The Air Force is offering free indoor air testing to residents and businesses that are over areas of groundwater contamination from Hill Air Force Base.

Potentially harmful chemical vapors from the groundwater could be entering homes or workplaces. Having a test done is the only way to ensure your indoor air is safe.

A letter with details about the testing was mailed to affected areas in September.

If you received a letter, testing is needed. If your home has been tested previously and you received the letter mailing, additional testing is needed. If you did not receive a letter, your home or business does not require testing and is not in the affected area.

All testing is free and requires placement of a pencil-size device in the home for 26 days. Any mitigation to stop vapors from entering homes or other buildings, if needed, will also be free. Testing will run from October 2021 to March 2022.

For more information, including COVID precautions that will be taken during sampling and maps showing areas eligible for testing, go to: www.hill.af.mil/IAP or call 801-775-3651/3652.
