Utah Indoor Air Quality Guide
Salt Lake City's winter inversions trap pollutants for 2-4 weeks at a time
Zone 1 — Highest potential (predicted average > 4 pCi/L)
Radon Levels in Utah
Average Radon Level
6.7 pCi/L
EPA Zone
Zone 1
Utah is entirely Zone 1. The state's uranium-rich geology produces very high radon. Salt Lake Valley and Utah County consistently test above 4 pCi/L.
⚠️ Testing strongly recommended
Utah is Zone 1 — the highest risk category. Test every home. If levels are 4 pCi/L or above, install a mitigation system immediately.
Top Indoor Air Hazards in Utah
Radon Gas
CRITICALRadon is the #2 cause of lung cancer after smoking. It seeps from soil into basements and crawl spaces. You cannot see, smell, or taste it. The only way to know is to test.
Poor Ventilation (Stale Air)
MODERATEModern energy-efficient homes trap pollutants indoors. Without adequate ventilation, CO2, VOCs, and airborne pathogens accumulate to levels 2-5x higher than outdoors. This is called sick building syndrome.
Volatile Organic Compounds (VOCs)
HIGH RISKVOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Utah Climate & Air Quality Factors
Winter temperature inversions in Salt Lake Valley trap pollutants for weeks. Wildfire smoke from surrounding mountains is recurring. Dry climate reduces mold but new construction boom means VOC off-gassing in thousands of homes.
