Sincerely, re- 5__ . _5 Ted Soyars Technical Director End Notes: The test results listed in this report relate only to the samples submitted to the laboratory and as received by the Laboratory. Unless otherwise noted, the test results for solid materials are calculated on a wet weight basis. Analyses for pH, dissolved oxygen, temperature, residual chlorine and sulfite that are performed in the laboratory do not meet NELAC requirements due to extremely short holding times. These analyses should be performed in the field. The results of field analyses performed by the Sampler included in the Certificate of Analysis are done so at the client's request and are not included in the laboratory's fields of certification nor have they been audited for adherence to a reference method or procedure. The signature on the final report certifies that these results conform to all applicable NELAC standards unless otherwise specified. For a complete list of the Laboratory's NELAC certified parameters please contact customer service.

Dilution Factor. Please also see the Preparation Factor in the Analysis Summary section. TIC Tentatively Identified Compounds are compounds that are identified by comparing the analyte mass spectral pattern with the NIST spectral library. A TIC spectral match is reported when the pattern is at least 75% consistent with the published pattern. Compound concentrations are estimated and are calculated using an internal standard response factor of 1. PCBs, Total Total PCBs are defined as the sum of detected Aroclors 1016, 1221, 1232, 1248, 1254, 1260, 1262, and 1268.

FedEx Express Were Custody Seals used? If so, were they received intact? No Are the custody papers filled out completely and correctly? No Do all bottle labels agree with custody papers? Yes Is the temperature blank or representative sample within acceptable limits or received on ice, and recently taken? Yes Are all samples within holding time for requested laboratory tests? Yes Is a sufficient amount of sample provided to perform the tests included? Yes Are all samples in appropriate containers for the analyses requested? Yes Were volatile organic containers received? No Are all volatile organic and TOX containers free of headspace? NA Is a trip blank provided for each VOC sample set? VOC sample sets include EPA8011 , EPA504, EPA8260, EPA624, NA EPA8015 GRO, EPA8021, EPA524, and RSK-175. Are all samples received appropriately preserved? Note that metals containers do not require field preservation but lab Yes preservation may delay analysis. *Logged per analyses specified by Matthew Henry via phone and email, which differ from COC. *Logged with collection date of 01/04/23, which differs from COC (01/04/22), per Matthew Henry via email.
