Saltwater Intrusion: A Looming Threat to Louisiana's Water Supply and New Orleans

Saltwater intrusion is threatening Louisiana's water supplies, including the possibility of reaching New Orleans, due to low water levels in the Mississippi River caused by drought and conditions in the upper parts of the river and the Ohio River Valley. Saltwater contamination has already affected some areas, leading to drinking water advisories. Officials are working to mitigate the issue, including bringing fresh water via barge and exploring alternative water sources. The corrosion caused by saltwater could potentially lead to lead exposure if pipes containing heavy metals are damaged. Climate projections suggest that saltwater intrusion could become more frequent in the future, requiring long-term solutions.
