DELAWARE CO RWD #12 is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 412 people from surface water.
EPA's federal records list this system as inactive in 2013; the record below is historical.
As of August 1, 2026, its federal record holds 24 entries between 2003 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 24, 16 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 volatile organic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
