  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at proposal (October 15, l984): Sharon Steel Corp. owns a mill tailings site in Midvale, Salt Lake County, Utah. Midvale (population 10,000) is a part of the Salt Lake City metropolitan area (population 936,000). Metals were milled on the 260-acre site from about 1910 to 1971. Approximately 10 million tons of mill tailings containing high concentrations of LEAD, ARSENIC, CADMIUM, CHROMIUM, COPPER, and ZINC remain on the site. Sharon Steel purchased the site in 1979. This site was originally proposed for listing under the name "Sharon Steel Corp. (Midvale Smelter)." Issues of concern at the site include air contamination from wind-blown tailings, tailings washing into the Jordan River, and impacts on ground water. Ground water samples have shown contamination with ARSENIC and LEAD, according to analyses conducted by the State and Sharon Steel.  More...
