Information About Coronavirus (COVID-19)
With the recent news regarding coronavirus (COVID-19), we want you to know that this virus has no impact on the safety of your drinking water. Our water supply is locally sourced, with the majority of it coming from our protected Mt. Tam watershed. Your water is treated and routinely monitored to ensure there are no viruses or pathogens. We have plans in place to ensure that under any scenario, we will continue to provide you with safe, high-quality drinking water.
Every year, MMWD conducts more than 120,000 water quality and process control tests to ensure your water is safe to drink. MMWD looks for minerals, metals, salts and other similar chemicals. MMWD also tests for bacteria, herbicides, pesticides, endocrine disruptors, and industrial chemicals. In addition to the tests listed above, MMWD also tests your water to ensure the color and clarity are up to our high standards.
Tests are conducted from the time the water is collected in our reservoirs on the watershed, to the time the water arrives at your faucet. This includes testing in the lakes, at the inlet and outlet of the treatment plants, at key locations in the distribution system, and some at customers' taps. If you have any questions about your water quality, please contact our Water Quality Laboratory at 415-945-1550 or through email.
Public Health Goals
As a California water supplier, MMWD must prepare a special Public Health Goals Report every three years with information about contaminants that exceeded Public Health Goals (PHGs) or the U.S. EPA’s Maximum Contaminant Level Goals (MCLGs). PHGs are non-enforceable goals established by the CalEPA’s Office of Environmental Health Hazard Assessment and are not required to be met by any public water system. The U.S. EPA establishes MCLGs which, like PHGs, are non-enforceable goals.
MMWD’s PHG report, which summarizes water quality data for 2016, 2017 and 2018, was presented at a District Operations Committee meeting on October 18, 2019. If you have any questions regarding this report, please contact the Water Quality Lab at (415) 945-1550 or email firstname.lastname@example.org.
