HEMLOCK HILLS is one of 877 community water systems in New Hampshire in the 500 or fewer people size category, formerly serving 12 people from groundwater.
EPA's federal records list this system as inactive in 2001; the record below is historical.
As of August 1, 2026, its federal record holds 39 entries between 1994 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
All 39 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.
