Contamination of soil with arsenic (As) is a global environmental concern because As is toxic and carcinogenic. Ochre, a waste generated from mine water processing, has great potential for the remediation of As contaminated soils due to its high iron (Fe) oxyhydroxides content. Iron oxyhydroxides have large reactive surface areas for As adsorption. This research investigated the potential of ochre to adsorb As in solution and in contaminated soils and also assessed the possibility of using ochre to eliminate As exposure transport pathways (leaching to groundwater, plant uptake and soil ingestion).
