Washington, D.C. – American Rivers today named the Mobile River one of America’s Most Endangered Rivers® of 2022, highlighting the threat that coal ash pollution poses to clean water and public health.

The river is threatened by a leaking coal ash pond at Alabama Power’s Plant Barry, which contains more than 21 million tons of toxic coal ash. Alabama Power’s federal groundwater monitoring shows arsenic and other pollutants are already leaking from the ash pond. This pollution threatens the health of the Mobile-Tensaw Delta, Mobile Bay, the historic African-American community of Africatown, the city of Mobile and the Port of Mobile.

“America’s Most Endangered Rivers is an urgent call to action. Unless we speak up and demand action now, toxic, cancer-causing pollution will threaten communities along the Mobile River for decades to come,” said Ben Emanuel with American Rivers.

American Rivers and its partners called on the Alabama Department of Environmental Management (ADEM) and the U.S. Environmental Protection Agency (EPA) to enforce the removal and remediation of coal ash from the Plant Barry site and the banks of the Mobile River.

“Coal ash pollution is a serious public health crisis; it poisons the water that communities rely on. Plant Barry’s coal ash ticking time bomb is an example of what happens when regulatory agencies like ADEM focus on protecting industry instead of the communities they are supposed to serve,” said Jonathan Levenshus, Sierra Club Director of Federal Energy Campaigns. “Unfortunately, the coal ash at Plant Barry is only one of the sites in the United States that has millions and millions of tons of coal ash that are contaminating waterways. The EPA needs to step in and enforce federal regulations clearly stating that coal ash cannot be in contact with groundwater. Alabamians deserve protection from pollution, and if ADEM won’t step up to the plate, the EPA must act.” 

“Recent clarifications of the coal ash rule by EPA reinforce that Alabama Power’s current plan to cap 21 million tons of coal ash in a leaking unlined pit beside the Mobile River and Mobile-Tensaw Delta is not only foolhardy, it is illegal,” said Cade Kistler, Mobile Baykeeper. “Instead, Alabama Power should follow the lead of utilities in other southeastern states like the Carolinas, Virginia, Tennessee and Georgia where utilities are removing and/or recycling 250 million tons of coal ash. If our neighbors around the southeast can find a way to clean out coal ash pits to protect public health, the environment and the economy, Alabama can too. Now EPA and ADEM need to require Alabama Power to comply with the law and protect Mobile River and Mobile Bay by requiring coal ash removal at Plant Barry.”

Coal ash is the concentrated by-product of burning coal and contains contaminants such as radium, mercury, cadmium, arsenic, selenium and other carcinogens. For decades, Alabama Power’s Plant Barry has dumped 21 million tons of toxic coal ash into a 597-acre unlined pit only supported by earthen berms— allowing heavy metals and other toxins to contaminate groundwater and migrate into the Mobile River watershed. Plant Barry is surrounded on three sides by the Mobile River and sits in a floodplain of the river next to the Mobile-Tensaw River Delta, a hotspot for diverse plants, fish, birds and wildlife. Federal law now bans coal ash ponds located in these types of locations.

The annual America’s Most Endangered Rivers report is a list of rivers at a crossroads, where key decisions in the coming months will determine the rivers’ fates. Over the years, the report has helped spur many successes including the removal of outdated dams, the protection of rivers with Wild and Scenic designations and the prevention of harmful development and pollution.

The Rivers of Mobile Bay were previously included on this list in 2017. Also included on this year’s list is the Coosa River, due to the threat of pollution from industrial poultry farms. Other rivers in the region listed as most endangered in recent years include the South River and Turkey Creek (2021), Big Sunflower River (2020 and 2018), Okefenokee Swamp and St. Marys River (2020), and Appalachicola, Chattahoochee, and Flint rivers (2016).

American Rivers reviews nominations for America’s Most Endangered Rivers from local groups and individuals across the country, and selects rivers based on three criteria: 1) the river’s significance to people and wildlife, 2) the magnitude of the threat to the river and communities, especially in light of climate change and environmental justice, 3) a decision in the next 12 months that the public can influence.
