Radon Test kits for non-Pitkin County Residents

Understanding Your Test Results

If your first radon test result is at or above the Environmental Protection Agency's (EPA) action level of 4 picocuries of radon per liter of air (pCi/L), then your next step is to retest: 

  • For results between 4 and 8 pCi/L, retest with a long term test kit.
  • For results above 8 pCi/L, retest in the same location with another short term test kit or kits. 
  • The City of Aspen has both short and long term radon test kits available to Aspen residents.
  • Over 1/2 of the homes tested in Aspen have levels in excess of the EPA recommended action level of 4 pCi/L.
  • High levels of radon (4 pCi/L or above) can be reduced through mitigation.

Radon Mitigation

If your test results are greater than 4 pCi/L, the EPA recommends mitigation.

  • Lowering high radon levels requires technical knowledge and special skills.
  • The City recommends that you use a certified radon mitigation contractor to ensure that the the correct system is installed for your building.
  • Mitigation costs can vary depending on the construction and type of home but generally costs range from approximately $1,500 to $2,500 for a medium size home. 
  • The City can provide assistance for Aspen residents to ensure that successful mitigation is done.
  • A list of local certified radon mitigators is provided for your reference though the City does not specifically endorse individual companies.
