Environmental Health Services takes ocean water samples at twenty locations along the coast on a weekly basis. (Sampling locations are listed below.) Samples are analyzed for three types of indicator bacteria, which at sufficient concentrations indicate the potential presence of bacteria that may cause human illness. The results are compared to standards established by the State. If any of the State standards are not met, a Health Advisory is issued.

A Health Advisory warns bathers to avoid water contact activities due to the presence of elevated levels of bacteria. An advisory spans fifty yards north and south of the area where the sample is collected. Beaches are posted with advisory signs and remain posted until sample results indicate that bacteria levels meet State standards.

This website is updated when weekly sample results become available. This information is also available on our hotline 788-3411.
