Excerpt from this story from Inside Climate News:

A task force appointed by Florida Gov. Ron DeSantis to address the state’s algal bloom crisis concluded in a recent report that “without hard work and careful planning” adverse human health impacts and widespread wildlife mortality would most likely “worsen” because of climate change and the state’s growing population.

The blooms are caused by high concentrations of a plant-like microscopic organism known as Karenia brevis fed by nutrients in runoff from stormwater, agricultural lands and wastewater treatment plants. A key stimulant is phosphorus from fertilizer used on farms and ranches in the Kissimmee River Basin, which forms the headwaters of the Everglades and drains into Lake Okeechobee, which in turn reaches the coasts through rivers and man-made canals.

The algal blooms, which at one point in 2018 covered 90 percent of the lake’s surface, can have devastating impacts on ecological resources and communities, causing respiratory and eye irritation in humans and “widespread reports of fish, sea turtle, marine mammal, and other wildlife mortalities,” according to the Florida Harmful Algal Bloom Task Force.

Released on Jan. 10, the task force’s report recommends more research to determine the causes of red tides, more investment in mitigation technologies and continued work under the Clean Waterways Act of 2020.

What the task force described as a “prolonged 2017-2019 red tide event” began with an algal bloom on Lake Okeechobee and resulted in “estimated total losses of nearly $1 billion in revenue and an additional loss of $178 million in tax revenue in 23 Gulf coast counties.”

But environmental advocates criticized the task force’s latest recommendations, arguing that the panel failed to hold the polluters accountable and ignored the most obvious solutions, which involve better enforcement of existing laws by the state regulators. The Clean Waterways Act of 2020, they have noted, doesn’t require agricultural interests to reduce phosphorus runoff and continues to rely on what is effectively a system of voluntary compliance.

“The task force recommends throwing taxpayer money at unproven mitigation technologies,” said Jaclyn Lopez, Florida director at the Center for Biological Diversity, adding: “If the state regulators instead just stopped pollution at the source by holding polluters accountable, Florida would have a much better chance at turning the corner on its water quality crisis.”
