How does Ellis Haven compare with other water systems in Plymouth County?

By EPA's size categories, Ellis Haven is a very small system (500 people or fewer). Plymouth County has 129 active public water systems. Its population served is well below the county average of 4,447 people per system, and accounts for less than 0.1% of the 573,676 people reported by systems filed under the county.

Nationally, the average active transient non-community water system reports serving 144 people, so Ellis Haven is about 178% above that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Massachusetts has 859 active transient non-community water systems, 53% of the state's 1,636 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.

Who owns and regulates Ellis Haven?

EPA lists Ellis Haven as privately owned. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 85 of the 129 active systems in Plymouth County (66%) are also privately owned.

Does Ellis Haven have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in November 2022. The violations listed here began between April 1995 and November 2022. By type: 5 monitoring and reporting, 3 reporting, 3 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (7 of them). EPA lists 7 as archived and 5 as resolved. 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. 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.
