COLTON WATER DEPARTMENT is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 632 people from groundwater.

As of August 1, 2026, its federal record holds 34 entries between 1979 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 34, 32 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 synthetic organic chemicals, inorganic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
