HOCKINSON is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, formerly serving 7,062 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 3 entries between 1979 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
Of the 3, 2 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 and the Radionuclides and Revised Rad Rule.
