Superfund Site: MATTHIESSEN AND HEGELER ZINC COMPANY, LA SALLE, IL

Superfund Site Profile

The 160-acre Matthiessen and Hegeler Zinc Co. site is located in the city of La Salle in La Salle County, Illinois. A primary zinc smelting and rolling facility operated on site from 1858 to 1978. Former smelting and rolling processes produced pollution that remains on site. Environmental concerns include a 6-acre slag waste pile containing metals such as cadium, copper, chromium, lead, nickel and zinc. Runoff from the pile washes directly into the river and sediment samples from the river bottom indicate elevated levels of these metals. Following immediate actions to protect human health and the environment, site investigations and cleanup planning are ongoing.
