Thurston County annual BEACH report

Keeping beaches safe

The Beach Environmental Assessment, Communication & Health, or BEACH, Program ensures that marine water is safe to swim and play in and informs the public if water doesn't meet swimming standards. Sampling takes place from Memorial Day to Labor Day. During this time, you can check out current water quality conditions on the swimming map.  

Two beaches in Thurston County were monitored weekly during the swim season in 2023. Burfoot County Park was sampled by Thurston County Public Health and Social Services. Squaxin Park was sampled by Surfrider volunteers.

See details on each beach below.

Data summary: Bacteria results compared to standards

The chart below summarizes the bacteria levels at Thurston County beaches in relation to the EPA swimming standard or saltwater swimming criteria. Beaches are considered unsafe for swimming when the geometric mean of enterococcus/100 mL of water is greater than or equal to 30 and the statistical threshold value of enterococcus/100 mL is greater than or equal to 110. We issue a public swimming advisory when enterococcus levels exceed 104 per 100 mL of water.
