Highest and lowest Water Scores in Hialeah, Florida

10 ranked by Water Score from public records. A higher score means fewer findings.

Data updated October 24, 2026

How this ranking works

Water Scores run from 5 to 100, and a higher score means fewer findings in public records. Every row uses the same method, with no manual moves and no paid placement.

  • Only rows with both a PFAS result (EPA UCMR 5) and a lead 90th percentile are ranked. Equal scores share a rank.
  • The score subtracts points when a utility's UCMR 5 PFOA or PFOS results averaged above 4.0 ppt, the level EPA set in 2024, not yet enforceable.
  • A ZIP code served by more than one utility is scored on its main utility; the others are named in the row.

Not a test of your tap. Water Scores are educational estimates from public data, not medical advice.

ScoreYourWater also sells water treatment systems.

Questions people ask

Is Hialeah tap water safe?

Here is what the public records show for the water utilities in Hialeah: 10 ranked entries have Water Scores from 50 to 55. Scores use public records from 2015 to 2026. That isn't a clean bill of health or a health finding. EPA's national files don't hold sample results for most regulated contaminants. For health questions, ask your utility or your doctor.
