Florida Faces 3 Toxic Crises Triggered by Flooding

Ah, Florida—home to famous natural landscapes and amazing wildlife, but also to more than 20 million people and billion-dollar industries. Decades of booming development in Florida—all of it built in the path of Atlantic hurricanes—have brought to a head some toxic problems the state still struggles to solve. Every major flooding event, like the one following this year's Hurricane Irma, leaches toxic waste into people's homes and drinking water.

Florida is particularly vulnerable to storm surges and flooding from hurricanes like Irma. Scroll down to explore the natural disaster risks facing Florida and increasing its residents' toxic risks:


Threat #1: Superfund Sites

The U.S. Environmental Protection Agency's (EPA's) "Superfund" program oversees the cleanup of hazardous waste sites. Ahead of Hurricane Irma, the EPA worked to secure about 80 sites ranked at the highest priority for cleanup from Miami to North Carolina—but Florida alone contains more than 50 Superfund sites at this priority level, with approximately 500 hazardous waste sites in total. Superfund sites in Florida have been linked to increased cancer risk, and experts worry that these sites are vulnerable to flooding and spreading toxic pollution.

Threat #2: Radioactive Waste

Florida is a unique host to two phenomena: phosphate mining, which produces radioactive waste, and sinkholes. Much of the state's land is vulnerable to giving way under the weight of soaking water—in fact, Hurricane Irma brought an increase in sinkhole activity to at least eight communities. When sinkholes form below stores of phosphate mining wastewater, that radioactive material empties into the Floridan aquifer.

Threat #3: Livestock Sewage

Overflowing raw sewage—84 million gallons of it—flooded homes and claimed life and limb in Florida following Hurricane Irma.

And that's just sewage from cities and other communities. While human sewage is only a problem if sanitation facilities fail, livestock sewage remains unregulated and vulnerable to flooding. Florida produces millions of tons of livestock manure every year, which is either stored or use to irrigate fields in its raw, untreated form.

Irma will not be the last time these problems emerge. Florida faces a potent mix of threats every time torrential rain or storm surges bathe the state in its own toxic environmental footprint. Experts worry that current and proposed regulations for Superfund cleanups, the phosphate industry and factory farming are all seriously flawed, especially in the face of climate change and warming oceans, which could make the next storms that Florida encounters even more powerful—and more toxic.

Although natural gas produces fewer greenhouse gas emissions and other pollutants than coal or oil, it is a major contributor to climate change, an urgent global problem. Skitterphoto / PIxabay

Natural gas is a versatile fossil fuel that accounts for about a third of U.S. energy use. Although it produces fewer greenhouse gas emissions and other pollutants than coal or oil, natural gas is a major contributor to climate change, an urgent global problem. Reducing emissions from the natural gas system is especially challenging because natural gas is used roughly equally for electricity, heating, and industrial applications.

The U.S. Environmental Protection Agency (EPA) recently issued a list of 431 products that are effective at killing viruses when they are on surfaces. Now, a good year for Lysol manufacturer Reckitt Benckiser just got better when the EPA said that two Lysol products are among the products that can kill the novel coronavirus that causes COVID-19.

For all its posturing on climate change, the Democratic Party has long been weak on the actual policies we need to save us from extinction. President Barack Obama promised his presidency would mark "the moment when the rise of the oceans began to slow," and then embraced natural gas, a major driver of global temperature rise, as a "bridge fuel." Climate legislation passed in the House in 2009 would have allowed industries to buy credits to pollute, a practice known to concentrate toxic air in black and brown neighborhoods while doing little to cut emissions.
