Frequently Asked Questions
People have many questions about Superfund — especially in a place with as much history and ongoing work as Butte.
This page provides clear, plain-language answers to common questions, with links to more detailed information if you want it.
Health & Safety
Yes. Butte's public drinking water is tested frequently and meets or exceeds all standards for drinking, cooking, and bathing.
Blood lead testing is encouraged for young children and is available at no cost through Superfund-related programs.

The Berkeley Pit & Mine Flooding

No. Drinking water sources are separate from the Berkeley Pit and are treated and tested.
Cleanup Process
The site is very large and complex. Cleanup happens in stages to ensure long-term protection. Each area moves through investigation, design, construction, and monitoring at its own pace.
An Operable Unit is a way to organize cleanup work by area or problem. It helps break a massive site into manageable pieces.
Responsible parties, primarily Atlantic Richfield, fund cleanup under EPA oversight.
Residential Cleanup
The Residential Metals Abatement Program (RMAP) provides free soil and attic testing and cleanup for eligible properties.
Testing and cleanup are designed to reduce risk and protect health, not penalize homeowners. The program is voluntary and confidential.
Recreation & Amenities
Yes. Recreation areas are designed and monitored to be safe for public use.
Some areas require continued management or monitoring to ensure long-term protection. Restrictions are targeted and communicated clearly.
