AB  - Permeable reactive barriers (PRBs) are receiving a great deal of attention as an 
      innovative, cost-effective technology for in situ clean up of groundwater 
      contamination. A wide variety of materials are being proposed for use in PRBs, 
      including zero-valent metals (e.g., iron metal), humic materials, oxides, 
      surfactant-modified zeolites (SMZs), and oxygen- and nitrate-releasing compounds. 
      PRB materials remove dissolved groundwater contaminants by immobilization within 
      the barrier or transformation to less harmful products. The primary removal 
      processes include: (1) sorption and precipitation, (2) chemical reaction, and (3) 
      biologically mediated reactions. This article presents an overview of the 
      mechanisms and factors controlling these individual processes and discusses the 
      implications for the feasibility and long-term effectiveness of PRB technologies.
