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 ...
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 .
The Mississippi River is facing a crisis of saltwater making its way up the waterway from the Gulf of Mexico. Drinking water in some parts of Louisiana is facing a risk from the salt water ...
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 ...
On Monday, the corps of engineers began building a sill across the river bed in Myrtle Grove, about 30 miles (48 kilometers) south of New Orleans. The sill is meant to slow or halt salt water, which flows along the bottom of the river because it's more dense than fresh water. Building the sill with river sand is estimated to be completed by ...
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 ...
The Mississippi River has the world's fourth-largest drainage basin ("watershed" or "catchment"). The basin covers more than 1,245,000 square miles (3,220,000 km 2), including all or parts of 32 U.S. states and two Canadian provinces. The drainage basin empties into the Gulf of Mexico, part of the Atlantic Ocean. The total catchment of the ...
The steady push of salt water upstream in the drought-hit Mississippi River could have serious health and economic consequences across southern Louisiana, where many communities rely on the river ...
