Marin Drinking Water Meets State Standards

In June, the Marin Municipal Water District mailed its annual water quality report to its 62,000 customers. The report, which details the level and types of contaminants found throughout the drinking water, is available at right.

The report is also available in Spanish here.

The majority of MMWD's water comes from the rainfall collected in its reservoirs, with the remaining 25 percent coming from the Russian River via Sonoma County Water Agency.

The Mt. Tamalpais watershed is most susceptible to contamination from recreational use. The Nicasio Reservoir is most susceptible to agricultural contamination. And the Soulajule Reservoir, which holds water for periods of drought and was not utilized in 2010, is at risk for mercury contamination from old mines in the area. Although there is no contamination from these sources found in any of the drinking water, according to MMWD, there are warnings about eating fish from the Soulajule Reservoir. Fish can accumulate levels of mercury from sediment, despite there being no mercury present in the water.

What do you think of the quality of water? Are you concerned? Does the annual report answer questions about possible contamination?
