How does Liberty Park Water Association compare with other water systems in Orange County?
By EPA's size categories, Liberty Park Water Association is a very small system (500 people or fewer). Orange County has 46 active public water systems. Its population served is well below the county average of 69,606 people per system, and accounts for less than 0.1% of the 3,201,893 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active community water system reports serving 6,703 people, so Liberty Park Water Association is well below that figure.

Homes, apartments and mobile-home parks are served by these. California has 2,997 active community water systems, 40% of the state's 7,479 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.
Who owns and regulates Liberty Park Water Association?
EPA lists Liberty Park Water Association as privately owned. The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 12 of the 46 active systems in Orange County (26%) are also privately owned.
Does Liberty Park Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in February 2025. The violations listed here began between October 1980 and February 2025. By type: 4 monitoring and reporting, 2 contaminant level above the legal limit, 2 required treatment not met, 2 monitoring, 1 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 8 as resolved, 2 as unaddressed 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. 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.
