The Water Quality section tracks point and non-point source pollution from generation to treatment to its accumulation in surface and underground bodies of water and transport and decay in rivers. Instream water quality can be modeled within WEAP, or by linking to QUAL2K.
On the Water Quality Constituents screen you can turn on or off water quality modeling, and specify the list of constituents and how they are modeled.
The Water Quality section of the Data View includes data on Pollutant Decrease in Return Flows and Wastewater Treatment, both described below. Other water quality data are describe above in the Demand and Supply sections: Pollution generation by demand sites and catchments, River Water Quality, Reach Water Quality Parameters, Reservoir Water Quality and Groundwater Water Quality.
The following types of data are often useful:
Pollution discharges, their locations and quantities.
Non-point source pollution concentrations
Minimum water quality standards
Wastewater treatment plant ratings for pollutant removal
River water temperature in river reaches
Climate data
River flow-stage-width relationships
River length
Concentrations of water quality constituents in headflows, reservoir outflows, groundwater and surface water inflows
