C A M B R I A i converted into piezometers Boring and well specifications are described in Table 1 and their locations are shown on Figure 2 Boring Depths• Borings MW4, MW-5, P-1, and P-2 were drilled to 63 feet below grade (fbg) and borings MW-6 and MW-7 were drilled to 60 and 65 fbg,respectively Groundwater Depths. During drilling activities, groundwater was observed in well borings MW-4 through MW-7, P-1, and P-2 at depths ranging from 49 to 55 fbg Blaine Tech Services, Inc (Blaine) of San Jose, California measured groundwater in all of the site wells at depths ranging from 50 98 to 52 37 fbg on September 19, 2002 Blaine's well gauging data is included in Appendix C Soil Types: Soil types encountered during drilling consisted predominantly of silty sand (SM), sandy silt (ML), and sand(SP) at varying depths and thicknesses to the total explored depth of 65 fbg Soil types from the borings are recorded on the boring logs (Appendix B) Chemical Analyses Selected soil and groundwater samples from the well borings were analyzed for TPHg, BTEX, and fuel oxygenates (MTBE, di-isopropyl ether, TAME, ETBE, and TBA) by EPA Method 8260B Additionally, selected soil samples collected from well boring MW4 were subrmtted for grain size analysis Soil Disposal: Approximately 12 cubic yards of soil were generated during field activities, stored onsite, and covered with plastic sheeting The soil stockpile was sampled and profiled for disposal (laboratory data in Appendix D) On October 1, 2002, Manley and Sons Trucking, Inc of Sacramento, California transported the soil to Allied Waste Industnes' Forward Landfill in Manteca, California for disposal Well Materials: Wells P-1 and P-2 were constructed using two-inch diameter Schedule 40 PVC casing, wells MW-5 through MW-7 were . constructed using four-inch diameter Schedule 40 PVC casing, and well MW-4 was constructed using six-inch diameter 0955 6
