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 ...
