The 312-acre Eagle Zinc Superfund site is located in a mixed commercial/industrial and residential area on the northeast side of the City of Hillsboro in Montgomery County, Illinois. The site extends from Smith Road south to an unnamed tributary to the Middle Fork of Shoal Creek. Industrial Drive extends north and south along much of the site's eastern boundary. To the north are Smith Street, a small industrial facility called Hayes Abrasives, a golf course, and farm fields. Active industrial operations ceased at teh Eagle Zinc site in 2003.
Approximately 20 to 30 percent of the Eagle Zinc site is covered by a total of about 23 buildings. The site is zoned commercial/industrial and Hillsboro has indicated interest in acquiring the property for use as an industrial park.
EPA placed the Eagle Zinc site on the National Priorities List in 2007.
The Eagle Zinc site is being addressed by federal and State actions.
Threats and Contaminants
Soil and buildings at the Eagle Zinc site are contaminated with inorganic contaminants such as lead. Residue piles at the site may pose a leaching hazard to groundwater and ultimately to surface water drainage areas.
Humans could be exposed to site contaminants by dermal contact with soil and debris or by ingesting contaminated soil. Over the long term, exposure to thse contaminants could casue non-carinogenic health effects.
EPA has organized the Eagle Zinc site into two portions or operable units (OUs):
• Operable Unit 01: Building Demolition
• Operable Unit 02: Multi-media (Soil, Groundwater, Surface Water, and Residue Piles)
In May 2008, partner agency Illinois EPA had conducted a sampling event in and around the structures on the Eagle Zinc site. Results indicated high levels of lead contamination that could pose a health risk to anyone who came into contact with it. Also, the buildings were in dilapidated condition and at risk of collapse. In September 2009, EPA signed an Interim Record of Decision (ROD) that containing the selected cleanup remedy, which consists of razing the contaminated buildings, recycling as much of the debris as possible, and then managing the residual building materials on site under a soil cover. The 2009 ROD and supporting documents are available to the public for viewing at the Hillsboro Public Library.
In May 2012, EPA completed the remedial investigation (RI) and feasibility study (FS) reports. The RI report discussed the levels of contaminants found in site sediment, soil, surface water, and waste materials and presents the calculated potential human health and ecological risks posed by the contaminants. The FS report presents the various cleanup options that EPA evaluated to address the site risks. On September 6, 2012, EPA signed the final ROD for the Eagle Zinc site, selecting soil and sediment excavation remedies and groundwater cleanup actions.
In spring 2014, EPA completed the remedial design for the interim remedial action and in September 2014, EPA began planning the construction work necessary to implement the design. After the interim remedy is complete, EPA will complete the remedial design for the final remedy in preparation for its implementation.
EPA and partner agency Illinois EPA interact with the Hillsboro community in accordance with the site-specific Community Involvement Plan (CIP), which is available for view at the Hillsboro Public Library.
Federal, state, and local officials are regularly in contact with EPA and/or partner agency Illinois EPA concerning the progress of EPA cleanup work at the Eagle Zinc site.
Property ReuseHillsboro has indicated interest in acquiring the Eagle Zinc site property after all cleanups are completed so that it can be developed into an industrial park.
