Sterigenics Information

At the end of August 2018, DuPage County, Willowbrook and surrounding communities were made aware of air sampling completed by the Agency for Toxic Substances and Disease Registry (ATSDR) around Sterigenics facility located in Willowbrook  due to its emission of ethylene oxide (EtO) into the atmosphere. ATSDR completed modeling based on the concentrations of EtO which concluded an increase in cancer risk may exist in the area due to exposure to the chemical. 

Below are documents and links with information about County activities as well documents and links to resources about EtO.  The Village of Willowbrook has also provided information on their website as well. Questions can be emailed to the U.S. EPA using the following - EtO@epa.gov.
