AQUARION-ROLLING RIDGE is one of 799 community water systems in Connecticut in the 500 or fewer people size category, serving 115 people from surface water.
As of August 1, 2026, its federal record holds 11 entries between 2004 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 11, 10 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Surface Water Treatment Rules, and the Total Coliform Rules.
