Coal Slurry; Residue of Water and Chemicals After Coal is Washed

around Kayford Mountain, West Virginia, USA

Coal must be washed with water and processed with a variety of chemicals before it is used. This creates tremendous volumes of “slurry” which is stored in impoundments created by building an earthen dam across the end of a valley. On numerous occasions, impoundments have failed, releasing large quantities of the toxic mixture to devastate the valley below.
