Water Quality from Source to Tap
Water Quality from Source to Tap
Water quality refers to the chemical, physical, and biological properties of water. Water quality requires management from source to tap, and certain standards are enforced to protect public health.

Hypochlorite Assessment Model
This predictive modeling tool provides guidance on the expected levels of perchlorate and chlorate in stored bulk hypochlorite solutions. The calculations are based on predictive algorithms derived from earlier research on the subject and local, user-defined inputs (e.g., storage conditions, ionic strength, ambient temperature).
The output is intended to help utilities determine the appropriate storage-time/life-cycle for the hypochlorite solution based on the expected rate of degradation and contaminant formation. Such a tool will better enable utilities to manage supply and/or take other countermeasures to mitigate further degradation that could cause an exceedance of a regulated contaminant standard.

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.
Volunteer with the AWWA Technical Committee
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.
