How does Riverside Terrace compare with other water systems in Somerset County?
By EPA's size categories, Riverside Terrace is a very small system (500 people or fewer). Somerset County has 100 active public water systems. Its population served is roughly in line with the county average of 344 people per system, and accounts for 1% of the 34,437 people reported by systems filed under the county. Across Maine, the 1,862 active systems average 503 people each. Nationally, the average active community water system reports serving 6,703 people, so Riverside Terrace is well below that figure.
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 Riverside Terrace?
EPA lists Riverside Terrace as privately owned. 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. 84 of the 100 active systems in Somerset County (84%) are also privately owned.
Does Riverside Terrace 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 2023. The violations listed here began between June 2009 and January 2023. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (4 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.
