US Department of Energy

The Department of Energy says that the high levels of uranium at a contaminated site on Wind River Reservation might not flush out of the groundwater naturally in 100 years, like they previously thought.  

Tailings from a uranium mill that functioned at the Riverton Uranium Mill Tailings Radiation Control Act site in the 1960s left the area’s groundwater with high levels of uranium and the DOE took over management of the site in the late ‘80s.
