Mining for uranium in Colorado started in the late-nineteenth century with the search for radium. Uravan started as a Standard Chemical Company mining camp named after the company chairman's son, Joe Junior. From 1914-1923, miners at the Joe Junior Camp mined carnotite. Carnotite was a source of radium, although it required 300 tons to create a gram of radium.

Uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. These tailings pose serious environmental and health risks in the form of Randon emission, windblown dust dispersal and leaching of contaminants including heavy metals and arsenic into the water.
