Background
The Eagle Zinc site is located in the city and township of Hillsboro, Illinois, Montgomery County. The 132-acre site is located in a commercial /industrial/residential area in northeast Hillsboro. The site extends from Smith road to the north of Middle Fork of Shoal Creek on the south. The site operated as a zinc smelter from 1912 to 2003. Other site operations included the production of sulfuric acid and zinc oxide.
Leftover material and contaminants from the manufacturing operations are concentrated in 15 piles, which are mainly located in the central and southern portions of the site. A large pond that formerly provided water for site operations is located in the southwest corner of the site. Buildings formerly used for manufacturing operation currently occupy 20 percent of the site. The site is currently zoned industrial by the city of Hillsboro and legal restrictions on the property limit future site use to industrial use. Local authorities have expressed interest in redeveloping the site.
