Radon Mitigation in Le Mars, IA
Le Mars is the county seat of Plymouth County, northeast of Sioux City. Plymouth County is one of Iowa's 99 counties that the EPA places in Zone 1, the highest predicted radon potential.
That designation reflects geology and measurement data across the county, not a verdict on any one home. Homes with basements, crawl spaces and slab floors can all have elevated radon. If you have not tested, a short-term test is the usual first step. If you are buying or selling in Le Mars, see our home sale testing page.
If Your Result Is 4 pCi/L or Higher
A result at or above 4 pCi/L is the level at which the EPA and the Iowa Department of Public Health recommend fixing the home. A mitigation system usually includes a suction point in the soil under the house, a vent pipe and a fan.
A credentialed professional should design and install it, and you should retest afterward to confirm the level has dropped. See our mitigation page for what the job involves, and the cost factors guide for what changes the scope.
