ROUT is a deterministic modeling system that predicts chemical concentrations in rivers and streams that receive discharges from POTWs system also predicts drinking water intake concentrations. Over 500,000 river miles are systematically routed through the 18 major hydrologic regions of the continental US. The system uses several US EPA databases (Needs-POTW File, IFD, REACH, RCHPUB, GAGE and DRINKS). Predicted concentrations in river reaches and drinking water intakes come from loads to 11,500 POTWs which discharge to surface waters. ROUT outputs include statistical distributions of concentration by river mile and by population for drinking water facilities as well as hard copy reports of selected portions of detailed output data. A GIS (geographical information system, ARC-INFO/ARCVIEW) interface was coupled to ROUT to provide readily interpretable visualizations of the geographic influences on ROUT outputs. Concentration distributions for river reaches were determined for each US county. Effects of loading factor and biodegradation rates on ROUT/GIS outputs and their role in risk assessment will be discussed.
