Homes, apartments and mobile-home parks are served by these. New Hampshire has 706 active community water systems, 29% 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 River Run?

Does River Run have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in June 2018. The violations listed here began between January 1995 and June 2018. By type: 7 monitoring and reporting, 3 required treatment not met and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Groundwater Rule (3 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.
