Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,780 Maine systems (96%) list groundwater as their primary source.
Who owns and regulates West Paris Water District?
EPA lists West Paris Water District as owned by a local government. The ME state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 18 of the 133 active systems in Oxford County (14%) are also owned by a local government.
Does West Paris Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in July 2025. The violations listed here began between December 2019 and July 2025. By type: 5 monitoring and reporting, 4 required treatment not met, 2 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (5 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.
