Case Description

The 446-acre Midvale Slag Superfund Site is located 12 miles south of Salt Lake City in Midvale City, with a small portion extending into Murray City. The site is a former smelting facility on the Jordan River. Five separate smelters were located on or near the site from 1871 to 1958. An adjacent mill continued operating until 1971. The smelters processed ores from Bingham Canyon and other mines. Investigations at the site showed groundwater and soils are contaminated with heavy metals.
