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 Silver Inn?

Does Silver Inn have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between April 2012 and January 2026. By type: 6 monitoring and reporting, 5 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 10 as resolved and 2 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.
