An influx of salt water in the Mississippi River, which supplies drinking water to southeastern Louisiana, is once again causing concern. For the third consecutive year, efforts are underway to construct an underwater levee to impede the encroachment of brackish water and safeguard water intake treatment facilities.
Salt water intrusion in this region has become a recurring issue due to the reduced flow of the Mississippi River under dry conditions. The communities in southeastern Louisiana rely on the river's volume and current to push salt water from the Gulf of Mexico back out to sea.
