GRAND ISLE WATER SYSTEM is one of 536 community water systems in Maine in the 500 or fewer people size category, serving 278 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 2014 and 2025, all of which EPA lists as closed.

All 12 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 volatile organic chemicals, the Lead and Copper Rule, and the Total Coliform Rules.
