SUBSURIIACE INVESTIGATION REPORT <br /> Beacon Station No. 502 <br /> 35 North Cherokee Lane <br /> Lodi, California <br /> Delta Project No. 40-92-813 <br /> Page 2 <br />' to approximately 34 feet, and sand and silty sand to depths greater than 50 feet. Ground water was not <br /> encountered. Soil boring logs with descriptions of the various soils encountered and PID readings of soil <br />' samples are presented in Appendix B. <br />' 4.0 ANALYTICAL RESULTS <br /> Soil samples were collected from soil boring SBA at depths of 10, 20, 30, 40, 45, and 50 feet, from soil <br /> boring SB-2 at depths of 15, 20, 30, 40, 45, and 50 feet, and from soil boring S13-3 at depths of 15, 20, <br /> 25, 30, 40, 45, and 50 feet. The samples were submitted to a state-certified laboratory for analysis of <br /> benzene, toluene, ethylbenzene, and xylenes (BTEX), total petroleum hydrocarbons (TPH) as gasoline, <br /> and TPH as diesel. In addition, the soil samples collected from soil boring SB-3 at depths of 15 and <br />' 20 feet were analyzed for Volatile Organic Priority Pollutants, and a soil sample collected from the <br /> stockpiled drill cuttings was analyzed for BTEX, TPH as gasoline, TPH as diesel, and organic lead. <br /> Analytical results are summarized in Table 1, and copies of the analytical laboratory reports are presented <br /> in Appendix C. <br /> TABLE 1 <br /> SOIL SAMPLE ANALYTICAL RESULTS <br /> APRIL 29, 1993 <br /> Concentrations in parts per million(ppm) <br /> Soil Ethyl- Organic <br />' Borin Depth ft Benzene' Toluenes benzenes Xylenes' TPHgb TPHd` Lead <br /> SB-1 10 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 20 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br />' 30 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 40 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 45 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 50 <0.005o <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> SB-2 15 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 20 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 30 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 40 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 45 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> 50 <0.0050 <0.0050 <0.0050 <0.0050 <0.50 <1.0 <br /> RPT l03.SJH <br />
