r <br /> C A M B R I A <br /> description, potential chemical analyses, and headspace analysts <br /> Soil samples were screened for the presence of organic vapors <br /> using a photo-ionization detector (PID) The PID readings are <br /> recorded on the boring logs (Appendix B) <br /> Number of Borings. Three borings (SVE-1 through SVE-3) were converted into <br /> vapor extraction wells Boring and well specifications are <br /> described in Table 1 and their locations are shown on Figure 2 <br /> Boring Depths. Well borings SVE-1 and SVE-2 were drilled to 31 5 feet below <br /> grade (fbg) and boring SVE-3 was drilled to 36 5 fbg <br /> Groundwater Depths Groundwater was not encountered in the SVE well borings <br /> Soil Types Soil types encountered during drilling consisted of sand (SW <br /> and SP) to depths ranging from 26 to 28 fbg, underlain by clayey <br /> and sandy silt (ML) to the total explored depth of 36 5 fbg Soil <br /> types from the borings are recorded on the boring logs <br /> • (Appendix B) <br /> Chemical Analyses Selected soil samples from the well borings were analyzed for <br /> TPHg, BTEX, and fuel oxygenates (MTBE, di-isopropyl ether, <br /> TAME,ETBE, and TBA)by EPA Method 8260B <br /> Soil Disposal Approximately five cubic yards of soil were generated during <br /> field activities, stored onsite, and covered with plastic sheeting <br /> The stockpile was sampled and profiled for disposal It is <br /> currently pending transportation to Allied Waste Industries' <br /> Forward Landfill in Manteca, California for disposal <br /> Well Materials Wells SVE-1 through SVE-3 were constructed using four-inch <br /> diameter Schedule 40 PVC casing with a screen slot size of <br /> 0 020-inch and#2/12 Monterey sand <br /> Screened Interval Wells SVE-1 through SVE-3 are screened from 15 to 30 fbg <br /> Monitoring well construction details are presented on Table 1 <br /> and recorded on the exploratory boring logs (Appendix B) <br /> 0955 5 <br />
