How does Boxborough Regency compare with other water systems in Middlesex County?
By EPA's size categories, Boxborough Regency is a very small system (500 people or fewer). Middlesex County has 204 active public water systems. Its population served is well below the county average of 7,986 people per system, and accounts for less than 0.1% of the 1,629,099 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 Boxborough Regency is about 16% above 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 Boxborough Regency?
EPA lists Boxborough Regency 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 Boxborough Regency have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in August 2016. The violations listed here began between July 2002 and August 2016. By type: 7 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 7 as archived and 5 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.
