HILAND WC - NORTHRIDGE WATER CO is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 150 people from groundwater.

EPA's federal records list this system as inactive in 2015; the record below is historical.

As of August 1, 2026, its federal record holds 20 entries between 1995 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 20, 11 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 Public Notice Rule and Revised PN Rule.
