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.

Does Powwow Junction have drinking water violations?
EPA's records list 9 violations for this system; none is health-based, and the most recent began in July 2017. The violations listed here began between October 2013 and July 2017. By type: 4 monitoring and reporting, 2 reporting, 2 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them).
