NORTHBOROUGH WATER DEPARTMENT (MWRA) is one of 168 community water systems in Massachusetts in the 10,001 to 100,000 people size category, serving 13,551 people from surface water.
As of August 1, 2026, its federal record holds 14 entries between 1993 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
All 14 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, inorganic chemicals, and synthetic organic chemicals.
