How does Semass Resource Recovery Facility compare with other water systems in Plymouth County?
By EPA's size categories, Semass Resource Recovery Facility is a very small system (500 people or fewer). Plymouth County has 129 active public water systems. Its population served is well below the county average of 4,447 people per system, and accounts for less than 0.1% of the 573,676 people reported by systems filed under the county. Across Massachusetts, the 1,636 active systems average 6,275 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Semass Resource Recovery Facility 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. Massachusetts has 246 active non-transient non-community water systems, 15% of the state's 1,636 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.
Who owns and regulates Semass Resource Recovery Facility?
EPA lists Semass Resource Recovery Facility as privately owned. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 85 of the 129 active systems in Plymouth County (66%) are also privately owned.
Does Semass Resource Recovery Facility have drinking water violations?
EPA's records list 5 violations for this system; 4 are health-based, and the most recent began in August 2012. The violations listed here began between April 2004 and August 2012. By type: 4 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 3 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.
