GRAND ISLE WATER SYSTEM is one of 509 community water systems in Louisiana in the 501 to 3,300 people size category, formerly serving 2,450 people from surface water.
EPA's federal records list this system as inactive in 2005; the record below is historical.
As of August 1, 2026, its federal record holds 2 entries between 2001 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
Of the 2, 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 Stage 1 Disinfectants and Disinfection Byproducts Rule and the Total Coliform Rules.
