Beach Water Quality Information

Community Development Agency

The Marin County Environmental Health Services successfully wrapped up the FY 2023-2024 annual beach monitoring program. At present, we've concluded our beach water sample collections. Our weekly water sampling will resume in the first week of April 2024 and will persist through the end of October.

Thank you for your part in ensuring the public's health at our local beaches, especially during these unprecedented times.
