MBMG Environmental Program

The MBMG Environmental Program undertakes site-specific investigations, many of which deal with environmental impacts from abandoned mining and milling operations. However, it also includes studies relating to other water-quality problems in groundwater systems (both inorganic and organic constituents). The program is currently involved with projects in five counties throughout Montana:


  1. Cascade (1 site);
  2. Jefferson (2 sites);
  3. Glacier–Toole (county wide);
  4. Silver Bow (3 sites); and
  5. Stillwater (1 site).

Program History

Projects undertaken are primarily funded though grants and agreements with Federal, State, and local agencies, i.e., U.S. Forest Service, MT Department of Environmental Quality, and MT Department of Justice, with funding occasionally from private parties. Over the past 35 plus years, many dozens of Montana Tech undergraduate and graduate students have been employed to work on the various projects. Many of these students have produced graduate thesis related to their work activities with MBMG’s Environmental Program.

Projects have ranged from studies relating to groundwater recharge, reclamation of dryland salinity problems throughout central Montana, hazard assessment of abandoned mine sites throughout Montana, identification of organic compounds in groundwater, impacts of smelter emissions on nearby areas, and long-term groundwater and surface-water monitoring associated with abandoned mine sites, including the filling of the Berkeley Pit and underground mines in Butte.



Martin Lorenzo (Environmental Engineering graduate student, near raft) and Dr. Bill Drury (Environmental Engineering) prepare to launch a raft for collecting water and sediment samples from a beaver pond. Thesis was funded as part of MBMG investigations related to Anaconda Smelter fallout in the Mill Creek Drainage, south of Anaconda, Montana.
