Dear Seth C. Rickerts:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/25/2024 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

in the method blank.
Sample 91794 (LL-2) Analyte: Vanadium

Analyte: Vanadium QC Batch No: L748679/L748350
Target analyte(s) was identified in the method blank associated with this project, below the Method Quantitation Limit. Per laboratory protocol any associated affected sample result is flagged "B" to indicate that it was detected
in the method blank. Volatile Organic Compounds - GC/MS Method 8260B Sample 91794 (LL-2)
QC Batch No: L748675/L748519 Surrogate recovery(s) was flagged as outside QC limits due to high levels of target and/or non-target analytes.
Batch QC samples (method blank and laboratory control samples) all showed surrogates within QC limits. Sample 91795 (SW-1) Analyte: Dibromofluoromethane QC Batch No: L748675/L748519 Surrogate(s) exhibited a high bias in this project sample where no target analytes were detected. The high
recovery(s) had no impact on the data. Batch QC samples (method blank and laboratory control samples) all showed surrogates within QC limits.
