A coal-fired power plant with ash ponds. Coal ash, also known as coal combustion residuals (CCRs), is the mineral residue that remains from burning coal. Exposure to coal ash and to the toxic substances it contains may pose a health risk to workers in coal-fired power plants and residents living near coal ash disposal sites.
Coal and coal waste products (including fly ash, bottom ash and boiler slag) release approximately 20 toxic-release chemicals, including arsenic, lead, mercury, nickel, vanadium, beryllium, cadmium, barium, chromium, copper, molybdenum, zinc, selenium and radium, which are dangerous if released into the environment. While these substances are ...
Photomicrograph made with a scanning electron microscope and back-scatter detector: cross section of fly ash particles. Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK)—plurale tantum: coal combustion residuals (CCRs)—is a coal combustion product that is composed of the particulates that are driven out of coal-fired boilers together with the flue gases.
Harmful byproduct of burning coal for power has been used as construction fill for decades, but no one kept track of where it went. EPA: Cancer risk from coal ash higher than previously revealed ...
One million gallons of coal ash-tainted water spilled at a Minnesota Power plant after a break in an underground plastic pipe, according to a company executive. The water, which was being siphoned ...
After a $1.2 billion cleanup that turned much of the 300-acre spill site into park land and put millions in investments back into Roane County, TVA no longer stores coal ash in wet ponds. Now, all ...
TVA had reportedly known about the dangers of using wet storage ponds for coal ash since a 1969 spill in Virginia in which coal ash seeped into the Clinch River and killed large numbers of fish. [15] TVA officials were also confirmed to have been aware of the toxicity of coal ash as early as 1981. [2]
Coal ash deposits on the Dan River shoreline, downstream from the spill. On February 2, 2014 a drainage pipe burst at a coal ash containment pond owned by Duke Energy in Eden, North Carolina, sending 39,000 tons of coal ash into the Dan River. In addition to the coal ash, 27 million gallons of wastewater from the plant was released into the ...
