The WADSY-Q computer program was developed as a tool to analyze water quality patterns in water distribution systems with multiple sources. The program calculates the concentrations of conservative parameters at any point in a modeled network, for steady-state conditions and known source concentrations. The program provides an efficient means of evaluating the water quality impacts of supply alternatives being considered to meet future demands. This information helps provide a more complete picture of benefits and costs so that prudent management decisions can be made.
