How does Sterling Nursery School compare with other water systems in Worcester County?
By EPA's size categories, Sterling Nursery School is a very small system (500 people or fewer). Worcester County has 346 active public water systems.

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 Sterling Nursery School is about 65% 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 Sterling Nursery School?
EPA lists Sterling Nursery School 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. 252 of the 346 active systems in Worcester County (73%) are also privately owned.
Does Sterling Nursery 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 July 2013. The violations listed here began between January 2013 and July 2013. By type: 9 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Arsenic (4 of them). EPA lists 9 as resolved and 3 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.
