Battling a Water Crisis: Bottles, Barges and Maybe a Quarter Billion-Dollar Pipe [1]

['Jacey Fortin']

Date: 2023-09-29

People in New Orleans are used to preparing for hurricanes and floods. So when they learned of a new threat — an infusion of salty water creeping slowly up the Mississippi River, threatening municipal drinking water supplies — they did what comes naturally: strip bottled water from grocery store shelves.

But this is a crisis with even more lead time than a storm churning in the Gulf of Mexico: The worst of the saltwater intrusion isn’t expected to reach the city until late October. And the salty water could stick around for much longer, potentially corroding the city’s lead-lined pipes.

“It’s kind of a perfect storm,” said Jesse Keenan, a climate adaptation expert at Tulane University.

The crisis is a result of drought conditions in the Midwest, which have sapped water levels in the Mississippi, allowing salty water from the Gulf to creep upstream beneath a freshwater layer.
