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 1 city 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 Anchorage Municipality tap water compare across cities?

The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.
How many Anchorage Municipality cities have PFAS above the federal limit?
1 city of 1 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Anchorage (PFOA 9.1 ng/L). PFAS were detected at any level in 1.
