Site-specific quality control (QC) issues are discussed here in terms of precision, accuracy, representation, comparability, and completeness. Data, including data validation flags, are presented in Table C.1. Table C.2 contains explanatory information for Table C.1. QC data are presented beginning with Table C.3. C.1 PRECISION Precision is controlled through the use of field duplicates and matrix spike duplicates. C.1.1 Field Duplicates In accordance with Section A.3.5 of the QAPP (Appendix A of Parsons, 2010), field duplicates are required at a rate of one per 20 samples of the same matrix. Field duplicate frequency was measured program-wide and not per individual site. Thirty-two soil samples were collected at this site during the RFI. One field duplicate was collected associated with these samples. However, a total of 14 field duplicates were collected in association with 240 normal field samples collected program-wide at the inactive landfills and Muggins Mountain OB/OD sites. Therefore, overall field duplicate frequency was met for the RFI. Table C.3 presents the results of the field duplicate sample (141EP012) collected at this site. The field duplicate acceptance limit is defined as 35 Relative Percent Difference (RPD) for soil samples. If excessive exceedances of the RPD limit are identified, required action is to evaluate the sampling program to determine if field sampling protocols are being followed and implement corrective action if required. One hundred and fifty-nine distinct analytes were tested for in the one field duplicate, generating 168 duplicate pair results (the greater number of results comes from the same analytes being tested for in two methods). Soil test panels included: volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), explosives, and metals. The RPD is evaluated when C-1 Final RCRA Facility Investigation Report for YPG-141 U.S. Army Garrison Yuma Proving Ground Revision 0, March
