AWWA JAW62273

Secondary disinfection practices of water utilities, particularly the use of chloramines, are at the center of several national drinking water policy discussions. As a response to this ongoing dialogue, AWWA commissioned the Secondary Disinfection Practices Survey -- a web-based survey of water utilities -- to determine the percentage of utilities currently using chloramines and those intending to convert to the use of chloramines in the future. Results of the survey indicate 68% of utilities currently use chlorine for secondary disinfection, 29% use chloramines, and 3% use no secondary disinfectant. The results of this survey serve to inform national drinking water policy discussions (i.e., the Stage 2 Disinfectants/Disinfection Byproducts Rule) and to support the continued increase in the use of chloramines.
