  Acid Mine Drainage Ground Truth Trekking

  There are three basic ways to limit acid mine drainage; prevent sulfuric acid from forming, neutralize the acid after it forms, or collect runoff/seepage to contain the acid. To stop the formation of sulfuric acid, the waste rock and tailings from a mine must be prevented from coming in contact with oxygen.
