described in accordance with the Unified Soil Classification Systeme (see Boring Logs, <br /> Appendix A). The borings were backfilled to surface grade with portland cement. <br /> II <br /> 4.0 FINDINGS <br /> .o <br /> 4.1 Stratigraphy <br /> Backfill material was encountered to a depth of approximately 10 feet in both borings. <br /> Clayey silts and silty clays were encountered from 10 feet to the bottom of the borings (20 <br /> feet). Groundwater was not encountered during drilling. The borings Iogs are included in <br /> Appendix A. ,t <br /> 4.2 Laboratory Results of Soil Samples <br /> A total of four samples were analyzed for TPH as gasoline and diesel, BTE&X and total <br /> lead. No petroleum hydrocarbons were detected in any of the samples analyzed. Total lead <br /> was detected in all four samples at concentrations of 11 to 12 parts per million (ppm). The <br /> analytical results are summarized on Table 1. The laboratory report and chain-of-custody . <br /> are included in Appendix B. <br /> TABLE 1 <br /> ANALYTICAL RESULTS OF SOIL SAMPLES <br /> Bova Property <br /> 4445 East Fremont Street, Stockton, California <br /> (mg/kg) <br /> = Sample TPH as TPH as Benzene Toluene Ethyl- xylenes Total <br /> ID Gasoline Diesel benzene Lead <br /> BM1-10 ND ND ND ND ND ND 11 <br /> BM1-15 ND ND ND ND ND ND 11 <br /> BM2-15 ND ND ND ND ND ,ND 11 <br /> 2- 0 ND ND ND ND ND ` <br /> BM ND 12 2 � <br /> mg/l8 = pans per million(ppm) <br /> KD = Done Detected <br /> 5.0 CONCLUSIONS & RECOMMENDATIONS <br /> No petroleum hydrocarbons were detected in soil samples collected during this investigation. <br /> Concentrations of total lead detected in the soil samples are consistent with background <br /> levels observed throughout the region, and are below allowable regulatory standards.
