Ocean Water Quality Monitoring

Sonoma County has approximately 64 miles of coastal beaches. In order to protect the health of the public, weekly samples are collected and tested between April 1 and October 31 by the Department of Health Services to monitor bacterial levels.

Ocean water samples are collected at beaches that are visited by 50,000 people per year and are adjacent to storm drains, creek or rivers. Seven beaches in Sonoma County meet this criteria.

 

Weekly Ocean Water Quality Test Results

ADVISORY Bacterial levels have exceeded State standards. Contact with water may cause illness and should be avoided.

CLOSED Significant risk to health. Avoid any contact with the water until further notice.

Note: Unless indicated, bacterial levels shown are below State standards. There are no restrictions to water contact activity.
