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 2 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.

Frequently asked
How does McMinn County tap water compare across cities?
PurityMap ranks 2 cities in McMinn County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record.

The highest published score is Athens's main water system: ATHENS UTILITIES BOARD · PWSID TN0000024 · Purity Score 99 (Excellent) · Confidence: moderate · Assessed at the water-system level. The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.
How many McMinn County cities had a PFAS sample above a 2024 EPA limit?
None of the 2 McMinn County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing. PFAS were detected below the limit in 1.
Is there lead in McMinn County tap water?
