C A M B R I A <br /> groundwater beneath the site Cambria subirutted the requested work plan on May 10, 2002, and <br /> the results of this work are presented below <br /> INVESTIGATION RESULTS <br /> Personnel Present Cambria geologist Scott Lewis directed the field activities, <br /> working under the supervision of California Registered <br /> Geologist Joe Neely <br /> Permit: Permit No 32130 was obtained from SJCEHD (Appendix A) <br /> Drilling Company: Gregg Drilling and Testing, Inc of Martinez, California <br /> (C57 License No 485165) <br /> Drilling Dates. December 10 through 12, 2002 <br /> Drilling Method Eight-inch hollow-stem augers <br /> Soil Sampling Methods: Cambria logged soil types from the borings using the Unified <br /> Soil Classification System and Munsell Soil Color Charts Soil <br /> samples were collected at five-foot intervals for soil description, <br /> potential chemmcal analyses, and headspace analysis Soil <br /> samples were screened for the presence of organic vapors using <br /> a photo-ionization detector (PID) The PID readings are <br /> recorded on the boring logs (Appendix B) <br /> Number of Bonngs• Five hollow-stem auger borings (MW-1 through MW-5) were <br /> converted into groundwater monitoring wells Boring and well <br /> specifications are described in Table 1 and locations are shown <br /> on Figure 2 <br /> Boring Depths. Well borings MW-1 and MW4 were drilled to 56 5 feet below <br /> grade (fbg) and well borings MW-2, MW-3, MW-5 were drilled <br /> to 53 fbg <br /> Groundwater Depths: During drilling activities, groundwater was observed in well <br /> . borings MW-1 through MW-5 at a depth of approximately <br /> 47 fbg Blaine Tech Services, Inc (Blaine) of San Jose, <br /> 1511 2 <br />
