Re: Groundwater Sampling Activities

NCDEQ Incident No. 17265

Dear Ms. Price:

On behalf of Circle K Stores, Inc., ATC Associates of North Carolina, P.C. (ATC) has prepared this
letter to provide a summary of groundwater sampling activities conducted at the referenced facility
(as approved in task authorization TA-52).

Groundwater Sampling – Monitoring Wells
On April 6, 2022, ATC collected a static water level measurements from monitoring wells MW-6
and MW-11. The depths to water measurements were collected using an electronic oil/water
interface probe. Current groundwater elevation data are included in Table 1. A site map depicting
the location of the monitoring wells is provided in Figure 1.

On April 6, 2022, groundwater samples were collected from monitoring wells MW-6 and MW-11.
The groundwater samples were collected into laboratory-approved containers, packed in ice and
delivered under chain-of-custody to Waypoint Analytical (Waypoint) of Charlotte, North Carolina
for analyses. The groundwater samples were analyzed for volatile organic compounds (VOCs) via
EPA Method 6200B including methyl tertiary-butyl ether (MTBE) and isopropyl ether (IPE). Select
natural attenuation measurements are provided in Table 2.

The laboratory analytical results from the April 2022 groundwater sampling event detected dissolved
total xylenes and naphthalene concentrations above their established 2L Standards in the
groundwater sample collected from monitoring well MW-6. Dissolved target compound
concentrations were not detected above established 2L Standards in the groundwater sample
collected from monitoring well MW-11. A summary of the recent groundwater analytical data is
presented in Table 3. A copy of the laboratory analytical report is included as Appendix A.

Groundwater Sampling – Water Supply Well
On April 8, 2022, a groundwater sample was collected from an irrigation water supply well
located at 106 Wintergreen Road (owned by the Wells family). Mr. Wells has previously stated
there are two irrigation wells used on the property. One irrigation well (closest to the source area)
does not have an access to sample the groundwater. A second irrigation well is located adjacent
to the main residence and provides water to a bib spigot (the location where ATC obtains a
groundwater sample). Prior to sample collection, the water was allowed to run for approximately
10 minutes. The water sample was collected into laboratory-approved containers, packed in ice
April27,2022
Page 2 of 2
and delivered under chain-of-custody to Waypoint for analyses. The groundwater sample was analyzed for volatile
organic compounds (VOCs) by Method 62008.
Laboratory analytical results of the groundwater sample collected from 106 Wintergreen Road detected dissolved
target compound concentrations (benzene, toluene, and ethylbenzene) above laboratory method detection limits but
below established 2L Standards. The NCDEQ incident manager was notified of these results via email on April 26,
2022. Cwrent supply well analytical results are provided in Table 3. A copy of the laboratory analytical reporl is
included as Appendix A.
-o-
ATC recommends continued annual groundwater sampling of wells MW-6, MW-ll, and the irrigation well at 106
Wintergreen Road. The next groundwater sampling event will be scheduled for April2023.
If you have any questions or require additional information, please contact our office at [phone].

Dear Maureen Jackson:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/12/2022 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely,
Angela D Overcash Senior Project Manager
