ACID MINE DRAINAGE

The generation of acid and subsequent leaching of heavy metals from waste rock material created primarily from mining operations. The leachate can contaminate surface and groundwater sources with acid and heavy metals. Work started with the US Bureau of Mines, and has been supported by the US Bureau of Land Management and Chevron Mining Inc. to design and operate humidity cell testing and to develop two mathematical models, one that describes humidity cell testing and another that simulates an actual waste rock pile at a mining site.

SELENIUM REMOVAL

A project, originally supported by Kennecott Utah Copper, to determine the optimum conditions in which a ferrous iron process, developed at the US Bureau of Reclamation, can effectively remove selenium from commercial waste streams to below detection limits.

BIOFUELS

Development of a new process for generating biofuels from synthesis gas using bacteria.

BIOREMEDIATION

The removal of heavy metals and other contaminants from wastewaters using immobilized biomass in a porous polymeric bead. Work initially started as a collaboration with former US Bureau of Mines. Removal of perclorates from waste water
