Abstract : This project addresses the need for refinement and demonstration of a new treatment process designed to restore water degraded by acid mine drainage (AMD). Processes resulting in acid deposition have had a significant negative effect on aquatic resources in North America, including the loss of important commercial and recreational fisheries. Direct effects of acidification on fish include acute mortality, reproductive failure, altered growth rates, and chronic impairment to body organs and tissues. Negative indirect effects of acidification include fish habitat degradation,increase in concentrations of soluble toxic metals, such as aluminum, and changes in predator-prey relationships. Within the coal deposit regions of Appalachia and the Ohio River Basin, AMD contributes significantly to acidification of surface waters.
