How does Narraguagus Estates compare with other water systems in Washington County?
By EPA's size categories, Narraguagus Estates is a very small system (500 people or fewer). Washington County has 109 active public water systems. Its population served is about half of the county average of 205 people per system, and accounts for 0.4% of the 22,334 people reported by systems filed under the county.

What does “community water system” mean?

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 Narraguagus Estates?

Does Narraguagus Estates have drinking water violations?
EPA's records list 10 violations for this system; 4 are health-based, and the most recent began in July 2022. The violations listed here began between January 1993 and July 2022. By type: 5 monitoring and reporting, 4 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 9 as resolved and 1 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.
