Description:
The United States Environmental Protection Agency’s (EPA) Water Modeling Workgroup (WMW) provides support for core surface water quality modeling tools used in Clean Water Act programs. The WMW identified a set of 18 separate surface water modeling applications that are currently applied to support development of Total Maximum Daily Load (TMDL) plans, assess permit conditions for National Pollutant Discharge Elimination System (NPDES) facilities, evaluate policy and water quality effects of potential actions, and conduct other water quality analyses. The WMW directed Tetra Tech to perform an assessment of the current maintenance and support status of each modeling tool to facilitate the identification of gaps in support or other activities that might warrant future WMW activity. This report summarizes the findings of this review of the maintenance and support status of the following modeling applications.
