Re: Ground Water Sampling Activities
Red Apple Mart #15
1109 US Highway 64 East
Plymouth, North Carolina
Washington County
Incident Number: 11890
GRI Project Number: 2970

Dear Mr. Edwards;

Geological Resources, Inc. (GRI) presents the results of the ground water sampling activities at the Red
Apple Mart #15 site in Plymouth, North Carolina. The activities were conducted in response to the
September 2020 email conversation and the September 25, 2020 correspondence from the NCDEQ.

On October 14, monitoring wells MW-4, MW-13 and MW-14 were gauged, purged and sampled. Depth
to water in the monitoring wells were 10.15, 11.39, and 11.23 feet below the top of casing in MW-4,
MW-13 and MW-14, respectively. Ground water samples were submitted for analyses of VOCs plus
oxygenates by EPA Method 6200B. A Site Location Map and Site Map have been included as Figures 1
and 2.

Please see the attached laboratory report for the results of the October 2020 ground water sampling
event. The Maximum Allowable Concentrations specified in T15A NCAC 2L.0202 were below the
concentrations of benzene, toluene, ethylbenzene, xylenes, naphthalene, tert-Amyl alcohol, tert-Butyl
alcohol, methyl chloride, isopropylbenzene, methylene chloride, n-propylbenzene, 1,2,4-
trimethylbenzene and/or 1,3,5-trimethylbenzene reported in the ground water samples collected from
MW-4, MW-13 and MW-14. None of the reported contaminant concentrations exceeded the Gross
Contamination Levels. A copy of the laboratory report is included as Appendix A.
