:: Focus on Acid Rock Drainage

The May 2004 issue of Mining Environmental Management examines acid rock drainage (ARD), still referred to as acid mine drainage (AMD) by many. An overview is given by Terry Mudder (pp. 2), and the same author, with Gregory Olson discuss the chemical control of ARD (pps. 8-13). Two extensive reports on ARD can be downloaded from the website of the International Network for Acid Prevention.
