Verdict

On the 2 of 12 dimensions that carry measured values today, both sit in EPA Radon Zone 3; neither water system reports a health-based violation in 3 years. 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.

Hawaii context

Tsunami, lava-zone, water-source isolation

Hawaii's federated data is unusual: FEMA tsunami evacuation zones are state-managed alongside NFHL flood maps; Big Island lava-flow zones (USGS) overlay FEMA hazard layers. Each island operates independent water utilities, so EPA SDWIS PWSIDs do not aggregate across the state.
