This Pre-CAP - Initial Groundwater Monitoring Report has been performed under the NCDEQ Task
Authorization (TA) preapproval TA #48320-02. A copy of the preapproval is attached in Appendix A.
D.1 UST AND AST OWNER AND OPERATOR INFORMATION
The UST and dispenser islands are located as shown in Figure 2. The tank is owned and operated by
M.M. Fowler, Inc. Site History – UST Owner/Operator and Other Responsible Party Information has
been summarized in Table 1. The responsible party for the documented UST release, NCDEQ Incident #48320, is M.M. Fowler, Inc.
D.2 UST SYSTEM INFORMATION
Petroleum fuels at the station are currently dispensed from three underground storage tanks (USTs) of
single wall fiberglass reinforced plastic (FRP) construction. The USTs are used for petroleum retail purposes and were reportedly installed on January 1, 1998. According to the NCDEQ registered tank
database the UST system consists of one 15,000-gallon capacity regular gasoline UST, one 8,000 gallon capacity diesel UST, and one 8,000-gallon capacity premium gasoline UST. Site History – UST
System and Other Release Information has been summarized in Table 2.
D.3 NON-UST SYSTEM INFORMATION
No ASTs are associated with the site.
D.4 RELEASE INFORMATION
Investigation for a potential release from the existing underground storage tank (UST) system was initiated following a compliance inspection performed by the North Carolina Department of
Environmental Quality (NCDEQ) on December 21, 2021. A Site Check was performed to investigate for a suspected release in and around the premium UST spill bucket which failed a hydrostatic test.
The site check investigative activities and resultant groundwater quality results were included in a report entitled “Site Check Report: Battleground Family Fare BP #112” submitted to the NCDEQ on
March 15, 2022. Based on the review of the report the NCDEQ assigned Incident #48320 to the release and issued Notice of Regulatory Requirements (NORR) correspondence dated March 31,
2022 requesting the performance of a Limited Site Assessment (LSA) – Phase I Report.
The assessment activity for Incident #48320 has been documented in the following reports that were
submitted to the NCDEQ:

• Site Check Report: Battleground Family Fare BP #112, EMS Environmental, Inc. (EMS), March 15, 2022.
• Limited Site Assessment – Phase I: Battleground Family Fare BP #112, EMS, June 24, 2022.
• Limited Site Assessment - Phase I and II, EMS, November 16, 2022.

The results of the investigations are summarized below:
During Site Check activities, soil samples could not be obtained directly beside the premium
gasoline spill bucket. As a result, EMS installed a groundwater monitoring well (MW-1) down gradient and adjacent to the UST basin in order to collect a groundwater sample for volatile organic
compounds.
Analysis by EPA Method 6200B with oxygenates revealed estimated or detectable concentrations of
Benzene, Toluene, Ethylbenzene, Total Xylenes, 1, 2, 4-Trimethylbenzene, 1, 3, 5- Trimethylbenzene, and n-Propylbenzene in monitoring well MW-1. No target oxygenates were
observed to be present. Analysis by MADEP VPH revealed concentrations of petroleum hydrocarbon fractions C5-C8 aliphatics at 455 ug/L, C9-C18 aliphatics at 213 ug/L, and C9-C22
aromatics at 270 ug/L. These concentrations were observed to be above the NCAC 2L GWQS of 400 ug/L for the C5-C8 aliphatics fraction, and above the 200 ug/L C9-C22 aromatics fraction,
respectively. Based on the exceedances, a UST-61 24-Hour Release and UST Leak Reporting form was prepared and submitted to the NCDEQ on March 11, 2022. Groundwater analytical results are
summarized on Table 3.
A potential receptor survey was initially performed on April 14, 2022 and was updated following telephonic communication on May 24, 2022 with a representative of the City of Greensboro Water
Resources Department Additional information and with the Guilford County DHHS on June 24,
2022. A total of five water supply wells were identified within 1,000 feet of the site as a result of the receptor survey. All of the potable water supply wells are located on Four Farms Road between 375
feet and 625 feet to the west-southwest. The summary of potential receptors is summarized in Table
4 and shown on Figure 3.
Adjacent property ownership, contact information, and zoning were researched through the Guilford County Geographic Information System (GIS). Adjacent property information has been updated to
reflect current property owner status as of February 2022. The summary of adjacent property information is tabulated in Table 5 and shown on Figure 4.
Surface water was identified at approximately 575 feet south of the site UST basin (Figure 1). The surface water body has been identified as an unnamed tributary (UT) to Horse Pen Creek which
ultimately empties into a portion of Lake Brandt. Horse Pen Creek (Stream Index 16-11-5(2) is designated as a Water Supply (WS)-III, Nutrient Sensitive Water (NSW). Critical Area (CA) surface
water classification from US Highway 220 to Lake Brandt (Reedy Fork).
Soil samples were collected during the LSA investigation in the vicinity of monitoring well MW-1.
Based upon historical soil sample result summaries, the soil quality for the compound Benzene was determined to be above the Soil to Groundwater MSCC but less than the Residential MSCC. The
sample was collected at 30 feet below ground surface and may represent smear zone soil. No other detected target compound exceeded the Soil to Groundwater MSCC. Historical soil sample result
summaries and soil sample location maps have been included in Appendix B.

E.6 SUMMARY OF SOIL, GROUNDWATER, SURFACE WATER AND FREE PRODUCT ASSESSMENT
INFORMATION ACQUIRED TO DATE
Summaries of previous and current assessment data are provided in data tables included in this report and in Appendix B.
E.7 GEOLOGY AND HYDROGEOLOGY OF THE SITE
The following Sections E.7.1 and E.7.2 present the geology and hydrogeology of the site.

12

E.7.1 Regional and Site Geology
According to the Geologic Map of North Carolina (Brown et al, 1985), the site is located within the Carolina Slate Belt of the Piedmont Physiographic Province. Subsurface geology in the site vicinity
has been mapped as CZg and is described as metamorphic granitic rock, late Proterozoic to late Cambrian aged. The unit is further described as megacrystic, well foliated; locally contains
hornblende.
The general site geology has been characterized through observations made during the
advancement of soil borings and monitoring well installations. The soil borings for MW-1 through MW-5, and SB-1, encountered a reddish brown sandy clay with minor amounts of silt was
encountered up to 20 feet BGS prior to transitioning to a lighter brownish grey micaceous sandy clay with varying amounts of silt that extended to the boring termination depth of 40 feet BGS. Bedrock
was not encountered to a depth of 40 feet bgs.
E.7.2 Site Hydrogeology
Data gathered during the reporting period was used to calculate relative water table elevations. Areas
of equal water table elevations were contoured to estimate the apparent local groundwater flow direction as shown on Figure 5. Review of Figure 5 indicates that the shallow groundwater flow direction is primarily oriented towards the east-northeast over a hydraulic gradient of 0.001 feet/foot
from MW-1 to MW-3.
Formal hydrogeologic investigations have not been performed to date.
E.8 SOIL, GROUNDWATER, SURFACE WATER, AND FREE PRODUCT ASSESSMENT INFORMATION
E.8.1 Maximum Extent of Soil Contamination
Soil samples were collected during the LSA investigation in the vicinity of monitoring well MW-1. Based upon historical soil sample result summaries, the soil quality for the compound Benzene was
determined to be above the Soil to Groundwater MSCC but less than the Residential MSCC. The sample was collected at 30 feet below ground surface and may represent smear zone soil. No other
detected target compound exceeded the Soil to Groundwater MSCC. Historical soil sample result summaries and soil sample location maps have been included in Appendix B.
Based upon the soil sample results, additional assessment, re-evaluation, and/or remediation of the soils above the Soil to Groundwater may not be required for this site.
E.8.2 Maximum Historical Extent of Groundwater Contamination
Historical EPA Method 6200B with oxygenates, total lead, EDB by EPA Method 504.1, and MADEP VPH-EPH analytical results are summarized in Table 3. Historically, the highest estimated or
detectable concentrations of dissolved phase petroleum hydrocarbon compounds in excess of the NC 2L GWQS have occurred in MW-1.
A plume of dissolved phase compounds above the 15A NCAC 2L GWQS standards has historically been situated near MW-1 and is centered at the UST basin area. Horizontal delineation has primarily
been achieved for target compounds with the exception of benzene west of MW-5.
Vertical delineation has not been evaluated at this site.

E.8.3 Current Extent of Groundwater Contamination
A plume of dissolved phase hydrocarbons is present on the site with concentrations that exceed the 15A NCAC 2L GWQS.
Laboratory analysis of samples collected on March 22, 2023 revealed the presence of the following compounds with concentrations that exceeded the site applicable 15A NCAC 2L GWQS:
• Benzene (1 ug/L): MW-1 (930 ug/L) and MW-5 (4.7 ug/L)
• Toluene (600 ug/L): MW-1 (2,000 ug/L)
• Total Xylenes (500 ug/L): MW-1 (4,500 ug/L)
• 1,2,4-Trimethylbenzene (400 ug/L): MW-1 (830 ug/L)
• n-Propylbenzene (70 ug/L): MW-1 (100 ug/L)
• Naphthalene (6 ug/L): MW-1 (150 ug/L)
• Tert-Amyl-Alcohol (40 ug/L): MW-1 (estimated 390 ug/L), and MW-5 (44 ug/L)

EPA Method 6200B with oxygenates, total lead, EDB by EPA Method 504.1, and MADEP VPH-EPH analytical results are summarized in Table 3. The detectable extent of the compounds on the site
are shown on the attached Figures 6 through 10.
E.8.4 Comparison of Current and Historical Groundwater Contamination
The levels of dissolved phase compounds have increased in MW-1 since the last sample event and
have remained consistent in other site wells. Horizontal delineation has primarily been achieved in all geographic directions with the exception of benzene west of MW-5.
E.8.5 Natural Attenuation Parameter Testing
Field measurements for pH, specific conductivity, temperature, ORP, and dissolved oxygen, were
attempted to be monitored on March 22, 2023 from all site monitoring wells. However, due to a malfunctioning instrument the measurements were not collected this period.
The historical results are summarized in Table 7 and discussed below.
Dissolved Oxygen (DO)
Concentrations of DO above 0.5 mg/L generally indicate the hydrocarbons are degrading in an oxidizing environment. Historical concentrations in shallow wells on October 25, 2022 ranged from
3.35 mg/L in MW-2 to 7.68 mg/L in MW-4. All monitoring wells were above DO concentrations of 0.5 mg/L appearing to indicate that DO conditions in the shallow groundwater are into the aerobic
condition range.
Temperature
Temperature showed little variation in the monitoring wells. Historical temperature in shallow wells on October 25, 2022 ranged from 17.33 degrees centigrade (OC) in MW-1 to 17.83 OC in MW-3.

14

Specific Conductivity
Historical specific conductivity in shallow wells on October 25, 2022 ranged from 0.112 millisiemens per centimeter (mS/cm) in MW-2 to 0.328 mS/cm in MW-3. Conductivity values above 0.100 mS/cm
indicate that the transfer of electrons is favorable in the subsurface.
ORP
ORP (oxidation reduction potential) measures the oxidizing or reducing capacity of groundwater to
either release or accept electrons from chemical reactions. Historical ORP values in the shallow groundwater ranged from 11.6 millivolts (mV) in MW-2 to 31.8 mV in MW-4.
pH
Values of pH that range from 6-8 are generally conducive for natural attenuation processes. Historical
units of pH in shallow wells on October 25, 2022 ranged from 5.04 in MW-1 to 5.93 in MW-2. Favorable conditions for microbe activity do not appear to be present based on the measured pH
values.

E.9 CLEANUP STANDARDS
• The current soil regulatory standards are the lower of the Soil to Groundwater and
Residential MSCCs.
• The groundwater remedial standards are the 15A NCAC 2L GWQS.
Currently, these standards appear to have been met for soil but not for groundwater.

F FREE PRODUCT REMOVAL
Free product is not associated with this site.

G SOIL REMEDIATION
Soil has not been remediated at this site. The results of soil quality sampling around the UST basin has revealed the presence of limited areas of adsorbed phase petroleum hydrocarbon impact above
the applicable lower of the Soil to Groundwater MSCCs (Appendix B) and may represent smear zone soil.

H GROUNDWATER REMEDIATION
Groundwater remediation has not occurred at this site and may be required to lower the
concentration of benzene to below the 15A NCAC 2L GWQS. Aggressive Vapor Fluid Recovery (AFVR) or Mobile Multi Phase Extraction (MMPE) techniques may be useful in lowering groundwater
concentrations to below the 15A NCAC 2L GWQS.

15

I CONCLUSIONS
The following is a summary and conclusion of the site activities performed during the period under approved Task Authorization #20828-02:
• Horizontal groundwater delineation was performed through the installation of MW-5.
• A plume of dissolved phase hydrocarbons appears to be centered at MW-1 near the UST
basin area. Horizontal delineation has primarily been achieved for all target compounds to the NCAC 2L GWQS with the exception of benzene west of MW-5.
• Vertical delineation has not been evaluated at this site.
• Phase separated hydrocarbons were not observed to be present and all target compounds observed to be present are less than the GCLs this period.
• AFVR and/or MMPE may reduce dissolved phase groundwater concentrations to below the 15A NCAC 2L GWQS, if necessary.

Receipt
The samples were received on 3/22/2023 1:45 PM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.0°C
GC/MS VOA
Method SM6200_B: The method blank for 752-2119 contained Chloroform above the reporting limit (RL). None of the samples associated
with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not performed. MW-1
(752-4725-1), MW-2 (752-4725-2), MW-3 (752-4725-3), MW-4 (752-4725-4), MW-5 (752-4725-5) and (MB 752-2119/9)
Method SM6200_B: The continuing calibration verification (CCV) associated with batch 752-2119 recovered above the upper control limit
for Dichlorodifluoromethane, Vinyl chloride, Chloroethane, Trichlorofluoromethane and 1,1-Dichloroethene. The samples associated with
this CCV were non-detects for the affected analytes; therefore, the data have been reported. MW-1 (752-4725-1), MW-2 (752-4725-2),
MW-3 (752-4725-3), MW-4 (752-4725-4), MW-5 (752-4725-5) and (CCVIS 752-2119/2)
Method SM6200_B: The closing continuing calibration verification (CCVC) associated with batch 752-2119 recovered above the upper
control limit for Vinyl chloride, Chloroethane and Trichlorofluoromethane. The samples associated with this CCV were non-detects for the
affected analytes; therefore, the data have been reported. MW-1 (752-4725-1), MW-2 (752-4725-2), MW-3 (752-4725-3), MW-4
(752-4725-4), MW-5 (752-4725-5) and (CCVC 752-2119/24)
Method SM6200_B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical batch 752-2119
recovered outside control limits for the following analytes: Dichlorodifluoromethane, Vinyl chloride, Chloroethane, Trichlorofluoromethane
and Ethanol. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been
reported. MW-4 (752-4725-4), MW-5 (752-4725-5), (LCS 752-2119/5) and (LCSD 752-2119/6)
Method SM6200_B: The following sample was diluted to bring the concentration of target analytes within the calibration range: MW-1
(752-4725-1). Elevated reporting limits (RLs) are provided.
Method SM6200_B: An expired standard was used as a component of the MW-1 (752-4725-1), MW-2 (752-4725-2), MW-3 (752-4725-3),
(CCVC 752-2119/24), (CCVIS 752-2119/2) and (MRL 752-2119/4). The lab will re-certify the standard to extend the expiration date until a
new shipment arrives.
Method SM6200_B: The initial calibration curve analyzed in batch 752-2119 was outside acceptance criteria for Chloromethane,
1,2,3-Trichlorobenzene and Naphthalene. The 6200B curve %RSD passed; however, these compounds did not meet the %error read
back criteria.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Hydrocarbons
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC Semi VOA
Method 504.1: Excess sediment found on sample bottom, transfered to another 40 ml vial.MW-5 (752-4725-5)
Method 504.1: Surrogate recovery for the following sample was outside the upper control limit: MW-5 (752-4725-5). This sample did not
contain any target analytes; therefore, re-extraction and/or re-analysis was not performed.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Metals
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
