i F <br /> U <br /> U. 1 <br /> P A G E 9 <br /> Ik I <br /> k <br /> As noted above for soil, the risk-based screening levels for ground water <br /> do not address potential cumulative exposures to multiple constituents_ <br /> However, cumulative exposures to ground water constiuents a <br /> tre not <br /> anticipated to pose an unacceptable risk for the reasons stated ,below: <br /> it <br /> • Residual ground water constituents were detected infrequently. <br /> ii 9 <br /> • The opportunity for exposure to ground water constituents!is limited. <br /> The calculated screening levels far exceeded any of the reported <br /> constituent concentrations. <br /> 1 HRA CONCLUSIONS <br /> Based on the site characterization data and on the HRA presented herein, <br /> the subject sites do not pose an unacceptable risk to human health under <br /> current and realistic future use conditions. Therefore, nolfurther action is <br /> warranted to address residual constituents in soil and ground .water at <br /> these properties. <br /> I, <br /> I; <br /> �3 333 <br /> II <br /> :f <br /> Ir <br /> 3� <br /> 4 i}. <br /> f <br /> r ' <br /> 13 I <br /> die I ' <br /> I�I, <br /> �l I <br /> II} <br /> 4 ' <br />� 11 <br /> f 't <br /> I, <br /> t <br />
