Homes, apartments and mobile-home parks are served by these. Arizona has 936 active community water systems, 53% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.
Who owns and regulates Green Valley MHP?
EPA lists Green Valley MHP as under public/private ownership. The AZ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 92 of the 238 active systems in Yavapai County (39%) are also under public/private ownership.
Does Green Valley MHP have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2026. The violations listed here began between October 2024 and January 2026. By type: 6 public notice, recordkeeping or other, 5 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Public Notice (6 of them). EPA lists 6 as unaddressed, 5 as archived and 1 as resolved. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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. 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.
