The site is a 160-acre former zinc smelting and rolling facility. It was in operations from 1858 to 1978. The site is located on the east side of LaSalle, Illinois. It is bordered by the Little Vermilion River on the east, with residential properties surrounding the remainder of the area. The former smelting and rolling processes produced pollution that remains on the site. Environmentral concerns include a 6-acre slag waste pile containing metals such as cadium, copper, chronium, 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.
