This Note discusses the application of the WTRISK computer program to a case study of selenium emissions from an existing coal-fired power plant in eastern Pennsylvania. Using alternative selenium concentrations in plant discharges, it calculates how much the incidence of selenosis might increase in the regional population that consumes either drinking water or fish from the Susquehanna River. The study's results indicate that the plant's selenium discharges should have a negligible effect on the incidence of selenosis in the regional population. The incremental exposure rates caused by these discharges are far below the threshold value calculated by the Environmental Protection Agency.
