A M B R I A <br /> Cambria submitted the requested work plan on March 5, 2004, and the results of this work are <br /> presented below <br /> INVESTIGATION RESULTS <br /> Personnel Present: Cambria geologist Scott Lewis directed the field activities, <br /> working under the supervision of California Professional <br /> Geologist Joe Neely <br /> Permits Permit Nos 37951, 40706, and 40707 were obtained from <br /> SJCEHD (Appendix A) <br /> Drilling Company Gregg Drilling and Testing Inc and Gregg In Situ, Inc (Gregg) <br /> of Martinez, California(C57 License Nos 485165 and 656407) <br /> Drilling Dates June 3 and 4, 2004 and December 27 to 29, 2004 <br /> Drilling Method: Cone Penetration Test(CPT)and hollow-stem auger(HSA) <br /> Number of Bonngs Five CPT borings (SB-5 through SB-9) and four HSA borings <br /> (MW-6 through MW-9) were drilled Boring specifications are <br /> described in Table 1 and the boring and well locations are <br /> shown on Figure 2 <br /> Boring Depths. Borings S13-5 through SB-9 were drilled to 100 feet below grade <br /> (fbg) and borings MW-6 through MW-9 were drilled to 53 fbg <br /> Soil Sampling Methods Cambria logged soil types from borings (MW-6 through MW-9) <br /> using the Unified Soil Classification System and Munsell Soil <br /> Color Charts Soil samples were collected at 5-foot intervals for <br /> soil description, potential chemical analyses, and headspace <br /> analysis Soil samples were screened for the presence of organic <br /> vapors using a photo-ionization detector (PID) The PID <br /> readings are recorded on the boring logs (Appendix B) <br /> Soil types from borings (SB-5 through SB-9) were logged using <br /> . CPT electronic logging equipment No soil samples were <br /> collected from the CPT borings The CPT boring logs are <br /> 1511 2 <br />
