LOOKOUT POINT ASSN. is one of 450 community water systems in Massachusetts in the 500 or fewer people size category, formerly serving 66 people from groundwater.

EPA's federal records list this system as inactive in 2002; the record below is historical.

As of August 1, 2026, its federal record holds 11 entries between 1982 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.

Of the 11, 9 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, the Radionuclides and Revised Rad Rule, and the Miscellaneous Other Rules.
