Radon mitigation in Vermillion, SD became a priority for this homeowner after an at-home test measured 16 pCi/L—four times the EPA action level of 4 pCi/L. Because long-term radon exposure can increase lung cancer risk, and because an elevated result can raise questions during a future home sale, the homeowner contacted Blackburn Foundation Repair for a professional solution.
Why a 16 pCi/L Radon Reading Matters
Radon is a naturally occurring, invisible, odorless gas that can move from the soil into a home through cracks, joints, and other openings in the foundation. You cannot see or smell it, so testing is the only way to know the radon level inside a home.
The EPA recommends taking action when a home’s radon level is 4 pCi/L or higher. At 16 pCi/L, this Vermillion home’s initial reading was well above that benchmark. Addressing the issue supported two important goals: reducing the household’s potential long-term exposure and helping the homeowner prepare the property for resale with greater confidence.
A Radon Mitigation System Designed for the Home
Blackburn Foundation Repair installed a radon mitigation system tailored to the property. A typical active soil depressurization system uses sealed PVC piping and a continuously operating fan to create negative pressure beneath the slab. That pressure helps collect radon-containing soil gas before it enters the living space, then carries the gas through the piping to a safe outdoor discharge location.
For this installation, a visible section of the system’s sealed piping was routed through the garage. The garage route provides a practical path for the pipe while keeping the system organized and helping move collected soil gas away from the home. The piping shown is part of the mitigation route—not a pipe that releases radon into the garage.

Health Protection and Resale Peace of Mind
Taking action on an elevated radon result is an important home-health decision. It can also help a future real estate transaction go more smoothly by showing buyers that the homeowner identified the concern and had a professional mitigation system installed.
No post-installation reading is reported in this story. Radon levels can only be confirmed through follow-up testing after a system is installed, and continued periodic testing is a smart part of responsible homeownership.
