Naturita Processing Site

The Naturita processing site is a former uranium- and vanadium-ore-processing facility. Before 1942, the mill processed only vanadium ore; in 1942, operations shifted to recovery of uranium for the Manhattan Project. After the war, the facility operated a uranium upgrader from 1961 to 1963. Beginning in 1993, the U.S. Department of Energy removed 800,000 cubic yards of contaminated materials and soil from the site—including a pile of radioactive tailings that covered 24 acres of the site—and stored them within a disposal site located approximately 10 miles northwest. More than 11 acres of contaminated downgradient property and 1 acre of contaminated soil remain intact on this site.
