Florida has 2,777 active transient non-community water systems, 53% 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 O'Leno State Park?
EPA lists O'Leno State Park as owned by a state 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. 3 of the 70 active systems in Columbia County (4.3%) are also owned by a state government.
Does O'Leno State Park have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in August 2012. The violations listed here began between October 2004 and August 2012. By type: 7 monitoring and reporting and 5 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (11 of them). EPA lists 10 as resolved and 2 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. 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.
