would be installed in the borehole. Based on agreements reached during the April 1 <br />meeting meeting, only two shallow borings (SB-1 and SB-2) were drilled at the <br />' <br />locations shown on Drawing 1. Only one discrete soil sample was collected for <br />chemical analysis from each boring during drilling. SB-1 encountered perched ground <br />' <br />water, and a monitoring well was installed in the borehole. No ground water was <br />encountered in SB-2. As shown on Drawing 4, SB-1 functions as the shallow <br />Iupgradient <br />well. <br />' <br />4.1.5 Sampling and Analysis Procedures <br />The analytical parameters included in the SWAT program were those specified in the <br />' <br />SWAT guidance manual. The parameters analyzed and the analytical methods used are <br />listed in Table 2. <br />Sampling methods, including sample preservation, shipment, and chain-of-custody <br />' <br />procedures, were in accordance with those presented in the EMCON February 1988 <br />SWAT proposal amended by RWQCB comments. Sampling methods are presented in <br />Appendix C. The ground-water monitoring wells were sampled on May 16 and 17, <br />' <br />1988. <br />' <br />4.2 ANALYTICAL RESULTS <br />' <br />The analytical results for samples collected for the SWAT program for organics, metals, <br />and conventional water quality parameters are presented in Tables 3 through 7. <br />' <br />Certified Analytical Reports are presented in Appendix D. <br />' <br />4.2.1 Quality Control Results <br />As part of EMCON's evaluation of the SWAT chemical data, the analytical results were <br />' <br />assessed based on quality control (QC) considerations. The QC program included both <br />field and laboratory procedures. <br />The field QC included field blanks, trip blanks, and field duplicates for the water <br />' <br />samples. One field blank and one trip blank, made with organic-free water, were <br />STL 9390314 18 Won O n Os /3q <br />
