You may have seen news stories about the saltwater intrusion in the Mississippi River and the impact it may have on the water supply of communities upstream. The LRA Team, along with the Louisiana Dept. of Health (LDH) Engineering Team, is working to prepare members for the impact this could have on our residents and restaurants, should the situation worsen. The LDH in conjunction with the U.S. Army Corps of Engineers (Corps) are collaborating on communication and the construction of a higher underwater dam to stem the flow of salt water upriver.
Here are a few things to consider:
Timeline Forecast: In discussion with the LDH Engineering Dept., the timeline forecast for the when the saltwater wedge reaches the intake at the following water systems is projected as follows: October 8 St. Bernard October 10 Algiers October 11 West Jefferson TBD Carrollton (New Orleans) Once the saltwater reaches the intake, it could be a few weeks before it could disrupt the water supply given the concentration of the water system’s chloride functions. This would not create a boil water advisory, as the issue with saltwater is not bacterial, but corrosion of plumbing systems, which may leach metals in the water supply. The LRA Team will continue to monitor this situation and provide updates as necessary.
