By EPA's size categories, Camp Namanu-Ranch is a very small system (500 people or fewer). Clackamas County has 241 active public water systems.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Oregon has 1,250 active transient non-community water systems, 49% 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 Camp Namanu-Ranch?

EPA lists Camp Namanu-Ranch 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 Camp Namanu-Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2023. The violations listed here began between April 2014 and July 2023. By type: 6 monitoring, 3 monitoring and reporting, 1 required treatment not met, 1 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (7 of them). EPA lists 11 as resolved and 1 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.
