Keeping beaches safe

The Beach Environmental Assessment, Communication & Health (BEACH) Program ensures that marine water is safe to swim and play in and informs the public if water doesn't meet swimming standards.

From Memorial Day through Labor Day in 2020, we sampled 63 public high-use beaches statewide, either weekly or biweekly, for enterococcus, a type of fecal bacteria. High enterococcus levels are linked to swimmer illness.

Pierce County saltwater swimming beaches

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.

Table: Calculated geometric mean and statistical threshold value at Pierce County beaches (in enterococcus per 100 mL) for 2020.
