Acid Mine Drainage and Precipitates

In 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.

Tunneling for Water: Geology and the Ohio River Tunnel Project

This video explains the importance of the Ohio River as a source of drinking water, its geologic origin, the rock strata exposed when Louisville Water Company dug a tunnel beside the river to access the water, and the meaning of the terms “aquifer” and “filtration."

Environmental Impact of Acid Mine Drainage

This 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.

The Geology of Coal

In 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.
