Superfund Site: SILVER BOW CREEK/BUTTE AREA
Superfund Site Profile
Many removal and cleanup actions have been completed to address immediate threats to human health and the environment in Butte. Cleanup, operation and maintenance, sampling, and monitoring actions are ongoing.
In May 2017, EPA and the Montana Department of Environment Quality published a final report that presents a summary and interpretation of surface water quality data collected at the Butte Priority Soils Operable Unit.
The Silver Bow Creek/Butte Area site is located in Butte, Montana and covers about 26 miles of stream and streamside habitat. Since the late 1800s, mining crews dumped mining wastes into on-site streams and wetlands near mining operations. These activities contaminated soil, groundwater and surface water with heavy metals.
