WINTERGREEN is one of 799 community water systems in Connecticut in the 500 or fewer people size category, formerly serving 40 people from groundwater.
EPA's federal records list this system as inactive in 2008; the record below is historical.
As of August 1, 2026, its federal record holds 15 entries between 1994 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 15, 12 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 inorganic chemicals, the Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
