HANOVER WATER DEPT is among the 20 largest community water systems in New Hampshire, serving 9,600 people from surface water.

As of August 1, 2026, its federal record holds 7 entries between 1994 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.

Of the 7, 4 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 inorganic chemicals, the Surface Water Treatment Rules, and the Total Coliform Rules.

What is a Consumer Confidence Report?

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.
