“…Potential risksd to human health fiom exposure to the COPC at the WCF were evaluated using a two-phased approach (Rood 1994). The frrst phase used the groundwater screening model and computer code, GWSCEEN (Rood 1994) and conservative assumptions, (see box) to estimate groundwater concentrations of COPC.…”

“…The frrst phase used the groundwater screening model and computer code, GWSCEEN (Rood 1994) and conservative assumptions, (see box) to estimate groundwater concentrations of COPC. Screening model values of four COPCs exceeded the lower threshold of the NCP target risk range of 1 x 1 Od (Rood et al 1996).…”
