Description
Summary:Intensive water quality surveys were conducted on the West Fork of the White River before and after implementation of AWT processes in Indianapolis, Ind. AWT addition substantially improved river water quality (ammonia nitrogen and DO concentrations). River ammonia reductions resulted in an apparent shift from zero- to first-order nitrification kinetics. Calibration of a modified Streeter-Phelps model with several DO profiles indicated that benthic respiration was a major DO sink in the White River and that implementation of AWT facilities significantly reduced this demand.
