WESTERLY WATER DEPARTMENT is among the 9 largest community water systems in Rhode Island, serving 35,298 people from groundwater.
As of August 1, 2026, its federal record holds 41 entries between 1991 and 2024, all of which EPA lists as closed.
Of the 41, 39 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.
