The Center for Watershed Protection (Center) collaborated with local jurisdictions to comprehensively detect and quantify the nutrient and bacterial loads from nonstormwater discharges in two Mid-Atlantic subwatersheds. The Center followed a comprehensive procedure for detecting, tracking, and eliminating pollution sources that included (1) using threshold criteria, such as ammonia and bacteria to determine the presence of illicit sewage discharges; (2) estimating instantaneous pollutant loadings from the dry weather flowing outfalls; and (3) comparing the illicit sewage discharge pollutant load to the watershed load, as estimated from grab samples taken from a downstream, instream location.
