How does Star Ridge compare with other water systems in Grafton County?
By EPA's size categories, Star Ridge is a very small system (500 people or fewer). Grafton County has 270 active public water systems. Its population served is well below the county average of 394 people per system, and accounts for less than 0.1% of the 106,236 people reported by systems filed under the county. Across New Hampshire, the 2,450 active systems average 508 people each. Nationally, the average active community water system reports serving 6,703 people, so Star Ridge is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. 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 Star Ridge?
EPA lists Star Ridge 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. 213 of the 270 active systems in Grafton County (79%) are also privately owned.
Does Star Ridge have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in April 2022. The violations listed here began between November 2006 and April 2022. By type: 5 contaminant level above the legal limit, 5 public notice, recordkeeping or other, 1 reporting and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 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.
