Data Verifiers: Michelle Wolfe & Tammy Chang
The following data verification summary report covers environmental soil samples and associated field quality control (QC) samples collected from the Camp Stanley CSSA Site (under RL53) during the period February 28, 2000. The samples in the following laboratory Sample Delivery Group (SDG) were analyzed for volatile organic compounds (VOCs) and metals which includes barium, chromium, copper, nickel, zinc, mercury, arsenic, cadmium and lead:
Field quality control samples collected were trip blank and field duplicate. Parsons ES did not collect any ambient samples for VOC analysis due to the lack of determined source from the site. The trip blank was analyzed for volatile organics only. The field duplicate sample was analyzed for the same parameters as its parent sample.
All samples were collected by Parsons Engineering Science (Parsons ES). 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 eleven (11) samples, including nine (9) confirmation environmental soil samples, one field duplicate soil sample and one trip blank sample. The samples were collected on February 28, 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 normally evaluated using the %R results for the MS/MSD samples; LCS samples; and surrogate spikes. There was no MS/MSD analysis requested by Parsons ES in this SDG.
All LCS %Rs for soil and water were within acceptance criteria. The surrogate %Rs were within acceptance criteria.
Precision was normally evaluated using the Relative Percent Difference (RPD) results obtained from MS/MSD results; and the field duplicate analyte values. There was no MS/MSD analysis requested by Parsons ES in this SDG. Sample B11-SB03 (10.0�) FD was the field duplicate of sample B11-SB03 (10.0�).
All field duplicate RPDs were within acceptance criteria.
Completeness has been evaluated by comparing the total number of samples collected with the total number of samples with valid analytical data.
All results were considered usable. The completeness for this SDG is 100.0% compared to the minimum acceptance limit of 90%.
Representativeness expresses the degree to which sample data accurately and precisely represents actual site conditions. Representativeness has been evaluated by:
