About the water column
The drinking-water percentage is state-level EPA ECHO context, so cities in the same state share that value. It is not a substitute for identifying the community water system that serves a specific address.
| State rank | City | Score | AQI now | Water systems without current health violation | Moisture pressure | Housing pre-1980 |
|---|---|---|---|---|---|---|
| #1 | Cheyenne, WY | 69.1 | 20 | 93.9% | 29.5 | 56.8% |
