Since 1997, the Berkeley Pit Public Education Committee has given awards at annual Montana Tech Science & Engineering Fairs to students with projects that explore topics related to the Berkeley Pit. At the 2013 fair, five students received awards for Pit-related projects. Brian McGeehan from Butte Central received an award for his project, How Can We Clean Up the Berkeley […]

The water level at the Berkeley Pit has been recorded every month for more than 23 years. In addition to that monitoring, scientists at the Montana Bureau of Mines and Geology have been sampling and analyzing water from the Berkeley Pit twice a year for its chemical composition and physical properties. In the Berkeley Pit, samples are taken from anywhere […]

A performance test of the Horseshoe Bend plant was completed in November 2007, as mandated by the Record of Decision. Based on the performance review, water discharged from the plant meets all discharge standards for contaminants of concern set by the EPA. Additional adjustments still need to be made to address pH. In general, plant operations are going as expected. […]

Irrigating with mine water

Post-mining redevelopment efforts in Butte rely on the availability of water to irrigate vegetation on reclaimed and capped areas. Water recovered from the Belmont mine and other parts of the flooded underground mine workings is a possible source of irrigation water that would reduce the stress on the city water supply, leaving more water in the Big Hole River. Butte-Silver […]

Montana Tech geothermal project heats up

The 10,000 miles of underground tunnels beneath Butte have filled with water since the closure of the Berkeley Pit and, in 1982, the shut-off of groundwater pumps that had dewatered the underground in the past. These waters are typically regarded as a liability, but a new project at Montana Tech is viewing the watery mines of Butte as a potential […]
