Re: Groundwater Sampling Results
Former Circle K Store #2723015
3300 Camden Road
Fayetteville, Cumberland County, North Carolina
NCDEQ Incident No. 49159
NCDEQ Ranking H155D

Dear Mr. Currie:
On behalf of Circle K Stores Inc., ATC Associates of North Carolina, P.C. (ATC) has prepared this letter
report to provide a summary of the groundwater sampling event performed at the site, as approved in TA-2.
A site location map is provided as Figure 1 and a site map is provided as Figure 2.

Groundwater Sampling
On November 27, 2023, ATC collected a static water level measurement from monitoring well MW-1A.
ATC attempted to locate montioring well MW-15; however, the well could not be located. Light
non-aqueous phase liquid (LNAPL) was not measured in monioring well MW-1A on this date. The depth
to water measurement was collected using an electronic oil/water interface probe (13.61 feet below ground
surface. Due to limited data points, a groundwater elevation contour map could not be generated at this
time.

On November 27, 2023, a groundwater sample was collected from monitoring well MW-1A. As previously
noted, monitoring well MW-15 could not be located. The monitoring well was purged prior to sampling
by removing a minimum of three well volumes of water from the well. After allowing sufficient time for
recharge, a representative groundwater sample was collected from the well using a new, disposalbe Teflon
bailer. Upon collection, the groundwater sample was placed into laboratory-approved containers, packed
in ice, and delivered under chain-of-custody to SGS North America in Scott, Louisiana, for analyses. The
groundwater samples were analyzed by Environmental Protection Agency (EPA) Method 6200B to include
ethanol and oxygenates.
