The Environmental Protection Agency Thursday unveiled a final cleanup deal for Butte, marking a crucial turning point in the decades-long Superfund saga of Montana’s Mining City.

More than a century of copper mining in Butte helped electrify America and win both world wars. But, it also left behind a huge toxic mess that earned the city a Superfund site designation in the 1980s.

This week, the parties in charge of the Superfund cleanup of the Butte Hill and urban creek corridors agreed on a final cleanup deal, marking a turning point in the Mining City’s decades long Superfund saga.

This week, for the first time ever, once toxic water from the Berkeley Pit, the abandoned open pit copper mine in Butte, is being treated and released into the headwaters of the Clark Fork River.

For the first time ever, once-toxic water from the Berkeley Pit, Butte’s abandoned open pit copper mine, is being pumped, treated and discharged into Silver Bow Creek.

The Environmental Protection Agency is rolling out an updated plan to protect Anaconda’s creeks from copper smelter waste. But some locals this week said they’re worried the federal government may back away from Montana’s strict water quality standards for heavy metals.

Those awaiting the final Superfund cleanup deal, or consent decree, for the Butte Hill and urban Silver Bow Creek corridor are going to have to wait a little longer.

37 years ago, Atlantic Richfield abandoned an open pit copper mine in Butte and allowed it to flood with toxic mine water. Now, the company estimates they’re one month away from proving they’re in control of the Berkeley Pit. MTPR's Nora Saks got a sneak peek of their new water treatment facility and has more.

Wednesday night, Anacondans got a rare chance to speak directly about their experience with Superfund to the national office that investigates the Environmental Protection Agency. And most of what they had to say wasn’t complimentary.

Anaconda residents have attended countless Superfund meetings over the last 36 years. But unlike the others, this one wasn’t hosted by EPA.
