Superfund Site Profile

SITE BACKGROUND

The Sandoval Zinc Company site is located in Sandoval, Illinois. The Sandoval Zinc Company operated a smelter on site for 85 years. Zinc smelting is the process for converting zinc-bearing ores into pure zinc. The company closed down the smelter in 1985 and filed for bankruptcy. Air emissions from the plant included metals and wind-blown ash. Large amounts of smelting wastes were used in making secondary roads and for fill material on site. The company offered material not used by the plant to the public and the Village of Sandoval for use in surface roadways, driveways, sidewalks and parking lots. Following short-term cleanups to protect human health and the environment, site investigations are ongoing. They will inform development of the site’s long-term remedy.
