221 Sav-A-Stop
4613 US Highway 221 North Marion, McDowell County, North Carolina Groundwater Incident Number: 10748 UST # AS-966
NCDEQ Contract # N70522-C
WR Project Number: 23-0307-G Dear Ms. Ghiold:
WithersRavenel, Inc. (WR) has prepared this letter report documenting the performance of
assessment activities at the subject site in association with task authorization (TA) TA-01 under North Carolina Department of Environmental Quality (NCDEQ) Contract # N70522-C, authorized by NCDEQ on February 28, 2023. WR personnel mobilized to the site on March 8, 2023 for the purposes of completing assessment activities associated with this TA. A site map is included as Figure 1.
Groundwater Sampling WR was tasked with collecting groundwater samples from monitoring wells MW-15 and EM-3, which included the gauging, purging and sampling of the wells and submittal of groundwater
samples for analysis by SM6200B. Prior to the sampling, WR personnel gauged MW-15 and EM-
3 with a decontaminated electronic water level indicator and determined the depth to groundwater within the wells. The depth to groundwater measurements were 5.93 feet below the top of casing (ft-BTOC) in monitoring well MW-15 and 5.96 ft-BTOC in monitoring well EM-3. Following gauging, the monitoring wells were purged and sampled using separate, disposable
polyethylene bailers.
Samples collected from monitoring wells MW-15 and EM-3 were contained in pre-preserved, laboratory grade bottles provided by Waypoint Analytical (Waypoint). The samples were submitted to Waypoint under chain of custody (COC) protocols for analysis of volatile organic
compounds (VOCs) by SM6200B. Field notes and site photos for the March 8, 2023 sampling
event are included as Attachment A.

Supply Well Sampling WR also obtained a sample from the on-site water supply well, WSW. This sample was obtained by WR personnel following a 15-minute purge of the well. Samples were collected in pre-
preserved laboratory-grade sample containers supplied by Waypoint. Samples were relinquished
to Waypoint under chain of custody protocols for analysis by SM6200B with the extended compound list requested. Laboratory Results
Laboratory results for the groundwater samples obtained from monitoring wells MW-15 and EM-
3 and water supply well WSW on March 8, 2023 did not indicate the presence of targeted compounds at concentrations exceeding the laboratory method detection limits (MDLs). Data associated with the samples are also included in abbreviated Table B-4 (attached). The laboratory report for the samples is included as Attachment B.

Conclusions No compounds were reported at concentrations above North Carolina Groundwater Quality Standards (NC 2L Standards), North Carolina Surface Water Standards (NC 2B Standards), or Gross Contamination Levels (GCLs).

WR will sample MW-15, EM-3, and water supply well WSW in June 2023. Should you have any questions or comments regarding the content of this letter report, please contact us at [phone].

Cordially,

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/10/2023 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
