Field quality control samples collected were trip blank; matrix spike/matrix spike duplicates (MS/MSD); and field duplicates. No ambient blanks were collected for this project. During the initiation of this project, it was determined that ambient blanks were not necessary due to the absence of a source at the site. The trip blank was analyzed for volatile organics only. All other field quality control samples were analyzed for the same parameters as their associated samples.
All samples were collected by Parsons. All analyses were performed by APPL, Inc. following procedures outlined in the AFCEE QAPP, version 3.0.
The data submitted by the laboratory has been reviewed and verified 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.
This SDG consisted of sixteen (16) samples, including twelve (12) confirmation environmental soil samples, one field duplicate soil sample, one set of matrix spike/matrix spike duplicate samples and one trip blank sample. The samples were collected on March 7, 2000 and analyzed for volatile organic compounds (VOCs).
VOC analyses were performed using United States Environmental Protection Agency (USEPA) SW846 Method 8260B. All samples for this SDG were analyzed following the procedures outlined in the AFCEE QAPP. All samples collected were prepared and analyzed within the holding times required by the method.
Accuracy was evaluated using the %R results for the MS/MSD samples; LCS samples; and surrogate spikes. Sample B15/16-SB05 (0.5-1.0�) was used as the MS/MSD sample in this SDG.
