Re: 4th Quarter 2023 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 September 28, 2023,
correspondence from NCDEQ.

On December 21, 2023, GRI personnel sampled 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 sample was collected from the spigot on the front of the
residence.
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 All contaminant concentrations were below the MACs. A concentration of chloroform
that did not exceed the MAC was reported in the WSW-Little sample.

 Lineberger Water Supply Well
o The Lineberger water supply well is now back in service. The Lineberger water supply well
sample was collected from the spigot on the back of the residence.

o The sample collected from the Lineberger 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 All contaminant concentrations were below the MACs. A concentration of chloroform
that did not exceed the MAC was reported in the WSW-Lineberger sample.

A trip blank was also submitted for analysis of VOCs by EPA Method 6200B. No detectable concentrations
of requested method constituents that exceeded the MACs were reported in the trip blank.

A Topographic Map showing the general site location and the surrounding area is included as Figure 1. A
Site Map showing the site and well locations is included as Figure 2. A copy of the laboratory analytical
report is included as Appendix A.

GRI recommends contacting the current property owners of the Little and Lineberger water supply wells
to determine if they would be agreeable to connecting to the available municipal water source and
abandoning their water supply wells.

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

Sincerely,

W. Scott Ball
Senior Project Manager

Dear Scott Ball:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/21/2023 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

Volatile Organic Compounds - GC/MS Method 6200B Analyte: 2-Butanone QC Batch No: V41839/V41775
CCV recovers low for this compound. All other QC passes within method parameters. All hits below MQL. No further action taken.
Analyte: Acetone
QC Batch No: V41839/V41775 CCV recovers low for this compound. All other QC passes within method parameters. All hits below MQL. No
further action taken.
Analyte: Vinyl acetate QC Batch No: V41839/V41775
This target analyte was flagged for recoveries outside QC limits in the associated LCS/LCSD. Data for this analyte is flagged "M" to indicate that results should be considered minimum concentration due to the potential for
a low bias. LCS/LCSD fails low. A standard at or below the MQL was run and saw recovery.
