How does Maple Haven compare with other water systems in Clallam County?
By EPA's size categories, Maple Haven is a very small system (500 people or fewer). Clallam County has 100 active public water systems. Its population served is well below the county average of 879 people per system, and accounts for less than 0.1% of the 87,933 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 Maple Haven 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 Maple Haven?
EPA lists Maple Haven 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. 75 of the 100 active systems in Clallam County (75%) are also privately owned.
Does Maple Haven have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2024. The violations listed here began between January 2020 and April 2024. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, p-Dichlorobenzene, Chlorobenzene and Benzene. EPA lists 11 as archived and 1 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.
