BLOCK ISLAND WATER COMPANY is among the 16 largest community water systems in Rhode Island, serving 9,999 people from groundwater.
As of August 1, 2026, its federal record holds 42 entries between 1994 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 42, 37 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 Former Total Trihalomethane Rule.
