MANAGEMENT OF PATHOGENS AND INDICATOR ORGANISMS IN URBAN AREA WATERSHEDS: OPTIMIZING WET-WEATHER DISINFECTION WITH ADAPTIVE TECHNOLOGIES
Abstract:Over the last decade, substantial research has been conducted to characterize, control and optimize cost-effective mitigation of urban area wet weather pathogens. Disinfection approaches including chlorination and UV disinfection were tested in Atlanta and Columbus, GA and Syracuse, NY under variable wet weather pollutant loadings following treatment with multiple CSO technologies. This paper summarizes the most significant common findings pertinent to effective inactivation of bacteria from these three studies and applications to the management of pathogens in other urban area (non-CSO) watersheds through the use of adaptive technologies including a BMP incorporating flow control, high-rate filtration and UV disinfection to support measurable improvement objectives under EPA's TMDL program.
