MABTON CITY OF is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 2,150 people from groundwater.

As of August 1, 2026, its federal record holds 115 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 115, 114 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 volatile organic chemicals.
