CANADIAN CO WATER AUTHORITY is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 1,700 people from surface water.
As of August 1, 2026, its federal record holds 7 entries between 2000 and 2024, all of which EPA lists as closed.
Of the 7, 4 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 Consumer Confidence Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
