Re: 4th Quarter 2022 Water Supply Well Sampling
Express Food Mart
6050 South NC Highway 16 Bus.
Denver, North Carolina
Catawba County
Incident Number: 3898
GRI Project Number: 2099

Dear Mr. Newton:

GRI presents the results of the water supply well water sampling activities at the Express Food Mart site
in Denver, North Carolina. The activities were conducted in response to the October 3, 2022
correspondence from the NCDEQ.

On January 10, 2023 GRI attempted to sample two water supply wells in the vicinity of the Express Food
Mart. The two water supply wells are located at the Little property and the Lineberger property. A
summary of field observations and analytical results for each property follows:

 Little Water Supply Well
o The Little water supply well had no electrical power. However, GRI personnel were able
to access the interior of the well and collect a water sample using a disposable Teflon
bailer.
o The sample collected from the Little water supply well was placed in laboratory supplied
bottles and placed in a cooler on ice. The samples were submitted to Waypoint Analytical
in Charlotte, North Carolina under standard chain-of-custody protocol for laboratory
analyses of volatile organic compounds (VOCs) by EPA Method 6200B and 1,2-
dibromoethane (EDB) by EPA Method 504.1.
o The concentrations of benzene, chloroform, and di-isopropyl ether (DIPE) reported in
WSW-Little were above the method detection limit (MDL), but below the MAC.
o A trip blank also was submitted for analysis of VOCs by EPA Method 6200B. No detectable
concentrations of requested method constituents were reported in the trip blank.

 Lineberger Water Supply Well
o The Lineberger water supply well had no electrical power; therefore, no sample could be
collected.
o The residential property containing the Lineberger water supply well appears to be
vacant.

A Site Location Map and Site Map have been included as Figures 1 and 2. A copy of the laboratory
analytical report is attached.

Please contact me at 704-845-4010 or [e-mail] with any questions or
comments.

Dear Scott Ball:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 1/11/2023 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,
Danyale Love Project Manager
