Florida Algal Bloom Response Summary

Sampling Schedule

“On July 21, DEP conducted surveillance and collected samples of observed Florida algal blooms in Palm Beach County near the G-538 where the L-8 canal meets L-8 Flow Equalization Basin, as well as on the Caloosahatchee from the mouth of the river near Little Shell Island to the Tamiami Trail Bridge.

Lee County also conducted surveillance and collected samples of observed Florida algal blooms near Alva Boat Ramp, Franklin Locks upstream and downstream, Davis Boat Ramp, North Shore Park and Midpoint Bridge Park.

On July 20, the Florida Fish and Wildlife Conservation Commission conducted sampling at Ft. Pierce Inlet Beach, Blind Creek Park North, Jensen Beach, Bathtub Beach, Hobe Sound Beach and Coral Cove Beach.

On July 19, the South Florida Water Management District surveyed and collected samples of any observed Florida algal blooms at the S80 St. Lucie Lock and Flying Cow Rd. Bridge just west of Wellington.

On July 18, the Florida Department of Environmental Protection surveyed the Caloosahatchee River downstream of the Midpoint Bridge, including the Cape Coral Yacht Community Park and Iona Cove near Shell Point. Along the St. Lucie, DEP staff surveyed downstream from Lock S80. Samples were collected where blooms were present, including near Shell Point Retirement Community, Cape Coral Yacht Club Community Park Boat Ramp and Channel Marker 76 in the Caloosahatchee River.

On July 18, the South Florida Water Management District surveyed and collected samples of any observed blooms on the Caloosahatchee and at Port Mayaca, including S77 Moore Haven, S78 Ortona, S79 Franklin Lock and S308C Port Mayaca.

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 July 18, DEP staff were deployed to survey and collect samples on the Caloosahatchee and St. Lucie rivers. A total of four samples were collected. All sample results were below the World Health Organization’s short-term recreational exposure limit, including the Cape Coral Yacht Club, which was non-detect for toxins.

In response to reported algal blooms during the week of July 11, DEP, South Florida Water Management District and FWC 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 22 samples were collected.

The sampling results from the week of July 11 indicate an elevated toxin level at Flying Cow Road Bridge and S-155 in Palm Beach County. While these areas are not located near shore, nor are they recreational swimming areas, DOH always encourages Floridians and visitors to exercise caution to minimize their risk. None of the other sampling results from the week of July 11 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 Florida algal blooms so that we can respond quickly and effectively.

  • To report a Florida algal bloom in Lake Okeechobee or the St. Lucie or Caloosahatchee rivers, call the toll-free hotline at 855-305-3903 or report online at www.reportalgalbloom.com.
  • To report human illness or for information on health advisories, contact your local county health department.
  • To report a fish kill, contact FWC’s Fish Kill Hotline at 800-636-0511.
