"A study was conducted to predict toxic waste concentrations in community drinking waster supplies along the Ohio and Kanawha Rivers between Charleston, West Virginia, and Cincinnati, Ohio, using QUAL-II, a water quality simulation model. Specifically a toxics screening method was developed that can close the potential gap in the loop between water pollution control and water consumption. The project was a response to the lack of methods for identifying and assessing communities whose water supplies were vulnerable to excessive chloroform and synthetic organics resulting from industrial pollution and urban and agricultural runoff. The most important factors to consider in identifying vulnerable communities are potency and persistence of the pollutants, amount and timing of discharge of pollutants, storage times of utilities, and relative location of point sources and community intakes."
