An ash pond, also called a coal ash basin or surface impoundment, [1] is an engineered structure used at coal-fired power stations for the disposal of two types of coal combustion products: bottom ash and fly ash. The pond is used as a landfill to prevent the release of ash into the atmosphere.

2022年11月3日 · For decades, utilities have disposed of coal ash dangerously, dumping it in unlined ponds and landfills where the toxins leak into groundwater. According to industry’s own data, 94% of the coal ash ponds in the United States are unlined.

2024年8月23日 · Hundreds of coal ash pits and ponds sit near the banks of American waterways, threatening toxic spills that can cause long-term damage to the environment and public health. When coal is burned at any of America’s more than 200 coal-fired power plants, it leaves behind waste called coal combustion residuals, commonly referred to as ash.

2021年12月8日 · On Sunday, CNN published “Gambling ‘America’s Amazon,’” an investigation on a toxic coal ash pond in southern Alabama that experts say threatens one of the nation’s most pristine wetlands....

The report "Cleaning Up Coal Ash For Good" provides an analysis of closure and cleanup of coal ash ponds located at three coal-fired power plants in the U.S. Economists and environmental engineers compared the benefits, cost, and direct job creation of thoroughly removing the toxic pollution versus leaving the ash in place with a cap to cover it.

Coal ash is the toxic byproduct of coal-burning power plants. Power plants typically mix the ash with water and dump it in massive “ponds” or pits nearby. Toxic pollutants commonly found in coal ash include heavy metals such as arsenic, mercury, selenium, chromium, and lead, which are hazardous to human health, wildlife, and waterways.

An ash pond is an engineered structure for the disposal of bottom ash and fly ash. The wet disposal of ash into ash ponds is the most common ash disposal method, but other methods include dry disposal in landfills.

Coal ash pits vary widely, based on whether waste is stored in ponds (wet impoundments) or landfills (dry impoundments) as well as on their size and the level of hazard they present to human life. Coal ash pits often reside adjacent to the …

Ashtracker provides public access to industry-reported data from state and company records about groundwater contamination at coal ash dumps. Coal ash, a toxic waste generated by coal-fired power plants, is one of the largest industrial waste streams in the United States.
