How does Lakeside Park compare with other water systems in Ferry County?
By EPA's size categories, Lakeside Park is a very small system (500 people or fewer). Ferry County has 33 active public water systems. Its population served is roughly in line with the county average of 182 people per system, and accounts for 3% of the 5,998 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active community water system reports serving 6,703 people, so Lakeside Park 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. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.
Who owns and regulates Lakeside Park?
EPA lists Lakeside Park as privately owned. The WA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 24 of the 33 active systems in Ferry County (73%) are also privately owned.
Does Lakeside 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 July 2025. The violations listed here began between December 2006 and July 2025. By type: 6 monitoring and reporting, 5 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Combined Uranium (4 of them). EPA lists 6 as resolved, 5 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
