WILSONS MHP is one of 877 community water systems in New Hampshire in the 500 or fewer people size category, serving 30 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1993 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 5 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.
