South Florida Algal Bloom Monitoring and Response

Algal-Blooms_RButton_3

The Report Algal Blooms hotline and online submission form are for freshwater blue-green algae reports only. To report red tide blooms, visit the FWC Red Tide Status website.

Sampling Schedule

DEP reviews citizen reports of algal blooms received via the online reporting form or hotline and coordinates with other agencies who are also sampling – SFWMD, SWFWMD, FWC and Lee County – to determine the sampling team to respond based on the location of the bloom relative to the sampling schedule for that day. Additional entities have reached out to offer sampling support and are added to the schedule as needed.

The department, water management districts and FWC routinely survey and sample locations in South Florida, and are prepared to collect samples if algae is present.

Sampling Results

To date, a majority of the results continue to indicate low to extremely low levels of toxins. All results are reported to the Florida Department of Health (DOH), the Florida Fish and Wildlife Conservation Commission (FWC) and the Florida Department of Agriculture and Consumer Services (DACS).

A water droplet on the map indicates a site visit for observation or sample collection. Clicking on a water droplet will display all information available for that site. If the site was visited more than once, the user has the ability to scroll through all the visit information using arrows within the pop-up box.

A blue water droplet on the map indicates a location where algae was observed, and a sample was collected. Results from lab analysis are reported in the table below, and can be viewed by clicking on a blue water droplet on the map.

Who to Contact

The state’s bloom response team encourages residents to report algal blooms so that we can respond quickly and effectively.

  • Florida Department of Environmental Protection collects and analyzes algal bloom samples.
  • Florida Department of Health issues health advisories when toxin levels present a risk to human health.
  • Florida Fish and Wildlife Conservation Commission (FWC) responds to reported fish kills and collects algae samples at nearshore sites.
    • To report a fish kill, contact the Fish Kill Hotline at 800-636-0511.
    • To report any other wildlife injuries, call FWC’s Wildlife Alert at 1-888-404-3922.
  • County governments issue public beach closures. For more information, contact:

Health Effects

The World Health Organization considers levels under 10 micrograms/liter to represent a low-level risk for adverse health outcomes from short-term recreational exposures; however, certain sensitive populations (e.g., children, the elderly and immunocompromised populations) may still be at risk even at low concentrations and should avoid any exposure.

DOH takes the lead in determining if a HAB presents a risk to human health. DOH issues health advisories as they determine to be appropriate when toxicity levels are higher and may also post warning signs when blooms affect public beaches or other areas where there is the risk of human exposure. These actions are typically directed out of local county health departments, most often in consultation with staff from DOH’s staff from Public Health Toxicology Section. DOH also follows up on reports of pets that may have been exposed to a bloom, since these events may predict potential human health threats.
