Sierra Water System is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 355 people from groundwater.

As of August 1, 2026, its federal record holds 42 entries between 1998 and 2025, all of which EPA lists as closed.

Of the 42, 41 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 the Total Coliform Rules.
