MAPLE GROVE is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 132 people from groundwater.

As of August 1, 2026, its federal record holds 44 entries between 2003 and 2025, all of which EPA lists as closed.

Of the 44, 40 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 volatile organic chemicals, the Consumer Confidence Rule, and the Total Coliform Rules.
