MCI SHIRLEY is one of 93 community water systems in Massachusetts in the 3,301 to 10,000 people size category, serving 3,500 people from groundwater.

As of August 1, 2026, its federal record holds 2 entries between 2002 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.

All 2 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 the Total Coliform Rules and volatile organic chemicals.

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
