MOUNTAIN LAKES WATER DISTRICT is one of 101 community water systems in New Hampshire in the 501 to 3,300 people size category, serving 787 people from groundwater.

As of August 1, 2026, its federal record holds 20 entries between 1993 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.

All 20 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 and synthetic organic chemicals.
