SCOPE OF WORK <br /> The objective of the Limited Phase II ESA was to evaluate potential impacts to <br /> subsurface soil and groundwater beneath the Site as a result of past Site land use based <br /> on the RECs listed above. The scope of work included: <br /> • Soil sampling at soil boring locations GSB-1 through GSB-4: Soil sampling <br /> was conducted to evaluate the soil conditions at the Site for the presence of <br /> pesticides and herbicides. Spent lime was mixed with native soil and"tare" soil <br /> (soil generated during beet washing) before being redistributed in the vicinity of <br /> the sugar plant. The Site was included in the area that was graded and filled <br /> with the lime soil mixture in 1999. At least one soil sample was collected from <br /> fill material at each location as shown on Figure 2. <br /> • Groundwater Sample Collection: Groundwater typically flows to the north- <br /> northwest. Locations GSB-1 and GSB-2 were located on the downgradient edge <br /> of the Site and provided data for groundwater flowing away from the Site. <br /> GSB-3 was located on the upgradient edge of the Site and provided data for <br /> groundwater flowing into the Site. One groundwater sample was collected from <br /> each boring at GSB-1 through GSB-3. <br /> 3.1 Methodology <br /> Prior to the start of field activities, Underground Services Alert(USA) was notified and <br /> utilities were cleared by a private utility locator. A soil boring permit was obtained <br /> from the San Joaquin County Environmental Health Department(SJCEHD). As part of <br /> the SJCEHD permit process, access to the property was obtained from the current <br /> property owner,Prologis, Inc. <br /> Investigation activities were conducted on 21 November 2013 using a direct push rig to <br /> collect soil and groundwater samples. Upon completion of soil and groundwater <br /> sampling activities, all direct-push boreholes were backfilled to ground surface with <br /> neat cement grout. A brief description of the field sampling program is presented in the <br /> following sections. <br /> 3.1.1 Soil Sampling <br /> A total of four soil borings (GSB-1 through GSB-4) were advanced as part of this <br /> Limited Phase 11 ESA (Figure 2). The upper 5 feet of each boring was advanced using a <br /> Phase II ESA-1351 Dupont_FINAL_12302013 3 1/2/14 <br />
