Radon in Edwardsville, IL is a concern for homeowners, especially those with basements or crawl spaces. The soil in this part of the state can release the colorless, odorless gas, which may accumulate indoors. Testing is the only way to know if levels are elevated, and if they are, mitigation systems can effectively reduce exposure. It's not something to panic about, but it's worth checking, particularly if you're buying a home or have never tested your current one.
