Cities ranked by the records
Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.
0of 5 cities above the 15 µg/L action level
Based on each system's 90th-percentile result. Lead from household plumbing isn't in this record.
Lead in Florida1city reports hardness · Cape Coral, 6 gpg
None above 7 gpg, the USGS threshold for hard water. An aesthetic measure with no federal health limit.
