What does “community water system” mean?

Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 87 Florida systems (1.7%) list purchased groundwater as their primary source.
Who owns and regulates Hialeah Gardens?

The FL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 29 of the 172 active systems in Miami-Dade County (17%) are also owned by a local government.
Does Hialeah Gardens have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in March 2026. The violations listed here began between July 2004 and March 2026. By type: 5 contaminant level above the legal limit, 2 public notice, recordkeeping or other, 2 monitoring, 2 monitoring and reporting and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 6 as resolved, 3 as unaddressed and 3 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
