“…The focus is on contaminants of potential concern (COPCs) that were identified in previous human health risk screening reports ("able 5.1). In their screening assessment, Hoffman et al (1991) identified PCBs in fish and external exposure to radiation from lnCs in dredged sediments as exposure pathways and contaminants that are of potential concern. Cook et al (1992) confirmed the exposure pathways and COPCs based on CRRI Phase 1 data.…”

“…Although no air monitoring data were available for the LWBR area, the quantity of fugitive dust generated by the wind was empirically derived by the method described in Eckerman and Young (1980). This method was also used in the previous screening risk assessments of Hoffman et al (1991) and Cook et al (1992). The risk assessment equations and parameter values are given in Table A.6.…”

“…An important consideration in this decision was that practical remedial alternatives for LWBR are extremely limited (Radian Corp. 1993). The only human health risks identified in previous screening-level risk assessments (Suter 1991, Hoffman et al 1991, Cook et al 1992 appeared to be readily mitigated by existing institutional controls and advisories established by federal and state law. It was recognized that these controls were likely already protective of human health, unless the baseline risk assessment identified new or greater risks than had been previously identified.…”

Contamination at Superfund sites can involve mixtures of chemicals and radionuclides in a variety of environmental media. Determining priorities for evaluation and remediation of various contaminants is an important part of the initial phases of any site investigation. An effective screening analysis at the beginning of the project can help by identifying both those situations in need of immediate remedial attention and those which require further sampling and evaluation. The screening approach discussed here is made up of two sets of calculations designed to provide upper- and lower-bound estimates of health risk to individuals likely to receive the highest exposures. This approach allows rapid identification of contaminants which pose a negligible risk and can be assigned a low priority for remedial attention or which pose a substantial risk and should be given the highest priority for appropriate remediation efforts. Contaminants designated as neither high- nor low-priority should be investigated in more detail prior to making decisions regarding the need for or method of remediation. The utility of this approach has already been demonstrated in the evaluation of contamination in the Clinch and Tennessee River systems originating from historical operations of atomic weapons and energy research facilities near Oak Ridge, Tennessee.
