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 White Mtn Regional Hs?
EPA lists White Mtn Regional Hs as owned by a local government. 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. 18 of the 112 active systems in Coos County (16%) are also owned by a local government.
Does White Mtn Regional Hs have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in September 2020. The violations listed here began between January 2000 and September 2020. By type: 6 monitoring and reporting, 2 monitoring, 2 reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 11 as resolved and 1 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.
