- Kerr-McGee Kress Creek/West Branch DuPage River Site
- Kerr-McGee Sewage Treatment Plant Site
- Kerr-McGee Residential Areas Superfund Site
- Kerr-McGee Reed-Keppler Park Superfund Site
There are four Kerr-McGee Superfund sites in the West Chicago, IL, area that were contaminated by radioactive thorium waste material. The waste was generated by a processing facility (now closed and owned by the Kerr-McGee Chemical Corporation) that operated in West Chicago between 1932 and 1973.
Sand-like waste materials known as mill tailings were stored at the facility. The mill tailings were available as free fill material from the 1930s through the 1950s and were used throughout the West Chicago area for landscaping projects and to fill low-lying areas. It was later determined that the radioactive material was potentially hazardous.
Wastes from the Kerr-McGee facility also entered Kress Creek through a storm sewer, contaminating sediments (river mud) in the creek and the West Branch DuPage River. (more...)

Kerr McGee Residential Properties
In January 2009, Tronox (formerly Kerr-McGee) filed for Chapter 11 bankruptcy. As a result of the bankruptcy settlement, the West Chicago Environmental Response Trust was set up to complete the cleanup and monitoring for the four West Chicago Kerr-McGee Superfund sites. As of April 2014, approximately 111,000 cubic yards of contaminated soils have been removed from more than 676 properties. Only one known property requiring cleanup remains and it is scheduled to be completed by July 2014. EPA routinely receives inquiries from general public in regards to the status of specific properties. In some cases EPA receives new information and determines additional sampling efforts are warranted. If any contamination is found above the cleanup standard, the property will be cleaned up by the Trust.
Kerr McGee Site (Kress Creek/West Branch of DuPage River)
The cleanup work at the Kress Creek site was conducted by Kerr-McGee, Tronox and the West Chicago Environmental Response Trust, along with their contractors, under the oversight of EPA, the State of Illinois, and the local communities. After the bankruptcy settlement, the cleanup of Reach 8A was initiated in July 2011 and was completed in early November 2011. The Bower Elementary School area in Reach 8A, Reach 8B and the Route 59 overpass over Kress Creek, the last of the KC/WBDR areas requiring cleanup, were all completed in the summer and fall of 2012. Maintenance and Monitoring of site restoration will continue for three more years, and then the Kress Creek site will be eligible for deletion from the NPL in 2016, provided that DOE Title X funding is received by the West Chicago trust.
Kerr McGee Site (Sewage Treatment Plant)
In January 2009, Tronox (formerly Kerr-McGee) filed for Chapter 11 bankruptcy. As a result of the bankruptcy settlement, a Trust was set up to complete the cleanup and monitoring for the four West Chicago Kerr-McGee Superfund sites. The Trust has been conducting maintenance and monitoring activities for the STP site since February 14, 2011. On August 11, 2011, a final Certification of Completion inspection was conducted to determine whether the STP site was complete and the maintenance and monitoring requirements had been successfully achieved. A punchlist of final items to be completed was generated, and these actions were accomplished in the spring of 2012. A Certification of Completion was then issued by EPA in September 2012, and a Final Closeout Report was completed for the site. On February 20, 2013 EPA published its Notice of Intent to Delete the Kerr-McGee Sewage Treatment Plant from the NPL. That deletion became final on April 21, 2013.
Kerr McGee Site (Reed-Keppler Park)
As of February 2010, the Kerr-McGee Reed-Keppler Park site was delisted from the National Priorities List. As specified in the September 2002 ROD, U.S. EPA was required to conduct a five-year review of conditions at the site to determine if the remedy selected in the ROD continued to be protective. A five-year review report was completed on August 13, 2007, and it is available in the site information repository. Now that the site has been cleaned up to the point where there are no residual contaminants remaining onsite that would prevent unrestricted use of the property, no more five-year reviews will be required for the Reed-Keppler Park site.
