Water Quality Snapshot: MIAMI INTL AIRPORT

MIAMI INTL AIRPORT is a local-owned non-transient non-community water system that delivers drinking water to 25,000 residents in MIAMI, Florida (Miami-Dade County) through 8 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 43 total violations for this system , of which 6 (14%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 31 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 12 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 8 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.012 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Florida, EPA tracks 5,093 public water systems serving 22,381,282 people, with 184,355 cumulative violations and 24,266 health-based violations on record. About 93% of systems in the state carry at least one violation, and state-wide the average per system is 36.2 violations. MIAMI INTL AIRPORT's 43 violations sit above the Florida average. Statewide, 218 of 402 UCMR5-tested systems have reported PFAS detections (54.2%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
