MIDLAND HILLS WATER COMPANY is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 140 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 18 entries between 1976 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
Of the 18, 15 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.
