Superfund Site: MONTICELLO MILL TAILINGS (USDOE), MONTICELLO, UT
Superfund Site Profile
The Monticello Mill Tailings (USDOE) site is located in Monticello, Utah. A vanadium mill operated on the property from 1942 until 1960. The mill produced uranium and vanadium for the U.S. nuclear weapons program. Milling activities generated thousands of cubic yards of ore tailings containing trace amounts of uranium. Milling activities and waste disposal practices contaminated soil, surface water and groundwater with heavy metals and radioactive constituents. Following cleanup, operation and maintenance activities are ongoing.
