Developments and improvements of remedial technologies are needed to effectively manage arsenic contamination in groundwater at hazardous waste sites.

In June 2005, a 9.1 m long, 14 m deep, and 1.8 to 2.4 m wide (in the direction of groundwater flow) pilot-scale permeable reactive barrier (PRB) was installed at a former lead smelting facility, located near Helena, Montana (USA).

The reactive barrier was designed to treat groundwater contaminated with moderately high concentrations of both As(III) and As(V).

The reactive barrier...
