COMBINED WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 435 people from groundwater.

As of August 1, 2026, its federal record holds 53 entries between 1998 and 2025, of which 1 remains open; none are health-based.

Of the 53, 52 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, volatile organic chemicals, and inorganic chemicals.

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