Why can't you put submarines in underground acquifiers and explore them? Why can't people dive in them? Why can't I find any images of them?
There is far more groundwater in the world than above ground freshwater. Many civilisations rely on wells to give them all their water needs. So why can't you go underground and actually swim in the source of this water? It would likely be pitch black of course, but that would be rectified using lights.

Go back to school, or use google, or use brains.

I'm studying Earth science and the truth of the matter is we can. But they've got to be really really really really tiny. Really tiny.
I would say that the most common rock for an aquifer is sandstone. Between the grains of sand are spaces which can be infiltrated with water. If the pore spaces between mineral grains are too cemented together water can't infiltrate. We call that rock high porosity, low permeability. There are of course other aquifers than simply ones with highly porous mineral grains. Rock can have cracks which water can seep into which can create an aquifer that way.
If you want to 'dive' into something underground containing water we would no longer call that an aquifer. We call that an underground river and those do exist but by definition they are no longer aquifers.

I hope you don't seriously believe that there's a layer of earth on top of an enormous lake.
I'm not sure if I should be angry at you for being dumb, or angry at the publishers of that textbook for being misleading.

People don't explore underwater rivers because they're a fucking deathtrap. It's so easy to get stuck or lost and then you're fucking dead, especially with the risk of rapids and vortexes and other weird water flows inside the river/cave. Usually they're too small for a vehicle to get into, too.
And that's just referring the the extremely large underwater rivers that a human could fit into. Most are just tiny cracks between grains of sand

They certainly do
