SEA CLIFF ESTATES is one of 428 community water systems in Washington in the 501 to 3,300 people size category, formerly serving 2,602 people from groundwater.

EPA's federal records list this system as inactive in 2020; the record below is historical.

As of August 1, 2026, its federal record holds 65 entries between 1992 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

Of the 65, 59 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 synthetic organic chemicals, inorganic chemicals, and the Total Coliform Rules.
