  • Site Description
    Stage of Clean-up: Construction Underway

    ASARCO, Inc.'s Globe Plant covers approximately 92 acres at 495 East 51st Avenue, Denver, Colorado, near a neighborhood commonly known as Globeville. The site is in an industrial, commercial, and residential area of Denver and Adams Counties, on the western edge of the South Platte River channel and approximately 2.7 miles upstream of where the river meets Clear Creek. With the exception of the southeast section, the majority of the site is on a terrace that rises from 30 to 60 feet above the South Platte River floodplain. The Globe Plant began operating in 1886, producing gold, SILVER, COPPER, and LEAD. In 1901, American Smelting and Refining Co. (later renamed ASARCO, Inc.) purchased the site and converted it to a LEAD smelter. In 1921, LEAD smelting was replaced by ARSENIC trioxide production, which lasted for about 5 years, when the plant changed to CADMIUM production.  More...
