Coal Ash Contaminates Our Lives

What is coal ash?

Coal ash is what is left behind when power plants burn coal for energy; it is a toxic mix of carcinogens, neurotoxins, and other hazardous pollutants.

Stories From the Frontlines

‘Do Your Job, EPA’

By law, before government regulations are adopted or changed, agencies must ask the public — you — to weigh in. Here's what the EPA heard.

Cleaning Up Coal Ash For Good

How clean closure of coal ash impoundments provides jobs, economic benefits, and redevelopment opportunities for host communities.

Coal Ash Contaminates Our Water

For decades, utilities disposed of coal ash by dumping it in unlined ponds, landfills and mines where the toxic pollution leaks into groundwater. Industry’s own data indicate that across the country, 91% of coal plants are currently contaminating groundwater above federal safe drinking water standards.

101 Coal Plants With Toxic Sludge Threatening Our Drinking Water

New analysis reveals more than 100 power plants dumped coal ash into ponds that are dangerously close to or totally submerged in drinking water sources.

Coal Ash Contaminates Our Health

Coal ash contains hazardous pollutants including arsenic, chromium, lead, lithium, mercury, radium, selenium, and other heavy metals, which have been linked to cancer, heart and thyroid disease, reproductive failure, and neurological harm.

Damage to Aquatic Life from Coal Ash Disposal

The release of bioaccumulative toxic pollutants from coal ash has caused fish kills, deformities in fish and amphibians, and health hazards to people consuming contaminated fish.

Fighting Against Coal Ash

Coal ash remains one of our nation’s largest toxic industrial waste streams, U.S. coal plants continue to produce approximately 70 million tons of coal ash every year.

2015 EPA Coal Ash Rule & Legacy Sites

In 2015, EPA adopted its first-ever safeguards to protect people from toxic coal ash to settle a 2012 lawsuit brought by Earthjustice. But the Coal Combustion Residuals (CCR) rule failed to regulate approximately half of all coal ash in the U.S. — more than a billion tons — stored in legacy coal ash ponds and landfills.

At many of these legacy sites, EPA determined that coal ash has contaminated groundwater, but did not require monitoring, closure, or cleanup. The exempted coal ash ponds and landfills are sited disproportionately in low-income communities and communities of color.

In 2023, EPA agreed to revise the rule.

Where are Coal Ash Dump Sites?

Based on analysis of industry data, Earthjustice identified 573 landfills and ponds at 245 coal plants in 40 states that were excluded from EPA’s 2015 Coal Ash Rule.

Poisonous Coverup: Industry is Flouting the Coal Ash Rule

Nearly a decade after EPA established the first-ever protective requirements for coal ash disposal, progress to clean up contaminated groundwater and safely close dangerous coal ash ponds is dismal.

Cleaning Up Coal Ash For Good

As an increasing number of aging power plants across the United States cease operations, the companies that profited from burning coal for decades must not be allowed to walk away from dealing with the hundreds of coal ash dumps leaking toxic waste into groundwater.

Enforcement and strengthening of the coal ash rule will ensure that these toxic dumps do not present long-term threats or cause irreparable harm.

Hundreds of coal ash ponds must be closed over the next several years, and many plant owners are proposing inadequate and sometimes illegal and dangerous closures.
