Verdict

On the 3 of 12 dimensions that carry measured values today, both sit in EPA Radon Zone 2; 2025 median air quality is Moderate in both (AQI 73 vs 54); neither water system reports a health-based violation in 3 years. zipradar names no overall winner: the other 9 dimensions are not populated yet, and these three are county-level indicators rather than address-level readings.

Arizona context

Radon, wildfire-WUI, water rights

Arizona has Zone 1 radon risk across most of its area per EPA's 1993 map. FEMA NFHL coverage is dense in flood-prone Maricopa + Pima counties; wildfire risk concentrates in Yavapai + Coconino + Cochise. Water-rights and utility-source diversity (CAP allotments vs. local groundwater) varies significantly between metros.
