By EPA's size categories, 85 Swanson Rd LLC is a very small system (500 people or fewer). Middlesex County has 204 active public water systems.

Nationally, the average active non-transient non-community water system reports serving 430 people, so 85 Swanson Rd LLC 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 85 Swanson Rd LLC?
EPA lists 85 Swanson Rd LLC 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. 127 of the 204 active systems in Middlesex County (62%) are also privately owned.
Does 85 Swanson Rd LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2010. The violations listed here began between April 1998 and October 2010. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 10 as archived and 2 as resolved. 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.
