RUMBOLZ SUNSET WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 106 people from groundwater.

As of August 1, 2026, its federal record holds 33 entries between 1997 and 2025, all of which EPA lists as closed.

Of the 33, 26 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 Total Coliform Rules, and the Consumer Confidence Rule.

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