Detoxification and Neutralization of Acid-producing Mine Waste

Acid generation from sulfidic mine tailings is a world-wide environmental problem affecting thousands of miles of stream, and in some cases, these streams are entirely devoid of fish. Research performed by KC Harvey scientists developed the scientific basis for permanent treatment of acid-producing mine waste through soil amendment followed by native plant revegetation. Remediation of acidic mine waste by soil amendment has been selected by EPA and State regulators for thousands of acres at Superfund sites in the western U.S. These techniques have been implemented over a period of several decades in watersheds impaired by mine waste resulting in water quality improvements.
