Louisiana builds third underwater levee to combat saltwater intrusion risking drinking water supply due to reduced river flow.
Louisiana is building an underwater levee in the Mississippi River for the third year to combat saltwater intrusion from the Gulf of Mexico, which risks the drinking water supply. This issue has intensified due to reduced river flow linked to dry conditions. Monitoring efforts are in place, and while no immediate threats have been reported, past measures have included transporting fresh water and issuing boil advisories. An emergency declaration was made for New Orleans in 2023.
