The Beach Environmental Assessment, Communication, and Health (BEACH) Program is a joint program of the Washington Departments of Health and Ecology that monitors water quality at recreational swimming beaches throughout Puget Sound and coastal Washington. Jefferson County staff and other local organizations collect water samples at public swimming beaches in Jefferson County and submit them to the state lab for testing. The most recent results are posted at the above linked website or on the beach closures map.
