Beach Advisories or Beach Postings occur when at least one
bacterial standard from the Ocean Water Contact Sport Standards issued by the
California Department of Health Services, has been exceeded. Warning signs
alert the public of a possible risk of illness associated with water contact.
The placement of signs may be short term or more permanent where monitoring
indicates repeated contamination (e.g. from a storm drain). Warnings may be
posted where sources of contamination are identifiable and can be explained as
not of human origin (e.g., resident marine mammals or seabirds) or of an
unknown source. Click image to enlarge.
