STONY BROOK is one of 877 community water systems in New Hampshire in the 500 or fewer people size category, formerly serving 167 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 21 entries between 2009 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

All 21 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 and volatile organic chemicals.
