The Village of Mount Prospect has been made aware of reports from residents observing a black, soot-like residue on the exterior of their homes and vehicles in the northern part of the Village.
Village staff have logged all reported concerns and have notified the Illinois Environmental Protection Agency (IEPA), the Cook County Department of Environment and Sustainability, and Chicago Executive Airport for further review and investigation. Staff have also learned that similar reports are being made in surrounding communities.

“The Village is working with our regional partners to identify the source of the residue,” said William Schroeder, Director of Building and Inspection Services. “We appreciate residents bringing this to our attention and encourage anyone who notices similar issues to report them so that we can continue to share accurate information with the investigating agencies.”

The Village will continue to monitor the situation closely and provide updates as new information becomes available. Residents with additional questions or observations are encouraged to contact the Building Division at building@mountprospect.org.
