Beach Advisories and Closures

In the State of Washington, the Public Health Officer is granted the authority for protecting people at publicly used recreational beaches.*

The BEACH Program works with local health authorities to evaluate heavily used marine saltwater beaches for fecal bacteria pollution problems. The results from weekly samples are used together with a beach survey to determine the level of risk of illness to the beach users. The BEACH Program recommends that when the results from beach sampling are above EPA’s criteria of 104 colonies of enterococcus bacteria per100 milliliters of water for a sample event or a geomean of 35 colonies of enterococcus per 100 milliliters of water for a five-week time period:

• The beach is resampled as soon as possible
• A visual survey of the beach is done to determine potential fecal sources
• Sample results, including resample results, are used to help the Public Health Officer determine if the beach is a menace to the public and a beach posting is needed.
