Why are radon levels often high in Scott County homes?

Radon levels are frequently elevated in Scott County, including Savage, because of the region's underlying geology combined with how Minnesota homes are built. Radon forms from the natural decay of uranium in soil and bedrock, and the glacial deposits, river-valley sediments, and fractured bedrock common across the Minnesota River corridor release it readily. The gas migrates upward and enters homes through foundation cracks, sump pits, drain-tile openings, and gaps around plumbing penetrations. Minnesota's cold climate makes the problem worse: homes are sealed tight for energy efficiency and run with negative indoor air pressure during heating season, which actively draws soil gas inside, a phenomenon sometimes called the stack effect. That is why even brand-new Savage subdivision homes can test high. The Minnesota Department of Health reports that about 40 percent of homes statewide exceed the EPA action level. Lot position on or near the bluffs does not exempt a home; testing is the only reliable answer. We perform radon testing alongside the inspection and explain your results clearly.
