Abstract
Acid mine drainage (AMD) is an extremely persistent form of water pollution and causes significant degradation of water quality in mining regions around the world. The United States has addressed this problem by strictly regulating the effluent waters from mining operations, by reclaiming abandoned mines, and by developing new techniques to improve the quality of mine water at active and abandoned mining operations. Active mining operations contribute to the cost of reclaiming abandoned mines through a special tax on each ton of coal mined, and in addition spend over $1 million a day to treat contaminated mine water from operations that are, or have been recently, active. As a result, the adverse effects of acidic mine water on the streams and rivers of the United States have been substantially reduced. The AMD that remains originates at long- abandoned mine sites. Recent research developments should help to further reduce the impact that this AMD has on the waterways of the United States.
