Nationally, the average active transient non-community water system reports serving 144 people, so Merlin Mobile Home Park 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. 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 Merlin Mobile Home Park?
EPA lists Merlin Mobile Home Park 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. 108 of the 150 active systems in Josephine County (72%) are also privately owned.
Does Merlin Mobile Home Park have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in March 2026. The violations listed here began between January 2020 and March 2026. By type: 6 monitoring and reporting, 3 monitoring, 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 Groundwater Rule (4 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.
