In Situ Sulfate Mediated Metal Remediation (i-SMMR) for the Treatment of Mine Impacted Groundwater
« All Publications

Groundwater impacts at mining sites are often comingled mixtures of sulfate, associated with the sulfuric acid leach solutions commonly used in mineral extraction, as well as various metals associated with the ore body or host rock being mined.

The focus of the research presentation is the development of cost effective and reliable processes for biologically reducing sulfate, yielding biological and abiotic chemical processes that result in the precipitation or geological sequestration of the metal-based contaminants present in the groundwater at mining sites. This presentation describes the development and microcosm testing of SiREM's MB-1® sulfate reduction consortium, grown in water from a metal impacted mine site located in Chile. This research is ongoing and is the basis of new in-situ passive approaches and bioremediation products for remediating metal-based groundwater contamination at mining sites.
