Is our drinking water safe?

  • Your drinking water is safe. The water quality of municipal drinking water is continuously monitored and tested to ensure it meets or exceeds all state and federal drinking water standards.
  • The Sonoma County Water Agency (Water Agency) supplies water to more than 600,000 residents who live in the cities of Santa Rosa, Windsor, Rohnert Park, Cotati, Petaluma, Sonoma, North Marin Water District, Valley of the Moon Water District, and California-American Water.
  • The Water Agency is actively monitoring the watershed for any potential changes in water quality. To date, the Water Agency hasn’t seen any water quality issues associated with the recent wildfires.
  • Your water utility may supplement water supply with other local sources. For more information on drinking water quality in your neighborhood, visit
