Massive barges brought over a million gallons of fresh water to Plaquemines Parish, Louisiana, on Monday as the community tackles the intrusion of saltwater that’s threatening drinking supplies.
Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater .

Dykes, an igneous unit that is impermeable or low in hydraulic conductivity might stop the intrusion of seawater. [28] Faults also affect the direction of water flow which is studied by Fault Zone Hydrogeology. Both regular and catastrophic flooding can cause downward intrusion of seawater recreating the transition zone of the fresh-salt water ...
Overdrafting in coastal regions can lead to the reduction of water pressure in an aquifer, allowing saltwater intrusion. If saltwater contaminates a freshwater aquifer, that aquifer can no longer be used as a reliable source of freshwater for settlements and cities. Artificial recharge may return fresh water pressure to halt saltwater intrusion.
Officials say the sill augmentation — which had been used during similar situations, in 1988, 2012 and last year — will delay salt water’s progression by about 10 to 15 days. “We’re ...
Salt water began to make its way upstream toward Lake Union, requiring a system of siphons and flushing mechanisms. Because the Cedar River was the main water source both for the lakes and locks and for Seattle's potable water, at times there were problems maintaining an adequate water supply to maintain lake level and operate the locks.
