Cities ranked by the records

Showing 6 of 6 cities · scores are system-level, not tap tests

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.

Frequently asked

How does Hampden County tap water compare across cities?

PurityMap ranks 6 cities in Hampden 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 West Springfield's main water system: WEST SPRINGFIELD DPW WATER DIVISION · PWSID MA1325000 · Purity Score 98 (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 Hampden County cities had a PFAS sample above a 2024 EPA limit?

None of the 6 Hampden 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 Hampden County tap water?
