WILLIAMSBURG is one of 101 community water systems in New Hampshire in the 501 to 3,300 people size category, serving 910 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries in 1993, all of which EPA lists as closed. Nothing has been added since 1993.
All 3 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.
