Kennedy/Jenks Consultants <br /> Ell, <br /> was placed in a polyethylene Ziploc®bag, the bag was sealed, and then the soil was <br /> broken up and agitated. The bag was allowed to stand for approximately 10 minutes, <br /> agitated again, and then the PID probe was inserted into the bag. The PID reading for <br /> each sample was recorded and noted on each boring log opposite the respective sample <br /> interval (Appendix B). <br /> Reconnaissanceroundwater samples - - <br /> g mpl s were collected from Soil Borings KB 1, KB 2, and <br /> K13-4. As described above, Precision was unable to advance Soil Boring KB-3 deep <br /> enough to intersect the water table. Groundwater sampling methodology was completed <br /> as described in the Work Plan (Kennedy/Jenks, 1995). - Upon completion of sampling, each <br /> borehole was sealed with cement/bentonite grout. <br /> Drill cuttings were stored in two, metal 5-gallon pails. Water from steam-cleaning activities <br /> was stored in a DOT-approved 55-gallon drum with a locking rim. The pails and drum were <br /> labeled for identification purposes and left onsite for proper disposal by Stockton Savings <br /> Bank pending analytical results. <br /> 2.3 Lithology <br /> The Lithology of the Site consists primarily of sand, sift and clay. In general, lean clay is- <br /> present in the upper 12 to 13 feet of the Site. This clay is underlain by silt and silty sand to <br /> L� a depth of approximately 18.5 to 18.5 feet bgs. Underlying the silt and silty sand in Soil <br /> Borings KB-1 and KB-2 is a poorly-graded sand unit, which was observed at depths of <br /> approximately 17 and 18.5 feet bgs, respectively. The sand unit was not observed in Soil <br /> Boring KB-4. Groundwater was encountered during drilling at depths between <br /> approximately 17 and 19 feet bgs. <br /> l <br /> I <br />' 1:5 ob19W50073.001rosubsurAtektdoc 4 <br />
