� CAMBRIA <br /> borings MW-10 and MW-11 are recorded on the boring logs <br /> (Appendix C) <br /> Groundwater Sampling Groundwater samples were collected in borings SB-5 and SB-6 <br /> using Hydropunch equipment at ten-foot intervals or at depths <br /> where CPT logs indicated the presence water-bearing soils for <br /> chemical analyses <br /> Number of Borings Two CPT borings (SB-5 and SB-6) and two well borings <br /> (MW-10 and MW-11) Boring specifications are described to <br /> Table I and Iocations are shown on Figure 2 <br /> Boring Depths Boring SB-5 was advanced to 100 06 fbg The CPT log for <br /> boring SB-6 encountered refusal at 80 54 fbg, but subsequent <br /> SB-6 soil and groundwater sampling borings were advanced to <br /> 100 fbg Well borings MW-10 and MW-11 were drilled to <br /> 45 fbg <br /> • Groundwater Depths During drilling activities, ressure ore dissipation test <br /> F p p s to <br /> borings SB-5 and SB-6 indicated groundwater depths in the <br /> borings at approximately 31 and 33 fbg, respectively During <br /> drilling activities,groundwater was first encountered at 38 fbg in <br /> MW-10 and at 36 fbg in MW-11 Blaine Tech Services, Inc <br /> (Blaine) of San Jose, California measured groundwater in wells <br /> MW-1 through MW-7, MW-10, MW-11, and VEW-1 at depths <br /> ranging from 32 45 to 34 35 fbg on December 10, 2001 <br /> Blaine's well gauging data is included in Appendix D <br /> Sediment Lithology Lithology encountered while drilling the borings consisted of <br /> varying intervals silt (ML), sand (SP) and silty sand (SM) to the <br /> total explored depth of 100 fbg (Appendices B and C) <br /> Coil Chemical Analyses Selected soil samples wet e andlyzed for TPHg, benzene, <br /> toluene, ethylbenzene, xylenes (BTEX), and MTBE by EPA <br /> Method 8015MJ8020 or 8260B) <br /> 0854 4 <br />
