Short description: Passive in-situ groundwater remediation using permeable reactive barriers (PRBs) is a new technology. PRBs are subsurface constructions situated across the flow paths of contaminant plumes, which remove the contaminants from the flow by geochemical processes activated by the reactive material of the barrier filling. Suitable materials in PRBs include elemental iron, activated carbon, zeolites, iron oxides/oxyhydrates, phosphates, clay minerals, and others. The choice of reactive materials and retention mechanisms are dependent on the type of contamination to be treated by the barrier system. The paper gives a brief overview of the application of PRBs for groundwater remediation.
