Lawsuit: EPA Must Protect Manatees From Water Pollution

Three conservation groups sued the U.S. Environmental Protection Agency today for failing to protect manatees and sea turtles from water pollution in Florida.

Over half of the more than 1,000 manatee deaths in Florida in 2021 were attributable to starvation. The mass die-off is being caused by pollution-fueled algal blooms that have killed thousands of acres of seagrass in the Indian River Lagoon, highlighting the inadequacy of the state's federally approved water-quality standards.

Earthjustice is representing the Center for Biological Diversity, Save the Manatee Club and Defenders of Wildlife. Today's lawsuit, filed in federal court in the Middle District of Florida, pushes the court to require the EPA to reinitiate consultation with the U.S. Fish and Wildlife Service and National Marine Fisheries Service under the Endangered Species Act to reassess its approval of Florida's water-quality standards for the Indian River Lagoon.

The Florida manatee is currently experiencing an officially declared unusual mortality event along Florida's east coast, which includes important manatee warm-water habitat like the Indian River Lagoon. The lagoon supports more species of plants and animals than any other estuary in North America.

"Manatees need clean water to live in -- it's that simple," said Earthjustice attorney Elizabeth Forsyth. "The pollution in the Indian River Lagoon is preventable. We're asking EPA to step in and ensure the protection of the Indian River Lagoon and the species that depend on it."

Unchecked pollution in the Indian River Lagoon -- stemming from wastewater-treatment discharges, leaking septic systems, fertilizer runoff and other sources -- fuels algal blooms that kill seagrass and prevent it from growing back. Nearly a decade ago, the EPA approved the state's water-quality criteria for nitrogen and phosphorous, concluding the standards would not "adversely affect" manatees. New information, including the mass die-off of manatees in the lagoon, calls this conclusion into question.

"Hundreds of manatees are dying in the Indian River Lagoon as the water quality plummets, and the EPA must confront the massive nutrient pollution behind this disaster," said Ragan Whitlock, an attorney at the Center for Biological Diversity. "The existing water-quality standards just aren't strong enough to preserve this important ecosystem and save these amazing animals."

Florida's 2021 manatee deaths were more than double the average annual death rate over the previous five years. The number of deaths represents 19% of the Atlantic population of Florida manatees and 12.5% of all manatees in Florida.

"Florida's beloved manatees will continue to suffer and die as long as EPA maintains inadequate water quality standards," said Jane Davenport, senior attorney at Defenders of Wildlife. "There simply is no more time for EPA to waste in reinitiating consultation."

State and federal agency staff continued to witness high levels of malnourished and starving manatees throughout the winter of 2021-22, implementing a first-of-its-kind supplemental feeding program. In recent weeks the surrounding water has warmed, causing the manatees to disperse, and the program has been suspended. Unfortunately many manatees continue to suffer the long-term health consequences of starvation.

"Although nothing we do will bring back those nearly 1,000 manatees that suffered and died from years of neglect despite repeated warnings, we insist that the EPA join forces with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service to ensure that improved water quality standards are expeditiously set and met to bring an end to this travesty." said Patrick Rose, an aquatic biologist and executive director of Save the Manatee Club, who has worked for over 45 years to help bring the species back from near extinction since it was first listed as endangered in 1967.

The U.S. Fish and Wildlife Service downlisted the manatee from endangered to threatened in 2017. Since then the species has suffered significant setbacks from habitat degradation, red tide, cold winters and now unprecedented mass starvation from the catastrophic seagrass die-off.
