Clay County, Western Minnesota
Radon Mitigation in Moorhead, Minnesota
Moorhead is built on the bed of a vanished glacial lake, and that lakebed is the local radon engine. Clay County, named for exactly the soil in question, is rated Zone 1 on the EPA Map of Radon Zones, and the Minnesota Department of Health reports that 2 in 5 tested homes statewide have radon levels posing a significant health risk.
On the Minnesota side of the Fargo-Moorhead metro, radon work also comes with a licensing rule many residents do not know: it must be done by a contractor licensed by MDH. We connect Moorhead homeowners with exactly those independent, licensed professionals for free quotes.

Radon Levels Around Moorhead
Zone 1
the EPA radon zone for Clay County, predicting average indoor levels above 4 pCi/L
Zone 1 is the highest EPA radon potential category, and the statewide MDH numbers, 2 in 5 tested homes high and an average more than triple the national average, apply fully in the Red River Valley. Clay County maintains its own radon page for residents, and county-by-county test results live on the MDH data portal.
The Lake Agassiz Clay Plain
The DNR describes the Red River Valley as the deep-water basin of Glacial Lake Agassiz: a nearly featureless plain of poorly drained, silty and clayey soils. Those fine-grained sediments carry the uranium decay chain MDH identifies as the source of Minnesota radon, and when valley clays shrink and crack in dry spells, gas pathways open along foundations. Flat terrain, deep frost, and tight soils add up to soil gas that finds the path of least resistance, which is usually a basement.

Moorhead homes run from early-1900s blocks near the river and the colleges to postwar tracts and newer subdivisions on the south and east edges. Nearly everything has a full basement, and the Red River flood history makes sump baskets and drain tile standard equipment. For mitigation that is convenient: the sump is both a soil-gas entry route MDH lists and a ready-made suction point that gets sealed with an airtight lid. Homes permitted after June 1, 2009 include a passive rough-in under the state code.
Local Radon Contacts and Test Kits
Clay County maintains a radon program page for residents, and the MDH Local Radon Contacts directory lists current test kit sources and contacts across western Minnesota.

Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Moorhead, check their license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or laboratory analysis for compensation to be licensed by the Minnesota Department of Health, and every mitigation system installed under the law must carry an MDH system tag. A licensed professional expects the question. Three things to ask before you sign:
- Can I see your current MDH radon license, and is the company licensed too?
- Will the installed system carry the MDH system tag required under the licensing law?
- Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
Moorhead Radon Questions
Can a Fargo radon company work on my Moorhead house?
Only if it holds a Minnesota license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, covers radon work performed for compensation anywhere in Minnesota, regardless of where the company is based. Check any firm, Fargo-based or not, in the MDH license lookup before signing.
Does Red River Valley clay soil really drive radon into Moorhead homes?
The valley floor is the silty, clay-rich bed of Glacial Lake Agassiz per the DNR, Clay County is rated EPA Zone 1, and MDH ties radon to uranium decaying in rocks and soil. The combination makes elevated indoor readings common across the valley, and testing is the only way to know your own number.
My Moorhead basement has a sump pit for flooding. Is that a radon problem?
An open sump basket is one of the soil-gas entry routes MDH lists, and in the valley almost every home has one. Mitigation contractors seal it with an airtight, serviceable lid and often use the basket or drain tile loop as the suction point, without affecting the pump.
What does radon mitigation cost in Moorhead?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide. Valley homes with accessible sump baskets often make clean suction-point candidates. The contractor you are matched with quotes your house in writing, free, before any work.
