Superfund Division

Superfund Designation in Butte

In 1983, Butte, Montana was declared a federal Superfund Site.  The boundary of Silver Bow Creek/Butte area site begins at the Continental Divide and extends along the flood plain of Silver Bow Creek for approximately 26 miles of stream and stream side habitat. Mine tailings deposits throughout the area contain elevated metals from a century of mining and smelting in Butte and Anaconda, Montana.

Since 1983, over 600 acres of land have been remediated and reclaimed. Butte-Silver Bow Superfund Division is responsible for the ongoing maintenance of remediated and reclaimed areas.  Sites throughout the Operable Unit are evaluated for protectiveness annually and corrective action is implemented where necessary.  In addition, Butte-Silver Bow inspects and maintains Superfund storm water structures to ensure sediments and debris do not enter the storm water collection system and negatively impact the health of Silver Bow Creek. 

The Residential Metals Abatement Program is designed to mitigate resident exposure to the potentially harmful effects of lead, arsenic, and mercury. The RMAP program samples residential soils, paint, attic and indoor dust and performs blood lead sampling to determine a property's need for abatement.  For more information on this program, please visit the Health Department's Environmental Health Program webpage. 

Environmental Restoration & Redevelopment 

In recent years, effort has been concentrated on the restoration of the Butte Hill including the planting native trees and flora, designating open spaces for historic interpretation and recreation, and better connecting the public to its transformed landscape. 

In April of 2015, Butte-Silver Bow appointed the Superfund Advisory and Redevelopment Trust Authority (SARTA) to advise Butte-Silver Bow staff on matters of Superfund policy and administers Redevelopment Trust Fund dollars.
