Dear Kevin Buchanan:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 5/25/2023 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

Client: Withers & Ravenel CASE NARRATIVE
Project: St. Delight Baptist Church Lab Report Number: 23-145-0024
Date: 5/30/2023
Volatile Organic Compounds - GC/MS Method 6200B Analyte: 1,1-Dichloroethene QC Batch No: V33742/V33741
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-Hexanone QC Batch No: V33744/V33741
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: 4-Methyl-2-pentanone QC Batch No: V33744/V33741
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: Acetone QC Batch No: V33744/V33741
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: 1,2-Dibromo-3-chloropropane QC Batch No: V33744/V33741 Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
Analyte: Ethanol QC Batch No: V33744/V33741
Relative Percent Difference (RPD) for the duplicate analysis was outside of the allowable QC limits.
