I <br /> i <br /> iE <br /> i <br /> i <br /> 3.0 SCOPE OF WORK r ' <br /> In order to evaluate potential impacts to subsurface soil and4 ground water at the site resulting <br /> from past and present activities at or in the vicinity of the Site, a Fifield program consisting of <br /> borehole drilling and soil and ground water sampling will be conducted. Nineteen soil <br /> borings will be drilled on the Site to the top of the water-bearing p one (estimated at a depth <br /> I ` <br /> of 20 feet below ground surface [bgs]). Upon encountering the water-bearing zone, an <br /> I <br /> attempt will be made to collect a ground water sample from each!of the borings using a <br /> Hydropunch' sampling device. Soil samples will be collected at approximately 5-foot <br /> intervals, beginning at the surface and extending to the total dept� of the borehole. The <br /> proposed soil boring/Hydropunch' locations are shown on Figure2. The proposed <br /> 1 <br /> placement of soil borings is based on the location of the USTs identified to the east of <br /> Parcel 4, and the activities/conditions identified in Section 2.0, involving properties located <br /> I l <br /> in the vicinity of the Site. Selected soil and ground water samples will be analyzed for total � <br /> f petroleum hydrocarbons as diesel (TPH-D); TPH as gasoline (TP H-G); benzene, toluene, <br /> ethylbenzene, and xylenes (BTEX); and California Assessment Manual (CAM) metals. <br /> !F ` <br /> ,I <br /> The following sections detail the planned site investigation procedures and present the <br /> anticipated schedule for fieldwork and reporting. <br /> 'k <br /> II I i' <br /> I � <br /> f <br /> i I l <br /> I k <br /> j� 11 <br /> II f <br /> I i � <br /> I i <br /> k I <br />' 808-001.wkpI03-14-971ulkeydata/workp1an 7 <br /> I <br /> ,I I <br /> C <br />
