Field quality control samples collected was trip blank. The trip blank was analyzed for volatile organics only. Parsons ES did not collect any ambient samples for VOC analysis due to the lack of determined source from the site. All samples were collected by Parsons Engineering Science (Parsons ES). All analyses were performed by APPL Laboratories, Inc. following procedures outlined in the AFCEE QAPP, version 3.0.

Evaluation Criteria

The data submitted by the laboratory has been reviewed and validated following the guidelines outlined in the AFCEE QAPP, version 3.0. Information reviewed in the data packages include sample results; the summary of laboratory quality control results; case narrative; raw data; and chain-of-custody forms. The analyses and findings presented in this report are based on the reviewed information, and whether guidelines in the AFCEE QAPP were met.
