i <br /> Each soil boring was terminated at a depth sufficient to collect a groundwater grab sample. The soil <br /> with neat cement sl after sampling was completed. <br /> borings were backfilled to the surface �T3' p <br /> Backfilling was completed under the supervision of San Joaquin County Public Health Services <br /> Inspector. The borings SHP-1 through SHP-5 adjacent to the existing wells MW-2, MW-3, MW-4, <br /> MW-6, and MW-7 were'not logged. The boring SHP-6, east of soil boring S133, was logged by a <br /> geologist in accordance with Unified Soil Classification System (USCS), under the supervision of a <br /> California Registered Geologist. The boring log is included in Appendix C. <br /> 3.3 Soil Sampling <br /> Soil boring SHP-6 located to the east of soil boring SB3 was cored continuously. Soil cores were <br /> obtained by pushing a Geoprobe Tm sampler with 4-foot long acrylic liners into the subsurface. Upon <br /> retrieval of the 4-foot long acrylic liner from the borehole, the samples were screened using a <br /> photoionization detector (PID). Based on the FID readings, a section of the liner was cut out at the <br /> g <br /> selected sampling depth <br /> of 12 feet h s for submittal to the analytical laboratory. The PID readings <br /> showed only low readings, therefore only one soil sample was collected. The ends of the acrylic tube <br /> containing the soil to be tested were covered with Teflon, capped with plastic end-caps, and placed in <br /> ziplock plastic bags. The soil sample was then labeled and transferred to a California Certified <br /> analytical laboratory using chain-of-custody protocol. <br /> I� <br /> I� <br /> '� 1;11n Pn.grcoo1!I KNTOP1O5 I12kREPOHTM21N!ItSuil%,H,n ­]%II ln•1ulWti..ndiw <br />
