J. H. KLFINFELDER & ASSOCIATES <br /> luring the second .quarter of 1987, 14 soil borings, idenLified as B-6 <br /> through B-19, were completed at variablc depths above the uppermost <br /> water-bearing unit (refer to Figure 2). <br /> information collected from these <br /> borings has been used to assess the distribution of hydrocarbon compounds <br /> within the vadose zone, and to characterize the geology of the vadose zone <br /> underlying the site (refer to Table 2, Appendix A, and Appendix E). <br /> Three monitoring wells, identified as MW-4, MW-5, and MW-6, were installed <br /> during the second quarter of 1987 (refer to Figure 2)_ Information <br /> ccllected from these wells has been used to assess the. distribution of <br /> hydrocarbon compounds within the ground water (refer to Table 3, Appendix <br /> A, and Appendix E), characterize the site geology, and to meastue <br /> hydraulic characteristics of the ground water. <br /> A well, identified as RW-1, was installed during the second quarter of <br /> 198; (refer to Figure 2)• The objective of this well was to provide <br /> additional geolog!-a1 information, provide access for conducting a pumping <br /> test of the uppermost water-bearing unit and to initiate recovery of <br /> r <br /> contaminated ground water from the uppermost water-hearing unit. <br /> Soil boring lithology logs, rioni.toring well lithology logs, monitoring <br /> well construction details, and down-holt electrical logs are included <br /> within Appendix A. All available chemical analyses for soils and ground <br /> water are included within Appendix E. A soil chemistry summary is <br /> included within Appendix A (Table 2). A ground water chemistry summary is <br /> included within Appendix A (Table 3). <br /> i <br /> 5 <br /> 53-87-443 <br /> D <br />
