Radon Risk in Elk River & Sherburne County
Minnesota consistently ranks among the highest-radon states in the country. The Minnesota Department of Health estimates that approximately 2 in 5 Minnesota homes have radon levels above the EPA action level of 4 pCi/L — and Sherburne County is no exception.
Radon is a naturally occurring radioactive gas that seeps into homes from the soil and bedrock beneath your foundation. It's colorless, odorless, and tasteless — impossible to detect without testing. Long-term exposure is the second leading cause of lung cancer in the United States, responsible for about 21,000 deaths per year.
If you haven't tested your Elk River home, or if results came back above 4 pCi/L, the EPA recommends mitigation. Radon Stoppers can typically reduce levels below 2 pCi/L — often down to 1 pCi/L or less.

Elk River and Sherburne County: Where Glacial Soils Meet Elevated Radon
Elk River straddles the Sherburne and Wright County line, and both counties carry the same concern: radon. Sherburne County's geology includes glacial outwash and sandy soils over bedrock formations that can concentrate uranium decay products -- the source of radon gas. Homes in Elk River, whether on large acreage lots outside town or in established subdivisions closer to the river, are subject to radon infiltration regardless of foundation age or construction quality.
Elk River has seen significant residential growth since the 1990s, attracting buyers looking for more space while staying commutable to the Twin Cities. Many of those homes were built quickly and without robust radon-resistant features. A significant number of Elk River homeowners who test their homes for the first time discover levels above the EPA action level of 4 pCi/L -- consistent with the Minnesota Department of Health's statewide finding that roughly 2 in 5 MN homes have elevated radon.

Radon Mitigation FAQs for Elk River
Why is Elk River at risk for elevated radon?
Elk River sits in an area with glacial outwash soils that allow radon to migrate upward through the ground. Sherburne County's geology, combined with Minnesota's overall high radon profile, puts Elk River homes at measurable risk. The Minnesota Department of Health estimates about 2 in 5 MN homes exceed the EPA action level of 4 pCi/L. Testing is the only reliable way to confirm your home's level.
How quickly can Radon Stoppers schedule service in Elk River?
Radon Stoppers is based in Monticello, roughly 15 miles from central Elk River. We can typically schedule an assessment within a few days and complete the full installation in a single visit. We serve Elk River and surrounding Sherburne County communities including Big Lake, Zimmerman, and Princeton.
Do acreage homes in the Elk River area have more radon risk?
Homes on larger lots in rural Elk River and Sherburne County often sit closer to undisturbed soil with higher radon concentrations. Walk-out basements and slab-on-grade construction on sandy outwash soils can present specific challenges. Radon Stoppers assesses each property individually -- whether it's a newer construction on a rural lot or an older home in an established neighborhood.
