Answer 1

Answer:

so the answer will we .A it is the answer

Answer 2

Answer:

Explanation:

Saltwater Intrusion:

The migration of saltwater into freshwater aquifers is known as saltwater intrusion, and it can have negative effects on groundwater quality, especially drinking water supplies. Aquifers at coastlines may naturally experience saltwater intrusion due to the hydraulic connection between groundwater and seawater. Saline water is denser and has a higher water pressure than freshwater because it contains more minerals. Because of this, saltwater may move inland beneath freshwater.

When the saltwater from the sea and the fresh water aquifer have differing densities, saltwater intrusion occurs, allowing ocean water to seep into the fresh water aquifer through the ground. When a large population is being supported by a coastal freshwater aquifer and more water is being withdrawn from it than is being replenished, this typically occurs.

Building injection walls that create barrier for instruction should be implemented to mitigate saltwater intrusion.
