Disinfection Byproducts
Disinfection Byproducts
Disinfection is a required step in drinking water treatment that is enforced to protect public health. However, when selecting the appropriate disinfectant for a specific system, it is important to note that disinfectants react with organics and inorganics in source water to form disinfection byproducts, or DBPs.
The challenge that must be addressed in the water treatment process is providing adequate protection from microbial pathogens through disinfection, while simultaneously minimizing the health risks associated with DBP formation.

AWWA Policy Statements
AWWA’s policy statements are brief statements on protecting and improving water supply, water quality, management, and the interests of the public and the environment. They are written by consensus, subject to review and comment by AWWA committees, councils, and members. Because they represent AWWA’s position on these matters, they are approved by the AWWA Executive Committee of the board of directors.
Technical Committee Engagement
AWWA members are recognized globally for their industry expertise and their generosity in sharing that expertise for a better world through better water. AWWA members participate in committee activities, developing conference programs, writing technical manuals, developing standards, creating educational content, and contributing to AWWA publications. Committee members primarily interact through conference calls, emails, and face-to-face meetings at conferences and events.
