Stage of Clean-up: Construction Underway
Montana Conditions at proposal (December 30, 1982): The SILVER Bow Creek Site covers about 24 stream miles in SILVER Bow and Deer Lodge Counties, Montana. The creek, between where it meets COPPER Creek in Butte and Warm Springs Ponds northeast of Anaconda, has been contaminated with a variety of wastes received from industrial, agricultural, and municipal activities for over 100 years. Contaminants such as HEAVY METALS and phosphates have been detected in the creek, which is used for drinking, irrigation, and recreation. Status (September 8, 1983): The State is attempting to remove some of abandoned mine tailings from the banks of SILVER Bow Creek to reduce its contamination. Status (June 10, 1986): EPA has conducted a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site. Preliminary evaluation of data indicates that sources upstream of the existing site are contributing to contamination in the creek. More...
