Results of Mine Drainage Remediation

In this video, a biologist visits Lower Rock Creek in Pulaski County, Kentucky to show how acid mine drainage remediation has increased the stream’s pH from acidic levels almost to 7, which is neutral. Many fish species such as minnows, trout, and bass have returned to Rock Creek.

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. Macroinvertebrates and the larger animals that feed on them are almost entirely absent, and reproductive cycles have been completely disrupted.

Acid Mine Drainage Remediation

In this video, an environmental technologist visits an abandoned coal mine in Kentucky to talk about how a remediation system (a series of settling ponds and treatment cells) is neutralizing the acid drainage from the mine and preventing damage to a creek downstream.
