Acid Mine Drainage and PrecipitatesIn this video, environmental scientists measure the pH of water to detect acid mine drainage from an abandoned coal mine and then demonstrate how metals present in acid drainage fall out of solution as precipitates when a basic substance is added to the water.

Controlling Water Run-off
This video shows how the environmentally friendly design of the Visitor Center at Bernheim Arboretum and Research Forest near Louisville slows down water run-off and helps to control non-point-source water pollution, conserve water, and prevent soil erosion

Environmental Impact of Acid Mine DrainageThis video shows how acid mine drainage from an abandoned coal mine has affected Wildcat Branch in Kentucky's Daniel Boone National Forest. Because the creek has a very acidic pH of 2.9, most organisms cannot survive there, and Wildcat Branch is essentially dead. Accessibility features: Caption |

The Geology of CoalIn this video, a geologist describes how coal, a sedimentary rock, was formed when organic materials piled up in swamps millions of years ago. Over time, heat and pressure transformed the buried materials into forms of coal that cause acid mine drainage when exposed to oxygen. Accessibility features: Caption |

High-Sulfur Coal and Acidic WaterIn this video, a geologist measures the pH of water after high-sulfur coal from a Kentucky coal mine has been added to it. This test demonstrates that the sulfate salts found on the coal’s surface cause the water to become much more acidic. Accessibility features: Caption |

Results of Acid Mine Drainage RemediationIn this video, a biologist visits Rock Creek in Pulaski County, Kentucky to show how acid mine drainage remediation has increased the stream’s pH from acidic levels to almost neutral. Although the ecosystem has not been completely restored, many species have returned to Rock Creek. Accessibility features: Caption |
