C AMB R I A Mr Jeffrey Wong <br /> February 15, 2006 <br /> December 29, 2005 Blaine's well gauging data is included in <br /> Appendix C <br /> Soil Sampling Methods Cambria logged soil types using the Unified Soil Classification <br /> System and describes the encountered soils on the boring logs <br /> presented in Attachment D Cambria collected soil samples at <br /> 5-foot intervals for headspace analysts, soil description, and <br /> possible chemical analysis Cambria screened soil samples from <br /> the borings for the presence of organic vapors using a <br /> photo-ionization detector (PID) PID readings are recorded on <br /> the boring logs <br /> Soil Classification Soils encountered in these borings were consistent with soils <br /> encountered during previous investigations Soils consisted <br /> predominately of silts, sands, silty sand, and clay to the total <br /> explored depth of 95 fbg <br /> Chemical Analyses Selected soil samples from the borings and groundwater samples <br /> from wells MW-5, MW-6, and MW-7 were analyzed for TPHg, <br /> BTEX, fuel oxygenates (MTBE, di-isopropyl ether, ethyl tertiary <br /> butyl ether, TAME, and TBA), and lead scavengers (1,2- <br /> dichloroethane [1,2-DCA], and ethylene dibromide) by EPA <br /> Method 8260B by State-certified Severn Trent Laboratories, <br /> Inc (STL) of Pleasanton, California Groundwater samples from <br /> wells MWA through MW-4 were analyzed for TPHg, BTEX, <br /> and MTBE, and wells MW-1 and MW-4 were also analyzed for <br /> TBA by STL Certified laboratory analytical reports for soil are <br /> included in Attachment E, and the groundwater laboratory <br /> reports are included in Blaine's report (Attachment C) <br /> Soil Disposal Cambria temporarily stockpiled soil generated during the field <br /> activities on site and profiled the soil for disposal using <br /> analytical data from a previous investigation On <br /> December 19, 2005, Manley and Sons Trucking, Inc of <br /> Sacramento, California transported the soil to Allied Waste <br /> Industries' Forward Landfill in Manteca, California for disposal <br /> as non-hazardous waste Disposal confirmation for the soil is <br /> • included as Attachment F <br /> 5 <br />
