Implementation of Smart Bioremediation Technology to Reduce Sulfate Concentrations in Northeast Minnesota Watersheds

Minnesota faces the challenge of maintaining its existing iron ore and developing non-ferrous mining industries in northeastern Minnesota while protecting watersheds from elevated aqueous sulfate concentrations that could prove detrimental to animals and plants, especially wild rice. This research will create a commercial-ready remotely-operated modular bioremediation system to reduce sulfate concentrations in waters from past, present and potential future mining operations. Pilot scale designs of the technology have already shown high reductions of sulfate from legacy iron ore mine pit lake waters.
