Meets to consider new legislation surrounding water utilities’ disinfection methods

The report, which American Water Works Assn. (AWWA) Deputy Executive Director for Government Affairs Tom Curtis called "incomplete and misleading," was released by the Center for American Progress. It listed 235 drinking water facilities and 315 wastewater facilities in 47 states that switched from gaseous chlorine to liquid bleach and ultraviolet light for disinfection.

AWWA said it believes that the choice of disinfectants must remain a local decision.
