Groundwater contaminated by hexavalent chromium [Cr(VI)] is a worldwide problem resulting from the widespread industrial use of chromium. Zerovalent iron (Fe 0) and Fe(II)-containing minerals have been found to be effective at removing dissolved Cr(VI) from water via reductive precipitation of trivalent chromium [Cr(III)] compounds.Permeable reactive barriers (PRBs) …
