RSK REALTY 1 is one of 799 community water systems in Connecticut in the 500 or fewer people size category, formerly serving 36 people from groundwater.

EPA's federal records list this system as inactive in 2015; the record below is historical.

As of August 1, 2026, its federal record holds 24 entries between 2002 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.

Of the 24, 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, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
