ALTON WATER WORKS is one of 101 community water systems in New Hampshire in the 501 to 3,300 people size category, serving 1,800 people from groundwater.

As of August 1, 2026, its federal record holds 39 entries between 1994 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 39, 38 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, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
