CEDAR PARK MANOR MOBILE HOMES is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 37 people from groundwater.
EPA's federal records list this system as inactive in 1997; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries between 1976 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 6 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 Lead and Copper Rule, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
