Understanding and Responding to Hazardous Substances at Mine Sites in the Western United States

This volume documents interesting approaches, techniques, and practical scientific considerations associated with mine site remediation. It also highlights how various federal, state, and local agencies and organizations are trying to bring the best science possible to bear on this serious problem. Some chapters focus on specific methods for characterization, particular contaminant issues, and impacts from the release of hazardous substances from mine and mill sites. Others describe successful response actions, technologies, or practical approaches for addressing contaminant releases to the environment.

Abstract
Acidic metal-contaminated drainages are a critical problem facing many areas of the world. Acid rock drainage results when metal sulfide minerals, particularly pyrite, are oxidized by exposure to oxygen and water. The deleterious effects of these drainages on receiving streams are well known. To address this problem, efforts are being made to use biological processes as an innovative, cost-effective means for treating acidic metal-contaminated drainage. Biological sulfate reduction (BSR) technology can be adapted to diverse site conditions and water chemistry. The Lilly mine near the community of Elliston, Montana, illustrates some of the specific conditions that can challenge effective application of BSR technology.
