Here is what the EPA's own data shows about tap water in Cuba. According to EPA SDWIS data retrieved July 2026, Cuba is served by 3 active community water systems, together reported to serve about 2,052 people.
As of July 2026, EPA records show 206 violations across the community water system(s) serving Cuba, going back to the earliest EPA record. 62 of these are classified by the EPA as health-based (a contaminant recorded above the limit the EPA tracks); the rest are monitoring or reporting violations. Each is listed by system below, with its status.

What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
This page summarizes the EPA's own records and does not assess whether your water is safe to drink. For the most current details, you can verify every record directly with the EPA, and contact your water system with questions.
