( ' 3.0 SCOPE OF WORK <br /> In order to evaluate potential impacts to subsurface soil and ground water on the subject <br /> L.r <br /> property resulting from former site activities, a field program consisting of borehole drilling <br /> I <br /> and soil and ground water sampling will be conducted. Three soil borings will be drilled on <br /> the Property to the top of the water-bearing zone (estimated at a depth of 45 feet below <br /> Lground surface [bgs]). Upon encountering the water-bearing zone, an attempt will then be <br /> made to collect a ground water sample from each of the borings using a Hydropunch' <br /> sampling device. Soil samples will be collected at approximately 5-foot intervals, beginning <br /> at the surface and extending to the total depth of the borehole. The proposed soil <br /> boring/Hydropunch' locations are shown on Figure 2. The proposed placement of soil <br /> borings is based on the review of the Sanborn maps (1921 and 1941) and the former <br /> locations of the tire vulcanization facility and the gas station. Selected soil and ground water �7 <br /> samples will be analyzed for total petroleum hydrocarbons as diesel (TPH-D); benzene, <br /> toluene, ethylbenzene, and xylenes (BTEX); phenols; and California Assessment Manual <br /> I <br /> (CAM) metals. <br /> II <br /> The following sections detail the planned site investigation procedures and present the <br /> anticipated schedule for fieldwork and reporting. <br /> i <br /> Lr <br /> L <br /> 809-001.wkp/03-O6r97/u/keydata/workplan 5 <br /> f TerraNeXt <br />
