Groundwater Cleanup

Scientists are developing different technologies for cleaning up pollutants in groundwater.

Figure 8.1 Contaminant remediation using permeable reactive barriers. The Permeable Reactive Barriers (PRBs), commonly called "iron walls," is another approach to remediate contaminated groundwater. In this process, macro-sized iron particles are placed into the ground forming a permeable iron barrier or wall that dissolves the pollutants in the groundwater. (Courtesy of Jeff Dixon.
