DEPOT ST & MARQUETTE ST

The DePue/New Jersey Zinc/Mobil Chemical Superfund Site is located in the Village of DePue, Bureau County, Illinois, and consists of approximately 950 acres. According to the 2010 Census, the Village of DePue's population is 1,838. The primary zinc smelting facility on the site began operations in 1903 on 175 acres of farmland, but over the years expanded to more than 860 acres as additional plants were added. The original plant produced slab zinc, used in the automobile and appliances industries, and sulfuric acid. Zinc dust was also produced and used as an additive to produce corrosive-resistant paints. In 1967, in response to the increase in the demand for phosphate fertilizer, DePue/New Jersey Zinc constructed a diammonium phosphate (DAP) fertilizer plant. Mobil Chemical leased the DAP and sulfuric acid plants from New Jersey Zinc in 1972 and later purchased the plant in 1975. Mobil ceased manufacturing operations at the plant in August 1987 and the plants were demolished in April 1991. Two preliminary site assessments were completed in 1980 and 1983, followed by site inspections in 1984 and 1987. The Illinois Environmental Protection Agency (IEPA) conducted an expanded site inspection in March 1993 to gather additional soil, sediment, wastewater, and surface water samples. Based on those evaluations and sampling results, IEPA signed an Interim Consent Order with a group of Potentially Responsible Parties (PRPs) known as the DePue Group on November 6, 1995, to perform various investigations and cleanup actions at the site. The DePue Group, which represents former owners and/or operators of the site, consists of ExxonMobil and CBS Corporation (formerly Viacom).
