The Everglades and Big Sugar
Tainted bass a warning for all of us
March 10, 1989
What a winter for the Everglades. First the sawgrass catches fire, and now the fish are contaminated.
Health agencies have warned anglers not to eat any largemouth bass or warmouth caught in Conservation Areas 2 and 3. They've also suggested reduced consumption of bass pulled out of the Loxahatchee National Wildlife Refuge.
The reason: Samples of these fish show high and potentially harmful levels of mercury.
Such a warning is unprecedented for any freshwater species in Florida. When bass (the state fish) are in jeopardy, it's a startling signal that something very bad is happening out in the black muck of the Glades.
The story goes way beyond the culinary concerns of weekend fishermen. What's happening—invisibly, bewilderingly—is the poisoning of the source of our water and of the food chain that it supports. Animals that ingest mercury don't necessarily die, but they sometimes stop reproducing.
The sprawl of the contamination is boggling. They're not talking about a backyard pond or a patch of marsh or even a whole creek. The danger zone encompasses more than 1,200 square miles of vital watershed.
Tainted bass have been found as far north as Loxahatchee and as far south as the L-67 canal in Dade. The fish, about 70 in all, were collected with electronic stunning gear. They weighed between 2 and 8 pounds each. Experts were shocked at the amounts of mercury discovered.
The government considers any level exceeding 0.5 parts per million to be cause for concern. Anything over 1.5 is unfit for human consumption.
No wonder health workers were alarmed, then, when one of the sample Everglades bass tested at 4.4 parts mercury per million. Some sites yielded fish with levels averaging 2.5.
Much has been made of these statistics because people want to know how much mercury is safe to eat. Fact: Bass aren't supposed to have heavy metals in their flesh.
In humans, mercury poisoning can damage the central nervous system.The most famous and tragic outbreak occurred in the 19505, when mercury-laden effluent from a factory contaminated the fish in Minamata Bay, Japan. Thousands of people who ate the fish suffered severe mercury poisoning that led to blindness, paralysis and birth defects. More than 300 died.
The Everglades scenario is not so extreme. The average person would have to eat a mess of tainted bass to be affected, but the health risk is larger for pregnant women and nursing mothers.
Actually, the edibility of these fish is the least of concerns. The more urgent riddle is where the pollution is coming from and what it portends for the ecology of South Florida.
"There is no theory at this point," says Frank Morello, a biologist with the Game and Fresh Water Fish Commission. "It's just a mystery."
The possibilities are far-ranging. Mercury can travel airborne from coal-burning power plants. It's also a common residue of agricultural fungicides, which have been known to be flushed into the Glades.
Over time mercury accumulates in living tissue, and the high levels found in the bass suggest a serious long-term pollution. Sediment samples might provide some clues, if not answers. The trick is tracing the source of this slop and identifying the offenders.
In a way, the invisible nature of the mercury threat makes it easy to underestimate. It's not like a red tide or a chemical spill. You won't see lots of bloated bass or dead panfish floating around the docks; in fact, you won't see much of anything.
A sudden fish kill looks more dramatic, but it tends to be brief and contained. The slow poisoning of an entire ecosystem is more sinister and potentially more catastrophic.
The hushed beauty of the Everglades is deceiving. It is so rich with life that we naturally assume all the life to be healthy.
For now, mercury and all, there are plenty of lunker largemouth bass to be caught. But the way it's going, someday we'll be fishing for them with magnets instead of worms.
News isn't so sweet for Big Sugar
March 5, 1990
The sugar industry, despoiler of the Everglades, got some not-so-sweet news last week.
Powerful federal agencies have come down strongly on the side of U.S. Attorney Dexter Lehtinen, who is suing to make Florida clean its water.
A report of the U.S. Department of Interior, U.S. Army Corps of Engineers and the Environmental Protection Agency says Everglades pollution is at "crisis proportions," and the state's plan to stop it is too weak.
The prime pollutants are phosphates, and the chief culprit is Big Sugar. Because cane companies donate lots of money to politicians, their disgraceful irrigation techniques have been overlooked for years.
Lehtinen ruined the party with his unprecedented lawsuit, which was filed 18 months ago. It charged the South Florida Water Management District with pumping filthy farm runoff into Everglades National Park. And it charged the state Department of Environmental Regulation with doing virtually nothing to stop it.
The message of the suit was so simple: Make the growers quit fouling our water. It hardly seemed like too much to ask.
But it was. The great state of Florida has spent more than $1 million in legal fees to fight the case. Makes you proud to be a taxpayer, doesn't it? The lawyers get rich while the water gets worse.
All sides agree that the public will be better served if an agreement can be reached out of court. As usual, politics is mucking up the priorities.
Gov. Martinez wants the lawsuit to disappear because it's politically embarrassing. The board of the water district (which Martinez loaded with farmers and developers) wants the lawsuit to go away because it could cost Big Sugar a fortune.
Florida had insisted it would come up with a comprehensive plan to save the Everglades, if only the feds would back off. Given the sorry history of water management, it was difficult to be bubbly with optimism.
Sure enough, the district's new Surface Water Improvement and Management plan was greeted by environmentalists with resounding derision. SWIM would give Big Sugar until the year 2002 to clean up its act, using 40,000 acres of public wetlands as filtering pools.
Water managers said they didn't know what SWIM would cost, or how much of the expense would be borne by agriculture. Big Sugar's response: We'll be happy to help clean up our slop if Uncle Sam pays every penny of the cost.
What a deal. It's like emptying a septic tank into your neighbor's bathtub, then demanding money before you'll mop it up—and finishing the job 12 years later.
The sugar growers' arrogance is well-founded. Thanks to the state, they get all the fresh water they want. Thanks to the feds, they can sell their crop at artificially inflated prices.
It isn't farming, it's glorified welfare. Naturally Big Sugar wants the public to pay for its pollution remedies—we've been paying, one way or another, for everything else.
State agencies always had the power to halt the polluting, but never had the political spine to do it. The staffs of the water districts are handcuffed because board members are political appointees who know more about irrigating campaign treasuries than vegetable fields.
The great thing about the U.S. attorney's lawsuit is that it forces the issue: Why should the Okeechobee growers be allowed to do what no other private industry can?
Knowing what we now do about the slow death of the Everglades, it's appalling that the sugar debate has lasted so long. The ultimate price of such cowardly politics could be a future of rationed, tainted drinking water for our kids.
We owe the Big Sugar companies zero; they owe us. They should filter the runoff on their own land, at their own expense, starting now.
