Water Quality

Consumer Confidence Report

The Environmental Protection Agency (EPA) requires community water systems to deliver a Consumer Confidence Report, also known as an annual drinking water quality report, to their customers. These reports provide Americans information about their local drinking water quality summarizing information regarding source water, detected contaminants, compliance, and educational information.

The stated purpose is to improve public heath protection by providing educational material to allow consumers to make educated decisions regarding any potential health risks pertaining to the quality, treatment, and management of their drinking water supply.

In Zone 7's 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. "All water supplied during 2016 met the regulatory standards set by the State and federal governments and, in almost all cases, the quality was significantly better than required."

In July, Zone 7's offsite groundwater bank storage increased to 92,900 AF. By the end of the month, there were 242,000 AF in the local groundwater basin, of which 116,000 AF are considered operational storage (i.e. above historical low), and 6,000 AF of local runoff in Lake Del Valle.
Conservation in July 2017 was about 15% relative to July 2013 demands.
