Impact/Purpose:
The purpose of this on-going research is to evaluate a remediation technology that can be applied to treat groundwater contaminated with arsenic. This research highlights field-based testing that has applications at a wide range of sites where arsenic treatment is necessary.
Description:
The U.S. EPA Office of Research and Development’s National Risk Management Research Laboratory (NRMRL) is conducting long-term monitoring of a granular iron permeable reactive barrier (PRB) for remediation of ground water contaminated with arsenic from a former lead smelting facility in Montana. Results from the six-year study show that the PRB has successfully removed high-levels of arsenic from ground water. Studies have included geochemical and hydraulic evaluations of PRB performance, including a flux-based understanding for establishing system design and tracking contaminant removal.
