r <br /> 25 feet with a direction of now to the northwest. Local ground water characteristics could <br /> vary from these historical maps at the time of drilling. <br /> PROXIMITY TO WELLS AND UTILITIES <br /> Ground water resources within the Sar. Joaquin basin are intensively developed for <br /> irrigation, domestic, industrial, municipal and stock use. Numerous ground water supply <br /> wells are in the vicinity of the site. At least one municipal water supply well and one <br /> domestic supply well are located within 2,000 feet of the site. some of the wells noted are <br /> probably iriactive,a nd other wells may exist in the vicinity,but do not appear in the records. <br /> ic utilities near the site are depicted on Plate P <br /> The locations of known publ -2. Utility <br /> search o:the area indicate no septic tanks, leachfields, and underground public utility lines <br /> are located in the vicinity of the site. <br /> PROPOSED WORK <br /> This proposed investigation is designed to assess the presence of hydrocarbon <br /> eneath the site. The following tasks are proposed <br /> contamination in soil and ground water b <br /> and discussed in the following sections. <br /> G Acquire permits from the San Joaquin Local Health Department. <br /> o Prepare a Site Safety Plan. <br /> Drill three soil borings at the approximate locations shown on Plate P-1 to <br /> approximately 40 feet below grade or 2 to 5 feet below the bottom of the <br /> uppermost water bearing unit. Borings will be drilled using 8-10 inch outer <br /> diameter hollow stem augers. <br />
