Homes, apartments and mobile-home parks are served by these. Idaho has 765 active community water systems, 39% 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 Hope House (Owyhee)?
EPA lists Hope House (Owyhee) 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. 16 of the 24 active systems in Owyhee County (67%) are also privately owned.
Does Hope House (Owyhee) have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in September 2025. The violations listed here began between January 2019 and September 2025. By type: 7 monitoring and reporting, 3 required treatment not met and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Chlorine (4 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
