The 142-acre Murray Smelter site is located in Murray City, Utah. This former mineral processing area was once the largest lead smelter in the country. Formerly owned by the American Smelting and Refining Company (ASARCO), the site included two smelters: the Germania Smelter and Refinery Works, which operated from 1872 to 1902, and the Murray Smelter, which operated from 1902 to 1949. In addition to lead, primary smelting byproducts included slag, arsenic and cadmium. Smelting activities and waste disposal practices contaminated soil, sediment and groundwater with heavy metals. Following cleanup, operation and maintenance activities are ongoing.
