Advisory Signs
Beach
advisory signs are posted when sample analysis results indicate
bacteria levels above the established standard, signifying the possible
presence of disease-causing organisms. These advisories are recommendations
to the public to avoid water contact at the beach until further
analyses reveal safe conditions.
Advisory signs are removed when
sample analysis results return to below the established standard,
and the 5-sample geometric mean levels are acceptable.
