Superfund Site: MONTICELLO RADIOACTIVELY CONTAMINATED PROPERTIES
Superfund Site Profile
The Monticello Radioactively Contaminated Properties site consists of 424 private and commercial properties in and around the city of Monticello, Utah, covering approximately four square miles. Tailings were removed from the nearby Monticello Mill Tailings site, which is also on the Superfund National Priorities List. These tailings were used by various parties as fill for open lands; backfill around water, sewer, and electrical utilities; sub-base for driveways, sidewalks, and concrete slabs; backfill against basement foundations; and as sand mix in concrete, plaster and mortar.
