HIGHLAND PARK APTS is one of 3,227 community water systems in Washington in the 500 or fewer people size category, formerly serving 138 people from groundwater.
EPA's federal records list this system as inactive in 1998; the record below is historical.
As of August 1, 2026, its federal record holds 16 entries between 1979 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
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, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
