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. Idaho has 954 active transient non-community water systems, 49% of the state's 1,961 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,861 Idaho systems (95%) list groundwater as their primary source.

Who owns and regulates 7n Ranch?

EPA lists 7n Ranch as privately owned. The ID state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 50 of the 61 active systems in Jefferson County (82%) are also privately owned.

Does 7n 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 December 2025. The violations listed here began between July 2001 and December 2025. By type: 5 monitoring and reporting, 3 monitoring, 2 public notice, recordkeeping or other and 2 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 5 as archived, 4 as unaddressed and 3 as resolved. 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. 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.
