Re: Proposal #23-773
Ground Water Sampling
Silver Express
5115 North Tryon Street
Charlotte, Mecklenburg County, North Carolina
Incident #48487
GRI Project #5413

Dear Mr. Bowser:

Geological Resources, Inc. (GRI) presents the results of the ground water sampling activities at the Silver
Express site in Charlotte, North Carolina.

On December 26, 2023, GRI gauged and sampled monitoring wells MW-1 through MW-4. No free
product was observed while sampling. Ground water samples were collected from all wells and
submitted for analyses of VOCs by EPA Method 6200B including oxygenates. Depths to water in the
wells ranged from 23.69 to 26.14 feet below tops-of-casings prior to sampling. A Site Location Map and
Site Map are included as Figures 1 and 2.

Please see the attached laboratory report for the results of the December 2023 ground water sampling.
The concentrations of VOCs in the ground water samples collected from MW-1 through MW-4 exceeded
the MACs. The concentration of EDB in the ground water sample collected from MW-1 exceeded the
GCL. A summary of ground water sample analytical results is presented in Table 1. A copy of the
laboratory report is included as Appendix A.

Please contact me at 888-870-4133 or [e-mail] with any questions or comments.

Sincerely,

Ashleigh Thrash, P.G.
Project Manager

Dear Ashleigh Thrash:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/29/2023 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

Project: Silver Express Lab Report Number: 23-363-0016
Date: 1/10/2024
Volatile Organic Compounds - GC/MS Method 6200B Analyte: 1,2,3-Trichlorobenzene QC Batch No: V42022/V42020
LCSD fails high. All other QC for this batch passes including the LCS. Data no affected.
Analyte: 1,2,3-Trichlorobenzene QC Batch No: V42078/V42020
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable.
Analyte: 2-Butanone QC Batch No: V42095/V42020
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable. All hits below MQL.
Analyte: Acetone
QC Batch No: V41956/V42020 CCV fails low. All other QC passes within method parameters. Data not affected. No further action taken. Analyte: Acetone
QC Batch No: V42095/V42020 Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the
batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be acceptable.
All hits below MQL. Analyte: 1,2-Dibromo-3-chloropropane QC Batch No: V41956/V42020
Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable. Analyte: 1,2-Dibromo-3-chloropropane QC Batch No: V42022/V42020 Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be
acceptable. Analyte: tert-Amyl alcohol QC Batch No: V41956/V42020 Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
