CTWC - SHORELINE REGION-GUILFORD SYSTEM is among the 21 largest community water systems in Connecticut, serving 33,975 people from surface water.
As of August 1, 2026, its federal record holds 53 entries between 2004 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.
All 53 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 synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.
