• <br />1.5 Laboratory Quality Assurance/Quality Control <br />All of the laboratory analyses will be conducted using EPA-approved analytical methods specified in <br />either EPA (1983) or EPA (1986). Routine laboratory QA/QC procedures will be used for the analyses. <br />The QC measures will include laboratory blanks, duplicate analyses of A Pit samples, and laboratory <br />control standards. laboratory blanks are used to determine potential laboratory cross~ontamination. The <br />duplicate analyses are used to determine the reproducibility of the resuks. Laboratory control standards <br />are used to determine the accuracy of the resuhs. Matrix spike analyses are used to determine the sample <br />matrix characteristics and percent recovery. <br />
