ALDERBROOK WATER CO is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 2,154 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1979 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.
Of the 5, 4 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 the Total Coliform Rules and the Radionuclides and Revised Rad Rule.
