The purpose of this risk assessment report is to determine the potential public or environmental exposures and risks associated with constituents released to the environment as a result of operations at the S-3 Waste-Management Area (S-3 WMA). The S-3 WMA is located at the southwest end of the Y-12 Plant, but well within the DOE reservation. This risk assessment report is divided into five major sections: site characterization, constituent characterization, exposure assessment, hazard evaluation, and risk assessment. The ground water impacted by waste constituents from the S-3 WMA discharges to Bear Creek and East Fork Poplar Creek within the confines of the DOE reservation. Waste constituents released from the S-3 WMA have been detected in the ground water, surface water, and sediments. Eight constituents were identified as representing the greatest potential for exposure and hazard. These were barium, cadmium, mercury, nickel, nitrate, uranium, Tetrachloroethene (PCE) and trichloroethene (TCE). Overall, the S-3 WMA currently presents a low level of potential exposure and hazard to the public, but a moderate level of continued hazard to the aquatic communities of Bear Creek and East Fork Poplar Creek. Figures, tables, and references are included.
