How does Shady Oaks Subdivision compare with other water systems in Columbia County?
By EPA's size categories, Shady Oaks Subdivision is a very small system (500 people or fewer). Columbia County has 70 active public water systems. Its population served is about 34% below the county average of 404 people per system, and accounts for 0.9% of the 28,292 people reported by systems filed under the county.

Nationally, the average active community water system reports serving 6,703 people, so Shady Oaks 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 Shady Oaks Subdivision?
EPA lists Shady Oaks Subdivision 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. 61 of the 70 active systems in Columbia County (87%) are also privately owned.
Does Shady Oaks Subdivision have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between February 1997 and July 2025. By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 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.
