Alabama Power recently released predictions on what would happen if coal ash dams were fail at their power plants. Coal ash is the waste left over from burning coal. It is mixed with water to form a liquid
slurry which is then pumped into holding pits. Environmentalists suggest that lined land-fills would prevent the waste from seeping into groundwater. The cost of such a change would differ from plant to plant but would likely be significant. Nelson Brooke is the Black Warrior Riverkeeper. He explained the worst case scenario.
