Chromite ore processing residue (COPR), a waste product from chromium extraction, is highly alkaline and is toxic due to the soluble Cr(VI) it contains. Unregulated dumping during the previous century led to many sites being contaminated with this waste. As Cr(VI) migrates in groundwater flows, reduction to less toxic and insoluble Cr(III) seems a prudent remediation strategy. Zero valent iron permeable reactive barriers (ZVIPRBs) and biobarriers are both capable of in-situ reduction reactions and were thus investigated for their suitability to treat COPR impacted sites. Reduction of Cr(VI) by ZVI was possible at pH 12 however the rate was slow and unsustained. Amending pH resulted in increased reaction rates only in the acidic range (
