This annual report summarizes water quality monitoring data and provides an update on Zone 7's Water Quality Management Program (WQMP), which the agency established with its retailers in 2003. The WQMP provides the basis for identifying ways to meet anticipated future regulations, reduce public health risks, and improve the delivered water quality -- especially its taste, odor and hardness, by effectively managing water quality issues, guiding operations, upgrading or improving facilities, and providing new facilities when necessary. 

In this annual water-quality report, you will find specific data about regulated and unregulated contaminants. You will also learn more about where your water comes from, what Zone 7 does to monitor its quality, and how it manages the water supply and protects its quality.
