UPDATE: On Wednesday (Nov. 23), the Jefferson Parish Water Department lifted the Boil Water Advisory for Grand Ilse from Cheniere to Rosethorn Lane. Customers may now use the water without boiling or disinfecting.

GRAND ISLE, La. (WGNO) — A boil water advisory was put in place in Jefferson Parish for parts of Grand Isle.
