Not sure what the technical term is to explain this, buty is there such a thing as a dry or potential aquifer?

A trapped layer of the kind of rocks that often do hold significant amounts of groundwater, but this particular layer doesn’t because the water can’t get to it because it is trapped between two or more impermeable layers? But if water did get to it, say you could drill bore holes and pump water down there, it would function as a perfectly good aquifer.

Does such a beast exist?
Does it have a technical name?

Like a confined aquifer?

Like a confined aquifer?

Yeah. but one that is currently dry because it is isolated from any source of water recharge.

is that possible, or does water always find a way in eventually?

I mean that’s kind of the same as saying it is above the water table right?

I’m not sure if a layer such as that has a specific name other than being called “permeable”.

Confined between two impermeables?

not necessarily, you have nave confined aquifers that exist above the water table.

pp’s question seems to be “is it possible to have a permeable sequence that is completely dry either all of the time, or at least some of the time”. the answer is yes, it’s possible.

it need not be, not all aquifers are “confined”

True but I believe that is what p_p was aking?

To wrap up, if there’s a word for that specific thing, I don’t know it.

Yes, that’s it. I wasn’t sure of the wording.
