COLUMBIA POWER AND WATER SYSTEMS is among the 15 largest community water systems in Tennessee, serving 84,617 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1984 and 1991, all of which EPA lists as closed. Nothing has been added since 1991.
Of the 3, 1 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 Former Total Trihalomethane Rule and the Total Coliform Rules.
