Coal slurry impoundment
A coal slurry impoundment consists of solid and liquid
wasteand is a by-productof the coal miningand preparation processes. It is a fine coal refuseand water.
Mining generates enormous amounts of solid waste in the form of rocks and dirt. This refuse is used to
damthe opening of a between adjacent mountains.
After the dam is built, the void behind it is typically filled with millions of gallons of waste slurry from a
coal preparation plant. This impounded liquid waste can sometimes total billions of gallons in a single facility.
disastersassociated with these slurry impoundments have called into question their safety. In 1972, a slurry impoundment outside of Logan County, West Virginiaburst, resulting in a rush of 130 million gallons of toxicwater (the Buffalo Creek Flood). Out of a population of 5,000 people, 125 people were killed, 1,121 were injured, and over 4,000 were left homeless. The flood caused 50 million dollars in damages. Despite evidence of negligence, the Pittston Company, which owned the compromised dam, called the event an " Act of God."
