2.0 Executive Summary
For the groundwater sampling event conducted on November 21 and November 22, 2022, the following summary is presented.
2.1 Free Product
Free product has not been detected historically at this site.
2.2 Groundwater Contaminant Concentrations
The maximum concentrations of dissolved groundwater contaminants detected at levels greater than the applicable site cleanup goals (15A NCAC 2L .0202 groundwater quality standards (2L Standard)), during the monitoring events performed at the site on November 21-22, 2022, are summarized in the table below, along with the Gross Contamination Levels (GCLs). Exceedances of the cleanup goals are indicated in monitoring wells MW-1, MW-2, MW-5, MW-10, MW-11, MW-13, MW-14 and MW-15.
Table 2-1 Groundwater Analytical Results Summary
Contaminant GCL
(µg/L)
2L Standard
(µg/L) Well ID Concentration
(µg/L)
Benzene 5,000 1 MW-5 2.8
Methyl tert-butyl ether 20,000 20 MW-10 143
Naphthalene 6,000 6 MW-2 53.1 µg/L: micrograms per liter;
2.3 Current and Historical Extent of Groundwater Contamination
Based on the groundwater monitoring event for the reporting period, the current extent of groundwater contamination is defined by portions of the site with dissolved petroleum compounds in the shallow aquifer at concentration less than the 2L Standards, represented by monitoring wells MW-4, MW-6, MW-8 and MW-12, and with the exception of one portion of the methyl tert-butyl ether (MTBE) plume, by MW-3 and MW-9. Historical groundwater analytical data suggests the extent of dissolved petroleum compounds at concentrations greater than the 2L Standards has declined.
2.4 Water Supply Well Contaminant Concentrations
Dissolved groundwater contaminants were not detected at levels greater than the analytical method detection limit/2L Standard in two water supply well samples collected on December 8, 2022.
2.5 Remedial Actions
Per the Corrective Action Plan approved on February 8, 2017, natural attenuation was the selected remedial action.

2.6 Potential Receptors
As part of the May 2017 monitoring event, S&ME updated the potential receptor survey in the vicinity of the subject site. The vacant store building located on the subject property uses a water supply well located on the subject property. The well reconnaissance identified 10 water supply wells or suspected water supply wells on properties located within 500 feet of the source area. The nearest downgradient surface water body is a pond located approximately 300 feet northwest of the release location. Based on the USGS Topographic Map, an intermittent stream located approximately 200 feet from the source area flows east from the pond as an unnamed tributary of Haw River.

The previous gasoline UST system included three USTs with product lines supplying two fuel dispensers located approximately 75 feet from the nearest UST. The diesel UST system included one UST with a product line supplying one dispenser located approximately 15 feet from the UST. The USTs shared a common basin, but the gasoline and diesel dispensers were in separate locations. The apparent source of the release was the product lines and dispensers. Following removal of the leaking UST system, a new system was installed after the former UST basin was extended to accommodate the dimensions of the larger replacement tanks. The new gasoline system included one double-walled UST and new double-walled product lines. The diesel UST system was replaced with a new, double-walled UST, new double-walled product lines and dispenser pump. The new product lines were installed in a common trench. The UST system was placed into temporary closure during July 2021. The incident site location is shown on Figure 1, and the UST system locations are shown on Figure 2.
3.3 Non-UST Information
S&ME is not aware of information regarding past releases or the use of above ground storage tanks on the property. S&ME is not aware of non-UST, petroleum-product spills on the property, or of possible off-site sources.
3.4 Description of Release
Three 4,000-gallon gasoline USTs (Tank No. 1, 2, 3) and one 2,000-gallon diesel UST (Tank No. 4) were closed by removal on September 21, 2004. The UST systems were configured with one product line from the diesel UST to the diesel dispenser, and three product lines from the gasoline USTs installed within a common trench to the dispenser island. The gasoline lines entered a subgrade containment chamber at the gasoline dispenser island.
Petroleum-contaminated soil was excavated from the former UST basin in order to remove the former UST system. Based on the presence of petroleum odors noted in the tank excavation, the contractor segregated soil into a separate stockpile for reuse on the site. The analyses of soil samples obtained from the former tank basin backfill detected an elevated concentration of volatile total petroleum hydrocarbons (TPH) relative to the semi volatile TPH concentration, indicating the presence of a low boiling point fuel, such as gasoline. A 24-Hour Notice of a release was submitted to the North Carolina Department of Environmental Quality on September 28, 2004, following receipt of soil analytical results for the tank closure samples.
3.5 Site Characteristics
The subject site is currently vacant and was formerly utilized as a convenience store with retail fuel sales and a restaurant. The site topography slopes gently to the northeast, and the site is at a lower elevation than the adjoining property to the west. The west central portion of the property is developed with the single-story, masonry-framed store building, and with asphalt and concrete pavement systems east of the building. The UST basin underlies concrete pavement north of the building. The gasoline dispenser underlies a canopy located east of the building. The west and east portions of the property are landscaped grass yards, and the west property boundary is wooded. The sanitary septic tank is located south of the building and the sanitary drain field is located west of the building.

4.2 Groundwater Monitoring Event
On November 21 and November 22, 2022, S&ME completed groundwater a sampling event at the subject site, representing the fifth sampling event since the approval of the Corrective Action plan (CAP). Monitoring wells MW-1 through MW-17, and DW-1 were sampled, with the exceptions of monitoring wells MW-4 and MW-7. Figure 2 shows the location of the site’s monitoring wells.
Prior to purging, S&ME recorded in-site dissolved oxygen (DO) measurements for selected monitoring wells, as summarized on Table 3. DO values ranged from 0.47 milligrams per Liter (mg/L) to 0.80 mg/L in monitoring wells MW-1, MW-2, MW-3, MW-5 and MW-10. DO values ranged from 1.04 mg/L to 2.60 mg/L in monitoring wells MW-7, MW-9, and MW-15.
Monitoring wells MW-1, MW-4, MW-5, MW-6, MW-7, MW-8, and MW-10, MW-11, MW-12 and MW-14, were purged of approximately three well volumes with a disposable PVC bailer prior to collecting a groundwater sample. MW-2 and MW-3 were each purged with a bailer of less than three volumes. Monitoring wells MW-9, MW-15, MW-16 and MW-17, were purged to dryness with a disposable PVC bailer prior to collecting a groundwater sample. A grab sample was collected from MW-13 due to an insufficient volume of groundwater. Vertical extent monitoring well DW-1 was purged with a submersible pump. Each groundwater sample was transferred from a bailer, or from disposable tubing, by hand with a new pair of Nitrile gloves, and was placed directly into the laboratory provided sampling containers. The samples were submitted to Pace Analytical for laboratory analysis. The collected groundwater samples were analyzed for volatile organic compounds (VOCs), including oxygenates and ethanol, by EPA Method 6200B.
4.3 Water Supply Well Sampling Event
S&ME mailed Request for Permission to Sample Water Supply Well forms to the owners of properties with water supply wells identified within 500 feet of the subject site on November 18, 2022, including Map ID’s B, C, D, F, G, H and I, as shown on Table 1 and on Figure 3. Copies of the forms providing written or verbal permission to sample wells WSW-D and WSW-I are provided in Appendix II. Verbal permission to sample WSW-H was received after water supply well sampling was completed. On-site water supply well (WSW-A) was not sampled during the sampling event because the property was vacant.
On November 18, 2022, S&ME personnel sampled active potable water supply well WSW-D and WSW-I after allowing each well to purge for approximately 15 minutes prior to sampling. The groundwater samples and one field blank sample were placed in laboratory-supplied containers, placed in a cooler on ice, and shipped under standard chain-of-custody procedure to Pace Analytical for analysis of VOCs, including oxygenates and ethanol, by EPA Method 6200B. The Water Supply Well Sampling Forms are provided in Attachment II.
4.4 Summary of Remedial Actions
According to the CAP, natural attenuation is the selected remedial action.

4.5 Regional and Site Geology and Hydrogeology
4.5.1 Regional Geology
The subject site is located in the Carolina Slate Belt hydrogeologic province of the Piedmont Physiographic Province of North Carolina. The area is underlain by metamorphic granitic rock as described on the 1985 Geologic Map of North Carolina.
Soils in this region are typically composed of residual weathering products of the underlying parent rocks. A transitional zone exists between the unweathered bedrock and the overlying soil. This regolith is primarily saprolite, a clay-rich residuum derived from the in-situ weathering of the underlying bedrock.
4.5.2 Site Geology
During previous site assessment, S&ME observed soil generally consisting of clay silt, underlain by silt or sandy silt, underlain by silty sand or sand. Bedrock was not encountered during installation of shallow monitoring wells on the site, at depths up to 26.7 ft-bgs. Bedrock was encountered at an approximate depth of 29 ft-bgs during installation of vertical extent monitoring well DW-1.
4.5.3 Hydrogeology
Based on the groundwater occurrence data collected on November 21 and November 22, 2022, divergent groundwater flow conditions shown on Figure 4 appear to range generally to the west and north proximal to the UST basin at a horizontal hydraulic gradient of 0.011. Groundwater flow to the northeast was observed in the vicinity of the gasoline dispenser at a horizontal hydraulic gradient of 0.017 feet per foot. Based on the relative groundwater elevations observed in shallow monitoring well MW-6 and vertical extent monitoring well DW-1, on November 22, 2022, a downward vertical hydraulic gradient of 0.117 feet per foot was observed. Groundwater occurrence ranged from approximately 0.8 feet to 3.1 feet lower in elevation on November 21-22, 2022, relative to April 27, 2022.
5.0 Evaluation of Assessment Information

January 4, 2023 9
5.2 Groundwater Sampling Event
Multiple petroleum compounds were reported in the samples collected at concentrations greater than the corresponding 2L Standards. As shown in Table 3 and on Figure 5, dissolved constituent concentrations greater than the 2L Standard were reported in the following monitoring wells. Concentrations greater than the corresponding GCLs were not reported.
• Benzene: MW-2, MW-5
• Methyl tert-butyl ether (MTBE): MW-10, MW-11, MW-13, MW-14, MW-15
• Naphthalene: MW-1, MW-2, MW-5 Since the CAP approval in 2017, similar dissolved MTBE concentrations have been observed during subsequent monitoring events in monitoring well MW-13. Constituent concentrations continue to decrease in monitoring wells MW-1, MW-2, MW-3, MW-5, MW-10, MW-11, MW-12 and MW-15. 2L exceedances have not been observed in off-site monitoring well MW-14 since 2009; however, MTBE was reported at a concentration of 46.4 micrograms per Liter (µg/l) in the sample collected on November 22, 2022. Historical groundwater concentrations are shown in Table 4. Graphs illustrating historical concentrations of benzene, MTBE and naphthalene in selected monitoring wells are included in Appendix III.
Isoconcentration Contour figures for benzene and MTBE, representing groundwater quality conditions on November 22, 2022, are presented as Figure 6 and Figure 7, respectively. With the exception of MTBE reported in off-site monitor well MW-14, Figure 6 and Figure 7 indicate diminished horizontal extents for benzene and MTBE, relative to the Isoconcentration Contour figures representing the April 27, 2022, monitoring event. The laboratory analytical report is included in Appendix IV.
The horizontal extent of the dissolved constituent plume exceeding the 2L Standards is defined by monitoring wells MW-4, MW-6, MW-8 and MW-12, and with the exception of one portion of the methyl tert-butyl ether (MTBE) plume, by MW-3 and MW-9. The vertical extent of the dissolved constituent plume exceeding the 2L Standards is defined by vertical extent monitoring well DW-1.
5.3 Contaminant Mass Calculations in Soil and Groundwater
The following summarizes the calculations made to determine the contaminant mass of petroleum in the soil and groundwater. S&ME has not completed additional soil assessment at the site since completion of the Comprehensive Site Assessment (CSA) dated June 17, 2011.
5.3.1 Baseline Petroleum Contaminant Mass Calculation
The spreadsheets included in Appendix V were used to calculate the initial petroleum volume in soil, based on the data included in the CSA, the petroleum volume dissolved in groundwater at the time of completion of the CAP, and the petroleum volume dissolved in groundwater represented by the current monitoring event.
Based on the excavation and assessment volume calculations described in the Monitoring Report dated June 6, 2022, the baseline volume of gasoline in soil was approximately 168 gallons. For groundwater, S&ME used the estimated extent of benzene impacts from the March 19, 2016, Benzene Isoconcentration Contour Map submitted

with the Corrective Action Plan to estimate the volume of contaminated groundwater. The calculated total volume of gasoline in groundwater at the time of the CAP was estimated to be approximately 1.2 gallons.
5.3.2 Current Petroleum Contaminant Mass Calculation
The volume of contaminated groundwater was calculated based on an assumed effective porosity of 0.3, which was used in the CSA to calculate groundwater velocity. The Isoconcentration contour lines for 1 µg/l were used, along with an estimated depth of contamination at 12 feet. This estimate is based on the approximate depth to groundwater (17 feet +/-) and depth to bedrock observed during installation of vertical extent monitoring well DW-1 (approximately 29 feet below ground).
The total lateral extent of petroleum impacts in groundwater, based on the estimated 1 µg/l isoconcentration contour was 3,350 square feet, as shown on Figure 6. The estimated concentration used for the area within 1 µg/l was the average 1 µg/l and the highest reported benzene concentration (2.8 µg/l) in MW-5). From this, a calculation of total milligrams of benzene was converted to gallons of benzene. EPA documents estimate that gasoline contains approximately 1% of benzene by volume. The calculated total volume of gasoline in groundwater on November 22, 2022, was estimated to be approximately 0.023 gallons.
The data suggests the volume of gasoline in groundwater has declined from the calculated baseline volume of 1.2 gallons to the current calculated volume of 0.023 gallons, or a reduction of about 98%. The lateral extent of benzene impacts in groundwater, at a concentration greater than 1 µg/l, has reduced from a calculated baseline area of 9,640 square feet to a calculated area of 3,350 square feet, or a reduction of about 65%.
5.4 Cleanup Levels Achieved
• Soil (soil-to-groundwater maximum soil contaminant concentrations) No
• Groundwater (2L standard concentrations) No
• Free Product (0.01 feet) Yes
6.0 Conclusions
Analytical results for groundwater samples collected from monitoring wells during the November 2022 monitoring event indicates multiple dissolved petroleum compounds in the groundwater at concentrations greater than North Carolina groundwater quality standards. Based on historical analytical results for dissolved compounds, constituent levels are less than the maximum levels observed, and the dissolved constituent plume is declining. Natural attenuation monitoring activities should continue until the target cleanup goals are met. Cleanup progress milestones will be calculated after the next groundwater sampling event.
The concentration of MTBE increased in downgradient, off-site monitoring well MW-14 on November 22, 2022, relative to values from monitoring events performed subsequent to March 2009. MW-14 is located proximal to water supply well D located on a north adjacent property at 2915 Lake Drive, Burlington, NC. VOCs were not detected in a water sample collected from water supply well D on December 8, 2022. Based on the current groundwater quality data and the CAP, we recommend continuation of periodic monitoring well sampling and water supply well sampling activities to document natural attenuation of target compounds.

7.0 Statement of Qualification
1 A due date for the performance report was specified by the NCDEQ. N/A
2 Was any required information from the above template missing from this report? NO

3 If applicable, will any of the proposed attenuation milestones under the schedule approved in the Corrective Action Plan not be met? (within a reasonable margin of error)

N/A
Attenuation milestones were not required when the Corrective Action Plan was prepared.
4 Does any known or suspected source zone soil contamination or free product remain outside of the assessed area that could be inhibiting natural attenuation? NO
5 Has there been an unexpected increase in contaminant mass sufficient to suggest a potential new release from a separate onsite or offsite source? NO

1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
