How does North Harbor compare with other water systems in Chittenden County?
By EPA's size categories, North Harbor is a very small system (500 people or fewer). Chittenden County has 96 active public water systems. Its population served is well below the county average of 1,566 people per system, and accounts for 0.1% of the 150,374 people reported by systems filed under the county. Across Vermont, the 1,357 active systems average 477 people each. Nationally, the average active community water system reports serving 6,703 people, so North Harbor 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. Vermont has 405 active community water systems, 30% of the state's 1,357 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,243 Vermont systems (92%) list groundwater as their primary source.
Who owns and regulates North Harbor?
EPA lists North Harbor as privately owned. The VT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 59 of the 96 active systems in Chittenden County (61%) are also privately owned.
Does North Harbor have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in July 2019. The violations listed here began between August 2001 and July 2019. By type: 6 monitoring and reporting and 6 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 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.
