GREENFIELD PWA is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 123 people from groundwater.

EPA's federal records list this system as inactive in 1902; the record below is historical.

As of August 1, 2026, its federal record holds 16 entries between 1991 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.
