B. EXECUTIVE SUMMARY
The purpose of this report is to evaluate the current status of groundwater quality after the
introduction of hydrogen peroxide within injection wells installed at the Lewis Service Station
(Incident No. 3701) site. Hydrogen peroxide was previously deployed via RemRx™ sleeves (in the
form of anhydrous pellets of sodium percarbonate) in April 2022 within five treatment wells installed
within the source area at the site. Terracon previously completed 3-month (July 2022) and 6-month
(October 2022) post-injection groundwater sampling activities of three source area monitoring wells
to evaluate the efficacy of the hydrogen peroxide at degrading ethylene dibromide (EDB), the sole
contaminant at the site remaining above its Gross Contaminant Level (GCL). While EDB was not
detected above its laboratory method detection limit (MDL) during these two post-deployment
groundwater sampling events, it was not clear whether the lack of detections was due to the
degradation of the EDB by the hydrogen peroxide or an artifact of a drop in depth to groundwater,
which may have prevented the sampling from identifying remnant contamination that may exist at
the top of the vadose zone.

On March 23, 2023, Terracon mobilized to the site to make observations of the RemRx™ sleeves
and complete a groundwater gauging event. Upon arrival at the site, it was determined that some of
the cabling suspending the RemRx™ sleeves from the treatment well caps had broken and each
sleeve could not be removed from subsurface. As such, Terracon could not determine how much of
the hydrogen peroxide may have dissolved into the aquifer. Terracon also gauged the depth to
groundwater in the three source area wells. Depth to groundwater ranged from 22.78 to 23.27 feet
below top of casing (bTOC). As historical groundwater gauging data indicates that EDB
concentrations above its GCL have previously been detected when the depth to groundwater has
been between approximately 18 and 20 feet bTOC, Terracon did not collect groundwater samples
during the March 2023 mobilization.

On May 19, 2023, Terracon remobilized to the site with RemRx™ to extricate the broken sleeves,
conduct additional groundwater gauging, and collect groundwater samples. Upon removal of the
broken sleeves, RemRx™ deployed the remainder of the hydrogen peroxide that had not been

introduced at the site as previously intended (approximately ¼ of the total planned 900 pounds).
The hydrogen peroxide was introduced as a powder material directly into the treatment wells so that
empty sleeves would not require removal in the future. While the depth to groundwater was
observed ranging from 22.18 to 22.57 feet bTOC, in accordance with TA-04, Terracon collected
groundwater samples from the three source area monitoring wells (MW-1, VMW-1, and RW-1). The
monitoring wells were purged a minimum of three well volumes prior to sampling. The groundwater
samples were submitted for laboratory analysis of volatile organic compounds (VOCs) by EPA
Method 6200B, including MTBE, IPE and EDB and iron by EPA Method 200.7. Based on the
laboratory analytical results, EDB was not detected above its MDL in VMW-1 and RW-1. EDB (2.6
µg/L) was detected above its 2L standard (0.02 µg/L) in groundwater from monitoring well MW-1;
however, the concentration detected does not exceed its GCL (50 µg/L).

Based on information obtained during the completion of these assessment activities, Terracon
provides the following conclusions and findings.

The absence of EDB concentrations in source area monitoring wells could be attributable to
effective reduction from the application of RemRx™ hydrogen peroxide, an artifact of the observed
drop in the depth to groundwater at the site post-deployment, or a combination of the two.

Based on the findings of our assessment activities, the following comments and recommendations are
provided for the site.
Continue groundwater gauging events on a periodic basis. Should sustained wet conditions be
encountered within the site area, a gauging event should be completed regardless of a set
frequency. During the gauging events, should a shallower groundwater elevation be encountered
(approximately 20 feet bTOC or shallower), groundwater samples should be collected to determine
if possible remnant vadose zone impacts continue to result in dissolved EDB concentrations
exceeding its GCL.
Once EDB concentrations have been reduced below the GCL, the site would then be eligible for
closure with issuance of a Notice of Residual Petroleum (NORP) since prior fate and transport
modeling has indicated low risk to the nearest receptors.

C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate the current status of groundwater quality after the
introduction of hydrogen peroxide within injection wells installed at the Lewis Service Station
(Incident No. 3701) site. Hydrogen peroxide was previously deployed via RemRx™ sleeves (in the
form of anhydrous pellets of sodium percarbonate) in April 2022 within five treatment wells installed

degradation of the EDB by the hydrogen peroxide or an artifact a drop in depth to groundwater,
which may have prevented the sampling from identifying remnant contamination that might possibly
exist at the top of the smear zone.

The site is located at 4733 Fallston Road in Fallston, Cleveland County, North Carolina (Figure 1).
This report was prepared for the site in response to a request by Mr. Mark Petermann, NCDEQ
Incident Manager with the Division of Waste Management, State Lead Program. The 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 September 2022, under the supervision of Mr. William
O. Frazier, a North Carolina registered professional geologist (North Carolina License No. 2576).

C.1 Site Setting
The site is located within an area primarily developed as commercial. A park is located on the
adjacent property to the north and a retail store is located on the adjacent property to the south.
The site is bound to the east by Fallston Road and a residence is located on the adjacent property
to the west. Specific land uses are further described in Section C.6 below.

C.2 Release Summary
Based on regulatory file review information, the site formerly operated two 1,000-gallon gasoline
USTs, one 1,000-gallon kerosene UST, and two ASTs related to on-site fueling operations. A
potential release was discovered on December 27 and 28, 1994. The suspected release was from
the 1,000-gallon gasoline UST located near the southeastern corner of the on-site building.
Historical UST information is provided in Table 1.

USTs, one 1,000-gallon kerosene UST, and two ASTs related to on-site fueling operations. A
potential release was discovered on December 27 and 28, 1994. The suspected release was from
the 1,000-gallon gasoline UST located near the southeastern corner of the on-site building.
Reportedly, the two 1,000-gallon gasoline USTs were abandoned in place and the 1,000-gallon
kerosene UST was removed from the site.

Most of the monitoring well network was installed during Comprehensive Site Assessment (CSA)
activities in 1995. Between 1999 and 2003, numerous monitoring events were completed at the site.
In addition, three Aggressive Fluid and Vapor Recovery events were completed during that time.
The monitoring well network has been sampled on an approximate annual basis since 2012. A
receptor survey conducted in 2016 by Shield Engineering, Inc. (Shield) identified two water supply
wells within 1,500 feet of the source area (Table 2).

In May 2016, Shield conducted a 96-hour Mobile Multiphase Extraction Event (MMPE) at on-site
wells MW-1, VMW-1 and RW-1. Approximately 3,600 gallons of dissolved phase impacted
groundwater were recovered during the MMPE event. An estimated 32 gallons of free product
(gasoline) were removed from the site as vapor. A subsequent well sampling event on June 14,
2016 indicated contaminant concentrations had generally decreased as a result of the MMPE event.
Constituent concentrations were below their respective GCLs but remained above their respective
2L standards.

In August 2017, Terracon conducted a groundwater sampling event on wells MW-1, RW-1, and
VMW-1. Groundwater depths ranged from 26.60 feet (well RW-1) to 26.97 feet (well VMW-1) bgs.
Benzene was detected in well RW-1 above its GCL and various constituents were detected above
their respective 2L standards in wells VWM-1 and MW-1.

In June 2019, Terracon sampled monitoring wells MW-1 through MW-6, MW-8, RW-1, VMW-1 and
SSMW-2 (from adjoining Stamey Store property to the east). VOC concentrations had decreased
dramatically (e.g. benzene decreased by an order of magnitude and no longer exceeded its GCL in
well RW-1, and a maximum concentration of 509 µg/L in well MW-1) except for EDB, which was
identified above its GCL in well MW-1. Terracon also collected additional samples from wells MW-
2, VMW-1, and RW-1 for analysis of natural attenuation parameters including dissolved gases
(ethane, ethene and methane), dissolved oxygen, ferrous iron, nitrate, nitrite, sulfate, and alkalinity.
The three wells were also evaluated for biodegradation potential using QuantArray-Petro to identify
aerobic and anaerobic biodegradation organisms.

These results indicate wells VMW-1 and RW-1 contain microorganisms responsible for aerobic
biodegradation of BTEX and MTBE, specifically Methylibium petroleiphilum (PM1), Phenol
Hydroxylase (PHE), Toluene 2 Monooxygenase (RDEG), Toluene Ring Hydroxylating
Monooxygenases (RMO), and Ethylbenzene/Isopropylbenzene Dioxygenase (EDO). Well RW-1
contains the highest volume of microorganisms. Well RW-1 also contains Naphthalene
Dioxygenase (NAH), which is a microorganism responsible for aerobic biodegradation of PAHs and

alkanes; however, the population is small. Benzoyl Coenzyme A Reductase (BCR) and
Benzylsuccinate Synthase (BSS) are microorganisms responsible for anaerobic biodegradation of
BTEX, while Naphthylmethylsuccinate Synthase (MNSSA), Naphthalene Carboxylase (ANC) and
Alkylsuccinate Synthase (ASSA), microorganisms responsible for anaerobic biodegradation of
PAHs and alkanes were also found in wells VMW-1 and RW-1. Other bacteria detected in the wells
included Total Eubacteria (EBAC) and Sulfate Reducing Bacteria (APS).

In March 2021, Terracon conducted a groundwater sampling event, which indicated that EDB was
the sole contaminant that remained above its GCL. At the request of NCDEQ, Terracon remobilized
to the site in July 2021 to complete slug testing of the source area monitoring wells in support of
contaminant fate and transport modeling to determine risk to the nearest receptor (WSW-Cotton
Gin) to the site. Terracon also collected groundwater samples so that RemRx™ could complete a
laboratory bench-scale treatability study to evaluate whether hydrogen peroxide can effectively
degrade EDB. Terracon’s fate and transport modeling indicated minimal risk to WSW-Cotton Gin,
indicating that the GCLs could be used as remediation targets for the site. RemRx™ determined
that iron-activated hydrogen peroxide can effectively degrade EDB as well as other contaminants
found at the site (e.g. benzene, naphthalene, etc.) at modest to high doses. A solid form of
hydrogen peroxide, sodium percarbonate, was also evaluated and found to be effective in
degrading contaminant concentrations. The reaction kinetics of sodium percarbonate are more
efficient at lower pH; as such, RemRx™ indicated an acid buffer may be necessary to adjust
groundwater pH if sodium percarbonate were chosen as a treatment for the site.

Terracon mobilized to the site in November 2021 to oversee the installation of five injection wells
(IW-01 through IW-05) via hollow-stem auger drilling methods. The planned depth of the injection
wells was approximately 27 feet below land surface (bls); however, during drilling, auger refusal
was encountered prior to this depth at IW-02, IW-03, and IW-04. The auger rig was able to reach
the target depth at IW-01 (installed to 27 feet bls) and IW-05 (installed to 30 feet bls). Terracon
remobilized to the site in March 2022 to oversee the installation of the remaining injection wells via
air rotary drilling. IW-02, IW-03, and IW-04 were each installed to depths of 38, 35, and 35 feet bls,
respectively.

On April 27, 2022, RemRx™ deployed approximately half of the planned 900 pounds of hydrogen
peroxide within the injection wells. RemRx™ mobilized to the site on a monthly basis to monitor the
pH levels in the source area wells to determine if buffering of the aquifer would be needed to
maintain pH levels suitable for degradation of EDB via the hydrogen peroxide. RemRx’s™ pH
measurements throughout the treatability study indicated that pH remained in a neutral range and
that buffering of the aquifer was not needed.

Terracon mobilized to the site with RemRx™ on July 29, 2022 and October 28, 2022 to collect
groundwater samples from on-site source area monitoring wells MW-1, RW-1, and VMW-1. Prior to
sample collection, Terracon gauged the groundwater level and RemRx™ evaluated how much
hydrogen peroxide had been released to the aquifer. During the July 2022 sampling event, depth to

groundwater in the monitoring wells ranged from approximately 24.30 feet (well RW-1) to 24.64 feet
(well VMW-1) below top of casing (bTOC). RemRx™ introduced additional hydrogen peroxide into
the sleeves deployed within the injection wells (IW-01, IW-02, IW-03, IW-04, and IW-05); however,
only about half of the sleeves required refreshment of the hydrogen peroxide.

During the July and October 2023 mobilizations, the depth to groundwater observed across the site
was approximately four to six feet deeper than recent historical measurements indicated; as such,
some of the hydrogen peroxide was not in contact with groundwater and had not dissolved. During
the October 2022 sampling event, depth to groundwater in the monitoring wells ranged from
approximately 25.82 feet (well RW-1) to 26.20 feet (well VMW-1). Due to the deeper water table,
much of the hydrogen peroxide had once again not dissolved. RemRx™ deployed additional
hydrogen peroxide where possible; however, at this time, approximately one-quarter of the planned
900 pounds of hydrogen peroxide has not been introduced to the injection wells, and hydrogen
peroxide remains undissolved within those wells. Based on the mobilizations completed after
deployment of the hydrogen peroxide, it is not clear whether the absence of EDB concentrations in
source area monitoring wells could be attributable to effective reduction from the application of
RemRx™ hydrogen peroxide, an artifact of the observed drop in the depth to groundwater at the
site post-deployment, or a combination of the two.

The analytical results of the historical monitoring events are summarized in Table 3. Historic
groundwater elevation data for the site-wide (including off-site) monitoring well network are
summarized in Table 4.

C.4 Water Supply Wells
Two water supply wells were identified within 1,500 feet of the source area as reported by Shield in
2016. Water supply well WSW-4, located on the adjacent property to the west, reportedly was used
to water vegetation in a nearby park located north of the site; however, during this sampling event,
the property owner informed Terracon that the supply well is inactive and his property has been
connected to municipal water. Water supply well WSW-Cotton Gin, located between 500 and 1,000
feet east of the source area, is reportedly used for washing vehicles and other machinery. Water
supply well information is summarized in Table 2. The approximate locations of the identified water
supply wells are shown on Figure 3.

C.5 Surface Water
An unnamed tributary of Buffalo Creek is located approximately 1,100 feet northeast and down-
gradient of the site. Surface waters are depicted on Figure 1.

C.6 Land Use Information
The former gas station site is presently occupied by Cool Cycle, Inc., a motorcycle repair shop. The
front of the property contains the former dispenser island beneath an overhead canopy structure.

Two apparent storage buildings are located at the rear (west) of the property. Terracon was not
provided access to the rear of the property; however, minor oil stains and typical motorcycle repair
operations were observed within the on-site building. The adjoining properties to the east, across
Fallston Road and south are commercial businesses. The adjoining property to the west is
developed as a single-family residence and a storage building. The adjoining property to the north is
a city park. The site and surrounding properties are depicted in Figures 1 and 2.

D. ASSESSMENT INFORMATION
D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.
Lawndale, North Carolina, USGS 7.5-minute topographic map, dated 2002 (Figure 1).
Geologic Map of North Carolina, dated 1985.
The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by

The site is located within the Inner Piedmont 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.
Underlying bedrock in the site area consists of biotite gneiss and 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 Web Soil Survey for Cleveland County, depicts soils at the site as Cecil-Urban
land complex (CeB).

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 data, groundwater is expected to flow to the northeast from the site.

D.4.2 Groundwater Sampling Activities
March 2023 Mobilization
On March 23, 2023, Terracon mobilized to the site to make observations of the RemRx™ sleeves
and complete a groundwater gauging event. Upon arrival at the site, it was determined that some of
the cabling suspending the RemRx™ sleeves from the treatment well caps had broken and each
sleeve could not be removed from subsurface. As such, Terracon could not determine how much of
the hydrogen peroxide may have dissolved into the aquifer. Terracon gauged the depth to
groundwater in the three source area wells. Depth to groundwater ranged from 22.78 to 23.27 feet
bTOC. As historical groundwater gauging data indicates that EDB concentrations above its GCL
have previously been detected when the depth to groundwater has been between approximately 18
and 20 feet bTOC, Terracon did not collect groundwater samples during the March 2023
mobilization in accordance with TA-04.

May 2023 Mobilization
On May 19, 2023, Terracon remobilized to the site with RemRx™ to extricate the broken sleeves,
conduct additional groundwater gauging, and collect groundwater samples. Upon removal of the
broken sleeves, RemRx™ deployed the remainder of the hydrogen peroxide that had not been
introduced at the site as previously intended (approximately ¼ of the total planned 900 pounds).
The hydrogen peroxide was introduced as a powder material directly into the treatment wells so that
empty sleeves would not require removal in the future.

While the depth to groundwater was observed ranging from 22.18 to 22.57 feet bTOC, in
accordance with TA-04, Terracon collected groundwater samples from the three source area
monitoring wells (MW-1, VMW-1, and RW-1). The monitoring wells were purged a minimum of three

well volumes prior to sampling. The groundwater samples were submitted to Pace Analytical
Services, Inc. in Huntersville, North Carolina for analysis of VOCs by Standard Method 6200B,
including MTBE, IPE and EDB and iron by EPA Method 200.7. Groundwater parameters (e.g. pH,
oxidation-reduction potential, conductivity) were measured during purging using a YSI Pro
multimeter. The pH within the source area wells ranged from 6.3 to 7.3.

Copies of Terracon’s field notes are included in Appendix A. Current and historical groundwater
depth measurements for source area wells MW-1, RW-1, and VMW-1 are provided in Table 5.

D.4.3 Analytical Results
According to the laboratory analytical report, the following constituents were identified above their
2L standard) during the May 2023 monitoring events:
VOCs
▪ MW-1: benzene (44.9 µg/L); naphthalene (86.5 µg/L); 1,2,4-trimethylbenzene (734 µg/L);
and EDB (2.6 µg/L).
▪ VMW-1: benzene (275 µg/L); n-propylbenzene (141 µg/L); MTBE (209 µg/L); naphthalene
(46.6 µg/L); 1,2-dichloroethane (7.8 µg/L); and 1,2,4-trimethylbenzene (843 µg/L). EDB was
not detected above its laboratory MDL.
▪ RW-1: benzene (280 µg/L); n-propylbenzene (128 µg/L); MTBE (277 µg/L); naphthalene
(49.8 µg/L), 1,2-dichloroethane (9.4 µg/L); and 1,2,4-trimethylbenzene (676 µg/L). EDB was
not detected above its laboratory MDL.
Iron
Concentrations of iron were detected ranging from 20,900 to 35,600 µg/L, above its 2L Standard
(300 µg/L). It should be noted that the samples are representative of total (rather than dissolved)
concentrations. These data indicate that there is sufficient iron content within the aquifer to catalyze
Fenton’s reaction, which requires iron to act as an electron donor in the contaminant oxidation
process. The pH measured at the site appears sufficient for Fenton’s reaction to occur; however,
the reaction may be more efficient at lower pH values (3 to 4 pH).
The groundwater analytical results for source area wells MW-1, RW-1, and VMW-1 from the most
recent sampling event (May 2023) are summarized in Table 6 and are depicted on Figure 5. A
copy of the laboratory analytical report is provided in Appendix B.

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

The absence of EDB concentrations in source area monitoring wells could be attributable to
effective reduction from the application of RemRx™ hydrogen peroxide, an artifact of the observed
drop in the depth to groundwater at the site post-deployment, or a combination of the two.

Based on the findings of our assessment activities, the following comments and recommendations are
provided for the site.
Continue groundwater gauging events on a periodic basis. Should sustained wet conditions be
encountered within the site area, a gauging event should be completed regardless of a set
frequency. During the gauging events, should a shallower groundwater elevation be encountered
(approximately 20 feet bTOC or shallower), groundwater samples should be collected to determine
if possible remnant vadose zone impacts continue to result in dissolved EDB concentrations
exceeding its GCL.
Once EDB concentrations have been reduced below the GCL, the site would then be eligible for

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.
