RIVER TERRACE is one of 3,227 community water systems in Washington in the 500 or fewer people size category, formerly serving 36 people from groundwater.

EPA's federal records list this system as inactive in 1996; the record below is historical.

As of August 1, 2026, its federal record holds 31 entries between 1979 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.

Of the 31, 29 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, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
