| Short description: |
In June 2005, a pilot-scale PRB containing granular iron was installed at a
former metal smelting facility near Helena, MT, to treat ground
water contaminated with concentrations (>25 mg/L) of arsenite
and arsenate. The barrier is 9.1 m long, 14 m deep, and 1.8 to
2.4 m wide (in the direction of ground-water flow). Within the
PRB, As concentrations are 2 to <0.01 mg/L. After 2 years of
operation, significant decreases in As concentrations are
evident. This report covers site characterization, remedial
design and implementation, and monitoring results for this
pilot-scale
