00-3737 <br /> At the request of PHS-EHD, Paragon placed all drill cuttings in separate, labeled 55- <br /> gallon drums. As of the date of this Report, these drums remain staged on the sidewalk <br /> area behind the Site building. In accordance with Cal EPA guidance, Spectrum developed <br /> the wells on August 2, 2000 by surging them with potable water, then pumping 20 gallons <br /> (16-21 well volumes) from each well. They disposed of purge water from each well into <br /> its respective boring's soil cuttings drum. <br /> Paragon collected groundwater samples from all six wells on August 3, 2000 in <br /> accordance with our standard protocols (see Appendix D). We did not observe any odors <br /> or oily sheen associated with these samples. <br /> Paragon submitted groundwater samples to Zymax for laboratory VOC analysis. Table 5 <br /> below summarizes the results of laboratory groundwater analyses. Appendix E presents <br /> Zymax certificates of analysis and chain of custody documentation. <br /> Table 5: Groundwater Analytical Results (NgIL) <br /> Parameter MW-1 MW-2 MW-3 MW-4 MW-5 MW-6 Standard <br /> cDCE BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) 6 <br /> OCE BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) BDL(0.5) 1 n <br /> TCE BDL 0.5 BDL 0.5 BDL QS BDL QS BDL 0.5 BDL 0.5 5 <br /> PCE 2.9 BDL(0.5) 3.5 BDL(0.5) 1.4 BDL(0.5) 5 <br /> Standard=California Department of Health Services Prima Maximum Contaminant Level(MCL)for drinking <br /> water, BDL =Below Detection Limit(limit in parentheses <br /> The only compound Zymax identified in Site groundwater samples above method <br /> detection limits is PCE in the samples from PES-1, PES-3, and PES-5.
