PATTERSON MHP is one of 498 community water systems in Vermont in the 500 or fewer people size category, formerly serving 55 people from surface water.

EPA's federal records list this system as inactive in 2012; the record below is historical.

As of August 1, 2026, its federal record holds 9 entries between 1991 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

All 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 the Total Coliform Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
