Analytical Testing Lab Report Number: 21-109-0004 Client Project Description: Allen Middle School Project Number: GCS-001. Dear Christine Schaefer: Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/19/2021 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 2012) 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 asreceived 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. Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.  .
