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 | Hartford, CT | 46.1 | 19 | 73.7% | 55.5 | 80.1% |
