How does Parklane Water Association compare with other water systems in Island County?
By EPA's size categories, Parklane Water Association is a very small system (500 people or fewer). Island County has 307 active public water systems. Its population served is about 62% below the county average of 335 people per system, and accounts for 0.1% of the 102,977 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 Parklane Water Association is well below that figure.
What does “community water system” mean?

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 Parklane Water Association?
EPA lists Parklane Water Association 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. 274 of the 307 active systems in Island County (89%) are also privately owned.
Does Parklane 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 September 2024. The violations listed here began between January 2005 and September 2024. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 9 as resolved and 3 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.
