How does Fern Terrace Subdivision compare with other water systems in Lake County?
By EPA's size categories, Fern Terrace Subdivision is a very small system (500 people or fewer). Lake County has 275 active public water systems. Its population served is well below the county average of 1,569 people per system, and accounts for less than 0.1% of the 431,494 people reported by systems filed under the county. Across Florida, the 5,197 active systems average 4,345 people each. Nationally, the average active community water system reports serving 6,703 people, so Fern Terrace Subdivision is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Florida has 1,640 active community water systems, 32% 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 Fern Terrace Subdivision?
EPA lists Fern Terrace Subdivision as under public/private ownership. 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. 36 of the 275 active systems in Lake County (13%) are also under public/private ownership.
Does Fern Terrace Subdivision have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in May 2025. The violations listed here began between October 1984 and May 2025. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 9 as archived and 3 as resolved. 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. 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.
