STERLING WATER DEPARTMENT is one of 93 community water systems in Massachusetts in the 3,301 to 10,000 people size category, serving 6,715 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1993 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.

Of the 6, 5 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 and the Total Coliform Rules.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
