USA: Uranium mining in Black Hills
A planned uranium mine site in the southern Black Hills can impact four aquifers. Powertech, Inc. USA plans to begin uranium extraction in 2011 and operate for 15 years in the permit area of 10,580 acres located in Dewey and Burdock Counties, north of Edgemont, SD. PT plans to drill 4000-8000 wells to a depth of 400-800 feet underground to extract 1 million pounds uranium per year, initially using 4000 gallons of water per minute. As well as the four aquifers in this area, the site includes the surface water of Beaver Creek and Pass Creek, which empty into the Cheyenne River downstream from the mine site.
