EXECUTIVE SUMMARY
On behalf of Duke Energy Carolinas, LLC (Duke Energy), ERM NC, Inc. (ERM) has prepared this
Quarterly Groundwater Monitoring and Corrective Action Performance Report for the petroleum
underground storage tank (UST) Incident Number 40750 at Marshall Steam Station in Sherrills Ford,
Catawba County, North Carolina (Figure 1).
Past remedial activities related to Incident 40750 include removal of the UST and surrounding soil, and
implementation of a monitored natural attenuation (MNA) remedy. In response to a regulatory request, an
Air Sparge (AS) and Soil Vapor Extraction (SVE) system was installed at the Site and began operation on
June 29, 2023. Initial results indicate a decrease in constituent concentrations groundwater samples
collected adjacent to the former UST (MW-01) and increases in groundwater dissolved oxygen (DO)
concentrations, which suggest that injected air is penetrating the treatment zone. Increased concentrations
of oxygen in Site soil and groundwater is expected to accelerate biodegradation of VOC mass in the
subsurface. Constituents were not detected above applicable regulatory standards in downgradient
monitoring wells, indicating the remedy has not adversely impacted the nearest receptor, which is the intake
canal associated with Lake Norman located approximately 80 feet east of the Site. Results from exhaust
sampling indicate the system is effective at limited mass removal, in addition to in situ bioremediation.
Performance monitoring will continue, and the next performance groundwater monitoring event and
SVE/AS sampling event is scheduled for December 2023.

1. INTRODUCTION
On behalf of Duke Energy Carolinas, LLC (Duke Energy), ERM NC, Inc. (ERM) has prepared this
Quarterly Groundwater Monitoring and Corrective Action Performance Report for the petroleum
underground storage tank (UST) Incident Number 40750 at Marshall Steam Station in Sherrills Ford,
Catawba County, North Carolina (Figure 1).
1.1 Site Description and Background
1.1.1 Site Location and Current Use
Marshall Steam Station is located at 8320 NC Highway 150 Catawba County Sherrills Ford, North
Carolina. The facility consists of a 1,366-acre parcel currently used as a coal-fired electrical power plant,
which is owned and operated by Duke Energy. The facility’s coal-fired generators are currently active;
however, retirement of the facility is anticipated within the next 10 to 15 years.
The facility is accessed by a paved driveway on the north side of NC-150 and is secured by a fence with
a guard shack. The facility is bounded by a water intake canal and vacant land to the east. Vacant land is
also located to the north. Residential developments and commercial property are located about 0.50 mile
to the west and about 1,700 feet to the south.
Incident Number 40750 is located within the southeastern quadrant of the facility (the Site). The Site is
bounded to the north, west, and east by the power plant and to the east by a water intake canal. The Site
is currently part of the landscaping buffer between the facility building and the water intake canal. The
Site is covered with gravel, and the ground surface slopes to the east towards the intake canal. The Site
layout is depicted in Figure 2.
1.2 Site Hydrogeology
The Site is in Catawba County, North Carolina, within the Piedmont physiographic province. The
Piedmont is a relatively broad strip of land extending from central Alabama across Georgia and the
Carolinas into Virginia. According to the Geologic Map of North Carolina, rock types in the area include
metamorphic schist, phyllite, marble, quartzite, and gneiss, with some granite intrusions (NCGS 1985).
Most bedrock in the Piedmont is overlain with residual soil of varying thickness.
In the immediate area around the former UST, the Site is generally underlain by fill material composed
of tannish brown silt and sandy fill soil. Downgradient of the former UST, the Site is underlain by clayey
sandy gravel fill with large riprap cobbles over layers of silt or silty clay and sand units to a depth of 30
feet below ground surface (bgs).
Topographically, the site elevation is approximately 770 feet. Groundwater elevation is between about
755 and 760 feet. The adjacent intake canal elevation varies but is around 755 feet. Groundwater
generally flows east from the immediate area around the former UST toward the water intake canal.
1.3 Incident Background
During the installation of sewage lines for a critical improvement project, a contractor encountered areas
of suspected petroleum hydrocarbon impacts near a 500-gallon UST located on the southeast portion of
the Marshall Steam Station parcel. According to site personnel, the UST historically contained gasoline
and was abandoned in place.

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
Duke Energy notified the North Carolina Department of Environmental Quality (NCDEQ) UST Section of
these findings on February 3, 2017, and NCDEQ assigned UST Incident No. 40750 to the Site. Duke
Energy removed the 500-gallon UST and excavated approximately 60 tons of petroleum-affected soil.
UST removal, soil abatement, and initial groundwater monitoring activities are discussed in a Limited Site
Assessment Report (Anchor QEA) submitted to NCDEQ dated July 19, 2017. A Comprehensive Site
Assessment Report (Anchor QEA, January 2018) and a Comprehensive Site Assessment Addendum
Report (Anchor QEA, November 2018) were completed at the Site in 2018.
NCDEQ reviewed the findings of LSA and CSA assessment activities and issued a Notice of Regulatory
Requirements (NORR) letter dated December 6, 2018. The NORR specified that Duke Energy implement
monitored natural attenuation (MNA) as a remedial strategy and conduct annual groundwater sampling
from groundwater monitoring wells MW-1 and MW-2 in October of each year. Groundwater monitoring
was completed in 2019 and 2020, in accordance with this requirement.
Following review of data collected in the second half of 2020, NCDEQ UST Section issued another
NORR on November 23, 2020 that requested Duke Energy perform active remediation to decrease
concentrations of constituents in groundwater. In April 2021, ERM prepared a high-level feasibility study
to evaluate remedial alternatives, with the goal of identifying a viable option to reduce the concentrations
of petroleum COCs in the source area, limit the distribution of petroleum hydrocarbons in groundwater,
and protect nearby surface water quality. The biggest obstacles with active remediation implementation at
the Site is the presence of critical subsurface infrastructure, piping and utilities in the source area and
heterogeneous shallow fill with highly variable permeability limiting remedial efficiency.
The feasibility study concluded that air sparge and soil vapor extraction (AS/SVE) was the most
appropriate remedial technology based on site conditions and target constituents. ERM conducted a pilot
test to further evaluate potential efficacy of AS/SVE technology between September and October 2021.
Based on field observations and the results of exhaust and groundwater performance monitoring,
implementation of a full scale AS/SVE remediation system was recommended. Additional details are
provided in the Air Sparge and Soil Vapor Extraction Pilot Test Summary, dated December 30, 2021.
An Acknowledgment of Receipt (in response to the Pilot Test Summary) was issued by NCDEQ on
January 21, 2022. This letter requested quarterly monitoring for a year after implementation of the
AS/SVE system, and semi-annually monitoring thereafter. SVE wells and AS wells proximate to the
former UST location were installed in August 2022 and the AS/SVE system building was delivered to the
Site in June 2023. initial start-up and debugging of the system occurred on June 29, 2023.
There are currently eight groundwater monitoring wells (i.e., MW-1, MW-1D, MW-2, MW-3, MW-4, MW-5,
MW-6, and MW-7) located on-Site associated with the gasoline UST release and subsequent assessment
activities (Table 1). Monitoring was completed in September 2023 and the results are summarized by this
report, representing the first quarterly monitoring event following implementation of the full-scale AS/SVE
system.
1.3.1 Receptors and Potential Receptors
The property upon which the Site is located is owned by Duke Energy. The Site was evaluated for
potential receptors by Anchor QEA, on behalf of Duke Energy, as documented in a UST Removal and
Limited Site Assessment Report dated July 19, 2017. The report found that there are no water supply
wells within a 1,500-foot radius of the Site, and there are no wellhead protection areas in the surrounding
vicinity. The only known receptor is the nearby surface water body, the intake canal associated with Lake
Norman, located approximately 80 feet east of the Site.

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
1.3.2 Historical Data and Remedial Activities.
Initial UST removal and soil abatement activities are discussed in depth in the 2017 Limited Site
Assessment Report by Anchor QEA. Soil analytical results were compared to applicable maximum soil
contaminant concentration levels (MSCCs) and indicated limited residual soil impacts consistent with a
gasoline release. Groundwater analytical results from groundwater monitoring well MW-1 were compared
the groundwater sample results to the standards listed in Title 15A Subchapter 2L .0202 of the North
Carolina Administrative Code (NCAC) (2L standards) and NCDEQ UST Section Gross Contamination
Levels (GCLs). Volatile organic compounds (VOCs) detected above 2L standard in the groundwater
sample collected from MW-1 included benzene, 1,2-dichloroethane, diisopropyl ether, ethylbenzene,
methyl-tert-butyl ether, naphthalene, styrene, toluene, 1,2,4-trimethylbenzene, m&p-xylene, and o-xylene.
Volatile petroleum hydrocarbon (VPH) fractions (aliphatics (C5-C8) and aromatics (C9-C10)) were also
detected above the 2L standard. Constituents detected above the GCLs were limited to benzene and
aliphatics (C5-C8).
Annual groundwater sampling was completed at MW-1 and MW-2 in 2018 and 2019, and completed at
the same wells semi-annually since April 2020. Throughout this time, there has not been visual evidence
of light non-aqueous phase liquids, or sheen, in Site groundwater monitoring wells or on purged
groundwater.
The final groundwater monitoring event prior to startup of the AS/SVE system was on June 6, 2023.
Activities and results are discussed in detail in a June 2023 Groundwater Monitoring Report dated July
25, 2023. Groundwater flow at the Site was to the east, consistent with historical findings. Based on
previously reported Site data, the average hydraulic conductivity (k), as measured at MW-1 and MW-2,
was approximately 0.05 feet per day. Using a hydraulic gradient (i) of 0.0096 feet per foot (between MW-1
and MW-2 on June 6, 2023), k, and an assumed effective porosity (ne) of 10 percent, the groundwater
seepage velocity (v) was calculated as 0.0123 feet per day using the following formula:
𝑣ൌ𝑘𝑖
𝑛௘

where:
𝑣 = groundwater seepage velocity 𝑖 = hydraulic gradient
𝑘 = hydraulic conductivity 𝑛௘ = assumed effective porosity
Groundwater analytical results were compared to 2L Standards, including interim maximum allowable
concentrations (IMACs) as appropriate. They were also compared to intermediate risk criteria, defined in
Title 15A NCAC, Subchapter 2L .0406(2) to include NCDEQ UST Section Gross Contamination Levels
(GCLs). Intermediate risk criteria also includes surface water quality standards (SWQS) listed in Title 15A
NCAC, Subchapter 2B .0200 (2B standards), and the United States Environmental Protection Agency
(USEPA) National Criteria multiplied by a factor of 10 (10xSWQS), since surface water is located within
500 feet of the source area. The most recent petroleum hydrocarbon constituent concentrations
associated with the groundwater samples collected and analyzed from the Site groundwater monitoring
wells relative to the applicable criteria are as follows:
 2L Standards – Ten petroleum-related constituents were detected at concentrations above their
respective 2L Standards in the parent and field duplicate samples collected from MW-1. The sample
collected from MW-1D, MW-2, MW-3, MW-7 did not contain any constituents at concentrations above
their respective 2L Standards.
 10xSWQS – Five constituents were detected above their respective 10xSWQS in the parent and field
duplicate samples collected from MW-1. The samples collected from MW-1D, MW-2, MW-3 and MW-
7 did not contain any constituents at concentrations above their respective 10xSWQS Standards.

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
 GCLs – Benzene is the only constituent detected in groundwater at concentrations above its GCL.
Benzene was only detected above its respective GCL in the groundwater samples (parent and field
duplicate) collected from MW-1.
A table of historical groundwater results is included as Appendix A.

2. REMEDIAL ACTION OBJECTIVES AND TECHNOLOGY DESCRIPTION
2.1 AS/SVE Pilot Test Results
Prior to completing the AS/SVE pilot test, ERM submitted a Notification of Intent (NOI) to Construct or
Operate Injection Wells to the NCDEQ Underground Injection Control (UIC) branch and received a permit
number (permit no. WI0300459). Air injection wells are “permitted by rule” and do not require an
individual permit when constructed in accordance with the rules of 15A NCAC 02C.0200. The notification
covers injection of ambient air for operation of the air sparging wells.
An AS/SVE pilot test was completed in October 2021 to evaluate the efficacy of AS/SVE as both
individual and combined remedial technologies and to determine suitable design and operational criteria
for full-scale implementation. The pilot test was also designed to enhance understanding of Site geologic
conditions and to assess achievable air injection and recovery rates in the vicinity of the former UST.
The pilot test utilized existing groundwater monitoring wells (MW-1D and MW-1) as the temporary air
sparge (AS) and soil vapor extraction (SVE) wells, respectively. Three temporary observation wells were
installed, and two nearby monitoring wells (MW-2 and MW-3) were utilized to evaluate the efficacy of AS
and SVE treatment. The pilot test included the evaluation of the individual and combined effects of AS
and SVE at varying pressures/vacuums and flow rates.
Observations related to piloted SVE operations, including when paired with AS, are summarized below.
 When operating the SVE system alone at a vacuum of at least 8 inches of mercury (in Hg),
effective radius of influence (ROI) was observed in a monitoring point at an approximate distance
of 17 feet.
 Throughout the various phases, the SVE system recovered flows between 80 and 115 cubic feet
per minute (cfm). This flow decreased significantly when inducing vacuums greater than 12 in Hg.
 Notable concentrations of VOCs were recovered in each of the four effluent air samples collected.
During the SVE only phase, a significant increase in VOC concentrations was observed. Followed
by the combined AS/SVE pilot test, the VOC concentrations decreased, which could reflect the
bulk of the readily available VOC vapors had already been captured. Alternatively, this could
reflect a collapsing of the soil or a short circuiting effect as the result of greater vacuums.
Based on the observations during the pilot test, ERM recommended a design flow of 80 cfm per SVE well
at a vacuum of 8-12 in Hg. As a factor of safety, the recommended ROI for design purposes is 15 feet.
Observations related to AS pilot activities, including when paired with SVE, are presented below.
 Increases in oxygen reduction potential (ORP) were observed in wells extending beyond 40 feet
from the AS well. Dissolved oxygen (DO) measurements conflicted with ORP trends and appear
to be the result of faulty equipment.
 Evidence of mounding was not observed. The three observation points remained dry and no
change in the depth of the water was observed in the more distant wells. However, the apparent
rise in water elevation within MW-1 is presumed to be due to short circuiting between the well pair
(MW-1 and MW-1D) rather than true mounding of the water table.
 During the AS only phase, significant increases in VOC vapors were observed in all observation
points. Only a minor effect was apparent in more distant well MW-3, and no effect was apparent
in the most distant well, MW-2.
 After the termination of the pilot test, a favorable impact on groundwater quality was observed. An
immediate decrease in detected VOCs within groundwater at nearby well MW-1, followed by

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
slight rebounding two weeks later. A slight increase in detected VOCs was apparent in a more
distant monitoring well (MW-2) immediately following the pilot test, followed by a slight decrease.
 The injection rate was limited to 2.5 cfm, in conjunction with a pressure range of 22 and 28
pounds per square inch (psi), throughout the combined test to limit mounding. The AS only phase
achieved flows of 5 to 6 cfm, but at the expense of short circuiting between MW-1D and MW-1.
For a full-scale design, ERM recommended a target flow rate of 5 cfm at an expected injection pressure
of 23 to 26 psi. Over time, that pressure is anticipated to decrease as the treatment zone adjusts to
accommodate air sparging. Based on the combined field measurements collected throughout the pilot
test, an effective ROI of 15 feet is assumed.
2.2 Full-Scale System Design and Implementation
The full-scale system consists of 3 SVE wells and 3 AS wells located proximate to the former UST.
Placement of the wells was constrained by an extensive network of underground utilities in vicinity of the
former UST. Prevention of impact to Lake Norman during system operation was also prioritized. Wells
were placed to best capitalize on the anticipated ROI of 15 feet, with consideration to these constraints.
Transfer piping wa installed aboveground to connect AS/SVE wells to a stand-alone building that houses
components of the AS/SVE treatment system. The AS/SVE system includes an air compressor for
sparging and a positive displacement vacuum blower for the vapor extraction. The layout for AS/SVE
wells, transfer piping, and the building are presented in Figure 3. The as-built layout for components
within the standalone building, and a process and instrumentation diagram, are presented as Figures 4
and Figure 5, respectively.
2.2.1 Soil Vapor Extraction (SVE) System Installation
2.2.2 SVE Wells
ERM installed each SVE well to a depth of 20 feet bgs using a hollow stem auger and finished
approximately 1 foot above grade. Each extraction well was constructed with a 4-inch inner diameter,
Type II (single-cased) well with 15 feet of 0.005” slotted Schedule 40 PVC screen and an appropriate
length of solid riser. A washed silica sand filter pack (#1 grade) was used to fill the annular space
between the borehole wall and the SVE well screen. Well construction records are provided as Appendix
B.
2.2.3 SVE Remediation Components
The SVE system primarily consists of 3 SVE wells, a rotary lobe positive displacement vacuum blower, an
air/liquid separation tank with auto-drain transfer pump, and associated filters, piping, and controllers.
Two-inch diameter Schedule 80 polyvinyl chloride (PVC) was used for individual SVE transfer lines to
connect each SVE well to the building that houses system components. Upon entering the system
building, each of the three SVE well transfer lines manifold into a single 4” Schedule 80 PVC header line.
To monitor and control flow from each SVE well, each lateral contains the following:
 Two-inch ball or gate valve;
 Sample collection port;
 Vacuum gauge (0-150” H2O); and
 Flow indicator (tied to system controls for on-site monitoring).

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
The main system header contains a series of sample ports, flow meters, and vacuum gauges for
complete system control and monitoring.
The design airflow rate of up to 80 cfm can be met at each SVE well at an operating vacuum of
approximately 15 in Hg (136 in H2O). With a system comprised of up to 3 SVE wells operating at any
given time, the system is designed to handle 240 cfm at 15 in Hg, accounting for system losses. For
system flexibility, vacuum to each well can be turned off or adjusted individually with a ball or gate valve
to optimize system influence and minimize groundwater inflow. The blower assembly includes an ambient
air dilution valve and a moisture separator. The ambient air intake is equipped with an inlet air
filter/silencer. The moisture separator (approximately 80-gallon) was fitted with three independent level
sensors, a transfer pump, and drain to a 100-gallon polyethylene aboveground storage tank (AST). An in-
line exposed element filter was installed between the separator and the vacuum blower. Blower effluent is
ducted to outside of the building.
2.2.4 Air Emissions
Vapors recovered by the vacuum blower are separated from liquids while passing through an air/moisture
separator, which is capable of withstanding the system design vacuum. The separated vapor exits the
system through a 6-inch aluminum vent stack that runs vertically to the roof. A 6-inch to 4-inch concentric
reducer was positioned at the outlet to increase emission velocity.
2.2.5 Condensate Treatment
Liquids that accumulate within the moisture separation vessel are automatically transferred to a 100-
gallon polyethylene tank, which is designed to handle the expected contaminants of concern. To reduce
the potential for freezing, piping and the polyethylene tank located outside of the building are protected
using insulation and heat tape. The moisture separator and holding tank are fitted with level switches tied
into the blower and compressor motors to prevent overfilling.
2.3 Air Sparge (AS)System
2.3.1 AS Wells
ERM installed each AS well to a depth of 40 feet bgs using a hollow stem auger and finished 1 foot above
grade. Each was constructed as a 2-inch inner diameter, Type II (single-cased) well with 5 feet of 0.010”
slotted schedule 40 PVC screen and an appropriate length of solid riser. Prior to emerging above grade,
each riser transitioned to a high density polyethylene (HDPE) riser. A washed silica sand filter pack (#3
grade) was used to fill the annular space between the borehole wall and the AS well screen. Well
construction records are provided as Appendix B.
2.3.2 AS Remediation Components
The AS system primarily consists of 3 AS wells, a rotary screw air compressor, and associated filters,
piping, and controllers. One-inch diameter SDR-11 HDPE pipe was used for each individual AS lateral
line. Lateral piping located outside the AS/SVE treatment building runs above grade. To monitor and
control flow to each AS well, each lateral contains the following:
 One-inch ball or gate valve;
 Pressure gauge (0-30 psi); and
 Flow indicator (tied into system controls for on-site monitoring).

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
Upon entering the system building, each of the three AS well lateral lines manifolds into a main 2” HDPE
header. The main system header contains flow meters and pressure gauges for system control and
monitoring. The compressor assembly includes an ambient air filter, inline coalescing oil filters, pressure
and temperature indicators, and a pressure relief valve.
The selected compressor meets the design specification pressure of up 5 cfm per AS well (15 cfm total),
at an operating pressure of 23 psi. For system flexibility, pressure and air flow to each well can be turned
off or adjusted individually with a brass, rising-stem gate valve to balance system influence.

September 20, 2023 ERM replaced inline filter, system operation restarted. Adjusted SVE
flow/vacuum to reduce water infiltration (see below for further detail).
October 6, 2023 Final routine biweekly O&M site visit; O&M site visits adjusted to monthly
frequency.

2.4.1 O&M Activities
Activities completed during routine O&M site visits include inspection and replacement of the system’s
filters; inspection of the moisture separation vessel; adjustments to the AS and SVE flow rates to optimize
mass removal; purging of sediment from the air/moisture separator; and testing of the telemetry system
and failsafe controls by manipulating alarm conditions. In addition, routine maintenance of system
components is completed in accordance with manufacturer’s instructions based on hours of operation
and/or visual assessment of condition.
There were a number of adjustments made to the AS/SVE system during the startup period based on
operational feedback. It had been anticipated that minimal condensate would be generated by the air
compressor; however, condensate was found to accumulate in system gauges. Therefore, two auto
drains were installed on the condenser unit, which route condensate to a 5-gallon bucket that is emptied
during maintenance events. In general, the AS system has maintained the target operational flow of 5 cfm
per AS well, although configurations of operation have varied as the system was gradually brought online
and then adjusted further based on moisture intrusion in the SVE system, discussed further below.
The SVE system had two periods of downtime for maintenance. The first period in July was due to
damage to the blower belts likely attributable to a shift in the motor mount during transportation of the
system to the Site. The second period in September was due to saturation of the inline filter, which
indicated moisture/condensate was bypassing the air/moisture separator. Moisture/sediment intrusion has
also interfered with gauges measuring flow from individual SVE wells, and from the system header,
resulting in periods where flow measurements could not be recorded and requiring replacement of
several of these gauges. Water level measurements at SVE-1 indicated potential mounding at that
location, resulting in water influx to the system. When the inline filter was replaced on September 20, a
number of operational adjustments were made to increase efficacy of the air/moisture separator and
reduce influx of water to SVE components. First, operation of well pair AS/SVE-1 was suspended based
on a majority of water originating from that area. Second, vacuum was decreased from 15 in Hg to 10 in
Hg. Flow was reduced at SVE-2 and SVE-3 to approximately 20 cfm and 30 cfm, respectively. The Site
visit on October 3, 2023 indicated that these adjustments were successful in preventing water from
bypassing the air/moisture separator tank, as water was observed within the tank and the downstream

inline filter was found to be dry. Iterative adjustments will continue to maximize removal of the SVE
system, while also maintaining integrity of system components.
No waste products have been produced by the system, to date. Any waste products (e.g., oil waste from
air compressor, etc.) produced in the future will be handled in accordance with applicable regulations.

3. GROUNDWATER REMEDIATION ACTIVITIES AND MONITORING
A key indicator of the effectiveness and progress of an AS/SVE remedial action is the sustained reduction
of contaminant concentrations in groundwater at monitoring wells located within the treatment zone and
downgradient. Prior to system start-up, groundwater was monitored on a semi-annual basis. Following
the start-up of the AS/SVE system, groundwater sampling was conducted at all eight monitoring wells to
monitor for initial effect of the remedial action. Remediation performance monitoring will continue to be
conducted quarterly for a period of one year and will include sampling of five select wells (MW-1, MW-1D,
MW-2, MW-3, and MW-7). Emissions (air samples) will be collected quarterly until such time that
historical data are adequate to predict future mass recovery maximums.
3.1.1 Summary of Groundwater Sampling Activities
The first quarterly monitoring event was completed on September 12-13, 2023. ERM gauged the static
water levels in the eight on-Site groundwater monitoring wells. Following measurement of water levels,
ERM collected groundwater samples from all eight monitoring wells using low-flow groundwater sampling
techniques. Water quality field parameters, including pH, specific conductivity, dissolved oxygen (DO),
oxidation-reduction potential (ORP), turbidity, and temperature are monitored and recorded at
approximate five-minute intervals during groundwater purging (Table 2). Once parameters stabilized,
ERM collected the respective groundwater samples in laboratory-provided containers, placed the
samples on ice in a cooler, and delivered them to SGS North America Inc (SGS) in Orlando, Florida, a
North Carolina-certified laboratory, for analysis of VOCs via Standard Method (SM) 6200B. Groundwater
sampling field forms are provided as Appendix C.
3.1.2 Summary of SVE Emission Sampling Activities
Within the first 8 hours of partial system startup (AS/SVE-1 and AS/SVE-2), an emission air sample was
collected from the SVE/AS system. The air sample was submitted to SGS in Dayton, New Jesey for
laboratory analysis of VOCs using USEPA Method TO-15. At the same time, system flow rate and effluent
temperature measurements were collected for use in estimated mass removal calculations. Additional
samples were similarly collected at intervals noted in Section 2.5, including the first quarterly monitoring
event on September 12, 2023. It should be noted that maintenance downtime of the AS/SVE system
began concurrent with static water level gauging, and prior to collection of groundwater samples. The
downtime was expected to be temporary; however, findings led the downtime to extend throughout
sampling activities.
3.1.3 Summary of Field Activities
ERM did not observe visual evidence of light non-aqueous phase liquids, or sheen, in Site groundwater
monitoring wells or on purged groundwater. Groundwater elevations were from historical survey data and
measured depths to groundwater and are presented on Figure 6, along with the average surface water
elevation data for Lake Norman on June 6, 20231. Historically, groundwater flow at the Site trends to the
east. During the sampling event completed in September 2023, there was no discernible pattern to flow at
the Site. The disruption in flow pattern is likely due to influence of the AS/SVE system on localized
groundwater flow. Groundwater elevations and flow patterns will continue to be monitored for trends.

https://www.duke-energy.com/community/lakes/.

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
A summary of groundwater sample analytical results is presented in Table 3 and the complete laboratory
analytical report is in Appendix D. A map illustrating groundwater analytical data exceeding NC
groundwater quality standards is presented as Figure 7. A summary of historical groundwater analytical
data, and field parameters, is in Appendix A.
Groundwater analytical results were compared to 2L Standards, including IMACs as appropriate. They
were also compared to intermediate risk criteria including 10xSWQS and GCLs. Historically, benzene has
been the only constituent detected in groundwater above its respective GCL at MW-01. The benzene
concentration (305 milligrams per liter [mg/L]) in the sample collected from MW-01 in September 2023
represents a significant reduction when compared to the concentration in the sample collected from the
same location in June 2023 (14,500 mg/L). Additional observations regarding the most recent petroleum
hydrocarbon constituent concentrations associated with the groundwater samples collected and analyzed
from the Site groundwater monitoring wells relative to the applicable criteria are as follows:
 Samples collected from MW-01 contained six constituents detected at concentrations above the 2L
standard, and two constituents detected at concentrations above the 10xSWQS. When compared to
the sample collected from the baseline event in June 2023, there are four fewer constituents detected
above the 2L standard, and three fewer constituents detected above 10xSWQS.
 Constituents were not detected at concentrations above any applicable standards at MW-01D, MW-
02, or MW-04. Historically, samples collected from MW-02 have had periodic exceedances of 2L
standards for two VOCs. Results from MW-01D and MW-04 were consistent with past results. MW-
02 and MW-04 are downgradient monitoring wells.
 The sample collected from MW-03 contained three constituents detected at concentrations above the
2L standard, but below the 10xSWQS. The same three constituents were detected at MW-03 in 2018
at similar concentrations; however, they have not been detected during more recent sampling events.
 The sample collected from MW-05 contained one constituent (methyl tert-butyl ether) detected at
concentrations above the 2L standard, but below the 10xSWQS. This constituent has historically
been detected at this well at similar concentrations.
 Samples collected from MW-06 and MW-07 contained one constituent (vinyl chloride) at
concentrations above both the 2L standard and 10xSWQS. Vinyl Chloride has historically been
detected at MW-06 at similar concentrations; however, it has not typically been detected at MW-07.
Overall, VOC concentrations were found to decrease in the area immediately surrounding the former UST
(MW-01), and concentrations of constituents detected at other wells were generally consistent with past
sampling events. Additional indicators that support efficacy of remedial activities include a notable
increase of DO in groundwater collected at MW-01 and MW-03. Generally, DO is the primary line of
evidence to determine if injected air is reaching a given monitoring point and creating an aerobic
environment to support biodegradation of VOCs. An increase in DO generally results in an associated
increase in ORP; however, this correlation was not uniformly observed during this monitoring period.
Additional sampling events will be necessary to better understand constituent concentration and trends.
Groundwater will continue to be monitored on a quarterly basis through June 2024.
3.1.4 Summary of SVE Emission Sampling Results
A summary of emission sample analytical results is presented in Table 4 and the complete laboratory
analytical report is included in Appendix D. Due to water damage to flow gauges, consistent
measurement of system flow was not possible but, when reliable, is reported on Table 4. Pilot test data
indicated that total recoverable VOCs will not exceed applicable permitted air emission limits. To confirm
these findings, ERM conservatively calculated mass removal of the system using the highest detected
concentration of each constituent across all four sampling events, and the highest recorded flow rate.

www.erm.com Version: 1.0 Project No.: 0698823 Client: Duke Energy October 31, 2023
These calculations are presented on Table 5 and support the findings from the pilot test. It should be
noted that these calculations are not intended to represent an actual estimate of mass removal of the
system, but are being used as a risk management tool to ensure the system is operating within
acceptable emission limits. While mass removal of the system will continue to be tracked through
emission sampling for the purpose of permit compliance, these calculations do not fully capture mass
reduction which is aided by microbial processes in situ.

4. CONCLUSIONS
During the 1st quarterly monitoring event following system installation, performance monitoring
demonstrated a significant decrease in benzene concentrations in the groundwater sample collected at
MW-01, which is positioned adjacent to the former UST and has historically exhibited benzene
concentrations above the GCL. Increases in groundwater dissolved oxygen (DO) concentrations suggest
that injected air is penetrating the treatment zone, which will further promote VOC mass reduction via
biodegradation. Constituents were not detected above applicable regulatory standards in downgradient
monitoring wells, indicating the remedy has not adversely impacted the nearest receptor, which is the
intake canal associated with Lake Norman located approximately 80 feet east of the Site. Results from
exhaust sampling indicate the system is effectively removing VOC mass; however, total removal amounts
are expected to fluctuate as the system is optimized. Performance monitoring will continue, and the next
performance groundwater monitoring event and SVE/AS sampling event is scheduled for December
2023.
