Florida Algal Bloom Response Summary
Sampling Schedule
“On Aug. 23, DEP surveyed the St. Lucie River, including areas around Lighthouse Pointe, Leighton Park and Roosevelt Bridge and collected samples if algal blooms were present.
The South Florida Water Management District surveyed the St. Lucie Lock S-80 and collected samples if algal blooms were present.
On Aug. 22-24, DEP will be conducting routine water-quality sampling along the Caloosahatchee River between Highway 41 and Shell Point at various locations and will collect samples if algal blooms are present.
On Aug. 22, the South Florida Water Management District surveyed the South Fork of the St. Lucie River and Estuary and collected samples if algal blooms were 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).
On August 16-17, DEP and FWC staff were deployed to survey and collect samples on the St. Lucie river and estuary and nearshore marine locations. A total of 9 samples were collected.All sample results were non-detect for toxins.
Since May 13, 2016, when the South Florida Water Management District (SFWMD) first observed an algal bloom on Lake Okeechobee during their routine sampling, DEP and the SFWMD have regularly responded to and sampled observed and reported algal blooms on Lake Okeechobee, in the St. Lucie River and Estuary and the Caloosahatchee River and Estuary.

Previous Sampling Results
Health Effects
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 Florida Algal 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 Aquatic Toxins Program. 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 also follows up on reports of pets that may have been exposed to a bloom, since these events may predict potential human health threats.”
