SKYLINE WATER SYSTEM INC is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 293 people from groundwater.
As of August 1, 2026, its federal record holds 16 entries between 1979 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
All 16 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 inorganic chemicals, synthetic organic chemicals, and the Total Coliform Rules.
