  • An Explanation of Acid Mine Drainage

    In a nutshell, acid mine drainage is a form of water pollution that happens when rain, runoff, or streams come in contact with rock that is rich in sulfur. As a result, the water becomes very acidic and damages downstream aquatic ecosystems. In some regions, it is the most common form of stream and river pollution.Sulfur-bearing rock, especially one type of mineral called pyrite, is routinely ...
