• • <br /> Each soil sample will be field screened with a Photoionization Detection (PID) meter or similar <br /> instrument. The samples collected at three feet bgs from each of the four borings and one 16 to 1 <br /> composite sample consisting of the remaining soil samples (those collected every 5 feet) in each <br /> boring, will be placed in a cooler with ice and submitted for laboratory analysis. Following soil <br /> sample collection, the borings will be backfilled with cement grout to the surface. <br /> All drill cuttings, if any, will be stored on-site in a 5-gallon container pending laboratory results. <br /> If laboratory results indicate that analytes are below detection limits in the soil samples from the <br /> borings, then Smith Technology personnel will spread the cuttings on the site. If necessary, based <br /> on analytical results, soil disposal or treatment options will be evaluated. <br /> Soil Sample Analysis <br /> The selected soil samples will be transported, using chain-of-custody record, to a State-certified <br /> laboratory for analysis. Samples from the four borings, five samples total, will be analyzed for: <br /> priority pollutant metals (Sb, As, Be, Cd, Cr, Cu, Pb, Hg, Ni, Se, Ag, TI, and Zn) by EPA 6010A; <br /> fuel fingerprinting (hydrocarbon screen) by EPA 8015M; benzene, toluene, ethylbenzene, xylenes <br /> (BTE3), total petroleum hydrocarbons as gasoline (TPHg) and diesel (TPHd) by EPA methods <br /> 602/8020/8015; and pesticides by EPA method 8080. <br /> Report Preparation <br /> Smith Technology will prepare a report for submittal to San Joaquin County Public Health <br /> Services, Environmental Health Division (PHS/EHD) which will include a description of all field <br /> activities, laboratory analytical results, boring logs, and recommendations, if any. A copy of the <br /> report will also be sent to DPW. <br /> All work described in this proposal will be performed under the direct supervision of a California <br /> Registered Professional Engineer. All field work will be completed in accordance with the field <br /> procedures contained in Attachment I and the Site Safety Plan contained in Attachment 2. A soil <br /> boring permit application is contained in Attachment 3 with a check for the permit fee. Also <br /> enclosed as Attachment 3, please find a completed Master File Record Form, completed by <br /> George Chen of the DPW and the associated fee of$234. <br /> w:197715Veports\ssiwkp.dm 2 <br /> SION <br />
