Aquifer | Types &Amp; Facts | Britannica

Aquifer | Types &Amp; Facts | Britannica

In many aquifers, groundwater levels have fallen drastically in recent times. This is commonly due to the diversion of aboveground water sources as well as to excessive groundwater mining for irrigation and other uses. Such depletion increases pumping costs, causes wells and rivers to dry up, and, where a coastal aquifer is in hydraulic contact with seawater, can cause the intrusion of saline ...

Radioactive Waste From Uranium Mining And Milling ...

Industries in the United States recover uranium from the Earth through mining or chemical extraction. Mining: When uranium is near the surface, miners dig the rock out of open pits. Open pit mining strips away the topsoil and rock that lie above the uranium ore. When uranium is found deep underground, miners must dig underground mines to reach it.

Mining: Making The Most Of Radioactive Caches

Mining: Making The Most Of Radioactive Caches

Mining methods depend on the type of deposit, whether it's suspended in water and the geography of the area. For instance, if miners find a deposit sandwiched between layers of rock and water, in-situ recovery will be a more cost-effective option. If experts deal with dry ore, they'll most likely stick with a type of open-pit or underground mining.
