Radon Testing & Mitigation Across El Paso County
El Paso County is classified by the EPA as Radon Zone 1, the highest of its three risk tiers, meaning the predicted average indoor radon screening level for the county is above 4.0 pCi/L. The county covers everything from 5,500-foot valley floors in Fountain to 7,500-foot ridgelines on the Palmer Divide, and the radon picture changes with the ground underneath.
Why radon behaves the way it does in El Paso County
The ground underneath
Three different geological settings sit inside one county line. The western edge is Pikes Peak granite — coarse, uranium-bearing, and highly fractured. The centre and north sit on Dawson Arkose, a gravelly sandstone weathered directly out of that granite. The eastern plains are covered in alluvium and windblown deposits over the same underlying formations. All three can deliver radon into a building; they just do it through different soil permeability, which is why system design changes from one side of the county to the other.
The housing here
Foundation types across the county span practically every option in Colorado: full basements in the cities, walkout and garden-level basements on the Palmer Divide's slopes, crawl spaces in the older mountain towns, slab-on-grade in newer southern tract builds, and dirt-floor cellars in the historic districts. Each needs a different mitigation approach — sub-slab depressurization, sub-membrane depressurization for crawl spaces, or a combined system where a house has more than one foundation type.
What we see locally
Rural parts of the county — Peyton, Calhan, Black Forest, eastern Falcon — are on private wells. Radon can enter a home through well water as well as through soil gas, and it is released into the air when water is agitated by showers, dishwashers and washing machines. If you are on a well and your air test comes back elevated, water is worth ruling in or out.
