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. Maine has 386 active community water systems, 21% of the state's 1,862 active systems. 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 Limerick Water District?
EPA lists Limerick 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. 26 of the 188 active systems in York County (14%) are also owned by a local government.
Does Limerick Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2025. The violations listed here began between January 2015 and January 2025. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (3 of them). EPA lists 10 as resolved 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. 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.
