CTWC - SOUTH COVENTRY SYSTEM is one of 84 community water systems in Connecticut in the 501 to 3,300 people size category, serving 501 people from groundwater.
As of August 1, 2026, its federal record holds 22 entries between 2006 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
Of the 22, 21 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, synthetic organic chemicals, and inorganic chemicals.
