Abstract

Evaluation of Passive Versus Active Abandoned Mine Drainage Treatment Systems

Terry Schmidt,  Skelly and Loy, Inc.

Watershed associations and government agencies are often faced with the prospect of long-term treatment of coal mine drainage in order to restore a watershed. In the last decade, passive treatment of coal mine drainage has become an acceptable and often preferred option. However, passive treatment is not applicable to all water treatment situations. The presentation will identify and compare factors relevant to treatment system selection such as capital cost, operation and maintenance cost, space requirements, availability of power, and other factors. Watershed associations and government agencies can use these tools to evaluate and compare their treatment options.
