HILLSBOROUGH WATER WORKS is one of 101 community water systems in New Hampshire in the 501 to 3,300 people size category, serving 2,000 people from surface water.
As of August 1, 2026, its federal record holds 14 entries between 1994 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 14, 9 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and volatile organic chemicals.
