COUPEVILLE TOWN OF is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 4,142 people from groundwater.

As of August 1, 2026, its federal record holds 56 entries between 1979 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

The record involves inorganic chemicals, volatile organic chemicals, and synthetic organic chemicals.
