i <br /> The borings which are to be completed as monitor wells will be drilled to <br /> a depth of approximately 20 feet. The monitor. wells will be constructed <br /> through the hollow stem auger using 2-inch diameter flush threaded <br /> Schedule 40 PVC casing and 17-feet of 0.021-inch slotted PVC screen. <br /> Figure 4 shows the proposed monitor well design for the Stockton Ford New <br /> Holland site. The actual well design will b,�e based upon site specific <br /> conditions encountered during drilling. <br /> The monitor wells will be developed and sampled following construction. <br /> Prior to sampling, the well heads will be surveyed and the groundwater <br /> static levels measured to determine the local' direction and gradient of <br /> groundwater flow. Groundwater samples will 'Ibe analyzed for TPH using <br /> modified EPA Method 8015 and BTXE by EPA Method 602. In addition, a <br /> LL groundwater sample from the monitor well immediately adjacent to the <br /> excavation will be analyzed for tetraethyl load (TEL) and for ethylene <br /> dibromide (EDB) . <br /> , <br /> Following completion of the site assessment work a Site Assessment Report <br /> will be prepared pursuant to SJLHD guidelines. The report will <br /> C incorporate information presented in thisPreliminary Report, will <br /> document field activities, and will present an evaluation of the <br /> analytical results. The extent of soil and groundwater contamination will <br /> be identified and remedial actions for site cleanup will be proposed, if <br /> necessary. <br /> i <br /> it <br /> l <br /> i <br /> i <br /> I: <br /> Lr <br /> J <br /> ' l <br />
