EXECUTIVE SUMMARY
John’s Citgo Service, Inc. is located at 211 North Main Street in Red Springs, Robeson County, North
Carolina. The site is currently occupied by a used automobile dealership. The adjoining properties are
commercial and residential. On January 7 and 8, 2019, one 1,000-gallon diesel, one 4,000-gallon gasoline,
two 10,000-gallon gasoline, and two 8,000-gallon gasoline USTs, associated dispensers, and product
piping were removed from the site. Four 4,000-gallon gasoline USTs were removed from the site on
December 21, 1988. One 1,000-gallon kerosene and one 550-gallon oil USTs were removed from the site
on August 6, 1996. A release was reported in August 1989 and UST Incident #5189 was assigned.
Based on the March 2019 receptor survey, three non-potable water supply wells were identified within a
1,500-foot radius of the site. No water supply wells were identified within a 250-foot radius of the source
area. Public water is available to the site and the surrounding properties. A small, spring-fed wetland has
been identified approximately 430 feet north of the source area.
On April 4, 2023, eight Type II monitoring wells (MW-2, MW-3, MW-5, GMW-1, GMW-3, GMW-4, GMW-
7 and GMW-8) were gauged, purged and sampled in accordance with NCDEQ guidelines. Concentrations
of individual BTEX constituents, MTBE, naphthalene, n-butylbenzene, p-isopropyltoluene, n-
propylbenzene, vinyl chloride, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded the
MACs were reported in the ground water samples collected from GMW-1, GMW-3, GMW-4, GMW-7,
GMW-8, MW-2 and MW-3. Concentrations of benzene and/or toluene that exceeded ten times the NCAC
2B Surface Water Standards were reported in the ground water samples collected from GMW-7, MW-2
and MW-3. All of the reported contaminant concentrations were less than the GCLs. Free product was
not observed.
The contaminant mass at the site has reduced 81% since May 2020.
Based on this information, a contaminant Fate & Transport Model should be completed and a change of
site risk classification can be considered pending the results.

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of the April 2023 ground water sampling event at the John’s Citgo Service, Inc.
site; located at 211 North Main Street in Red Springs, Robeson County, North Carolina (Figure 1). These
activities were conducted in accordance with GRI Proposal No. 22-837, which was submitted to NCDEQ
on February 15, 2023, and was approved as Task Authorization No. 5189-013 on February 16, 2023. State
correspondence has been included as Appendix A.
The site is currently owned by John’s Texaco Service, Inc. The former petroleum retail facility and
convenience store was also operated by John’s Texaco Service, Inc. The site is currently occupied by a
used automotive dealership. On January 7 and 8, 2019, one 1,000-gallon diesel, one 4,000-gallon gasoline,
two 10,000-gallon gasoline, and two 8,000-gallon gasoline USTs, associated dispensers and product piping
were removed from the site. Four 4,000-gallon gasoline USTs were removed from the site on December
21, 1988. One 1,000-gallon kerosene and one 550-gallon oil USTs were removed from the site on August
6, 1996. A release was reported in August 1989 and UST Incident #5189 was assigned. UST
owner/operator information and UST system information are included as Tables 1 and 2, respectively.
The Registered Tank Report is shown below:
During past assessment activities, fourteen Type II monitoring wells (MW-1 through MW-6 and GMW-1
through GMW-8) and one Type III monitoring well (TW-1) were installed at the site. MW-1 has since been

destroyed, and MW-6 has historically been a dry well. A Site Map showing the locations of the monitoring
wells and the structures on-site has been included as Figure 2.
A receptor survey was conducted on March 22, 2019. Three non-potable water supply wells were
identified within a 1,500-foot radius of the site. No water supply wells were identified within a 250-foot
radius of the source area. Public water is available to the site and the surrounding properties. Water
supply well information is presented in Table 3. Adjacent property owner information is presented in
Table 4.
A small, spring-fed wetland was identified approximately 430 feet north of the site. Based on the presence
of surface water bodies within 500 feet of the source area, the existence of free product and ground water
contaminant concentrations above ten times the NCAC 2B surface water standards, the site’s risk had
been classified as intermediate. A Site Vicinity Map showing the adjacent properties, water supply well
locations and the location of the surface water body has been included as Figure 3.
A CAP has not been developed for this incident.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On April 4, 2023, eight Type II monitoring wells (MW-2, MW-3, MW-5, GMW-1, GMW-3, GMW-4, GMW-
7 and GMW-8) were gauged, purged and sampled in accordance with NCDEQ guidelines. Depths to
ground water in the Type II monitoring wells ranged from 11.07 feet to 13.35 feet below the tops of well
casings. Ground water elevations in the Type II monitoring wells ranged from 84.75 feet to 87.79 feet.
Ground water flow was generally to the northeast with a horizontal hydraulic gradient of approximately
0.02 feet per foot. Well construction and gauging information is presented in Table 5. A Water Table
Surface Map based on the Type II monitoring wells is included as Figure 4. A summary of the current
ground water gauging data is shown below:

Ground water samples collected from the monitoring wells were submitted for laboratory analyses of
VOCs using EPA Method 6200B and natural attenuation parameters (nitrate, sulfate, ferrous iron and
methane). Additionally, field parameters (dissolved oxygen, oxidation reduction potential, temperature,
pH and conductivity) were measured for all sampled wells.

Concentrations of individual BTEX constituents, MTBE, naphthalene, n-butylbenzene, p-isopropyltoluene,
n-propylbenzene, vinyl chloride, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene that exceeded
the MACs were reported in the ground water samples collected from GMW-1, GMW-3, GMW-4, GMW-7,
GMW-8, MW-2 and MW-3. Concentrations of benzene and/or toluene that exceeded ten times the NCAC
2B Surface Water Standards were reported in the ground water samples collected from GMW-7, MW-2
and MW-3. All of the reported contaminant concentrations were less than the GCLs. Free product was
not observed. A summary of the analytical results for ground water samples collected on April 4, 2023, is
presented in Table 6. A summary of natural attenuation parameter results is presented in Table 6A. A
Ground Water Quality Map based on the April 2023 data is included as Figure 5. A complete report of
laboratory analyses of the ground water samples collected from the monitoring wells during the April
2023 sampling event has been included as Appendix B. A summary of the current ground water analytical
data is shown below:

The baseline contaminant mass at the site was determined based on the total BTEX, MTBE, and
naphthalene concentrations from the May 2020 ground water sampling event as well as the maximum
historical water column height observed in each area. The contaminant plume consists of one area based
on the toluene concentrations during the May 2020 ground water sampling event. The contaminant mass
at the site had decreased by 81% between May 2020 and April 2023. Please note, MW-4, GMW-5 and
GMW-6 were not sampled during the April 2023 sampling event and the last known concentrations were
used for calculations. Contaminant mass calculations have been included as Appendix C. A map of the
contaminant mass area has been included as Figure 6. A chart depicting the overall contaminant mass
trend is shown below:

The site is located in the Coastal Plain Physiographic Province of North Carolina. The water table has a
seasonal high depth to water of approximately nine to fifteen feet bgs.
Please note that since a CAP has not been completed for the site, contaminant milestones have not been
established.
3.0 FREE PRODUCT REMOVAL
During the April 2023 sampling event, no free product was observed. Free product has historically been
present in GMW-5 and MW-3. An AFVR event was conducted on MW-3 in October 2019 and GMW-5 in
January 2022. Free product has not been detected in MW-3 since 2020 and in GMW-5 since January 2022.
4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
Since a CAP has not been developed for this incident, no natural attenuation monitoring plan is currently
in place at the site. No contaminant reduction milestones have been established for this incident.
5.0 PROPOSED REMEDIAL ACTION
Prior to the discovery of free product in GMW-5, the proposed remedial action for the incident was to
complete a Contaminant Fate & Transport Model in order to determine if contaminant constituents would
reach the spring-fed wetland area within 500 feet of the site. The Contaminant Fate & Transport Model

could not be completed due to the presence of free product. Additionally, due to the drop in the ground
water level at the site since 2021, insufficient water volume has been present in wells at the site to allow
for proper analyses collection. Ground water was sufficient during the April 2023 sampling event and
natural attenuation parameters were able to be collected. A contaminant Fate & Transport Model can
now be completed, and the risk classification can be re-evaluated.
6.0 CONCLUSIONS
On April 4, 2023, eight Type II monitoring wells MW-2, MW-3, MW-5, GMW-1, GMW-3, GMW-4,
GMW-7 and GMW-8) were gauged, purged and sampled in accordance with NCDEQ guidelines.
Ground water flow was generally to the northeast with a horizontal hydraulic gradient of
approximately 0.02 feet per foot.
Concentrations of individual BTEX constituents, MTBE, naphthalene, n-butylbenzene, p-
isopropyltoluene, n-propylbenzene, vinyl chloride, 1,2,4-trimethylbenzene and/or 1,3,5-
trimethylbenzene that exceeded the MACs were reported in the ground water samples collected
from GMW-1, GMW-3, GMW-4, GMW-7, GMW-8, MW-2 and MW-3. Concentrations of benzene
and/or toluene that exceeded ten times the NCAC 2B Surface Water Standards were reported in
the ground water samples collected from GMW-7, MW-2, and MW-3. All of the reported
contaminant concentrations were less than the GCLs. Free product was not observed.
The contaminant mass at the site has decreased by 81% since May 2020.
Based on this information, a contaminant Fate & Transport Model should be completed and a
change of site risk classification can be considered pending the results.

Dear Mr. Robertson:
The Monitoring Report dated October 27, 2022, has been reviewed and you are requested to proceed
with your consultant’s recommendations as stated in the report conclusions. The next sampling event should
be scheduled to occur during April 2023 using a reduced number of monitoring wells. Perhaps by that time the
static water levels will have increased sufficiently enough to schedule a Fate & Transport Model.
If you have questions regarding the information contained in this letter, please contact me at the
Fayetteville Regional Office address below or at (910) 433-3347.
Sincerely,
Kenneth E. Currie, Hydrogeologist

Notes:
• FP: Free Product
• Area of the contaminant plume is calculated from Figure 6
• Height of the water column is calculated by subtracting the average depth to water from the average well depth of the referenced monitoring wells
• Volume of the contaminant plume is calculated by multiplying the area of the plume by the average height of the water column during each sampling event
• Effective porosity is assumed based on the sub-surface soil profile obtained from well construction records and soil boring logs
• Total mass was calculated by multiplying the total contaminant concentrations for the sampling event with effective volume
• Contaminant mass cannot be calculated in wells containing FP; therefore, the total contaminant mass is based on the known concentrations in the area for each sampling event.
• When areas couldn’t be sampled, the last known concentrations were used in the calculations.
