The Mississippi River has been closed temporarily as contractors placed a pipeline in the Mississippi River to build an underwater barrier that the Army Corps of Engineers says will stop the advance of salt water threatening drinking water in the New Orleans area.
Due to low water levels in the Mississippi River, salt water has been moving far upriver and was at the outskirts of New Orleans by Wednesday, reaching 89 miles north of the mouth of the Mississippi.
Also Wednesday, Plaquemines Parish issued an advisory to residents living in the parish that high levels of sodium and chloride were being measured in drinking water.
