COLONY SURF WATER SUPPLY is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 297 people from groundwater.

As of August 1, 2026, its federal record holds 48 entries between 1979 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 48, 45 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, inorganic chemicals, and the Total Coliform Rules.
