| Abstract |
This study is directed toward the overall issue of determining before and after responses of river systems following installation of improvements in municipal wastewater treatment facilities. The basis objectives of the study are threefold: To determine the extent of the data base for water quality before and after improvements and compile such data; To compare the before and after data to determine changes in water quality after treatment improvements; To evaluate the ability of calibrated wasteload allocation water quality models to predict water quality after improved treatment. |
