How to know when water is polluted

Bacterial pollution monitoring is conducted by the Washington Department of Health, the Washington Department of Ecology, and by some counties, tribes, and local municipalities. In a given area the monitoring is often well coordinated and done on a regular basis at various locations. Unfortunately, monitoring is expensive and is often only done on a monthly basis, which may not catch contamination quickly enough to prevent harm. Before you harvest shellfish call the hotline at 1-800-562-5632 to see the status of your beach or visit the Washington Department of Fish and Wildlife website at: wdfw.wa.gov/fishing/shellfish.
