CAMBRIA <br /> Sampling Methods Soils were electronically logged continuously using CPT <br /> equipment The soils encountered are described on the CPT <br /> boring logs presented in Appendix B Soil and groundwater <br /> samples from the borings were collected at various intervals for <br /> chemical analysis <br /> Number of Borings Two CPT borings were drilled during this investigation The <br /> CPT boring specifications are described in Table 1 and locations <br /> are shown on Figure 2 <br /> Boring Depths: CPT borings CPT-8 and CPT-9 were drilled to 150 fbg <br /> Groundwater Depths. A pore pressure dissipation test was conducted in CPT-8 at a <br /> depth of 123 20 fbg The test findings indicate the depth to <br /> groundwater in this boring was 24 3 fbg <br /> Soil Classification Soils types encountered while drilling are described on the CPT <br /> boring logs (Appendix B) <br /> Chemical Analyses- Soil and groundwater samples collected from borings CPT-8 and <br /> CPT-9 were analyzed for TPHg, benzene, toluene, ethylbenzene, <br /> and xylenes (BTEX), fuel oxygenates [methyl tertiary butyl <br /> ether (MTBE), tertiary amyl methyl ether, tertiary butyl alcohol <br /> (TBA), di-isopropyl ether(DIPE), ethyl tertiary butyl ether], and <br /> lead scavengers [1,2-dichloxoethane (1,2-DCA) and <br /> 1,2-dibromoethane] by EPA Method 8260B <br /> Soil Disposal Approximately 0 1 cubic yards of drill cuttings were generated <br /> during field activities and covered with plastic sheeting and <br /> stored onsite The soil was profiled for disposal and will be <br /> transported to Allied Waste Industries' Forward Landfill in <br /> Manteca,California for disposal <br /> 1399 4 <br />
