That means addressing pollution at its source:
Addressing pollution at its source is something our water managers don’t want to do simply because they think it will cost too much. But not doing it will most certainly cost more in the long run, because sooner or later it will be done, like it or not. Meanwhile, we are taking new bounds down that road as we see more and more new science telling us of the dangerous consequences of allowing our polluters to continue.
The sources are well-identified but our state considers them too formidable to fight. Instead we spend more and more money on “studies” to find alternate ways to combat the symptoms.
Again, this report concentrates on areas far south of the Santa Fe River, but we have our very own polluters here and the algae as well.

Eve Samples and Howard L. Simon: Government should be required to warn Floridians when water is toxic
The scientists at Brain Chemistry Labs have sent the people of Florida another warning about the health threats posed by toxins in our waters — especially when red tide co-exists with polluted discharges from Lake Okeechobee.
Brain Chemistry Labs is a research institute in Jackson Hole, Wyoming, that has made groundbreaking contributions linking toxins in blue-green algae (particularly BMAA) to neuro-degenerative diseases, including ALS and Alzheimer’s disease. This work was dramatically chronicled in the documentary “Toxic Puzzle.” Their scientists spend considerable time in Florida — because they go where dangerous health threats exist.
The latest study, published in Neurotoxicity Research, documents the health threat from the perfect storm of 2018: cyanobacteria from nutrient-rich waters released from Lake Okeechobee down the Caloosahatchee River at the same time one of the worst outbreaks of red tide in the state’s history gathered along the west coast.
It’s scientifically improbable that red tide and blue-green algae would co-exist in the same waters. The former blooms in saltwater; the latter in freshwater. Yet the massive, unnatural discharges from Lake Okeechobee to the Caloosahatchee in 2018 pushed polluted freshwater to the coast, and toxins from the two blooms commingled.
The Brain Chemistry Labs research paper calls for more monitoring to understand the risk of exposure to co-occurring bevetoxins (in red tide) and microcystin and BMAA (in blue-green algae).
That brings us to the question of how to prevent toxic blooms from being intentionally discharged into our estuaries, where they could again mix with red tide.
The Army Corps of Engineers has the difficult assignment of maintaining water levels in Lake Okeechobee to ensure the Herbert Hoover Dike encircling the lake does not overflow. Water must be periodically released from Lake Okeechobee — but the schedule the Corps has used to store and release water has prioritized sugar farms south of the lake over the health and safety of residents who live near the estuaries where waters laden with toxic algae blooms flow.
Sending more lake water south during the dry season (when toxic algae blooms are less likely) would lower the lake levels before the rainy season, thereby reducing the risk of wet-season discharges to the estuaries (when toxic algae is more likely). But sugar companies have opposed lower lake levels in the winter months when they rely on Lake Okeechobee as a water source for crop irrigation.
The Corps must end its resistance to the mounting evidence of serious long-term health threats from toxic algae and do everything it can to avoid discharging water laced with harmful algal blooms to the populated communities along the Caloosahatchee and St. Lucie estuaries.
That means addressing pollution at its source: polluted waters flowing into Lake O from excess use of fertilizers, biosolids, leaky septic tanks, broken sewage treatment plants, stormwater and farm runoff and human waste from over-development.
It also means overhauling the way Lake Okeechobee is managed.
Until lake management and the pollution of our waters are effectively addressed — and by more than the half-measures trumpeted by the Legislature and the governor from the last legislative session — serious public-health threats will persist. Think of exposure to toxic waters like smoking: It doesn’t mean you will get lung cancer or seriously ill, but it certainly increases your risk….
