steel sleeve into undisturbed soil with the slide-hammer assembly. When the stainless steel sleeve <br /> had been driven six inches past the bottom of the borehole,the stainless steel sleeve was dislodged <br /> by manually sliding the slide-hammer upwards toward ground surface. When the stainless steel <br /> sleeve has been removed from the borehole, the brass sample tubes are sealed with Teflon®tape <br /> and plastic end caps. The sealed sample tubes were then labeled with unique identification numbers, <br /> placed in Ziploc ® bags, and stored in a chest cooled with ice prior to delivery to Priority <br /> Environmental Laboratory of Milpitas, California, a State of California-certified laboratory for <br /> analysis. The soil samples were analyzed for HVOCs using U.S. EPA Method 8010. <br /> Each borehole was backfilled and compacted with the soil cuttings generated at each sample <br /> location, and the ground surface was repaired with neat cement. <br /> LITHOLOGIC CONDITIONS <br /> Soils underlying the Property consist of very hard,very firm, sticky and plastic clays. The soils were <br /> dark and moist at the depth sampled. <br /> ANALYTICAL LABORATORY RESULTS <br /> Target HVOCs were not reported above laboratory detection limits in soil samples submitted from <br /> approximately 2 t/z feet bgs at SB-1, SB-2, and S13-3. Detection limit concentrations for individual <br /> compounds are presented on copies of the laboratory data sheets attached to this report. <br /> CONCLUSIONS AND RECOMMENDATIONS <br /> Analytical laboratory results indicate that target HVOCs are not present above laboratory reporting <br /> limit concentrations in soil samples submitted from SB-1 through SB-3. <br /> Based on the results of this investigation, CERES does not recommend further investigations at this <br /> time. <br /> LIMITATIONS <br /> The conclusions and recommendations presented in this report are limited by the scope of work <br /> conducted for this assessment and are based on information provided by: <br /> • Wells Fargo Bank; <br /> • Priority Environmental Laboratory; and <br /> • Observations of CERES personnel. <br /> CERES Environmental 3 Project A563-02 <br /> WFB ENV.03499 June 16,1996 <br />
