DRAFT <br /> 1 <br /> that the elevated excess cancer risk may be due to the localized presence of PAHs in soil <br /> in <br /> one soil boring collected at a depth of 1 foot below ground surface. <br /> For lead, the maximum lead concentration of 360 mg/kg in soils was less than the child <br /> receptor-based lead in soil target concentration and the industrial receptor-based lead in <br /> soil target concentration. Lead concentrations in soil at Area 4 ranged from 6 to 360 <br /> mg/kg. Consequently, the soil lead concentration in Area 4 does not appear to represent a <br /> 1 <br /> potential health hazard. <br /> 1 <br /> 1 <br /> l <br /> 1 <br /> i <br /> t <br /> t <br /> ' SOMA 99-2218 <br /> 22 12/10/99 <br />
