How does Tamworth Preschool compare with other water systems in Carroll County?

By EPA's size categories, Tamworth Preschool is a very small system (500 people or fewer). Carroll County has 366 active public water systems. Its population served is about half of the county average of 221 people per system, and accounts for 0.1% of the 81,013 people reported by systems filed under the county. Across New Hampshire, the 2,450 active systems average 508 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Tamworth Preschool 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. New Hampshire has 453 active non-transient non-community water systems, 18% of the state's 2,450 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,374 New Hampshire systems (97%) list groundwater as their primary source.

Who owns and regulates Tamworth Preschool?

EPA lists Tamworth Preschool as privately owned. The NH state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 328 of the 366 active systems in Carroll County (90%) are also privately owned.

Does Tamworth Preschool have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in June 2013. The violations listed here began between January 2007 and June 2013. By type: 8 monitoring and reporting, 3 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 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.
