JEFFERSON is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 12 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 4 entries between 2004 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
