Abstract : This document contains the baseline human health risk assessment and the ecological risk assessment (ERA) for the Oliktok Point Distant Early Warning (DEW) Line radar installation. Eight sites at the Oliktok Point radar installation underwent remedial investigations (RIs) during the summer of 1993. The presence of chemical contamination in the soil, sediments, and surface water at the installation was evaluated and reported in the Oliktok Point Remedial Investigation/Feasibility Study (RI/FS) (U.S. Air Force 1996). The analytical data reported in the RI/FS form the basis for the human health and ecological risk assessments. The primary chemicals of concern (COCs) at the eight sites are diesel and gasoline from past spills and/or leaks, chlorinated solvents, metals, and polychlorinated biphenyls (PCBs). The general location of the Oliktok Point radar installation is shown in Figure 1-1. The eight sites investigated and the types of samples collected at each site are presented in Table 1-1. 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 eight sites investigated during the RIs. 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.
