AQUARION-BERKSHIRE is one of 799 community water systems in Connecticut in the 500 or fewer people size category, serving 75 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 2003 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 3, 2 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Public Notice Rule and Revised PN Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
