Harmful Algal Bloom Monitoring

FWC Red Tide Monitoring — These data from the Florida Fish & Wildlife Conservation Commission represent the most recent eight (8) days of sampling location points for the phytoplankton that causes red tide, Karenia brevis. These data are exported daily at 4:45 PM Eastern Time from the HAB Database, which provides information on the presence and absence of Karenia brevis. More Information »
Algal Bloom Sampling Status — FDEP's and partner agencies' real-time sampling updates for harmful algal blooms (HABs) throughout Florida. Data are filtered to show results for the most recent 4 months. More Information »

Bacteria Monitoring

Units used to report bacteria monitoring results may be Colony-Forming Units (CFU) or Most Probable Number (MPN) or Membrane Filter (MF) based on the analysis method. All of these units represent the number of bacteria estimated to be present within a 100-milliliter sample of water.

FLHEALTH — The Florida Healthy Beaches program is administered by the Florida Department of Health and its county health departments. It protects beachgoers from conditions unsuitable for swimming by sampling beach water and providing accurate and up-to-date explanations of the results. Sampling is performed biweekly to detect Enterococcus bacteria, which can come from a variety of natural and human-made sources. These include pet waste, livestock, birds, land-dwelling and marine wildlife, stormwater runoff, and human sewage from failed septic systems and sewage spills. These data are also made available on the Florida Department of Health website. More information » Download Historic Data
Value Qualifiers:
- U: Less than 4 colonies are present.
- B: Additional qualifiers may apply to the reported data.
- Z: "too numerous to count" The number of colonies present prevented an actual count. The data reported is an estimate based on the maximum number of colonies that can be counted on a plate times the dilution used.

Public Notices of Pollution

Section 403.077, Florida Statutes, defines a "reportable release" and requires the reporting of any "release or discharge of a substance from an installation to the air, land, or waters of the state which is discovered by the owner or operator of the installation, which is not authorized by law,and which is reportable to the State Watch Office within the Division of Emergency Management pursuant to any department rule, permit, order, or variance." The incidents shown here were reported to the State of Florida by public agencies and private facilities via a form on the FDEP website. Results show all notices of pollution provided by the FDEP datasource in the last 30 days. More information »
