EXECUTIVE SUMMARY
Hill’s Grocery is located at Highway 242 North (Main Street) in Salemburg, Sampson County, North
Carolina. The site is located at the intersection of Main Street and Pine Street. The last day of operation
was June 25, 1990. On July 17, 1996, two 4,000-gallon gasoline USTs, one 550-gallon kerosene UST, and
associated piping were removed from the site.

According to the information obtained in 2015, two municipal water supply wells for the Town of
Salemburg are located approximately 550 feet northwest (TWS-1) and 1,115 feet north-northeast (TWS-
2) of the site. Both town wells are in use and draw water from approximately 36 feet below ground
surface and provide municipal water to the site and surrounding properties. However, the site is not
located within a designated wellhead protection area. In addition, three private non-potable water supply
wells (WSW-2, WSW-3, and WSW-4) were identified within 1,500 feet of the site. No water supply wells
were identified within a 250-foot radius of the site. No surface water bodies were identified within 500
feet of the site. The site is classified as high risk.

On January 25, 2023, thirteen monitoring wells (MW-2R, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9 and
MW-11 through MW-16) and one telescoping well (TW-1) were gauged, purged, and sampled.
Concentrations of benzene, toluene, ethylbenzene, xylenes, naphthalene, tert-Amyl alcohol,
isopropylbenzene, n-propylbenzene, 1,2,4 trimethylbenzene, and/or 1,3,5 trimethylbenzene in the
ground water samples from MW-2R, MW-3, MW-5, MW-8, MW-9, MW-11, and MW-13 exceeded the
MACs. No reported contaminant concentrations exceeded the GCLs.

Hill’s Grocery has not functioned as a petroleum retail facility since 1990. The Salemburg Food Mart,
located north of Hill’s Grocery, has had active USTs until 2019 and has had a reported release (29719). In
2016, a ground water model showed contaminant ground water impact north of Pine Street at the
Salemburg Food Mart site and at the commercial automotive shop located on the northeast corner of
Main Street and Pine Street. Ground water contamination reported in wells MW-8 and MW-9 should be
the responsibility of Salemburg Food Mart; therefore, assessment and remediation north of Pine Street
should be conducted by Salemburg Food Mart. In addition, future ground water sampling events should
not include sampling MW-8 and MW-9 or laboratory analysis of oxygenates for samples associated with
Hill’s Grocery.

Hill’s Grocery has not functioned as a petroleum retail facility since 1990 and ground water contamination
continues to exceed the MACs. In addition, results of the fate and transport simulation conducted in 2015
indicate the contaminant plume will extend to the distance of the down-gradient municipal supply well.
Based on this information, the site should remain at high risk and a Corrective Action Feasibility Study
should be conducted to identify a remedial plan. A ground water sampling event should be conducted in
June 2023.

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of the January 2023 ground water sampling event at the Hill’s Grocery site;
located at Highway 242 North in Salemburg, Sampson County, North Carolina (Figures 1 and 2). These
activities were conducted in accordance with GRI Proposal No. 22-907. State correspondence has been
included as Appendix A.

The site is currently vacant and owned by Ronnie Sherrill Strickland. On July 17, 1996, two 4,000-gallon
gasoline, one 550-gallon USTs, and associated piping were removed from the site. The last date of
operation was June 25, 1990. The USTs were emptied prior to closure activities in 1996. Approximately
24 tons of contaminated soil were removed from the site during tank removal. According to available
correspondence, a CSA and CAP were completed in 1991. A subsequent CSA was completed by Geological
Resources, Inc. in March 2012. To date, sixteen Type II monitoring wells and one Type III monitoring well
have been installed for this incident. A Site Map showing the locations of the monitoring wells and the
structures of on-site and surrounding properties has been included as Figure 3. UST owner/operator
information and UST system information are included as Tables 1 and 2, respectively. The Registered
Tank Report is shown below:

According to the information obtained during ground water monitoring activities in 2010, two municipal
water supply wells for the Town of Salemburg are located approximately 550 feet northwest (TWS-1) and
1,115 feet north-northeast (TWS-2) of the site. Both town wells are in use and draw water from
approximately 36 feet below ground surface and provide municipal water to the site and surrounding
properties. It is possible that these wells are drawing ground water from the Black Creek Aquifer, which
is the major source of potable ground water in this region of the Coastal Plain. However, the site is not
located within a designated wellhead protection area. In addition, three private water supply wells (WSW-
2, WSW-3, and WSW-4) were identified within 1,500 feet of the site. According to the information
provided, these private water supply wells are used for non-potable purposes. No water supply wells

were identified within a 250-foot radius of the site. Water supply well owner information and adjacent
property owner information is included in Tables 3 and 4, respectively.

No surface water bodies were identified within 500 feet of the site. Land use in the area is single family
residences and commercial. Therefore, the incident risk is classified as high risk and ground water
contamination must be remediated to concentrations less than the MACs.

A fate and transport simulation requested by the NCDEQ to evaluate whether any receptors would be at
risk if the plume were to migrate from the source area was completed in 2015. The fate and transport
simulation indicated that the xylenes plume will migrate the distances of TWS-1 and TWS-2 at
concentrations exceeding the MAC in approximately 68 and 186 years, respectively. Please note, TWS-1
is not located in the historic down-gradient direction. Due to the uncertainty as to whether or not the
Black Creek Aquifer could be at risk from the contaminant plume migration, and the modeling results
indicating that the municipal well(s) will be impacted, GRI recommended that the site risk classification
should remain High Risk and a Corrective Action Feasibility Study should be developed and implemented
for the site.

Please refer to previous submittals for further historical information regarding the site.
2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL
ASSESSMENT INFORMATION
On January 25, 2023, thirteen monitoring wells (MW-2R, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9 and
MW-11 through MW-16) and one telescoping well (TW-1) were gauged. MW-10 was not located during
the sampling event. Depths to ground water in the Type II monitoring wells ranged from 13.24 feet to
14.55 feet. Ground water elevations in the Type II monitoring wells ranged from 85.62 feet to 86.64 feet.
Ground water flow was generally to the east with a horizontal gradient of less than 0.01 feet per foot
between MW-14 and MW-15. The vertical gradient between paired wells MW-3 and TW-1 was less than
0.02 feet per foot in the downward direction. 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

On January 25, 2023, thirteen monitoring wells (MW-2R, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9 and
MW-11 through MW-16) and one telescoping well (TW-1) were gauged, purged and sampled. MW-10
was not sampled. MW-16 was not sampled due to insufficient water. Ground water samples collected
from the monitoring wells were submitted for laboratory analyses using EPA Method 6200B with
oxygenates.

Concentrations of benzene, toluene, ethylbenzene, xylenes, naphthalene, tert-Amyl alcohol,
isopropylbenzene, n-propylbenzene, 1,2,4 trimethylbenzene, and/or 1,3,5 trimethylbenzene in the
ground water samples from MW-2R, MW-3, MW-5, MW-8, MW-9, MW-11, and MW-13 exceeded the
MACs as specified in T15A NCAC 2L.0202. No reported contaminant concentrations exceeded the GCLs.
A summary of the analytical results for ground water samples collected on January 25, 2023 is presented
in Table 6. Field parameters are summarized in Table 7. A Ground Water Quality Map based on the
January 2023 data is included as Figure 5. Isoconcentration maps for benzene, xylenes and naphthalene
are included as Figures 6, 7 and 8, respectively. A complete report of laboratory analyses of the ground
water samples collected from the monitoring wells during the January 2023 sampling event has been

water column height. A theoretical contaminant mass area was calculated around MW-2R, MW-3, MW-
5, MW-11, and MW-13 and used in the contaminant mass calculations. The total contaminant mass of
the site has decreased 77% since August 2011. Contaminant mass calculations have been included as
Appendix C. A map of the contaminant mass areas has been included as Figure 9. A chart depicting the
overall trend in contaminant mass is shown below:

Street at the Salemburg Food Mart site and at the commercial automotive shop located on the northeast
corner of Main Street and Pine. Therefore, assessment and remediation north of Pine Street should be
conducted by Salemburg Food Mart. Salemburg Food Mart is no longer operating; environmental
assessment has transferred to the NC State Lead Program.
3.0 FREE PRODUCT REMOVAL
No free product has been observed at the site.
4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS
A CAP was completed for the site in 1991; however, no natural attenuation monitoring plan is currently
in place at the site.
5.0 CONCLUSIONS
 On January 25, 2023, thirteen Type II monitoring wells and one telescoping well were gauged,
purged, and/or sampled. Ground water flow was generally to the east with a horizontal gradient
of less than 0.01 feet per foot. The vertical gradient between paired wells MW-3 and TW-1 less
than 0.02 feet per foot in the downward direction.
 Concentrations of benzene, toluene, ethylbenzene, xylenes, naphthalene, tert-Amyl alcohol,
isopropylbenzene, n-propylbenzene, 1,2,4 trimethylbenzene, and/or 1,3,5 trimethylbenzene in
the ground water samples from MW-2R, MW-3, MW-5, MW-8, MW-9, MW-11, and MW-13
exceeded the MACs. No reported contaminant concentrations exceeded the GCLs.
 The baseline contaminant mass at the site was determined based on the total BTEX and MTBE
concentrations from the August 2011 ground water sampling event, as well as the maximum
historical water column height. A theoretical contaminant mass area was calculated around MW-
2R, MW-3, MW-5, MW-11, and MW-13 and used in the contaminant mass calculations. The total
contaminant mass of the site has decreased 77% since August 2011.
 Hill’s Grocery has not functioned as a petroleum retail facility since 1990. The Salemburg Food
Mart, located north of Hill’s Grocery, has had active USTs until 2019 and has had a reported
release (29719). In 2016, a ground water model showed contaminant ground water impact north
of Pine Street at the Salemburg Food Mart site and at the commercial automotive shop located
on the northeast corner of Main Street and Pine Street. Ground water contamination reported in
wells MW-8 and MW-9 should be the responsibility of Salemburg Food Mart; therefore,
assessment and remediation north of Pine Street should be conducted by Salemburg Food Mart.
In addition, future ground water sampling events should not include sampling MW-8 and MW-9
or laboratory analysis of oxygenates for samples associate with Hill’s Grocery.
 Based on this information, the risk classification for the site should remain high risk and
remediation should be conducted. A Corrective Action Feasibility Study should be completed. A
ground water sampling event should be conducted in June 2023.

Project: Hils Grocery Lab Report Number: 23-030-0003
Date: 2/7/2023
Volatile Organic Compounds - GC/MS Method 6200B Analyte: 2-Butanone QC Batch No: V29470/V29469
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: 3,3-Dimethyl-1-butanol QC Batch No: V29470/V29469
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: 3,3-Dimethyl-1-butanol QC Batch No: V29559/V29469
3,3-Dimethyl-1-butanol fails low for the LCS but passes for all other QC. No hits in the sample. No further action taken.
Analyte: Acetone
QC Batch No: V29470/V29469 Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: Carbon Tetrachloride
QC Batch No: V29529/V29469 Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be acceptable.
Analyte: tert-Amyl alcohol
QC Batch No: V29470/V29469 Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: tert-Amyl alcohol QC Batch No: V29559/V29469 Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: tert-Butyl alcohol

Notes:
• FP: Free Product
• Area of the contaminant plume is calculated from Figure 8.
• 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.
