OUR LADY OF GRACE MONASTERY is one of 799 community water systems in Connecticut in the 500 or fewer people size category, formerly serving 23 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 30 entries between 1990 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 30, 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 Consumer Confidence Rule.
