Dichloroethane (957 µg/L) was detected in monitoring well MW-5 above its GCL.

Benzene, MTBE, naphthalene, toluene, 1,2,4-trimethylbenzene and total xylenes were
detected at concentrations above their respective 2L standards in well MW-5.
Bromodichloromethane was also detected above its 2L standard in well MW-11. Other
constituents of concern were detected in the two wells at concentrations below the 2L
standards.
Constituents of concern were not detected in wells MW-1 or MW-4 above the MDLs.
Based on the analytical results, many of the petroleum constituent concentrations in well
MW-5 have increased (apparent rebound) since the injection event was conducted in 2018.
Petroleum constituents have shown a 100 percent reduction in well MW-11 since the injection
event in 2018.
Based on the findings of our assessment activities, the following recommendations are provided for
the site.
Terracon recommends removing the injection cap from MW-5 by cutting the PVC pipe for
the well so an O-Sox insert can be placed inside of the well during the next sampling event.
Terracon recommends continued semi-annual sampling of the on-site monitoring wells
(September 2020).
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to document the groundwater sampling event conducted in March
2020, approximately two years after injection activities were conducted at the Brack Griffin
property in February 2018. The site is located at 2601 Marshville-Olive Branch Road in
Marshville, Union County, North Carolina (Figure 1). This Subsequent Corrective Action
Performance Report was prepared for the site in response to a request by NCDEQ Incident
Manager, Ms. Sharon Ghiold with the NCDEQ Division of Waste Management, State Lead
Program.
The Corrective Action Performance Report was prepared in general accordance with the 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
professional geologist (North Carolina License No. 1015).
C.1 Site Setting
The Brack Griffin site is currently occupied by a thrift shop with gravel and grass-covered areas.
The adjacent properties to the north, west and south are developed as rural residences. An
adjacent property to the southeast is occupied by a former gasoline station identified as the
Benton Nance Grocery. The site and surrounding properties are depicted in Figure 2.

C.2 Release Summary
Reportedly, a petroleum release was discovered at the site in 1999 related to a 500-gallon
gasoline UST. Soil samples collected at the time of UST removal activities indicated elevated
levels of gasoline and diesel range petroleum hydrocarbons at the base of the UST excavation.
Reportedly, a second UST was suspected of being located to the west of the 500-gallon UST but
no other tanks were found following investigative excavations. The adjacent property located to
the southeast of the site (Former Benton Nance Grocery, Incident No. 18563) is currently an
active LUST incident. A chronological summary of petroleum releases and assessment activities
at the site is included in the following section of the report.
C.4 Previous Investigations
According to a Groundwater Monitoring Report by S&ME dated February 16, 2012, previous
assessment activities conducted at the site included the following investigations.
On September 2, 1999, OK Enterprises (OKE), Inc. removed a 500-gallon gasoline UST
from the Brack Griffin property. S&ME monitored the removal of the UST and collected
soil samples as required by NCDEQ guidelines. Two soil samples were collected from
the UST excavation at depths of approximately 6.5 and 7 feet bgs. Results of laboratory
analyses indicated the presence of gasoline range organics (GRO) and diesel range
organics (DRO) in both samples at levels exceeding the regulatory action level. A second
gasoline tank was suspected of being located on the site between Old Goldmine Road
and the on-site building; however, test pits did not identify evidence of another tank. The
tank basin and test pit excavations were backfilled with gravel. Petroleum impacted soils
were disposed at an off-site facility.
On February 14, 2000, S&ME sampled eight residential water supply wells (WSW-1
through WSW-3, WSW-5, WSW-8 through WSW-10 and WSW-12) on properties near the
release incident. Laboratory results indicated MTBE was detected in two supply wells
(WSW-8 and WSW-12). Well WSW-8 is located on the Benton Nance Property to the
southeast and well WSW-12 is located to the south of the site.
On May 2, 2001, S&ME re-sampled the eight residential water supply wells. Laboratory
results detected MTBE at a concentration below the 2L standard in supply well WSW-8
located on the former Benton Nance Grocery property. On March 26, 2002, S&ME
sampled three additional supply wells (WSW-6, WSW-7 and WSW-13) and the previous
eight residential supply wells. Laboratory results indicated MTBE was detected below the
2L standard at that time in supply well WSW-8; however, the detected concentration would
exceed the currently established standard for MTBE.
TRC Environmental Corporation completed a Comprehensive Site Assessment (CSA)
Addendum, dated March 21, 2003, for the former Benton Nance Grocery property that

Responsive ■Resourceful ■Reliable 5
included soil and groundwater sampling and analysis. The findings presented in the CSA
report suggested petroleum constituents from the release on the Benton Nance Grocery
site had migrated onto the Brack Griffin property.
In July 2009, S&ME sampled three on-site monitoring wells (MW-4, MW-5 and MW-11)
and three residential water supply wells (WSW-1, WSW-2 and WSW-12). Benzene and
1,2-dichloroethane were detected above 2L standards in wells MW-4 and MW-11.
Benzene and 1,2-dichloroethane were also detected in well MW-5 at concentrations of
15,000 µg/L and 1,510 µg/L, respectively, which were above their respective GCLs. The
water supply well identified as WSW-12 contained MTBE at a concentration above the
current 2L standard.
In February 2010, S&ME completed a groundwater monitoring event that detected multiple
petroleum constituents in well MW-5 above their respective 2L standards. Benzene was
detected in well MW-5 at a concentration of 12,000 µg/L, which is above its GCL. Benzene
and naphthalene were the only constituents detected above their 2L standards in well
MW-11. Monitoring well MW-4 contained no detected petroleum constituents above
laboratory detection limits.
In September 2011, S&ME sampled monitoring well MW-11 and supply wells WSW-1 and
WSW-2. Analytical results indicated benzene was the only petroleum constituent detected
above the 2L standard in well MW-11 and no constituents were detected in supply wells
WSW-1 and WSW-2.
An 8-hour Aggressive Fluid Vapor Recovery (AFVR) event was performed by S&ME in
April 2012 at monitoring well MW-5 to reduce the levels of petroleum constituents.
Reportedly, 24 gallons of fluid were recovered and 8 gallons (calculated) of petroleum
hydrocarbons were recovered in the vapor phase. One week following the AFVR event,
S&ME collected groundwater samples from monitoring well MW-5. Analytical results
indicated that although constituent concentrations decreased, targeted compounds
(benzene and 1,2-dichloroethane) remained at levels above their respective GCLs.
In March 2013, Crawford Environmental sampled monitoring well MW-11 and supply wells WSW-
1 and WSW-2. Analytical results indicated benzene and naphthalene were detected above their
respective 2L standards in well MW-11 but no petroleum constituents were detected in the water
supply wells.
In April 2015, Terracon collected groundwater samples from on-site monitoring wells MW-4, MW-
5 and MW-11 and water supply wells WSW-2 and WSW-12. According to the laboratory analytical
report, benzene and 1,2-dichloroethane were detected in monitoring well MW-5 above their
respective GCLs. Various other petroleum constituents were detected above their 2L standards
in wells MW-5 and MW-11. MTBE was detected in supply well WSW-12 above its 2L standard.

No target analytes were identified at concentrations above the MDLs in the water samples
collected from monitoring well MW-4 and water supply well WSW-2.
On March 15, 2016, Terracon conducted a Ground Penetrating Radar/Electromagnetic (GPR/EM)
survey to identify potential metallic objects and former excavations in the subsurface soils at the
site and to install a monitoring well (MW-1) in the former tank basin. The GPR/EM survey did not
reveal indications of a UST on the site or within the road between the site and the former Benton
Nance Grocery property.
On March 18, 2016, Terracon collected groundwater samples from monitoring wells MW-1, MW-
5 and MW-11. Benzene and 1,2-dichloroethane were detected in well MW-5 above their
respective GCLs. Various other constituents were detected in wells MW-1, MW-5 and MW-11
above their 2L standards. Terracon also installed an absorbent sock into well MW-5 and three O-
Sox inserts into well MW-11.
In May 2017, Terracon collected groundwater samples from wells MW-1, MW-5 and MW-11.
Benzene and 1,2-dichloroethane were detected in well MW-5 above their respective GCLs.
Various other constituents were detected in wells MW-5 and MW-11 above their 2L standards.
Target constituents were not detected in well MW-1 above their respective 2L standards.
In January 2018, Terracon collected groundwater samples from wells MW-1, MW-5 and MW-11
and removed the well sock inserts from wells MW-5 and MW-11. Benzene and 1,2-dichloroethane
were detected in well MW-5 above GCLs. Various other contaminant concentrations were
detected in wells MW-5 and MW-11 above their respective 2L standards.
At the direction of the NCDEQ, Terracon mobilized to the site on February 12, 13 and 14, 2018
to provide oversight and document injection activities at the Brack Griffin property. Terracon
oversaw the installation of four injection points using DPT technology. The target depth for the
injection points on the site was 32 feet bgs; however, due to the presence of rock at depths
ranging from 9 to 29 feet bgs, the target depth was not reached. Injection points were advanced
from 17 feet to 29 feet bgs. The locations of the injection points are shown on Figure 2. The
solution used on the site was a slurry mixture of hydrogen peroxide (H2O2), sodium persulfate
(Na2S2O8) and zero valence iron (ZVI). The combined use of these chemicals produces long term
oxidation within the subsurface. Terracon also oversaw the injection of a sodium persulfate and
hydrogen peroxide slurry into on-site wells MW-5 and MW-11 and off-site well MW-6 located on
the Benton Nance Property. Zero valence iron was not used as an injectant in the on-site wells
because the 0.10 slot screen width in the monitoring wells would not allow the solids to pass
through the screen. A total of approximately 920 gallons of solution was used during injection
activities on the site.
In July 2018, Terracon collected groundwater samples from wells MW-1, MW-4, MW-5 and MW-
11 to evaluate groundwater conditions after injection activities were completed in February 2018.

According to the analytical report, 1,2-dichloroethane was detected in well MW-5 at a
concentration above GCLs. Various other petroleum constituents were detected in well MW-5
above their respective 2L standards. Bromomethane, bromodichloromethane, chloromethane
and 1,2-dichloroethane were detected above their respective 2L standards in well MW-11. Based
on the historical analytical data, petroleum concentrations significantly decreased in well MW-5
after the injection event conducted in February 2018.
In February 2019, Terracon collected groundwater samples from monitoring wells MW-1, MW-4,
MW-5 and MW-11 to evaluate groundwater conditions. According to the laboratory analytical
report, 1,2-dichloroethane was detected in monitoring well MW-5 at a concentration above GCLs.
Various other petroleum constituents were detected at concentrations above their respective 2L
standards in well MW-5. Chloromethane was detected at a concentration above the established
2L standard in well MW-11. Based on the historical analytical data, constituent concentrations
generally increased in well MW-5 and decreased in well MW-11.
In September 2019, Terracon collected groundwater samples from monitoring wells MW-1, MW-
5 and MW-11 to evaluate groundwater conditions. According to the analytical results, 1,2-
dichloroethane was detected in well MW-5 at a concentration that exceeded its GCL. Benzene,
bromomethane, 1,2-dicholorpropane, MTBE, naphthalene, 1,2,4-trimethylbenzene and total
xylenes were detected in well MW-5 above their respective 2L standards. Bromomethane,
chloromethane, 1,2-dichloroethane and methylene chloride were detected in well MW-11 above
their respective 2L standards. Methylene chloride has not historically been detected in well MW-
11 and is a common laboratory artifact. Based on historical data, constituent concentration trends
in well MW-5 vary whereas some constituents have increased while others have decreased.
C.3 Water Supply Wells
Based on historical receptor information, eleven water-supply wells were identified within 1,500
feet of the source area. Terracon did not conduct a water supply well/receptor survey during this
assessment. Municipal water service is not available to the site and surrounding properties.
C.4 Surface Water
The site is situated on the eastern flank of a local topographic high that is generally located to the
west of Old Goldmine Road. The source area is located approximately 330 feet southwest of
unnamed tributaries of Gourdvine Creek which discharges into Richardson Creek and Rocky
River. Surface waters are depicted on Figure 1.
C.5 Land Use Information
The adjacent properties to the north, west and south are developed as rural residences. An
adjacent property to the southeast is occupied by a vacant gasoline station identified as a heating
and air conditioning repair shop. The site and surrounding properties are depicted in Figure 2.

D. ASSESSMENT INFORMATION
D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.
Olive Branch, North Carolina, USGS 7.5-minute series topographic map, dated 1970 (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.

Conservation Service, Web Soil Survey via the Internet,
http://websoilsurvey.nrcs.usda.gov/app/.
The site is located within the Carolina Slate Belt of the Piedmont Physiographic Province. The
Piedmont Physiographic Province generally consists of low to medium elevation, rounded hills
and long rolling northeast to southwest trending ridges with incised creeks and river channels.
Rocks in the site area are described as metamorphosed mudstone and argillite.
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 Union County, depicts soils at the site as Badin
channery silt loam (BaB).
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 from topographic maps and historical data, groundwater is expected to flow generally to
the northeast from the site.
D.2 Remediation Activities
D.2.1 Free Product Evaluation
Free product was not encountered at the site.
D.2.2 Groundwater Sampling Activities
Terracon mobilized to the site on March 5, 2020 to collect groundwater samples from monitoring
wells MW-1, MW-4, MW-5 and MW-11 and water supply wells WSW-1 and WSW-2 for laboratory
analysis. The approximate locations of the monitoring wells are shown on the Site Plan (Figure
2). Prior to sampling, Terracon gauged the groundwater levels in the monitoring wells. During this
sampling event, depth to groundwater in the monitoring wells ranged from approximately 1.56
feet (well MW-1) below ground surface (bgs) to 15.25 feet bgs in well MW-4. Based on
groundwater level measurements, the estimated groundwater flow direction is to the
east/northeast. Current and historical groundwater depth measurements are provided in Table 2.
Terracon was unable to sample the water supply wells due to no responses to our water supply
well letters and no one at home to grant us access.
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 VOCs by Standard
Method 6200B, including MTBE, IPE and EDB.
D.2.3 Analytical Results
According to the laboratory analytical report, 1,2-dichloroethane (957 micrograms per liter [µg/L])
was detected in monitoring well MW-5 at a concentration above its GCL. Benzene (2,900 µg/L),
MTBE (26.2 µg/L), naphthalene (307 µg/L), toluene (776 µg/L) 1,2,4-trimethylbenzene (662 µg/L)
and total xylenes (2012 µg/L) were detected at concentrations above their respective NCAC 15A
2L standards in well MW-5. Bromodichloromethane (2.6 µg/L), not related to the petroleum
release, was detected above its 2L standard in well MW-11. Various other petroleum constituents
were detected in wells MW-5 and MW-11 at concentrations below their respective 2L standards.
Contaminants of concern were not detected above the laboratory MDLs in wells MW-1 or MW-4.
The groundwater analytical results from the monitoring wells are summarized in Table 3 and are
depicted on Figure 5. A copy of the laboratory analytical reports is provided in Appendix A.
