Attn: Mr. Scott Ryals, P.E. RE: LETTER REPORT – LIMITED GROUNDWATER SAMPLING EVENT
W.T. Barlowe
297 North Chester Street Gastonia, Gaston County, North Carolina Groundwater Incident Number: 8172 UST Number: MO-3240 WR Project Number: 23-0307-EV
Mr. Ryals: WithersRavenel, Inc. (WR) has completed this Letter Report to document the limited groundwater sampling event at the W.T. Barlowe site, located at 297 North Chester Street in Gastonia,
Gaston County, North Carolina. Activities outlined herein were completed under North Carolina Department of Environmental Quality (NCDEQ) Contract # N70522-C, Task Authorization (TA) TA-01 for the above referenced site, approved by the Federal & State Lead Program on June 30, 2023. WR mobilized to the subject site on July 11, 2023, for the purposes of sampling monitoring wells MW-1 and MW-2. The General Location Map is included as Figure 1 and a site
map is depicted on Figure 2. Groundwater Sampling
On July 11, 2023, WR mobilized to the site to sample monitoring wells MW-1 and MW-2. Depth to water ranged from 12.35 feet below top-of-casing (TOC) in MW-2 to 15.75 feet below TOC in MW-1. After measuring depth-to-water within each well slated for sampling, each
monitoring well was purged and sampled using new, dedicated, disposable, polyethylene bailers.
Following purging, groundwater samples from each monitoring well were decanted directly from the bailers into pre-preserved, laboratory-grade sample containers. Following collection,
samples were placed into an ice-chilled cooler followed by transport under proper chain-of-
custody to Waypoint Analytical, Inc. (Waypoint) where they were analyzed for VOCs by SM 6200B.

Letter Report

August 2023
2
Laboratory analysis of the groundwater sample collected from monitoring well MW-2 indicated the presence of benzene, 1,2-dibromoethane, and 1,2-dichloroethane above the Gross Contaminant Levels (GCLs). Several other petroleum compounds were present in monitoring
well MW-2 in excess of the North Carolina Groundwater Quality Standards (2L Standards) and
ten times the North Carolina Surface Water Quality Standards (2B Standards). Laboratory analysis of the groundwater sample collected from monitoring well MW-1 indicated the presence of several petroleum compounds above the 2L Standards and ten times the 2B Standards. Analytical results for these samples are summarized in Table B-4. Groundwater
elevations are provided in Table B-9. Field notes, site photographs, and the laboratory analytical
report are included in the Attachments. WR appreciates the opportunity to be of service to the Federal & State Lead Program. Should you have any questions regarding the attached, please do not hesitate to contact us at (919)

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 7/11/2023 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
