Coal mining. Mining operations can negatively impact water supplies, often with longlasting effects. The fundamental issue involves contamination of nearby rivers, lakes, and aquifers by what comes out of a coal mine—usually highly acidic water containing heavy metals like arsenic, copper, and lead. The process is known as acid mine happens when certain substances (typically ...

Coal impacts: water pollution. When you burn charcoal in your grill at home, ash is leftover. The same is true for coalfired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.
