Each municipality is rated on its IRCA score for town water. IRCA runs from 0 (no risk) to 100. Up to 5 is treated here as low risk. From 5.1 to 14 is not officially fit to drink untreated. From 14.1 to 35 is high risk on this site, and above 35 is critical. Rural water is often worse and is shown separately when it was reported. Some departments are absent because town-by-town results were not available.
