What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. North Dakota has 317 active community water systems, 79% of the state's 403 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 114 North Dakota systems (28%) list purchased groundwater as their primary source.
Who owns and regulates City of Max?
EPA lists City of Max as owned by a local government. The ND state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 9 of the 13 active systems in McLean County (69%) are also owned by a local government.
Does City of Max have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2026. The violations listed here began between May 1998 and January 2026. By type: 6 monitoring and reporting, 3 public notice, recordkeeping or other, 2 disinfectant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Chloramine (5 of them). EPA lists 6 as resolved, 4 as archived and 2 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.
