Description:
Many drinking water utilities in the USA are considering alternatives to chlorine for disinfection in order to comply with federal regulations regarding disinfection by-products. An evaluation is thus needed of the potential risks associated with the use of alternative disinfectants relative to those posed by chlorine. Two pilot-scale drinking water plant studies were conducted using a variety of disinfection schemes, incorporating ozone, monochloramine, chlorine dioxide, and chlorine. Concentrates of these water samples were tested, using the Ames Salmonella assay, to compare the relative mutagenic potencies of the water samples following the different methods of disinfection.
