Waterways and beaches along Florida’s Atlantic coast have been taken over by thick, blue-green algae blooms, prompting Florida Gov. Rick Scott to declare local states of emergency in St. Lucie, Martin, Palm Beach and Lee counties.

Residents have described the foul-smelling algae as “guacamole-thick,” “god-awful” and “a festering infected creepy mess.” One resident has complained of health problems, telling Reuters, “It is affecting all of us as far as red eyes, runny nose and the ‘in the throat’ feeling.”

“It’s heartbreaking for all of us who live, work and play along the lagoon to see how the quality of the water has declined,” environmental non-profit Balance For Earth wrote on Facebook.

The source of the severe bloom is believed to stem from the polluted Lake Okeechobee, which has become a hotbed of finger-pointing.

ThinkProgress reported in February that local industries have long dumped an assortment of chemicals, fertilizers and cattle manure into the lake. David Guest, managing attorney of the Florida branch of the environmental law group Earthjustice, described the lake as a “toilet.”
