Background
The former Velsicol Chemical Plant is located on 420 acres in east central Illinois, one mile north of the city of Marshall. The plant produced products derived from petroleum by-products and the pesticide, chlordane. EPA cancelled the use of chlordane and Velsicol stopped manufacturing operations at the Marshall plant in 1988. Ground water, sediment, and soil at the site are contaminated with volatile organic compounds and pesticides.
The cleanup plan selected included:
- Digging up contaminated sediments from a pond and soils from the plant production area
- Back filling areas with clean soil and vegetative covering
- Gathering removed material and treating through a chemical process
- Constructing ground water collection drains, disposing removed ground water to an on-site deep injection well or treating ground water before discharging off-site
- Monitoring ground water and surface cover conditions
- Operation and Maintenance of all cleanup systems
- Making sure land use and deed restrictions are enforced

Site Updates
May 2013 update
EPA is conducting a five-year review of the Velsicol Chemical (Illinois) site. The Superfund law requires regular checkups of sites that have been cleaned up – with waste managed on site – to make sure the cleanup continues to protect people and the environment.
EPA cleaned up ground water, sediment and soil contaminated with volatile organic compounds (VOCs), pesticides and cadmium. The cleanup included excavating contaminated sediment from an unnamed tributary and two ponds and digging up contaminated soil from the former production plant area and backfilling these areas with clean material. Excavated materials were consolidated, treated and capped. A ground water collection drain was constructed for collecting contaminated ground water, which is treated on-site and discharged to the sewer. Monitoring of ground water and the surface cover conditions and operation and maintenance of the cleanup systems are being performed. Land-use and deed restrictions are in place. The review should be completed this June.
