BUTTE- Beginning this June, Montana Resources will begin pumping the contaminated water out of the Berkeley Pit, but project managers say they’re already successfully filtering heavy metals out of the pit water.

Montana Resources and Atlantic Richfield Company are four years ahead of the project’s 2023 deadline, when scientists estimate the Berkeley Pit will reach the “Critical Water Level” and pose a threat to both the community and the environment.

The complex pumping system filters out copper and the other toxic chemicals in the pit water through pipelines that travel from Montana Resources to Horseshoe Bend Water Treatment Plant, to the Polishing Plant, then finally discharging clean water into Silver Bow Creek.
