How does Housatonic Water Works compare with other water systems in Berkshire County?
By EPA's size categories, Housatonic Water Works is a small system (501 to 3,300 people). Berkshire County has 183 active public water systems. Its population served is about twice the county average of 730 people per system, and accounts for 1% of the 133,497 people reported by systems filed under the county.

Nationally, the average active community water system reports serving 6,703 people, so Housatonic Water Works 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. Massachusetts has 531 active community water systems, 32% of the state's 1,636 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 76 Massachusetts systems (4.6%) list surface water as their primary source.
Who owns and regulates Housatonic Water Works?
EPA lists Housatonic Water Works 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. 140 of the 183 active systems in Berkshire County (77%) are also privately owned.
Does Housatonic Water Works have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2021. The violations listed here began between January 2013 and October 2021. By type: 7 monitoring and reporting, 2 public notice, recordkeeping or other, 2 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Haloacetic acids (HAA5) (3 of them). EPA lists 5 as resolved, 4 as addressed 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
