Sub-surface mining frequently goes below the water table so water must be constantly pumped from the mine. Acid mine drainage results from the outflow of water from metal mines, coal mines, or other areas in which the ground has been disturbed. Metal salts, such as Fe +2, are oxidized upon contact with air to more highly acidic aquo species. Sulfur containing molecules are air oxidized to sulfuric acid.
