CANTERWOOD WATER SYSTEM is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,805 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1992 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 9, 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 the Total Coliform Rules, synthetic organic chemicals, and inorganic chemicals.

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.
