Re: Groundwater Sampling Results
Former Tilley’s Superette
1710 Union Grove Road
Lenoir. Caldwell County, North Carolina
NCDEQ Incident No. 28466
NCDEQ Ranking H155D

Dear Mr. Murphy:
On behalf of Cary Oil Co., Inc. (Cary Oil), 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-43 and as requested in your letter dated January 24, 2023. A site location map is provided as Figure
1 and a site map is provided as Figure 2.

Groundwater Sampling
On June 13, 2023, ATC collected a static water level measurement from monitoring wells MW-1, MW-2,
MW-3, MW-9, and MW-12. Light non-aqueous phase liquid (LNAPL) was not measured in the wells on
this date. The depths to water measurements were collected using an electronic oil/water interface probe.
Groundwater elevation data are provided on Table 1. A groundwater elevation contour map is provided as
Figure 3. It appears groundwater flow is toward the southwest across the site.

On June 13, 2023, groundwater samples were collected from monitoring wells MW-1, MW-2, MW-3,
MW-9, and MW-12. The monitoring wells were purged prior to sampling by removing a minimum of three
well volumes of water from each well. After allowing sufficient time for rechrage, a representative
groundwater sample was collected from each well using a new, disposable Teflon bailer. Upon collection,
the groundwater samples were 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.

ThelaboratoryanalyticalresultsofthegroundwatersamplescolIectedr.o,*ffi,
MW-2, MW-3, and MW-I2 detected target compound concentrations above established 2L Standards.
Dissolved benzene was detected above its established Gross Contaminant Level (GCL) in the groundwater
sample collected from montioring well MW-2. Dissolved methyl tert-butyl ether (MTBE) was detected
above its established GCL in the groundwater samples collected from monitoring wells MW-2 and MW-3.
A summary of the groundwater analyical data is provided in Tsble 2. Dissolved contaminants of concern
are depicted on Figure 4. A copy of the laboratory analytical report is included as Attochment I.
ATC recommends the performance of a Mobile Multi-Phase Extraction (MMPE) event to address the
continued presence of dissolved contaminants above established GCLs and2L Standards.
If you have any questions or require additional information, please contact our office at [phone].
Sincerely,
ATC Associates of North Caroli
