The incidence of waterborne disease outbreaks attributed to opportunistic human pathogens that are not regulated by the EPA appears to be increasing compared to infections caused by traditional fecal-borne pathogens. This research will focus on reduced selection for opportunistic bacterial pathogens during drinking water treatment with a particular emphasis on non-tuberculous mycobacteria (NTM). Specifically, the research team hopes to optimize filter backwashing procedures to reduce selection for disinfectant-resistant, opportunistic pathogens, while maintaining or improving conventional filtration performance parameters.
