Abstract:

Steady state methods for calculating water quality based effluent limits (WQBELs) depend on selecting critical conditions of treatment plant effluent and receiving water flowrate and water quality. In the case of heavy metals and ammonia, the critical conditions for hardness, and pH and temperature, are also selected to calculate the respective criteria. Concurrently selecting the critical conditions for flow, concentration, and ambient conditions may lead to WQBELs overprotective of beneficial uses and at levels impossible to meet through available treatment technologies short of reverse osmosis. Dynamic modeling incorporates the observed receiving water and effluent characteristics to more accurately represent the effluent limitations required to provide the intended level of water quality protection. Where maximum recorded concentrations are extremely rare events or there is available dilution, the dynamic model derived effluent limitations may be considerably higher than the concurrent worst case condition steady state limits.
