The results from our most recent round of annual water quality tests show, once again, that the drinking water provided by MMWD is of superior quality. Details can be found in our 2011 Annual Water Quality Report, which documents that MMWD water meets, and in fact surpasses, all state and federal health regulations. We are proud to state that MMWD has never failed to meet health standards.
In order to keep the report simple and relevant, state and/or federal regulations specifically require drinking water suppliers to report test results for detected contaminants only. The contaminants reported include primary standards for contaminants that affect health; secondary standards for contaminants that affect the aesthetic properties of water, such as odor, taste and appearance; and certain additional contaminants for which standards do not exist. Each year MMWD conducts over 120,000 water quality tests from the watershed to the faucet.
The water quality information is reported annually in compliance with requirements established by the California Department of Public Health and the US Environmental Protection Agency and as a policy of MMWD to inform customers of the contents of their drinking water and water quality standards.
Printed copies of the report in English or Spanish can be requested from the MMWD Water Quality Lab at (415) 945-1550.
