What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Missouri has 1,612 active community water systems, 55% of the state's 2,943 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 177 Missouri systems (6%) list purchased groundwater as their primary source.
Who owns and regulates Anniston Pws?

The MO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 6 of the 6 active systems in Mississippi County (100%) are also owned by a local government.
Does Anniston Pws 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 January 2021 and July 2025. By type: 4 public notice, recordkeeping or other, 4 monitoring and reporting, 2 monitoring, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (2 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 as archived. 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. 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.
