        Environmental Impact of Acid Mine Drainage

        This video shows how acid mine drainage from an abandoned coal mine has affected Wildcat Branch in Daniel Boone National Forest. Because the creek has an acidic pH of 2.9, many local organisms cannot survive there. As the biologist in the video explains, macroinvertebrates (insects and other small invertebrates visible to the naked eye) and the larger animals that feed on them are almost entirely absent, and reproductive cycles have been completely disrupted. Non-point-source pollution from acid mine drainage has destroyed the stream's food web.
