How does Forest Haven Subdivision compare with other water systems in Clackamas County?
By EPA's size categories, Forest Haven Subdivision is a very small system (500 people or fewer). Clackamas County has 241 active public water systems. Its population served is well below the county average of 1,602 people per system, and accounts for less than 0.1% of the 385,972 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active community water system reports serving 6,703 people, so Forest Haven Subdivision 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. Oregon has 940 active community water systems, 37% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
Who owns and regulates Forest Haven Subdivision?
EPA lists Forest Haven Subdivision as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 155 of the 241 active systems in Clackamas County (64%) are also privately owned.
Does Forest Haven Subdivision have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2025. The violations listed here began between January 2020 and December 2025. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Coliphage (8 of them). EPA lists 10 as resolved, 1 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.
