Radon in O'Fallon, MO is a serious concern because this area sits on glacial till and limestone, which can trap uranium and release radon gas into homes. Many basements around St. Charles County test high for it, and since you can't smell or see it, the only way to know your risk is to run a test kit. Local radon mitigation companies are familiar with regional construction styles, so getting a professional assessment is straightforward if levels are elevated.
