An innovative alternative to Acid Mine Drainage (AMD) control is the establishment of active Sulfate-Reducing Bacteria (SRB) communities within the pyritic material. This approach treats the AMD problem at its source converting sulfate/oxidized pyrite back into pyrite/metal sulfide precipitates within the mine waste material, thereby preventing AMD. laboratory and field experiments conducted by the Institute of Gas Technology, the U.S. Bureau of Mines, and the Illinois Abandoned Mined lands Reclamation Council are described that illustrate the essential features necessary for the establishment of SRB within pyritic mine waste, and practical concerns regarding the implementation of this AMD prevention approach are discussed.
