LISBON WATER SYSTEM is one of 509 community water systems in Louisiana in the 501 to 3,300 people size category, serving 891 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 2011 and 2026, all of which EPA lists as closed.
Of the 11, 2 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Consumer Confidence Rule, and the Groundwater Rule.
