Monitoring Report
NCDOT Maintenance Facility
Newton, North Carolina
H&H Job No. DOT-471

1.0 Executive Summary

On behalf of the North Carolina Department of Transportation (NCDOT), Hart & Hickman, PC
(H&H) has completed this Monitoring Report for the NCDOT Maintenance Facility located at
1302 Prison Camp Road in Newton, Catawba County, North Carolina. The property is currently
occupied by NCDOT and used as an equipment maintenance facility (Figure 1). The North
Carolina Department of Environmental Quality (DEQ) incident number for the site is 27696.
This incident is classified as intermediate-risk due to the presence of free product and/or the
presence of Gross Contamination Level (GCL) exceedances. No active water supply wells are
located within 1,000 feet of the source area (Figure 2). This report documents the results of
groundwater sampling performed by H&H in December 2022 and remediation system operation
and maintenance (O&M) activities for the period of July 2022 through December 2022. A site
map is included as Figure 3.

During the current six-month reporting period, H&H has continued operation of a soil vapor
extraction (SVE), in-well aeration and stripping (IWS), and free product recovery at the site. In
addition, H&H has performed semi-annual groundwater gauging and sampling to evaluate
remediation system performance.

The SVE system was put into operation in 2004 to address soil impacts and promote free product
volatilization and is still in operation. A pneumatic product recovery system was installed by
others in March 2008 to address free product present in source area monitoring and recovery
wells. The recovery system was reconfigured in March 2011 due to diminishing product
thicknesses, and IWS was utilized in recovery wells where trace amounts of free product were
periodically present. In August 2012, a free product recovery pump was reinstalled in MW-6.
Due to the minimal (but persistent) free product in MW-6, H&H removed the product recovery
pump and installed a product recovery absorbent sock in this well in March 2022.

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NC DOT -DOT/DOT-471 Newton GW O&M/Report/January 2023 Monitoring/MO-
6984_27696_CA_MRP_20230220_Monitoring Report.doc
Approximately 0.02 ft of free product was measured in monitoring well MW-6 during the
November 2022 O&M visit. A product recovery absorbent sock was placed in MW-13 in April
2022 due to the presence of approximately 0.03 ft of free product measured in MW-13 during the
April 21, 2022 O&M visit. As shown in Table 1, no free product was present in monitoring well
MW-6 or MW-13 during the December 2022 gauging event. In addition, free product was not
detected in the other site monitoring or recovery wells during the December 2022 gauging event.
Groundwater samples were collected from ten monitoring wells (MW-1, MW-2, MW-3, MW-
14, MW-19, MW-21, MW-25 through MW-27, and MW-29) during the December 2022
sampling event.

Groundwater analytical results from the December 2022 sampling event indicate the presence of
multiple volatile organic compounds (VOCs) including benzene (up to 3,140 µg/L), naphthalene
(up to 625 µg/L), and toluene (up to 6,250 µg/L) in shallow groundwater (Table 2). The 2L
Groundwater Standards for benzene, naphthalene, and toluene are 1, 6, and 600 µg/L,
respectively. December 2022 laboratory analytical results indicate the presence of VOCs above
the 2L Groundwater Standards in monitoring wells MW-2, MW-3, MW-14, and MW-21. In
addition, two VOC detections including 1,2-dibromoethane (EDB) and 1,2-dichloroethane
(DCA) exceeded the DEQ GCLs in monitoring well MW-2. Monitoring well MW-2 was added
to the site’s sampling plan at the request of DEQ following the June 2019 groundwater sampling
event. Free product was previously present in monitoring well MW-2. Considering historical
monitoring data for perimeter monitoring wells, the plume maps indicate that impacted
groundwater is delineated and limited to an area within the subject property boundaries.

Once free phase product has been removed from the site and no groundwater concentrations
exceed GCLs, the site will be eligible for risk–based closure considering the absence of potential
receptors of concern. Due to the minimal free product detected in MW-6 in November 2022 and
recent absence of free product in MW-13, H&H will continue to use absorbent socks and gauge
wells MW-6 and MW-13 for the presence of free product during monthly O&M visits. The
objective of operating the current soil (SVE) and free product removal system (IWS) is the
removal of free product and GCLs. The free product recovery pump in MW-6 will not be used
unless significant free product returns to this well.

2.0 Site History and Characterization

The site is an active NCDOT equipment maintenance facility encompassing approximately
50 acres. Gasoline underground storage tanks (USTs), an oil/water separator and a fuel oil UST
were previously removed from the property. Currently, the NCDOT operates one 15,000-gallon
gasoline UST and one 15,000-gallon diesel UST elsewhere on the property.

In April 2003, NCDOT personnel removed an oil/water separator that received liquids from the
adjacent equipment washhouse. During removal of the separator, impacted soils were observed
and approximately 175 cubic yards of impacted soils were removed. After the soil excavation,
soil impacts remained. NCDOT contracted with H&H to conduct additional soil and
groundwater sampling in the vicinity of the former oil/water separator to delineate the extent of
these impacts. The extent of impacts associated with the former oil/water separator was
delineated, and impacts were reported in the September 2004 Comprehensive Site Assessment
(CSA) (Appendix A).

After detecting gasoline related impacts in groundwater at the former oil/water separator, H&H
discussed potential former UST locations with NCDOT personnel. NCDOT personnel identified
an area located northeast of the old shop building as previously containing a gasoline UST
system that had been removed (Figure 3).

In 2003 and 2004, H&H installed soil borings and monitoring wells in and surrounding the area
that contained the former gasoline UST system. Soil and groundwater impacts including free
product were detected. Soil samples indicated gasoline-type constituents in excess of the
Maximum Soil Contaminant Concentrations (MSCCs). Based on the data collected, the
horizontal and vertical extent of soil impacts was reasonably well delineated (Appendix A).
Generalized historic cross-sections through the former oil/water separator basin and former
gasoline UST area from the CSA are also included in Appendix A. The data indicated that soils
impacted above soil to groundwater MSCCs covered an area of approximately 16,000 ft2 and
extended vertically to the water table (approximately 30 feet below grade).

6984_27696_CA_MRP_20230220_Monitoring Report.doc
Groundwater samples were collected in 2003 from site monitoring and recovery wells and
submitted for laboratory analyses. VOCs, lead, and VPH were detected above groundwater
standards. Benzene was detected in shallow groundwater at concentrations up to 35,000 µg/L,
which exceeded the groundwater standard of 1 µg/L and the GCL of 5,000 µg/L. EDB and DCA
were also detected at concentrations exceeding GCLs. Based on the data collected, the
horizontal and vertical extent of groundwater impacts was reasonably well delineated.

Based on the presence of free product, Aggressive Fluid Vapor Recovery (AFVR) and Mobile
Multi-Phase Extraction (MMPE) events were conducted. Due to the persistence of the free
product, NCDOT directed H&H to install an interim soil vapor extraction (SVE) remediation
system to remove free product and treat source area soils. The SVE system was installed in 2004
and is still in operation. In March 2008, a free product recovery system utilizing six pneumatic
free product only recovery pumps was designed/installed by others to accelerate the removal of
free product from the site. The product recovery system was in operation until March 2011
when it was removed because free product was no longer being effectively removed. In March
2011, H&H installed an in-well aeration system (IWS) to assist with removal of the remaining
free product. In August 2012, a free product pump was re-installed in MW-6 due to the
sustained accumulation of free product in this well. Currently, SVE, IWS, and free product
recovery from MW-6 are being used to remediate the site.

In a Notice of Regulatory Requirements letter dated February 15, 2013, DEQ requested sampling
of site monitoring wells MW-1, MW-1D, MW-3, MW-5, MW-9, MW-14 through MW-19, MW-
21, MW-22 and MW-25 through MW-29 on a semi-annual basis. This sampling schedule was
started June 2013 and followed through December 2015.

Following a January 26, 2016 meeting attended by DEQ, NCDOT and H&H, DEQ approved in a
February 18, 2016 Acknowledgement of Report Receipt letter the removal of monitoring wells
MW-1, MW-1D, MW-5, MW-9, MW-15 through MW-18, MW-22 and MW-28 from the
required sampling schedule. During the same DEQ meeting, it was decided that perimeter
monitoring wells MW-7, MW-8, MW-20, MW-23, MW-24, MW-30, MW-31, MW-32 and
recovery well RW-11 (located outside the source area) would be permanently abandoned. In

6984_27696_CA_MRP_20230220_Monitoring Report.doc
addition, DEQ approved a 96-hour MMPE event (following remediation well
scrubbing/cleaning) that would be performed to address source area free product in the vicinity
of MW-6.

The well abandonments noted above were performed by Geologic Exploration Inc. (GEX) in
July 2016. Each of the abandoned wells were tremie grouted with a portland bentonite slurry to
land surface.

On July 15, 2016, GEX performed well scrubbing activities on eight wells (MW-6, MW-11,
MW-13, RW-2, RW-4 through RW-6 and RW-12) in preparation for a scheduled MMPE event.
The MMPE event was proposed to determine if the small amounts of remaining free product
could be removed by a final MMPE event. The well screens at proposed suction and product
monitoring well locations were scrubbed with a stainless-steel brush to remove possible
biological growth or mineral deposits resulting from operation of the IWS system that could
interfere with free product recovery.

H&H contracted Advanced Environmental Services to perform a 96-hour MMPE event between
July 18 and July 22, 2016. The MMPE event was performed on source area wells MW-6, RW-2,
RW-4, RW-6 and RW-12 that have historically contained free product. Approximately 3,563
gallons of impacted groundwater were recovered during the MMPE event. Of the 3,563 gallons
of total fluid, no measureable free product was recovered in the liquid phase (although a
petroleum sheen was observed) and only approximately 1.82 gallons (11.02 pounds) of product
were recovered in the vapor phase. Although no free product was detected in any of the site
wells immediately following the MMPE event, the site was regauged after a period of two weeks
(August 5, 2016) and small amounts of free product (0.01 - 0.05 ft) were observed in MW-6,
RW-2, RW-5, and RW-12.

The remediation systems were restarted following the August 5, 2016 gauging event and are
currently in operation.

On June 9, 2020 damaged monitoring well pads were repaired/replaced at the site. H&H

6984_27696_CA_MRP_20230220_Monitoring Report.doc
contracted with GEX to replace monitoring well pads on wells MW-1, MW-1D, MW-2, MW-4,
MW-16, MW-17, MW-21, and MW-22. Damaged well pads were removed and replaced with
new manholes and poured concrete pads. Because the well casing for MW-2 was repaired, H&H
resurveyed the top of casing (TOC) for this well. Based on the survey measurements the TOC is
0.32 ft higher than the previous casing elevation. The TOC elevation for MW-2 has been
updated in Table 1 of this report.

Because the monitoring well casing in MW-5 was damaged and could not be repaired, this well
was abandoned on June 9, 2020. Monitoring well MW-5 was abandoned using neat cement
grout in accordance with 15A NCAC 2C Well Construction Standards. The well pad was
removed and PVC well casing was cut off below ground surface. The removed well pad location
was then filled with top soil to match the existing ground surface.

On October 19, 2021 additional damaged monitoring well pads were repaired/replaced at the
site. H&H contracted with Saedacco, Inc. to replace monitoring well pads on wells MW-15,
MW-19, MW-22, and MW-26. Damaged well pads were removed and replaced with new
manholes and poured concrete pads.

3.0 Receptor Information

3.1 Water Supply Wells

No active water supply wells are located within 1,000 feet of the source area. WSW-1, located
within 250 feet of the source area, was abandoned permanently on October 10, 2005. WSW-2,
located on the subject site approximately 670 feet from the source area, is out of service,
permanently sealed with a welded cap, and buried below grade. WSW-16 (located
approximately 600 feet from the source area at the Department of Corrections facility at
1347 Prison Camp Road), is out of service, permanently sealed with a four-inch thick concrete
pad, and is also buried below grade. WSW-5 is approximately 1,065 feet from the source area
and based on tenant interviews, is used for irrigation only. Therefore, no water supply wells are
located within 1,000 feet of the source area. Based on this information, the site was downgraded
in 2008 from a high risk to an intermediate risk site. Information on the supply wells within
1,000 ft of the source area are summarized in Table 3, and well locations are shown on Figure 2.

To address an email from Ms. Megen McBride of Catawba County Environmental Health in
response to our August 2018 monitoring report, H&H conducted research and a site visit to find
more information on sealed wells WSW-2 and WSW-16. H&H interviewed site personnel,
checked with NC DEQ Mooresville Division of Water Resources, checked with the NC DOT
archivist and visited the Site and prison property to observe the previously reported well
locations. H&H did not find additional information or observe surface evidence of these two out
of service water supply wells.

3.2 Surface Water

The closest surface water feature to the subject property is Bills Branch. Bills Branch is located
to the north and west of the subject site. The closest point of Bills Branch to the source area is
approximately 2,000 ft to the north (Figure 1). Bills Branch discharges to Clark Creek
approximately 7,500 ft southwest of the source area.

3.3 Property Owners and Area Land Use

The subject site is used as a maintenance and equipment facility for NCDOT. A fence and
lockable gates limit access to the site. The land use in the vicinity of the subject site is mixed
manufacturing, commercial, residential, and undeveloped/agricultural. The zoning of the subject
site and most properties along Prison Camp Road is Manufacturing (M-1) with residential zoned
areas to the southwest, south, and northeast. There are three residences located approximately
1,100 ft to the southwest, south, and northeast of the source areas. Adjacent property owners and
uses are summarized in Table 4 and Figure 4.

4.0 Geology and Hydrogeology

4.1 Regional Geology and Hydrogeology

The subject property is located within the Piedmont Physiographic Province of North Carolina
(Piedmont). The Piedmont is generally characterized by a thick mantle of weathered residuum
over fractured crystalline and metamorphic rock. The Piedmont region consists of low, rounded
hills and long, rolling, northeast-southwest trending ridges. The region is underlain by bedrock
of Precambrian and Paleozoic age consisting of igneous and metamorphosed igneous and
sedimentary rocks, including granite, gneiss, schist, quartzite, slate, marble and phyllite.
According to the Geologic Map of North Carolina (1985), the bedrock in the vicinity of the
subject site is composed of amphibolite and biotite gneiss.

In the Piedmont, the bedrock is overlain by a mantle of weathered rock termed saprolite or
residuum. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of
rock fragments. Due to the range of parent rock types and their variable susceptibility to
weathering, the saprolite ranges widely in color, texture, and thickness. Generally, the saprolite
is thickest near interstream divides and thins toward stream beds. In profile, the saprolite
normally grades from clayey soils near the land surface to highly weathered rock above
competent bedrock.

The occurrence and movement of groundwater in the Piedmont is within two separate but
interconnected water-bearing zones. A shallow water-bearing zone occurs within the saprolite,
and a deeper water-bearing zone occurs within the underlying bedrock.

Groundwater in the shallow saprolite zone occurs in the interstitial pore spaces between the
grains comprising the saprolitic soils, and is typically under water table or unconfined
conditions. Ground water movement is generally lateral from recharge areas to small streams
that serve as localized discharge points.

The occurrence and movement of groundwater in the underlying water-bearing zone within the
crystalline bedrock is controlled by secondary joints, fractures, and faults within the bedrock.

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/NC DOT -DOT/DOT-471 Newton GW O&M/Report/January 2023 Monitoring/MO-
6984_27696_CA_MRP_20230220_Monitoring Report.doc
On a regional scale, the direction of groundwater flow is typically from uplands to major streams
and ground water sinks. The saprolite has a higher porosity than the bedrock and serves as a
reservoir that supplies water to a network of fractures in the bedrock.

4.2 Site Geology and Hydrogeology

In general, soils encountered in the vicinity of the former oil/water separator and gasoline UST
areas consist of sandy to silty clay fill soils from the surface to depths of 5 to 10 ft. The depth to
groundwater is approximately 25 to 30 ft below grade in the source area. The fill soils are
generally underlain by residual soils consisting of sandy silts to a depth of approximately 60 ft,
where partially weathered rock (PWR) was encountered. Bedrock was not encountered in
H&H’s borings, but bedrock is expected just underneath PWR. Logs of borings conducted by
H&H at the site are included in Appendix B. Site geologic cross-sections with December 2022
benzene groundwater concentrations and isoconcentration contours are presented as Figures 5
and 6.

Hydraulic conductivity tests (slug tests) were performed on monitoring wells MW-6, MW-7, and
MW-9 on November 5, 2003. A slug of water was removed from each well using a 36-inch
bailer and water levels were monitored over time. The slug test data were analyzed using the
method of Bouwer and Rice. The test results indicate hydraulic conductivity at the site ranges
from approximately 0.005 ft/day to 0.35 ft/day. The geometric mean hydraulic conductivity is
0.06 ft/day (2 x 10-5 cm/sec). Based on the site horizontal gradient of 0.01 ft/ft, hydraulic
conductivity of 0.06 ft/day, and assumed porosity of 0.25, the ground water velocity is estimated
to be only 1 ft/yr. Slug tests can sometimes result in lower aquifer hydraulic conductivity
estimates because they measure only a small portion of the aquifer in the vicinity of the tested
monitoring wells. Based on the plume extent and number of years of site UST operations, the
actual ground water velocity at the site appears to exceed 1 ft/yr.

5.0 Groundwater Sampling

5.1 Water Levels and Free Product

On December 20, 2022, H&H gauged water levels in the site monitoring wells. Monitoring well
gauging and top of casing (TOC) data are included in Table 1. A shallow groundwater
potentiometric map, along with estimated water table elevations, is shown on Figure 7. Based on
the December 2022 groundwater gauging event, the groundwater flow direction is generally to
the northwest, which is consistent with prior data. Historical groundwater elevation data are
included in Appendix C.

During the December 20, 2022, gauging event, no free product was detected in source area
monitoring well MW-6 and nearby monitoring well MW-13. In addition, free product was not
detected in other monitoring or recovery wells at the site. The last time that free product was
detected was in November 2022. Approximately 0.02 ft of free product was measured in MW-6
during remediation system O&M activities on November 23, 2022. The historical product plume
for June 7, 2004 measured prior to the initial AFVR event is shown on Figure 8. The data show
that the free product has greatly diminished due to the active remediation and the use of
absorbent socks.

5.2 Monitoring Well Analytical Data

In a DEQ Acknowledgement of Report Receipt letter dated February 18, 2016, NCDOT was
given permission to remove previously sampled wells MW-1, MW-1D, MW-5, MW-9, MW-15
through MW-18, MW-22 and MW-28 from the semi-annual sampling schedule. Monitoring
well MW-2 was added to the site’s sampling plan at the request of DEQ following the June 2019
groundwater sampling event and subsequent monitoring report. On February 13, 2020, DEQ
requested that MW-1 also be added to the sampling schedule. As a result, ten monitoring wells
MW-1, MW-2, MW-3, MW-14, MW-19, MW-21, MW-25 through MW-27, and MW-29 are to
be sampled on a semi-annual basis.

Prior to sampling the above-mentioned monitoring wells, dissolved oxygen readings were

6984_27696_CA_MRP_20230220_Monitoring Report.doc
obtained, and the monitoring wells were purged until pH, temperature, and conductivity
stabilized. Groundwater samples were then collected using dedicated polyethylene bailers,
poured into laboratory-supplied containers, marked with identifying labels, and placed in an iced
cooler for shipment under chain-of-custody to a certified laboratory for analysis. Groundwater
samples were analyzed for VOCs by Standard Method 6200B.

Petroleum-related impacts were detected above NC 2L groundwater standards in monitoring
wells MW-2, MW-3, MW-14, and MW-21 (Table 2). Petroleum-impacted groundwater extends
from the former UST basin primarily to the west, but also slightly to the north. The highest
concentrations were detected in monitoring well MW-2, which is located downgradient of the
historical free product area. Two VOC detections in monitoring well MW-2 exceeded their
respective GCLs and included EDB (250 µg/L) and 1,2-DCA (425 µg/L). No other VOCs were
detected above GCLs in the wells sampled during the December 2022 sampling event. No
petroleum-related impacts were previously detected in well MW-1D, a Type-III vertical extent
monitoring well. Based on the multiple sampling events showing no impacts in this deeper well,
it was removed from the sampling schedule.

Isoconcentration maps of BTEX, benzene, and xylenes in shallow monitoring wells are included
as Figures 9 through 11, respectively. The GCL detections in MW-2 are depicted on Figure 12.
The plume maps indicate that impacted groundwater is delineated and limited to an area within
the subject property boundaries. Groundwater sampling results are summarized in Table 2, and
the analytical laboratory report is attached as Appendix D. Historical groundwater sampling
results obtained by H&H and others are provided in Appendix C for comparison.

To further evaluate groundwater conditions at the site, H&H collected dissolved oxygen (DO)
and other geochemical parameters in each monitoring well (Table 5). DO is used by microbes as
an electron acceptor in the biodegradation of petroleum hydrocarbons. Biodegradation of
petroleum compounds most efficiently occurs under aerobic conditions (DO concentrations
greater than 1 mg/L), but can also occur under anaerobic conditions (DO concentrations less than
1 mg/L). During the December 2022 groundwater sampling event, DO in the shallow
monitoring wells ranged from 0.09 mg/L (MW-13) to 8.45 mg/L (MW-19). Generally, lower

6984_27696_CA_MRP_20230220_Monitoring Report.doc
DO concentrations were observed in source area and impacted wells as compared to non-
impacted wells. These data suggest aerobic biodegradation is occurring in the plume. A
summary of DO concentrations measured during the December 2022 sampling event is provided
in Table 5. Historical DO data are included in Appendix C.

5.3 Groundwater Concentration Trends

Gasoline constituent concentrations outside the source area have decreased significantly over
time (Table 2 and Appendix C). For example, monitoring well MW-21 has indicated a decrease
in benzene from a high of 8,000 µg/L in August 2007 to 1.5 µg/L in November 2019. However,
concentrations of benzene in MW-21 have more recently increased up to 440 µg/L (June 2021)
since the November 2019 sampling event. Benzene was detected at a concentration of 312 µg/L
in MW-21 during the December 2022 sampling event. Benzene concentrations in MW-3 have
decreased form a high of 2,290 µg/L in August 2007 to 108 µg/L in December 2022. Benzene
was detected at a concentration of 3,140 µg/L in downgradient monitoring well MW-2 in
December 2022 continuing a decreasing trend from a high of 43,200 µg/L in August 2007.
Benzene concentrations in near source area monitoring well MW-14 have decreased from 3,990
µg/L in August 2007 to 1.64 µg/L in December 2022, and benzene concentrations in monitoring
well MW-25 have decreased from 862 µg/L in August 2007 to below method detection limits in
December 2022. Benzene concentration trend graphs are included in Appendix E. Although there
have been significant decreases in benzene concentrations over time, the benzene concentrations
remain relatively high in certain source area wells.

Concentrations of benzene, EDB and 1,2-DCA have historically been detected in MW-2 above
their respective GCLs. As noted above, concentrations of EDB (250 µg/L) and 1,2-DCA (425
µg/L) were detected above their respective GCLs of 50 µg/L and 400 µg/L, respectively, in
December 2022. The highest concentrations of EDB (1,100 µg/L) and 1,2-DCA (2,800 µg/L)
were detected in MW-2 in February 2008. Benzene was detected at a concentration of 3,140
µg/L in MW-2 below it’s GCL of 5,000 µg/L in December 2022. Concentrations of benzene
have decreased in MW-2 from a high of 43,200 µg/L in August 2007. In general, the
concentrations of EDB, 1,2-DCA, and benzene are decreasing over time. An EDB and 1,2-DCA

6.0 Remediation System Operation

6.1 Soil Vapor Extraction / In-Well Aeration System

H&H monitors the performance of the SVE/IWS system by conducting monthly O&M visits.
The SVE system utilizes a 4 hp Gast regenerative blower and extracts soil gas from monitoring
wells and recovery wells in the vicinity of the former UST basin (Figure 13). The SVE system
operational status, number of hours of operation, inlet vacuum, airflow, and off-gas PID readings
are recorded during each site visit (Table 6).

The SVE system ran without issue during the reporting period. The IWS system air compressor
was running during the July 2022 O&M visit, but was not operating during the August 2022 visit
due to a bad compressor pump/motor. H&H made attempts to repair the compressor during the
reporting period. The compressor was restarted during the November 2022 O&M visit.
However, the compressor tripped the electrical circuit and could not be restarted during the
December 2022 visit due to the bad pump/motor. H&H is currently seeking a replacement
compressor for the IWS system.

During the March 24, 2022 O&M visit, SVE wells RW-2, RW-5, RW-12, and MW-13 were
closed to increase SVE system performance in the western remediation well field because GCLs
in MW-2 are situated downgradient of this area (Figure 13). When operating, IWS is being
performed on select wells in the eastern and western remediation fields. The compressor is
capable of producing sufficient airflow for approximately three to four IWS wells at a time in
addition to operating the product recovery pump. During the March 2022 O&M visit, the IWS
was adjusted to only operate in wells RW-4, RW-9, MW-11 and MW-12 to increase system
performance the western well field (Figure 13).

IWS system checks include review of operational status, air compressor condition, air injection
pressures, and select well gauging to monitor the performance of the IWS/SVE system and the
removal of free product from the site (see Tables 6, 7 and 8 and historical data in Appendix C).
As noted above the IWS is not currently not operating.

6984_27696_CA_MRP_20230220_Monitoring Report.doc

Monitoring wells MW-13, MW-15 and MW-16 were gauged during each monthly O&M visit for
the presence of free product that may have migrated downgradient. An O&M log sheet is
completed during each site visit and kept in a bound folder. Recent remediation system
operational logs are provided in Appendix F. Approximately 0.04 ft and 0.03 ft of free product
was measured in monitoring well MW-13 during the January 2022 and April 2022 O&M visits,
respectively. Due to the presence of free product, a product recovery absorbent sock was placed
in MW-13 in April 2022. No free product was measured in MW-13 during the current reporting
period. If no free product is measured in MW-13 during the March 2023 O&M visit, H&H will
remove the absorbent sock and continue to monitoring MW-13 for the presence of free product
during the remainder of the reporting period. No free product has been detected in monitoring
wells MW-15 or MW-16 to date.

Off-gas samples are collected from the SVE exhaust on a semi-annual basis for laboratory
analysis using EPA Method EPA-18 to determine estimated off-gas removal rates (Tables 6 and
9). Using the air sample data collected on December 20, 2022, as an average value for the
period, <168 lbs of Total Recoverable Petroleum Hydrocarbons (TRPH) were removed during
the 180 days of the operating period from June 23, 2022, to December 20, 2022, (see Table 10).
PID readings are collected on a monthly basis during system O&M events and ranged from 15.6
ppm to 18.8 ppm between July 2022 and December 2022. Since the start of remediation, an
estimated 6,554.2 lbs (approximately 1,060 gallons of equivalent as gasoline) of petroleum have
been removed. However, the removal has decreased in recent years. The recent off-gas
laboratory analytical data report is provided in Appendix G. Please note that the units of mg/m3
in the laboratory report were used for calculations, and TRPH was standardized to benzene by
the laboratory.

6.2 Free Product Recovery System Operation and Progress

The free product recovery system for MW-6 includes a 55-gallon product recovery tank, which
is grounded and equipped with a high level shut-off switch and galvanized steel vent pipe. Air
line is run from a QED C-100 controller inside the remediation building to MW-6 to provide air
for the pneumatic product recovery pump. A product return line is installed within a protective
2” PVC secondary containment chase from MW-6 to the product recovery tank (Figure 14). A
product only recovery pump (QED model SPG2 AutoGenieTM) is utilized for product recovery.

The product recovery pump in MW-6 was started on August 31, 2012. Since start-up of the
product recovery pump on August 31, 2012, approximately 50.7 gallons of free product have
been recovered from MW-6 (Table 11). As noted above, the compressor which also operated the
free product recovery pump is not currently operating due to a bad pump/motor. However, a free
product sock is currently in MW-6 as discussed below. As such, the compressor is not needed for
the free product recovery pump at this time.

Due to the minimal (but persistent) product in MW-6, H&H removed the product recovery pump
and installed a product recovery absorbent sock in this well during the March 24, 2022 O&M
visit. As noted above, a product recovery absorbent sock was placed in MW-13 on April 21,
2022. Approximately 0.02 ft of free product was measured in MW-6 during remediation system
O&M activities on November 23, 2022. During the December 20, 2022 gauging event, no free
product was present in MW-6 or MW-13. The absorbent socks appear to be removing the
minimal free product in MW-6 and MW-13. Comparing December 2022 product thickness
measurements to June 2004 measurements indicates the presence of free product is diminishing
and the impacted area has been reduced significantly (Figure 8).

7.0 Monitoring and Reporting

To evaluate remedial activities, the following monitoring program is being followed:

 Perform remediation system inspections and maintenance monthly (or as required). This
includes recording vacuum readings, off-gas PID readings, free product recovered and
monitoring well product thickness.

 Semi-annual analysis of SVE off-gas for VOCs (including benzene, ethylbenzene,
toluene, xylenes, and TRPH) by EPA Method 18 to estimate mass removal. Based on the
analytical results of recent sampling events, the SVE off-gas sample collection may no
longer be necessary.

 Semi-annual groundwater sampling from select site monitoring wells for analysis of
VOCs by EPA Method 6200B.

 Preparation of semi-annual monitoring reports containing the above information.

8.0 Conclusions and Certification

Gasoline related impacts including free product are present at the NCDOT maintenance facility
in Newton due to a former UST system release. The NCDOT maintenance facility ranks as an
intermediate risk site based on the intermittent presence of free product in monitoring wells MW-
6 and MW-13, and GCLs in MW-2.

During the December 2022 groundwater sampling event, petroleum-related impacts were
detected above groundwater standards in monitoring wells MW-2, MW-3, MW-14, and MW-21.
No free product was identified in monitoring wells during the December 2022 gauging event.
Petroleum-impacted groundwater extends from the former UST basin primarily to the west. The
highest benzene concentration was detected in monitoring well MW-2, which is located
downgradient of the source area. Benzene was detected in MW-2 at a concentration of 3,140
µg/L. DCA and EDB concentrations exceeded GCLs in MW-2. Overall, the petroleum VOC
plume extent has decreased since 2007. December 2022 sampling results indicate the
groundwater plume is not significantly migrating and is located within the NCDOT property
boundaries.

SVE off-gas analytical results did not indicate detectable levels in December 2022. However,
monthly PID monitoring of the blower off-gas verify continued contamination removal by the
combination SVE/IWS remediation system. In addition, due to the recovery of approximately 50
gallons of free product since 2012 utilizing the recovery pump installed in MW-6, the decrease in
both the number of monitor and recovery wells containing free product (including the use of
product recovery socks), and the diminishing product thickness, H&H believes the remediation
system is operating as designed. H&H will continue to direct the SVE vacuum to the western
recovery well field since the GCLs in MW-2 are situated downgradient of this area. H&H is
seeking a replacement air compressor for continued IWS near the source area. The product
recovery absorbent sock will remain in MW-6. The product recovery sock will be removed from
MW-13 if no free product is detected in March 2023 and H&H will monitor MW-13 for the
presence of free product for the remainder of the reporting period. Meeting GCLs may require
the addition of air sparging or another technology. H&H recommends air sparging in the source

area (potentially outside of the area of historical free product). The next semi-annual sampling
event is scheduled to take place in June 2023, and a Monitoring Report will be prepared in July
2023.
