What is being done to manage the Berkeley Pit?
The Berkeley Pit, an open pit copper mine started in 1955 and abandoned in the early 1980’s, has been filling with water. The water is toxic due to extremely high concentrations of metals from the pit and the connected underground mine workings. Water levels continue to rise. The Horseshoe Bend Water Treatment Plant was constructed adjacent to the pit in order to eventually treat the contaminated water, preventing the water of the pit from infiltrating surrounding ground and surface water.
