Green Rust (GR) is an important tool in environmental remediation efforts to clean up groundwater impacted sites. Green rusts, mixed FeII/FeIII hydroxide minerals present in many anaerobic environments, have been shown to reduce a number of organic and inorganic contaminants.  FeII can reduce a range of organic and inorganic contaminants, and FeII is one of the most abundant reductants typically present in aquatic and terrestrial environments under suboxic and anoxic conditions.  GR, which is much less stable than the usual brown rust and is formed only under anaerobic conditions, plays an important role in the transport and reduction of many contaminants in suboxic soils and aquifers.  For more information on how GR can be applied at your site, please contact us.
