||This report presents the results of EPA's interlaboratory validation of EPA Method 1668A Chlorinated Biphenyl Congeners in Water, Soil, Sediment, and Tissue by HRGC/HRMS. This study was conducted in 2003-2004 to validate the performance of EPA Method 1668A in municipal wastewater, fish tissue, and biosolids matrices. EPA used the results of the study to evaluate and revise Method 1668A quality control (QC) acceptance criteria for initial precision and recovery, ongoing precision and recovery, and labeled compound recovery from real world samples. These interlaboratory criteria (Table 5-1) replace the single-laboratory criteria, and are published in Table 6 of the revised version of this PCB-congener method, EPA Method 1668B.
