LOCKE LAKE is one of 101 community water systems in New Hampshire in the 501 to 3,300 people size category, serving 2,308 people from surface water.

As of August 1, 2026, its federal record holds 19 entries between 1993 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.

Of the 19, 18 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 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.
