Florida Healthy Beaches – Water Quality Monitoring

Florida Department of Health in St. Johns County Environmental Public Health Program


The Florida Department of Health in St. Johns County Environmental Public Health Service Center conducts beach water sampling at several beach locations throughout the county. Beach water is routinely analyzed for levels of the enteric bacterial indicator Enterococci. Test results are rated “Poor”, “Moderate”, or “Good” and are on total bacteria counts that are detected only through laboratory analysis. During instances when testing identifies poor water quality, a warning and/or advisory sign is posted at the specific beach location and a public service announcement is issued.

St. Johns County Beach Sample Results from routine bacterial monitoring are available for public viewing at the Florida Healthy Beaches Program. For information on other water quality issues please see the following:
