Benzene and naphthalene were detected at concentrations above their respective 2L
standards in wells MW-5, MW-12, and DMW-1. Well MW-5 also contained concentrations of
toluene, 1,2,4-trimethylbenzene, and total xylenes above 2L Standards.
VOCs were not detected in wells MW-1 or WSW-1 above the laboratory method detection
limits (MDLs), except for an estimated concentration of methylene chloride (1.7J µg/L) in
water supply well WSW-1, which was also detected in the method blank and is suspected to
be a laboratory contaminant.
Depth to groundwater ranged from approximately 2.32 feet (MW-1) below ground surface
(bgs) to 22.04 feet bgs (MW-5). Based on Terracon’s interpretation of topographic contours
and historical groundwater data, groundwater flow direction is estimated to the east.
Based on the analytical results, many of the petroleum constituent concentrations in well MW-5 have
rebounded since the injection event in 2018, with benzene increasing slightly since the sampling
event in June 2021.
Based on the findings of our assessment activities, the following recommendations are provided for
the site.
Terracon recommends evaluating various bioremediation technologies to facilitate the
degradation of VOCs in the subsurface.
C. SITE HISTORY AND CHARACTERIZATION
Terracon completed this Monitoring Report to document field activities conducted at the Brack
Griffin Property located at 2601 Marshville-Olive Branch Road, Marshville County, North Carolina.
Field activities included the installation of two monitoring wells (DMW-1 and MW-12), and a
groundwater sampling event, completed in November and December 2022. The site is located at
2601 Marshville-Olive Branch Road in Marshville, Union County, North Carolina (Figure 1).

C.1 Site Setting The Brack Griffin site is currently occupied by a thrift shop with gravel and grass-covered areas.
The properties to the north, west and south are developed as rural residences. The 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 property located to the
southeast of the Brack Griffin Property is currently an active LUST incident, identified as the
Former Benton Nance Grocery, Incident No. 18563.

C.3 Previous 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 two soil samples
from the UST excavation and 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. 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 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 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-DCA were
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. Benzene was detected in
well MW-5 above the GCL at a concentration of 12,000 µg/L

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 VOCs were not 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.
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-DCA)
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, and petroleum constituents were not detected in the water
supply wells.

In April 2015, Terracon collected groundwater samples from monitoring wells MW-4, MW-5 and
MW-11, and water supply wells WSW-2 and WSW-12. Benzene and 1,2-DCA were detected in
monitoring well MW-5 above their respective GCLs. MTBE was detected in supply well WSW-12
above the 2L standard.

In March 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. Terracon collected groundwater samples from monitoring wells MW-1,
MW-5, and MW-11. Benzene and 1,2-DCA were detected in well MW-5 above their respective
GCLs. 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-DCA were detected in well MW-5 above their respective GCLs.

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-DCA were
detected in well MW-5 above GCLs at concentrations of 13,000 µg/L and 1,000 µg/L, respectively.

In February 2018, Terracon oversaw and documented an injection event. Injection points were
advanced by direct-push technologies from 17 feet to 29 feet bgs. The solution used on the site
was a slurry mixture of hydrogen peroxide (H2O2), sodium persulfate (Na2S2O8) and zero valence
iron (ZVI). Additionally, sodium persulfate and hydrogen peroxide slurry were injected into on-site
wells MW-5 and MW-11 and off-site well MW-6 located on the Benton Nance Property. A total of
approximately 920 gallons of solution was used during injection activities.

In July 2018, Terracon collected groundwater samples from wells MW-1, MW-4, MW-5, and MW-
11. The analytical report indicated 1,2-DCA was detected in well MW-5 at 748 µg/L, above the

GCL, though decreased as compared to the January 2018 results. Benzene was detected in well
MW-5 at a concentration of 194 µg/L, and significantly reduced as compared to the prior sampling
results.

In March 2019 and September 2019, Terracon collected groundwater samples from monitoring
wells MW-1, MW-4, MW-5, and MW-11. The laboratory reports indicated well MW-5 contained
1,2-DCA at concentrations above the GCL.

In March 2020, Terracon collected groundwater samples from wells MW-1, MW-4, MW-5, and
MW-11, and water supply wells WSW-1 and WSW-2. According to the laboratory analytical
report, 1,2-DCA was detected in monitoring well MW-5 at a concentration above the GCL. Based
on historical data, VOC concentrations in well MW-5 appeared to rebound following the 2018
injection event.

Terracon collected groundwater samples from monitoring well MW-11 in March 2021, and MW-5
in June 2021. According to the analytical results, chloromethane was detected in well MW-11
above the 2L standard. 1,2-DCA exceeded the GCL in well MW-5, and benzene, EDB,
naphthalene, toluene, 1,2,4-trimethylbenzene, and total xylenes were detected above their
respective 2L standards.

C.4 Water Supply Wells
Based on historical receptor information, eleven water-supply wells were identified within 1,500
feet of the source area, and municipal water service is not available to the site and surrounding
properties. Two water supply wells are located within 250 feet of the source area. Water supply
well WSW-2, located at 7007 Old Gold Mine Road, is approximately 170 feet to the north of the
site. Water supply well WSW-8, located at 2602 Marshville-Olive Branch Road, is approximately
245 feet to the southeast of the site, but is monitored in association with the Benton Nance
incident.

C.5 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. The
property located to the southeast of the Brack Griffin Property is currently an active LUST incident,
identified as the Former Benton Nance Grocery, Incident No. 18563. The building appears to be
vacant and was 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.
Soil Survey of Union 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 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” (PWR) or
saprolite. Information obtained from the Web Soil Survey for Union County, depicts soils at the
site as Badin channery silt loam (BaB).

Soils observed during the installation of monitoring wells MW-12 and DMW-1 consisted of tan silt
to approximately 3 feet below ground surface (ft-bgs), followed by PWR interlayered with tan silt
to a depth of 33 ft-bgs. Competent rock was encountered during the installation of DMW-1 at an
approximate depth of 33 ft-bgs, and a water bearing fracture was encountered at a depth of
approximately 41 ft-bgs.

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, shallow groundwater is expected to flow
generally to the east from the site.

Vertical gradient calculations, established by Darcy’s Law, between monitoring wells MW-12 and
DMW-1 indicate a 0.041 feet per foot magnitude flow in the downward direction. Horizontal flow
across the site wells was not calculated as the recently sampled monitoring wells are oriented in
line with each other.

D.2 Monitoring Well Installation Activities On November 21 and 22, 2022, Terracon supervised in the installation of Type II monitoring well
MW-12, and Type III monitoring well DMW-1. Drilling activities were completed by Environmental
Drilling and Probing Services, LLC (EDPS), a North Carolina certified well driller. Prior to field
work, Terracon contacted 811 to locate public utilities and subcontracted a private utility locator
to identify subsurface utilities that may be present in the areas of investigation. Drilling was
conducted using a Canterra CT-450 combination drill rig and air rotary drilling methods.

The boring for MW-12 was advanced to a depth of approximately 30 ft-bgs, using a 6-inch
diameter air hammer. A 10-feet section of 2-inch diameter schedule 40 polyvinyl chloride (PVC)
0.010-inch factory slotted well screen and solid riser were placed into the borehole without a sand
filter pack, allowing groundwater to seep into the boring. The following day, at the direction of the
NCDEQ Incident Manager, the boring was advanced an additional three feet (33 ft-bgs total), and
a Type II monitoring well was installed, constructed with 15 feet of 2-inch diameter schedule 40
PVC 0.010-inch factory slotted well screen and solid riser to the surface.

The boring for the outer casing of DMW-1 was advanced to a depth of approximately 35 ft-bgs,
using an 8-inch roller tri-cone bit. The outer casing for the Type III monitoring well consisted of a
6-inch diameter schedule 40 PVC solid riser, installed to 35 ft-bgs and grouted to land surface.
The following day, the boring for the inner casing of DMW-1 was advanced through competent
rock to a depth of approximately 43 ft-bgs using a 6-inch diameter air hammer. The well was
constructed with five feet of 2-inch diameter schedule 40 PVC 0.010-inch factory slotted well
screen and solid riser to the surface.

A sand filter pack was placed in each well anulus from the bottom of the boring to approximately
two feet above the top of screen, followed by an approximate two-foot bentonite seal hydrated

with clean potable water. The remainder of the borehole annulus was filled with a grout slurry to
near ground surface.

The monitoring wells were finished with flush-mounted, traffic-rated 8-inch diameter steel well
boxes, finished with a two-foot square concrete pad, and secured with locking expansion plugs.
Locations of the newly installed monitoring wells are depicted on Figure 2. The well construction
records provided by the drillers are included in Appendix A.

EDPS attempted to develop monitoring wells MW-12 and DMW-1 with a submersible pump until
turbidity was visibly reduced and the wells were pumped dry and allowed to recharge at least
three times. During the groundwater sampling event completed on December 8, 2022, the top of
casing elevations for the newly installed monitoring wells were measured relative to the existing
monitoring well network, using a differential leveling method. Field notes are included in
Appendix B.

D.3 Sampling Activities
D.3.1 Free Product Evaluation
Free product was not encountered at the site.

D.3.2 Groundwater Sampling Activities
At the request of the NCDEQ Incident Manager and property owner, Terracon mobilized to the
site on September 22, 2022, to collect a sample from water supply well WSW-1. On December 8,
2022, Terracon collected groundwater samples from monitoring wells MW-1, MW-5, MW-11, MW-
12, and DMW-1 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 2.32 feet bgs in well MW-1 to 22.04 feet bgs in well MW-5. Based on
groundwater level measurements, historical data, and area topography, the estimated
groundwater flow direction is to the east. Of note, monitoring well MW-1 is not included in
groundwater flow direction interpretation, due to the difference of well construction and screened
intervals compared to the other on-site Type II monitoring wells. Current and historical
groundwater depth measurements are provided in Table 2. Groundwater elevations are depicted
on Figure 4; however, monitoring wells MW-5, MW-11, and MW-12 are in line with each other,
preventing the triangulation and interpretation of groundwater flow contours.

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.

D.3.3 Analytical Results
According to the laboratory analytical report, 1,2-DCA (824 µg/L) was detected in monitoring well
MW-5 at a concentration above the GCL of 400 µg/L. Additionally, benzene (4,110 µg/L),
naphthalene (251 µg/L), toluene (1,130 µg/L) 1,2,4-trimethylbenzene (496 µg/L) and total xylenes
(2,019 µg/L) were detected at concentrations above their respective 2L standards in well MW-5.

The sample collected from monitoring well MW-12 contained concentrations of benzene (909
µg/L), 1,2-DCA (75.2 µg/L), and naphthalene (26.5 µg/L) above 2L standards. The sample
collected from monitoring well DMW-1 contained concentrations of benzene (629 µg/L), 1,2-DCA
(121 µg/L), and naphthalene (19.3 µg/L) exceeding their respective 2L standards. Additional
VOCs were detected in at concentrations below their respective 2L standards in the above-
referenced monitoring wells.

MTBE was detected in water supply well WSW-12 at concentration of 59.3 µg/L, above the 2L
standard of 20 µg/L. The sample collected from water supply well WSW-1 contained an estimated
concentration of methylene chloride (1.7J µg/L), which was also detected in the method blank and
is suspected to be a laboratory contaminant.

VOCs were not detected above the laboratory MDLs in the samples collected from wells MW-1
or WSW-1 (except for methylene chloride). The groundwater analytical results are summarized in
Table 3 and are depicted on Figure 5. 1,2-DCA concentrations are depicted on Figure 6. A copy
of the laboratory analytical reports is provided in Appendix C.
E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of these assessment activities, Terracon
provides the following conclusions and findings.
Free product was not encountered.
1,2-DCA exceeded the GCL in monitoring well MW-5 at a concentration of 824 µg/L, and
exceeded the 2L Standard in monitoring wells MW-12 and DMW-1.
MTBE exceeded the 2L Standard in water supply well WSW-12 at a concentration of 59.3
µg/L.
Multiple VOCs were detected at concentrations above 2L Standards in the samples collected
from monitoring wells MW-5, MW-11, MW-12, and DMW-1.
VOCs were not detected in wells MW-1 or WSW-1 above MDLs, except for an estimated
concentration of methylene chloride (1.7J µg/L) in water supply well WSW-1, which was also
detected in the method blank and is suspected to be a laboratory contaminant.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
