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. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 66 Idaho systems (3.4%) list surface water as their primary source.
Who owns and regulates Paradise Valley Water Assn?

Does Paradise Valley Water Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2025. The violations listed here began between June 1998 and July 2025. By type: 10 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Haloacetic acids (HAA5) (3 of them). EPA lists 7 as resolved, 4 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.
