y <br /> CAMBRIA <br /> Permits• Permits numbered 36733 and 36734 were obtained from <br /> SJCEHD (Appendix A) and an access agreement was secured <br /> between Shell and the property owner of the step mall across <br /> Pacific Avenue from the subject site <br /> Drilling Company: Gregg Drilling, Inc of Martinez, California (C57 License <br /> No 485165) <br /> Drilling Dates. February 9 through 11, 2004 <br /> Drilling Methods. 8-inch and 10-inch hollow-stem augers <br /> Soil Sampling Methods Cambria logged soil from the borings using the Unified Soil <br /> Classification System and Munsell Soil Color Charts <br /> Encountered soils are described on the exploratory boring logs <br /> presented in Appendix B Soil samples from boring MW-12, <br /> and MW-13, above 60 fbg were collected at five-foot intervals <br /> Continuous sampling below 60 fbg was attempted in boring <br /> MW-13 however the recovery was poor due to the presence of <br /> flowing sands Soil samples were collected for sediment <br /> description, potential chemical analyses, head-space analysis <br /> and were screened for the presence of organic vapors using a j <br /> photo-ionization detector (PID) PID readings are recorded on <br /> the boring logs (Appendix B) <br /> Number of Borings. Two hollow-stem auger well borings were converted into <br /> groundwater monitoring wells MW-12 and MW-13 Boring and <br /> well specifications are described in Table 1 and locations are <br /> shown on Figure 2 <br /> Boring Depths The well boring for MW-12 was drilled to 47 fbg and the well <br /> boring for MW-13 was drilled to 84 fbg V <br /> Groundwater Depths. During drilling activities, groundwater was observed in well <br /> borings MW-12 and MW-13 at approximate depths of 38 5 and <br /> 40 fbg, respectively Blaine Tech Services, Inc (Blaine) of San <br /> Jose, California measured the groundwater depths in wells <br /> MW-1 through MW-13 and VEW-2 on February 27, 2004 <br /> 0854 4 <br />
