LABORATORY ANALYSIS <br /> All soil samples collected during this soil remediation project were analyzed by Pace <br /> Laboratories of Novato, California, a state certified laboratory Laboratory data is <br /> summarized in Table 1 through Table 11 The tables are presented in order of collection <br /> date Tables 1, 8 and 9 summarize the tank pit,pump island and waste oil pit confirmation <br /> samples,respectively The remaining tables, Tables 2 through 7, and 10 through 11 <br /> summarize the soil stockpile analytical data <br /> TANK EXCAVATION AREA <br /> The soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPH-g) by <br /> EPA Method 8015, benzene, toluene, ethylbenzene and xylenes (BTEX) by EPA Method <br /> 8020 Lead was analyzed by EPA Method 6010/200 7 ICP A summary of the tank pit <br /> confirmation samples is presented in Table 1 TPH-g was not detected m the soil samples <br /> Samples S-2 and S-3 contained benzene at 8 1 and 9 1 parts per billion (ppb) at 115 and <br /> 110 feet below ground surface, respectively <br /> PUMP ISLAND AREA <br /> The soil samples were analyzed for TPH-g, BTEX and lead (See Table 8) TPH-g was <br /> detected in four soil samples P-1, P-2 P-3 and P-5 at levels of 25, 210, 53 and 26 ppm, <br /> respectively Sample PI-2 contained BTEX at levels of 900, 3,900, 2,600 and 25,000 ppb, <br /> respectively BTEX compounds were detected at lower levels in samples PI-1, PI-3, and <br /> PI-5 The STLC lead levels ranged from 16 to 37 ppm <br />
