This project was inititaed on June 1, 1995 for the purpose of stimulating efforts towards the reduction of point source nutrient discharges to the waters of the Chesapeake Bay Watershed. Prior to the project a few engineering firms had developed reports wherein they estimated the total costs for biological nutriemt removal (BNR) retrofits at the wastewater treatment plants (WWTP) throughout the Watershed. The estimates indicated that implementation of nutrient removal throughout the Watershed would be very costly.
