"Saltwater Intrusion Threatens New Orleans Drinking Water as Mississippi River Faces Climbing Wedge"

The Mississippi River is facing a threat from a saltwater wedge that is climbing up the river due to a combination of drought and low river flow. The encroaching saltwater could potentially contaminate drinking water supplies, undermine agriculture, and damage infrastructure in Louisiana. The U.S. Army Corps of Engineers is taking action to slow down the progression of saltwater by expanding an underwater barrier. However, if current conditions persist, the barrier may be overtopped. Saltwater intrusion can have corrosive effects on appliances and equipment, harm crops, and complicate livestock care. The situation highlights the impact of climate change, drought, and sea level rise on the Mississippi River and the need to safeguard its viability.
