The Impending Saltwater Crisis: Louisiana's Battle for Fresh Drinking Water

A prolonged drought in Louisiana has led to low freshwater levels in the Mississippi River, making it susceptible to saltwater intrusion from the Gulf of Mexico. This poses a threat to the drinking water of the state's nearly 5 million residents, particularly those in the New Orleans area. Louisiana Governor John Bel Edwards is considering requesting a federal emergency declaration, while New Orleans Mayor LaToya Cantrell has already signed an emergency declaration for the city. Efforts to combat saltwater intrusion include building an underwater sill in the river, but the best solution would be above-average precipitation in the Ohio Valley. Climate change is exacerbating the situation, with increased droughts and extreme weather events impacting Louisiana.
