1.0 INTRODUCTION

Excel Civil & Environmental Associates, PLLC (Excel) was contracted Sam’s Mart, Incorporated
to complete site check activities for Sam’s Mart 7 located at 2630 Beatties Ford Road within the
city limits of Charlotte, Mecklenburg County, North Carolina (refer to Figure 1). The site check
was completed on February 20, 2024. A prior site check was completed for the property in
August and September of 2017 with soil samples collected adjacent to the underground storage
tank area.

The site check activities completed by Excel included the installation of two (2) temporary
monitoring wells with associated laboratory analysis and the completion of this report.

2.0 BACKGROUND INFORMATION

2.1 Area of Investigation

The facility is located on the eastern side of Beatties Ford Road within the city limits of
Charlotte, North Carolina. Interstate I-85 tracks in an east-west direction running along the
northern perimeter with Beatties Ford Road tracking north-south along the western perimeter of
the subject property. Surrounding the property to the west are commercial properties; to the
south and east are churches.

Additional structures located on the property at the time of this assessment consists of a one-
story building, canopy, USTs and associated fuel-dispensing system in addition to a car wash to
the north of the UST pit (refer to Figure 2).

The subject site is located in the Inner Piedmont Physiographic Province of North Carolina; the
elevation in the area of investigation is approximately 770-feet above mean sea level (see
Figure 1). The northern, southern and eastern sections of the site are covered by concrete.
The general topography of the site slopes to the north-northeast with surface drainage generally
following the topography of the site and discharging primarily in a northeast direction.

A release was suspected by the responsible party after a precision tank test determined a hole
in the UST system in September of 2023. The tank was subsequently drained out and repaired.
Based on a site check already indicating soil impacts from a previous release, Excel
coordinated with DEQ for installation of two temporary monitoring wells on the eastern and
western sides of the basin. The temporary monitoring wells were installed on February 20, 2024
and analyzed for Volatile Organic Compounds, MADEP VPH, EDB, and lead. The groundwater
samples collected from TW-1 indicate various constituents over the NCAC 2L standards. The
groundwater samples collected from TW-2 indicate various constituents over the NCAC 2L
standards and benzene exceeding the NCDEQ Gross Contamination Levels (GCLs).

3.0 GEOLOGIC FRAMEWORK
3.1 Regional Geology
Geologically, the subject site is located in the Inner Piedmont Physiographic Province of North
Carolina, specifically the Milton Belt. The 1985 Geologic Map of North Carolina indicates this
area as being underlain by granite rock characterized by being massive to weakly foliated and
containing horblende.
3.2 Site Geology
During the completion of the soil borings in August and September 2017, the soils observed
during drilling activities surrounding the USTs, dispenser islands, and associated piping were
observed to consist of predominantly concrete and ABC stone from grade to 2-fbgl and reddish
brown to orange silty clay from 2-fbgl to approximately 15-fbgl. Soil borings were advanced to a
maximum depth of approximately 15-fbgl. The type of soils observed at the drilling locations
appear consistent with the surficial soils common for this area.
4.0 FIELD ACTIVITIES
Two temporary monitoring wells were completed by coring through the concrete parking lot
immediately adjacent to the UST pit on the eastern and western sides and installing two
temporary monitoring wells to a total depth of 40 deet. Groundwater samples were collected
from each well for laboratory analysis to assess groundwater conditions at the site. The
temporary monitoring well construction logs can be found in Appendix A. The locations of the
temporary monitoring wells are shown on Figure 2.
The samples were stored on ice and transported under chain-of-custody procedures to
Waypoint Analytical in Charlotte, North Carolina for analysis by the following methods as
applicable:
Volatile Organic Compounds by EPA Method 6200B,
MADEP VPH,
EDB by EPA Method 8011 and;
Lead by EPA Method 6010D.
5.0 LABORATORY ANALYSIS
Excel collected a total of two (2) groundwater samples (TW-1 and TW-2) to complete site check
activities which were analyzed for Volatile Organic Compounds by EPA Method 6200B,
MADEP VPH, EDB and Lead. The groundwater samples collected from TW-1 indicate various
constituents over the NCAC 2L standards. The groundwater samples collected from TW-2
indicate various constituents over the NCAC 2L standards and benzene exceeding the NCDEQ
Gross Contamination Levels (GCLs).

The laboratory analytical results are summarized in Table 2 and are graphically presented in
Figure 3. The analytical laboratory report for the groundwater sampling activities and
associated chain of custody (COC) forms are presented in Appendix B.
6.0 SUMMARY AND RECOMENDATIONS
Excel collected a total of two (2) groundwater samples (TW-1 and TW-2) to complete site
check activities which were analyzed at for Volatile Organic Compounds by EPA Method
6200B, MADEP VPH, EDB and Lead. The groundwater samples collected from TW-1
indicate various constituents over the NCAC 2L standards. The groundwater samples
collected from TW-2 indicate various constituents over the NCAC 2L standards and
benzene exceeding the NCDEQ Gross Contamination Levels (GCLs) (refer to Table 1);
Based on the information in this report, Excel recommends completion of a Limited Site
Assessment at this time to confirm the GCL exceedances with a permanent Type II
monitoring well (refer to Figure 4).
