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.
The Tacoma-Pierce County Health Department sampled six beaches weekly in Pierce County during the 2022 season.
See details on each beach below.
Dash Point Metro Park beach was sampled 16 times during the 2022 sampling period. This beach had excellent quality, meeting the swimming standard for all periods sampled.
Jack Hyde Park beach was sampled 15 times during the 2022 sampling period. This beach had two events with elevated results. On June 6 and July 18, samples were in the advisory range but subsequent sampling showed that bacteria levels were in the safe swimming range. All other sampling events met the swimming standard.
During the 2022 monitoring season, Purdy Sandspit County Park beach was sampled 16 times. This beach had excellent water quality, meeting the swimming standard for all periods sampled.
Sunnyside Beach Park was sampled 16 times during the 2022 sampling season. This beach had excellent water quality, meeting the swimming standard for all periods sampled.
Titlow Park beach was sampled 15 times during the 2022 sampling season. This beach had very good water quality and met the swimming standard for all periods sampled.
During the 2022 monitoring season, Ruston Way Waterfront Park beach was sampled 15 times. This beach had excellent water quality, meeting the swimming standard during all periods sampled.
Data summary: Bacteria results compared to standards
The chart below summarizes the bacteria levels at Pierce 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.
