How does Olsen Apartments compare with other water systems in Pasco County?
By EPA's size categories, Olsen Apartments is a very small system (500 people or fewer). Pasco County has 211 active public water systems. Its population served is well below the county average of 1,960 people per system, and accounts for less than 0.1% of the 413,624 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 Olsen Apartments 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 means the system draws its water from wells or springs fed by underground aquifers. 4,996 Florida systems (96%) list groundwater as their primary source.
Who owns and regulates Olsen Apartments?
EPA lists Olsen Apartments as privately owned. 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. 180 of the 211 active systems in Pasco County (85%) are also privately owned.
Does Olsen Apartments have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between January 2025 and January 2026. By type: 5 monitoring, 5 monitoring and reporting, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 10 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
