2015 Annual Water Quality Report Now Available

Posted on July 16, 2015 at 3:18 PM by Ann Vallee

We are proud to report that our water continues to meet or surpass all state and federal drinking water standards. Our 2015 Annual Water is now available online in English and Spanish. The report summarizes the results of thousands of water quality analyses conducted by MMWD from January-December 2014.

MMWD takes many steps to ensure the water we deliver to your tap is of high quality. These steps include carefully managing our watershed lands and reservoirs, treating the water, operating and monitoring a complex distribution system, and maintaining and upgrading our facilities. Each year we conduct more than 120,000 water quality tests from watershed to faucet. This includes ongoing process control testing at our three treatment plants as well as laboratory testing.

MMWD reports the water quality information annually in compliance with requirements established by the State Water Resources Control Board Division of Drinking Water and the U.S. Environmental Protection Agency (EPA). The state and federal regulations require drinking water suppliers to test for more than 100 contaminants and to include in the report the test results for any contaminants found and at what levels. In 2014 we also tested for an additional 28 unregulated compounds as part of the Unregulated Contaminant Monitoring program administered by the EPA.

Printed copies of the Annual Water Quality Report can be requested by calling our Water Quality Lab at 415-945-1550.
