How does Flamingo compare with other water systems in Monroe County?
By EPA's size categories, Flamingo is a very small system (500 people or fewer). Monroe County has 4 active public water systems, and Flamingo is the 4th-largest of them by population served. Its population served is well below the county average of 7,531 people per system, and accounts for less than 0.1% of the 30,125 people reported by systems filed under the county. Across Florida, the 5,197 active systems average 4,345 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Flamingo is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Florida has 780 active non-transient non-community water systems, 15% of the state's 5,197 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 5 Florida systems (less than 0.1%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Flamingo?
EPA lists Flamingo as owned by the federal government. 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. 2 of the 4 active systems in Monroe County (50%) are also owned by the federal government.
Does Flamingo have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2025. The violations listed here began between April 2024 and April 2025. By type: 5 monitoring, 5 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 9 as resolved, 2 as unaddressed and 1 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.
