How does Sebago Elementary School compare with other water systems in Cumberland County?
By EPA's size categories, Sebago Elementary School is a very small system (500 people or fewer). Cumberland County has 225 active public water systems. Its population served is well below the county average of 967 people per system, and accounts for less than 0.1% of the 217,594 people reported by systems filed under the county. Across Maine, the 1,862 active systems average 503 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Sebago Elementary School is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Maine has 385 active non-transient non-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 Sebago Elementary School?
EPA lists Sebago Elementary School 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. 24 of the 225 active systems in Cumberland County (11%) are also owned by a local government.
Does Sebago Elementary School have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in September 2025. The violations listed here began between September 2023 and September 2025. By type: 8 monitoring and reporting, 3 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (11 of them). EPA lists 4 as unaddressed, 4 as archived and 4 as resolved. 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. 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.
