Radon Mitigation in Grand Rapids, MI

Radon Mitigation in Grand Rapids, Michigan

Grand Rapids and Kent County sit on glacial outwash and till deposits from the Lake Michigan lobe of the Laurentide ice sheet, overlying carbonate bedrock that produces consistent radon across west Michigan. Michigan averages 4.2 pCi/L statewide, and Grand Rapids-area homes in Ada, Cascade, Forest Hills, Lowell, and surrounding Kent County communities frequently test between 4 and 15 pCi/L. West Michigan's Zone 1 designation reflects the genuine risk from its glacial geology.

Why Grand Rapids Has Elevated Radon

West Michigan is EPA Radon Zone 1. Kent County's geology features deep glacial outwash — highly permeable sand and gravel deposits — overlying Devonian carbonate bedrock. These carbonates contain uranium-bearing minerals, and the permeable outwash above them acts as an efficient radon pathway into homes. The Grand River valley, which cuts through the metro, exposes carbonate formations throughout the area.

Ada Township and Cascade Township on the east side of the metro sit on higher ground with thinner topsoil and more direct bedrock exposure — these areas test highest in the county. Forest Hills and Lowell also test above the county average. Downtown Grand Rapids and west side neighborhoods sit on deeper outwash deposits and typically test lower.
