CTWC - NORTHERN REG-CRESCENT LAKE SYSTEM is one of 84 community water systems in Connecticut in the 501 to 3,300 people size category, formerly serving 680 people from groundwater.

EPA's federal records list this system as inactive in 2014; the record below is historical.

As of August 1, 2026, its federal record holds 10 entries between 2005 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 10, 6 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.
