None of the analytes were detected at or above MRLs in any of the samples <br /> (Tables 6 and 7). <br /> Three equipment blanks (QCEB-1, QCEB-2, and QCEB-3) were collected during first quarter <br /> monitoring and sampling activities. None of the analytes, with the exception of methanol, were <br /> detected at or above MRLs in any of the equipment blanks (Tables 6 and 7). Methanol was <br /> detected in one of the equipment blanks at a concentration of 56 pg/L, well below the WQO for <br /> methanol. <br /> Duplicate samples were collected from "A" zone well PS/MW-20A (labeled QCDup-1), "B" zone <br /> well AR/MW-8B (labeled QCDup-2), and "D" zone well TS/MW-2D (labeled QCDup-3) (Tables 6 <br /> and 7). <br /> Analytical Results <br /> Certified laboratory analytical reports, chain-of-custody documentation, and field data sheets for <br /> first quarter 2010 are included in this Appendix. <br /> The summary tables on the following pages provide a concise overview of groundwater quality <br /> and cleanup progress by comparing results with WQOs and also presents average and median <br />
