Showing 2 of 2 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.

Questions

Frequently asked

How does Saginaw County tap water compare across cities?

PurityMap ranks 2 cities in Saginaw County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities. The highest published score is Bridgeport's main water system: BRIDGEPORT TOWNSHIP · PWSID MI0000840 · 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 Saginaw County cities had a PFAS sample above a 2024 EPA limit?

None of the 2 Saginaw 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 Saginaw County tap water?

Utilities report lead as a 90th-percentile result from home taps. 2 of 2 Saginaw County cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
