B. EXECUTIVE SUMMARY
The purpose of this report is to present the current status of groundwater quality at the Former Ward’s Citgo
site (Incident No. 17850) that is located at 10236 W R Latham Road (Intersection of Highway 211 and
Highway 701 Bypass) in Clarkton, Bladen County, North Carolina (Exhibit 1). Terracon completed this
report to summarize the findings of assessment activities performed at the site on November 14, 2019.

Six USTs were removed in November 1994 and a seventh UST was removed in 2007. In July 2015,
Terracon supervised the removal of three additional USTs and the abandonment-in-place of one additional
UST. Several rounds of assessment have been performed at the site which included the installation of a
groundwater monitoring well network, soil assessments, contaminated soil removal and groundwater
remediation events. Prior assessment results revealed concentrations of petroleum compounds in soil
above their respective soil-to-groundwater Maximum Soil Contaminant Concentrations (MSCCs) and in
groundwater above the applicable 2L Standards. Free product was observed infiltrating the excavation
during the tank closures and has been documented in at least one of the on-site monitoring wells (MW-1).

At the direction of the NCDEQ, Terracon mobilized to the site on November 14, 2019 to gauge monitoring
well MW-1 for free product and to collect groundwater samples from the other nine existing groundwater
monitoring wells associated with the incident (MW-3, MW-4, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11
and MW-12). Two of the groundwater monitoring wells (MW-10 and MW-11) have been installed off-site
on adjoining property to the east across WR Latham Street (701 Bypass). Monitoring wells MW-2 (and
MW-2R, a replacement well for MW-2) and MW-5 have not been able to be located during Terracon’s
involvement with this project and are presumed destroyed. Terracon formerly sampled MW-18, a well
installed on the site for an offsite UST incident investigation, from 2014 through 2016. During the 2018
sampling event, Terracon could not locate MW-18 and it was later documented that this well has been
abandoned as the offsite incident has been closed by NCDEQ’s Fayetteville Regional Office.

A multi-mobile phase extraction (MMPE) was performed on this site in June 2019.

Free product was observed in monitoring well MW-1, so a groundwater sample was not collected from this
well. No free product was observed in the other wells associated with this incident.

Groundwater flow was documented to be generally towards the south-southeast during the November 2019
sampling event.

Groundwater samples collected on November 14, 2019 were submitted for laboratory analysis of volatile
organic compounds (VOCs) by EPA Standard Method 6200B with methyl-tert-butyl ether (MTBE), ethylene
dibromide (EDB), and isopropyl ether (IPE).

Monitoring well MW-1 was identified to contain approximately 0.04 feet (or approximately 0.5 inches) of
free product during the November 2019 site visit. The oil-water interface meter used during the November
2019 sampling event did not detect free product in MW-1. However; Terracon verified the presence of the
free product using a disposable bailer. The bailer and free product found in MW-1 on November 14, 2019
is depicted on the cover photo of this report with an additional photo of the free product in MW-1 located in
the photo log in Appendix B.

Based on information obtained during the completion of the monitoring activities performed in November
2019, Terracon provides the following findings and conclusions:
Free product was observed in monitoring well MW-1 at an apparent thickness approximately 0.04 feet
(or approximately 0.5 inches). The free product thickness level in MW-1 has decreased significantly
since the March 2019 gauging event and after a Multi Mobile Phase Extraction (MMPE) event that was
performed at the site in June 2019.
Benzene has historically been detected at a concentration exceeding its Gross Contamination Level
(GCL) in onsite monitoring well (MW-12). However, during the recent groundwater sampling event in
November 2019, the benzene level at MW-12 was at 4,120 micrograms per liter (µg/l) and below the
NCDEQ established GCL of 5,000 µg/l for benzene. Historically, benzene exceeding GCLs have also
been detected in monitoring well MW-9. The benzene level in MW-9 was detected at 3,110 µg/l in
November 2019 and below the NCDEQ established GCL for benzene. The benzene level in monitoring
well MW-9 has increased significantly since its sampling event in March 2019 (was 619 µg/l at that time).
The benzene level in monitoring well MW-12 decreased since its initial sampling event in January 2016.
The MMPE was performed on both MW-9 and MW-12 in June 2019.
The groundwater samples collected from monitoring wells MW-3, MW-4, MW-6, MW-8, MW-9 and MW-
12 contained at least one target petroleum constituent that exceed the applicable 2L Standard.
Concentrations of target contaminants in these wells generally appear to be stable or decreasing.
The groundwater samples collected from monitoring wells MW-7, MW-10 and MW-11 were analyzed to
contain at least one target petroleum constituent above the laboratory’s reportable limits, but below the
2L Standards. Concentrations in these three wells have been less than the 2L Standards for four or
more monitoring events.
The lateral extent of groundwater impact generally appears to be defined by the existing monitoring well
network.
The general groundwater flow direction appears to be towards the south and southeast.

A receptor survey was not performed during the March 2019 event. A receptor survey update was most
recently performed as part of the January 2018 services.
The 2018 receptor survey confirmed the presence of a potential inactive non-potable water supply well
previously identified as PWSW-1 located approximately 530’ east of the source area (the former UST
basin).
The property owner where a prior potential water supply well (PWSW-2) was identified to be located
indicated that no water supply well is present at this property and that this property is connected to
municipal water.
Terracon also attempted to contact the property owner where potential supply well PWSW-3 was
previously identified. At the issuance of this report, a response has not been received from this property
owner.
A municipal water supply well (Well # 1) is located approximately 1,150 feet northeast of the source area
and a second water supply well (Well # 3) is located approximately 1,350 feet southeast of the source
area. Well #1 and Well #3 are considered to be within wellhead protection areas. Municipal water is
reportedly utilized at the site and within the Town of Clarkton.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to present the current status of groundwater quality at the former Ward’s Citgo
site. Terracon completed this report to summarize the findings of assessment activities performed on
November 14, 2019 at the former Ward’s Citgo located at 10236 W R Latham Road (Intersection of Highway
211 and Highway 701 Bypass) in Clarkton, Bladen County, North Carolina (Figure 1). This Monitoring
Report was prepared for the site in response to a request by the Incident Manager, Mr. Mark Petermann
with the NCDEQ Division of Waste Management, State Lead Program.

The Monitoring 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, under the supervision of Mr. Carl F. Bonner, a North Carolina registered Professional
Engineer (NC Registration No. 16252).

C.1 Site Setting
The site is comprised of approximately 0.5 acres of commercial property. The property contains an
approximate 1,600 square foot (sf) building that is currently being utilized as a car washing and car detailing
facility; one approximately 200 sf restaurant building and one approximately 200 sf storage building. The
site is further improved with a canopy above inactive dispenser pumps, a canopy above a picnic table area,
a canopy next to the restaurant and asphalt, gravel and concrete drives/parking areas. The site is depicted
in Exhibit 2.

The adjacent property to the north consists of a warehouse and a building that sells ice. Adjoining property
to the east is W R Latham Road with a restaurant (the former Clarkton BP gas station) and a grassed lot
across the road. The adjoining property to the south is the intersection of W R Latham Road and West
Green Street (Hwy 211) with a Scotchman gas station that contains a Subway restaurant across the

intersection. Adjoining property to the southwest is West Green Street with TS Mart gas station/Harvey’s
Diner and a Dollar General across the road.

C.2 Release Summary
The site has had two separate release incidents. A release was discovered at the site in September 1994
(Incident No. 13245) during the closure of gasoline, diesel and kerosene USTs formerly utilized onsite.
Petroleum soil contamination and free product were reportedly observed during the 1994 tank closure
activities. The former tank basins where the USTs were removed in 1994 are referred within this report as
“Pit A” and Pit B.”

A second release was discovered on the site in August 1997 (Incident No. 17850) during a site check for a
12,000-gallon, multi-compartment gasoline UST that was reportedly utilized onsite until the early 2000s and
was closed by removal in 2007. Incident 13245 was combined with Incident 17850 in 1998. The release
from the 12,000-gallon gasoline UST was from leaks in the fiberglass product supply lines. Petroleum soil
contamination above NCDEQ Action Levels and free product were also observed during the 2007 tank
closure activities. The 12,000-gallon UST was located within “Pit B.”

Terracon supervised the removal of three 4,000-gallon gasoline USTs and the abandonment-in-place of
one 4,000-gallon gasoline UST in June 2015. These four USTs were removed/abandoned under Incident
number 17850. The former dispenser pumps and product lines were also removed during the June 2015
tank removal/abandonment services. Contaminated soil removal activities were also conducted in the area
of the former tank pit and underneath the canopy where the dispenser pumps and product lines formerly
were located.

A summary of UST removal and subsequent assessment activities at the site is discussed in the following
section of the report.

An off-site release (Incident No. 29290) has been documented on eastern adjoining property across W R
Latham Street (currently the site of the Blue Moon Grille and formerly occupied by Clarkton BP). It is our
understanding that Clarkton BP was formerly a gas station and the leaking tank incident associated with
this facility was recently closed by NCDEQ’s Fayetteville Regional Office.

Other petroleum retail stations are currently operating on the southern adjoining property across the
intersection of W R Latham Street and Green Street (Scotchman) and on the southwestern adjoining
property across Green Street (TS Mart). Incidents documented at these two operating gas station facilities
have reportedly achieved regulatory closure with NCDEQ’s Fayetteville Regional Office.

C.3 Previous Investigations
The previous investigations conducted at this site are summarized below. For a more in-depth summary
of previous investigations, please see Terracon’s Monitoring Report, dated April 4, 2016, on file at NCDEQ’s
State Lead Program Office in Raleigh, NC.

Eleven USTs have historically been associated with the site. Six of these USTs were installed in January

1964 and removed in September 1994. The seventh UST was installed in January 1995 and removed in
January 2007. A release incident was associated with the USTs removed in 1994 (Incident No.: 13245)
and then was later combined with the site’s current incident (Incident No.: 17850) that is associated with
the UST removed in 2007.

On June 15, 2015, three additional USTs were removed from the site and one UST was abandoned-in-
place due to its proximity to a canopy footing. At least one target contaminant was analyzed to be above
NCDEQ’s Soil-to-Water Maximum Contaminant Concentrations (MSCCs) in confirmation soil samples
collected after the 2015 tank removal activities. None of these soil exceedances were above NCDEQ’s
Residential or Industrial/Commercial MSCCs. Soil removal was limited due to the location of the shop
building and canopy footings.

To date, a network of 12 monitoring wells (MW-1 through MW-12) have been installed for the ongoing
release investigation. Two of these wells (MW-10 and MW-11) have been installed off-site on the eastern
undeveloped grassed field to the east across 710 Bypass. An additional well, MW-18, was installed on-site
as part of an off-site investigation from a former gas station (Clarkton BP – Incident 29290) that formerly
occupied one of the eastern adjoining properties. Monitoring well MW-2 was replaced by MW-2R in 2010
after well MW-2 was found to be destroyed. Monitoring well MW-2R has not been located since 2012 and
is assumed to have been destroyed or covered by concrete driveway patching. During the January 2018
sampling event, Terracon could not locate MW-18. Later it was determined that MW-18 has been
abandoned and the incident associated with this monitoring well has been closed by NCDEQ’s Fayetteville
Regional Office.

Several rounds of groundwater monitoring and MMPE events have been performed at the site since the
tank removal activities of 2015. Free product has historically and is currently located in MW-1.

Benzene above the GCL has historically been identified in MW-9 and MW-12. Benzene has historically
been identified in MW-2R at concentrations above the GCL; however, this well was last sampled in 2012.

Between June 24, 2019 and June 28, 2019, Advanced Environmental performed a 96-hour MMPE event
on monitoring wells MW-1, MW-6, MW-8, MW-9 and MW-12. The total liquid volume recovered during the
MMPE event was reported to be 4,706 gallons with an additional estimated 4.75 gallons of vapor phase
product (gasoline) recovered. Approximately 18-gallons of free product were recovered as liquid in the
tanker.

Terracon returned to the site on July 30, 2019 in order to gauge the free product thickness in MW-1 using
an oil/water interface probe. Free product thickness was documented to be 0.06 feet in MW-1 on this date.

Groundwater flow has historically been documented to occur generally to the southwest, south, southeast.
Localized radial flow has consistently been inferred near wells MW-8 and MW-12.

Additional environmental investigations have not occurred on-site after the June 2019 MMPE event until the
current groundwater monitoring well sampling event occurred in November 2019.

C.4 Water Supply Wells
A receptor survey was not performed during the March 2019 event. A receptor survey update was most
recently performed as part of the January 2018 services.

During the January 2018 receptor survey update, potential water supply well pump houses were identified
at residences along Hester Street (161 West Hester Street (PWSW-1) and 45 West Hester Street (PWSW-
3)) and along Melvin Street (79 Melvin Street (PWSW-2)). Water meters were observed in the front yard
of each of these residences. Potential well PWSW-1 at 161 West Hester Street is located approximately
530 feet east of the site; potential well PWSW-2 at 79 Melvin Street is located approximately 950 feet
southwest of the site and potential well PWSW-3 at 45 West Hester Street is located approximately 1,100
feet southeast of the site. According to the Town of Clarkton, these residences are connected to the town
water supply.

As part of the January 2018 scope of work, Terracon mailed receptor survey letters to the current or past
property owners, if property owner information was readily available, to properties identified as containing
PWSW-1, PWSW-2 and PWSW-3.

Terracon received a response via email from a former property owner where PWSW-1 was identified. The
prior property owner indicated that he inherited the property from his parents and that he recently sold the
property. The property owner confirmed that PWSW-1 was at one time used as a water supply well used
for watering a garden at this residence and was used for irrigation purposes and that this well had not been
active for at least 5 years prior to the time he sold the property. The former property owner also indicated
that the property is connected to municipal water. Terracon attempted to contact the current property
owner, Ms. Sandra Jones; however, at the issuance of this report, letters sent to Ms. Jones have been
returned as undeliverable. Terracon obtained Ms. Jones’ mailing address from the Bladen County Tax
Office and GIS website. Alternative mailing addresses have not been identified for Ms. Jones. No one was
at home at the time of our January 16, 2018 site visit.

Terracon received a response by mail from the property owner where PWSW-2 was identified. According
to the response, this property does not contain a water supply well and is connected to municipal water.
During Terracon’s site visit on January 16, 2018, the door to the formerly identified well house at this
property was open and it appeared as if the structure was used as a storage building.

At the issuance of this report, Terracon has not received a response from the property owner where PWSW-
3 was observed to be located. During our site visit in January 2018, Terracon drove by this property and
no one was at home. Terracon was able to observe the potential well house at this property from the
backside of the house. The potential well house was observed to be a small structure connected to the
back side (south side) of the residence.

In January 2018, Terracon sent receptor survey letters to property owners within 1,000 feet of the source
area inquiring about whether water supply wells were utilized on their properties. Terracon additionally
performed a drive around of the 1,000-foot radius to attempt to identify additional supply wells. Of the
receptor survey forms returned to Terracon, none indicated that they utilized a water supply well for drinking,

irrigation, filling pools, washing cars or other uses. Terracon did not identify additional water supply wells
during our windshield reconnaissance.

A municipal water supply well (Well # 1) is located approximately 1,150 feet northeast of the source area and
a second water supply well (Well # 3) is located approximately 1,350 feet southeast of the source area. Well
#1 and Well #3 are considered to be within wellhead protection areas. Municipal water is reportedly utilized at
the site and within the Town of Clarkton.

Results of the 2018 water supply well inventory are depicted on Exhibit 9.

C.5 Surface Water
A ditch containing water on the date of our site visit was observed on the eastern adjoining property across
W R Latham Street. According to the Clarkton, NC Quadrangle USGS topographic map, an unnamed “blue
line” stream is located approximately 1,000 feet north of the site. The “blue line” stream to the north appears
to be an unnamed tributary of Brown Marsh Swamp located farther north and east of the site. Surface
waters are depicted on Exhibit 1.

C.6 Land Use Information
The adjacent property to the north consists of a warehouse and a building that sells ice. Adjoining property
to the east is W R Latham Road with a restaurant (a former gas station) and a grassed lot across the road.
Adjoining the property to the south is the intersection of W R Latham Road and West Green Street (Hwy
211) with a Scotchman gas station that contains a Subway restaurant across the intersection. Adjoining
property to the southwest is West Green Street with TS Mart gas station/Harvey’s Diner and a Dollar
General across the road.
D. ASSESSMENT INFORMATION
D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.

The site is located in the Coastal Plain Region (Inner Coastal Plain). The Inner Coastal Plain is generally
a higher, denser area of rich, sandy soil. Also found in the Inner Coastal Plain are the Sandhills; a subregion

of rolling, sandy hills. The Coastal Plain Region was developed on loose, unconsolidated and flat layers of
sediment, caused by sea level changes and erosion of the mountains. Most parts of the Coastal Plain
Region consist of well to moderately well-drained loamy soils.

The site is underlain by a sequence of marine sediments of the Tertiary age known as the Yorktown/Duplin
Formation, Undivided (Tpy). The Yorktown Formation consists of fossiliferous clay with fine grained sand;
shell material mainly found in the lenses. The Duplin Formation is shelly, medium to fine grained sand,
sandy marl and limestone.

Information obtained from the Web Soil Survey for Bladen County, depicts soils on the site as Norfolk-
Urban land complex, 0 to 6 percent slopes (NuB). Urban land soils are soils that have been altered by
development, undercutting and paving over the years. The Norfolk portion of this complex are well drained
soils with very low runoff.

In the site area, groundwater generally is obtained from the Black Creek Aquifer. The Black Creek Aquifer
is lagoonal to marine consisting of thinly laminated clay interlayered with sand. Sediments in the subsurface
are highly organic and sediments are typically from the Black Creek and Middendorf formations. On
average, the Black Creek aquifer consists of nearly 60 percent sand. The hydraulic conductivity ranges
from 15 to 50 feet/day and averages 28 feet/day. Recharge occurs mainly by the downward percolation
from the overlying aquifers. Discharge is typically into streams where there are channels cut into it or its
overlying confining unit.

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, 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. The general groundwater flow direction is interpreted to be toward the south and
southeast from the site based upon depth to water level measurements obtained during the November
2019 sampling event with depth to groundwater ranging from 3.35 (in MW-12) to 10.85 (in MW-3) feet below
the top of casing (TOC). A Groundwater Elevation Map with potentiometric contours is included as Exhibit
4 in the Appendix.

D.2 Sampling Activities
Terracon mobilized to the site on November 14, 2019 to assess free product in monitoring well MW-1 and
to conduct groundwater sampling as requested by NCDEQ. Gauging and sampling activities are discussed
in Sections D.2.1, D.2.2 and D.2.3 of this report.

free product in MW-1. In order to verify the interface meter, Terracon utilized a disposable bailer to verify
the absence of free product in the well. Approximately 0.04 feet (or 0.5 inches) of free product was observed
inside the bailer (see Photo 2, Appendix B). Due to the presence of free product, MW-1 was not sampled.
The free product thickness in MW-1 has decreased significantly since an MMPE event was conducted in
June 2019.

Free product was not encountered in the other wells gauged during this assessment.

D.2.2 Groundwater Sampling Activities
Groundwater samples were collected from MW-3, MW-4, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11 and
MW-12 during this sampling event.

Prior to purging, Terracon gauged the depths-to-water in monitoring wells MW-3, MW-4, MW-6, MW-7,
MW-8, MW-9, MW-10, MW-11 and MW-12. The approximate locations of the wells are shown on the
Former UST Location Diagram (Exhibit 2) and subsequent maps appended to this report (Exhibits 3
through 8). Current and historical groundwater elevation measurements are provided in Table 2.

After each well was gauged, the wells were then purged using a dedicated disposable bailer until at least 3
well volumes of water were purged from each well or until the well purged dry.

As a quality control measure, Terracon prepared a field blank using distilled water. The field blank sample
was indicated as sample “MW-W” on the chain-of-custody.

The samples were placed in laboratory-supplied glassware, labeled and stored in an ice-packed cooler.
The samples, along with chain-of-custody documentation, were delivered to Pace Analytical Services, Inc.,
in Huntersville, North Carolina for analysis of VOCs, including xylenes, MTBE, EDB and IPE, by EPA
Method 6200B.

D.2.3 Analytical Results

As discussed above, free product was observed in well MW-1.

Benzene has historically been detected at concentrations exceeding its GCL in onsite monitoring wells MW-9
and MW-12. However, during the recent groundwater sampling event in November 2019, the benzene levels
in MW-9 and MW-12 were reported as 3,110 µg/l and 4,120 µg/l, below the NCDEQ established GCL of 5,000
µg/l for benzene. The benzene level in monitoring well MW-9 has increased significantly since its sampling
event in March 2019 (was 619 µg/l at that time). The benzene level in monitoring well MW-12 also decreased
from the prior event and has decreased significantly since MW-12 was initially sampled in January 2016. The
MMPE was performed on both MW-9 and MW-12 during the June 2019 event.

The groundwater samples collected from monitoring wells MW-3, MW-4, MW-6, MW-8, MW-9 and MW-12
contained at least one target petroleum constituent that exceed the applicable 2L Standard. Concentrations of
target contaminants in wells MW-3 and MW-12, generally appear to be decreasing. Concentrations of target

contaminants in wells MW-4, MW-6, MW-8 and MW-9, general appear to be increasing or staying near the
same levels.

The groundwater samples collected from monitoring wells MW-7, MW-10 and MW-11 were analyzed to contain
at least one target petroleum constituent above the laboratory’s reportable limits, but below the 2L Standard.
Concentrations in these three wells have trended downward since 2011.

Although target contaminants of concern were detected above the laboratory’s method detection limits in
groundwater samples collected from down-gradient onsite well MW-7 and offsite down-gradient wells, MW-
10 and MW-11, these constituents were reported at concentrations below their respective 2L Standards.
Samples from well MW-7 and MW-10 have historically contained MTBE at concentrations slightly above
the 2L Standard of 20 µg/l. During this recent sampling event and the sampling events in July 2014, January
2015, January 2016, January 2018 and March 2019, MTBE concentrations in well MW-10 were analyzed
to be below the 2L Standard. The January 2016 sampling event was the first time that MTBE concentrations
in MW-7 were documented to be below the 2L Standard.

A Groundwater Analytical Results Map is provided as Exhibit 5 that indicates contaminants detected and
their levels for each well. Concentration maps for benzene, MTBE and naphthalene are provided in
Exhibits 6 through 8, respectively. As indicated on the above exhibits, the estimated lateral extent of
dissolved phase impact above the 2L Standards appears reasonably defined by the existing monitoring
well network.

The groundwater analytical results from the monitoring wells are summarized in Table 1. A copy of the
laboratory analytical reports is provided in Appendix A.
E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of the monitoring activities performed in November
2019, Terracon provides the following findings and conclusions:

Free product was observed in monitoring well MW-1 at an apparent thickness approximately 0.04 feet
(or approximately 0.5 inches). The free product thickness level in MW-1 has decreased significantly
since the March 2019 gauging event and after a MMPE event that was performed at the site in June
2019.
Benzene has historically been detected at a concentration exceeding its GCL in onsite monitoring well
(MW-12). However, during the recent groundwater sampling event in November 2019, the benzene
level at MW-12 was at 4,120 µg/l and below the NCDEQ established GCL of 5,000 µg/l for benzene.
Historically, benzene exceeding GCLs have also been detected in monitoring well MW-9. The benzene
level in MW-9 was detected at 3,110 µg/l in November 2019 and below the NCDEQ established GCL for
benzene. The benzene level in monitoring well MW-9 has increased significantly since its sampling event
in March 2019 (was 619 µg/l at that time). The benzene level in monitoring well MW-12 decreased since
its initial sampling event in January 2016. The MMPE was performed on both MW-9 and MW-12 in June
2019.

The groundwater samples collected from monitoring wells MW-3, MW-4, MW-6, MW-8, MW-9 and MW-
12 contained at least one target petroleum constituent that exceed the applicable 2L Standard.
Concentrations of target contaminants in these wells generally appear to be stable or decreasing.
The groundwater samples collected from monitoring wells MW-7, MW-10 and MW-11 were analyzed to
contain at least one target petroleum constituent above the laboratory’s reportable limits, but below the
2L Standards. Concentrations in these three wells have been less than the 2L Standards for four or
more monitoring events.
The lateral extent of groundwater impact generally appears to be defined by the existing monitoring well
network.
The general groundwater flow direction appears to be towards the south and southeast.
A receptor survey was not performed during the March 2019 event. A receptor survey update was most
recently performed as part of the January 2018 services.
The 2018 receptor survey confirmed the presence of a potential inactive non-potable water supply well
previously identified as PWSW-1 located approximately 530’ east of the source area (the former UST
basin).
The property owner where a prior potential water supply well (PWSW-2) was identified to be located
indicated that no water supply well is present at this property and that this property is connected to
municipal water.
Terracon also attempted to contact the property owner where potential supply well PWSW-3 was
previously identified. At the issuance of this report, a response has not been received from this property
owner.
A municipal water supply well (Well # 1) is located approximately 1,150 feet northeast of the source area
and a second water supply well (Well # 3) is located approximately 1,350 feet southeast of the source
area. Well #1 and Well #3 are considered to be within wellhead protection areas. Municipal water is
reportedly utilized at the site and within the Town of Clarkton.

Based on the data presented in this Monitoring report, Terracon recommends the following activities be
completed at the site:

Install a replacement well cover for MW-10 that was found to have been missing during the November
2019 site visit.
The continued monitoring of the groundwater quality onsite by conducting semi-annual groundwater
sampling events.
Perform high resolution evaluation using laser-induced fluorescence (LIF) technology to obtain additional
information on the free product distribution at the site.

1/16/18 MW-18 could not located on this date,
reportedly abandoned in May 2016.

Table 2 indicates the eight latest groundwater elevation datum obtained at the site, including the most current groundwater elevation data
obtained on 11/14/19, if applicable.

MW-5 has not been located during Terracon’s site visits and has been reported as being destroyed in past reports. MW-2R has also not be
located during Terracon’s site visits. MW-18, installed for an off-site release, was located near where MW-2R was reported to be located and
has previously been used in the place of MW-2R during Terracon’s groundwater sampling events. Terracon could not locate MW-18 during
our site visit on 1/16/18. A June 14, 2016 document found on NCDEQ’s online report repository indicated that MW-18 was abandoned on
May 16, 2016.

*Please note that Terracon established a new bench mark during our groundwater elevation evaluation on 7/23/14 due to the past consultant
bench mark being unknown at the time of our site visit. This bench mark is a water meter cover near the southwestern property corner and
Terracon used an assumed elevation of 100.00 feet.

N/M = Not Measured; N/O = Not Observed (Free Product Not Observed); A = Ft.-TOC. – Water level measured from the top of the well
casing; B = Ft.-Elev. – Elevation in feet.
