Dear Ms. Lepard

On behalf of Pilot Travel Centers, Inc. (Pilot), 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. A site map
is provided as Figure 1.

LNAPL Check
On October 18, 2022, ATC personnel measured monitoring wells MW-15, MW-21, MW-26A, and MW-28
for the presence of light non-aqueous phase liquid (LNAPL). On this date, LNAPL was measured as
follows:

• Monitoring well MW-15: 0.52 feet
• Monitoring well MW-21: 1.10 feet
• Monitoring well MW-26A: 3.01 feet
• Monitoring well MW-28: 0.37 feet

Groundwater Sampling
On October 18, 2022, ATC collected static water level measurements from monitoring wells MW-A1A,
MW-3, MW-4, MW-5, MW-19, MW-20, MW-25, and MW-27. LNAPL was not measured in these wells
on this date. The depths to water measurements were collected using an electronic oil/water interface probe.
Groundwater elevation data is provided in Table 1. A groundwater elevation contour map is provided as
Figure 2. It appears groundwater flows southwest across the site.

On October 18,2022, groundwater samples were collected from wells MW-AlA, MW-3, MW-4, MW-5,
MW-19, MW-20, MW-25" and MW-27, following standard sampling protocols. The groundwater samples
were collected into laboratory-approved containers, packed in ice, and delivered under chain-of-custody to
SGS North America, Inc. (SGS) in Scott, Louisiana, for analyses. The groundwater samples collected from
monitoring wells MW-AIA, MW-3, MW-4, MW-5, and MW-25 were analyzed by Environmental
Protection Agency (EPA) Method 62008 to include ethanol and oxygenates. The groundwater samples
collected from monitoring wells MW-19, MW-20, and MW-27 were analyzed by EPA Method 602 and
EPA Method 625 (PAHs only).
Laboratory analytical results of the groundwater sample collected from monitoring well MW-5 detected a
dissolved benzene concentration above its established Gross Contaminant Level (CCL). LNAPL was
measured in monitoring wells MW-15. MW-21, MW-26A, and MW-28. A summary of the groundwater
analy'tical data is provided in Table 2. Dissolved target compound concentrations, exceeding CCLs, is
provided as Figure J. A copy of the laboratory analytical report is included as Attachment I.
Sincerely.

The final report for SGS Job LA84462 has been amended from the original. This report replaces in its entirety any
previously submitted copy. SGS sample LA84462-2 was analyzed at a 1x and a 10x dilution. Original report only
includes the target compounds reported from the 10x dilution. The attached revised report includes both analytical
runs. The attached report incorporates these revisions.

Please contact me at 337-237-4775 if I may be of further assistance in this matter, or if you have any further
