Algal Bloom Response Summary:

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).

In response to reported Florida algal blooms, on July 7 and 8 DEP, FWC and South Florida Water Management District staff were deployed to survey and collect samples at various locations along the St. Lucie River and Estuary, the Caloosahatchee River and Estuary and nearshore marine locations. A total of seven samples were collected, which included the Cape Coral Yacht Club. The toxin level at the yacht club was extremely low and all other samples were non-detect for toxins. Additional surveillance and sampling of any observed blooms will be conducted in these areas later this week.

In response to reported Florida algal blooms during the week of July 4, DEP, South Florida Water Management District, FWC and Okeechobee Utility Authority staff were deployed to survey and collect samples at approximately 20 locations on Lake Okeechobee, the Caloosahatchee River, St. Lucie River, Ft. Pierce Inlet Beach, Blind Creek Park North, Jensen Beach, Bathtub Beach, Hobe Sound Beach and Coral Cove Beach.

The sampling results from the week of July 4 indicate an elevated toxin level at the St. Lucie Lock (C-44 at S80). While this lock, which is operated by the U.S. Army Corps of Engineers, is not located near shore, nor is it a recreational swimming area, DOH always encourages Floridians and visitors to exercise caution to minimize their risk. None of the other sampling results from the week of July 4 were above the World Health Organization’s short-term recreational exposure limit.

The Florida Department of Health at Martin County has issued an advisory encouraging Floridians and visitors to exercise caution to minimize their risk. If the water is discolored or a visible bloom is present, people are encouraged to stay out of the water, to keep pets and livestock out and to not use bloom water to irrigate lawns.

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.

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.”

Reporting

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