This document contains the baseline human health risk assessment and the ecological risk assessment ERA for the Point Lonely Distant Early Warning DEW Line radar installation. Twelve sites at the Point Lonely radar installation underwent remedial investigations RIs during the summer of 1993. The Vehicle Storage Area SS14 was combined with the Inactive Landfill because the two sites were essentially co-located and were sampled during the RI as a single unit. Therefore, 11 sites are discussed in this risk assessment. The presence of chemical contamination in the soil, sediments, and surface water at the installation was evaluated and reported in the Point Lonely Remedial InvestigationFeasibility Study RIFS. The analytical data reported in the RIFS form the basis for the human health and ecological risk assessments. The primary chemicals of concern COCs at the 11 sites are diesel and gasoline from past spills andor leaks, chlorinated solvents, and manganese. The 11 sites investigated and the types of samples collected at each site are presented. The purpose of the risk assessment is to evaluate the human health and ecological risks that may be associated with chemicals released to the environment at the 11 sites investigated during the RI. The risk assessment characterizes the probability that measured concentrations of hazardous chemical substances will cause adverse effects in humans or the environment in the absence of remediation. The risk assessment will be used to determine if remediation site cleanup is necessary and, if so, to rank sites for remedial action.
