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. Accessibility features: Caption	6-12	Video
