How does Coos Golf Club compare with other water systems in Coos County?
By EPA's size categories, Coos Golf Club is a very small system (500 people or fewer). Coos County has 45 active public water systems. Its population served is well below the county average of 1,143 people per system, and accounts for less than 0.1% of the 51,436 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Coos Golf Club is well below that figure.
What does “transient non-community water system” mean?

Oregon has 1,250 active transient non-community water systems, 49% of the state's 2,536 active systems.

Does Coos Golf Club 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 August 2023 and December 2025. By type: 10 monitoring and 2 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (10 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.
