Verdict

On the 2 of 12 dimensions that carry measured values today, both sit in EPA Radon Zone 2; 2025 median air quality is Good in 84770 (AQI 44) and Moderate in 84101 (AQI 57). zipradar names no overall winner: the other 10 dimensions are not populated yet, and these two are county-level indicators rather than address-level readings.

Utah context

Radon Zone 1, wildfire, water-supply scarcity

Utah is uniformly Zone 1 radon. Wildfire risk concentrates in the Wasatch + southern UT. Great Salt Lake decline + Colorado River allotment uncertainty drive water-supply pressure on Salt Lake metro EPA SDWIS systems.
