New Orleans' drinking water threatened as saltwater intrusion looms

Millions of Louisiana residents are facing a possible drinking water crisis as saltwater from the Gulf of Mexico threatens to contaminate the freshwater supply. The saltwater intrusion, caused by a severe summer drought that lowered the Mississippi River's water levels, could have serious consequences, as many local water treatment facilities are ill-equipped to handle high salt content, which can corrode pipes and pose health risks when consumed.

The U.S. Army Corps of Engineers is working to prevent an impending crisis in the southernmost stretch of the Mississippi River, but the situation remains critical.

"We're into preparedness and awareness. What we want to make sure is that everybody knows what we're facing," said Ricky Boyett of the Army Corps of Engineers.
