RAINBOW HAVEN MHP is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 88 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 7 entries between 1978 and 1988, all of which EPA lists as closed. Nothing has been added since 1988.
