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 .
That is a sentiment echoed by officials across the state, as the drought-stricken Mississippi River’s flow is low and slow, allowing for salt water from the Gulf of Mexico to intrude upstream ...
New Orleans' water supply is no longer under a current threat of salt water intrusion as conditions improve along the Mississippi River, according to latest estimate by the U.S. Army Corps of ...
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.
This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Officials in Louisiana are warning that saltwater coming up from the Gulf of Mexico could affect the availability of safe drinking water for millions of people along the Mississippi River.
BATON ROUGE, La. (AP) — An influx of salt water in the Mississippi River, which feeds southeastern Louisiana's drinking water supplies, is once again creeping up the waterway. For the third year in a row, an underwater levee is being built to slow the brackish intrusion and prevent it from reaching water intake treatment facilities.
