City and Health Department Urge Air Monitoring for Ethylene Oxide in Lake County

US EPA established page for Lake Co emissions concerns

The Lake County Health Department, in concert with the City of Waukegan and Village of Gurnee, continues to work with local, state and federal officials to address concerns of ethylene oxide emissions. On February 28, 2019, Health Department Executive Director Mark Pfister met with Illinois Environmental Protection Agency (IEPA) Director John Kim, Illinois Senator Melinda Bush, Gurnee Mayor Kristina Kovarik, and Waukegan Mayor Sam Cunningham to discuss options for ambient air monitoring in Lake County. 

“Ambient air monitoring is the logical next step in this developing situation. This testing would help us determine the levels of ethylene oxide exposure occurring in our communities,” said Executive Director Mark Pfister. “Together with Gurnee and Waukegan, we continue to urge our state and federal officials to take this step. In the meantime, we are exploring independent air monitoring as an option to assure the protection of our residents’ health.” 

The U.S. Environmental Protection Agency published a Lake County-specific web page on November 21, 2018. Residents seeking information about ethylene oxide in Lake County can find the latest updates at Questions and concerns can be sent via email to the U.S. EPA at
