Saltwater intrusion
Uh oh. Salt water contaminating the drinking water in a highly populated area.
Drought-like conditions in the Midwest over the summer have created a growing water problem in the New Orleans area this fall.
Water levels of the Mississippi River have dropped low enough to make the river less resistant to a mass of saltwater flowing north from the Gulf of Mexico. This circumstance, known as saltwater intrusion, is endangering the drinking water systems in and around the city, as well as smaller municipalities to the south.
Is that scary enough yet?
Officials in Louisiana and with the U.S. Army Corps of Engineers say that a “saltwater wedge” could reach water treatment plants near New Orleans in October and are working to slow the influx while also bringing in more fresh water to the region. Many water treatment facilities cannot handle water with high salinity levels, which corrode pipes and cause metals in the pipes to leach into the water.
…
The Corps of Engineers is also getting barges to transport water that can be combined with water at the treatment facilities for safe drinking. Colonel Jones said about 15 million gallons will be delivered in the coming days, but the demand at treatment facilities could ultimately rise to at least 36 million gallons per day. Colonel Jones said that the Army Corps was working to get access to more barges but that he was confident that figure could be met.
And that’s very easy and sustainable (and not at all yet another addition to the problem). Just ship in 36 million gallons of water every day. Piece of cake.
Many coastal communities, like parts of the Jersey Shore, Long Island and the Outer Banks of North Carolina, are no stranger to saltwater intrusion, which also occurs when storm surges or high tides top areas that are low in elevation. As sea levels rise along the coasts, the threat of saltwater intrusion does, too. Other countries like Bangladesh are grappling with that reality.
Nah, it’s just liberal scaremongering. Buy another SUV to piss them off.

It’s also an issue in Florida. I saw an episode of Engineering Catastrophes where it was discussed. Something about how the saltwater can eat away at building foundations, increasing the risk of collapse.
