Here's a breakdown:

* Groundwater: Water that seeps into the ground and is stored in underground layers of rock and soil called aquifers.

* Wells: Holes drilled into the ground that tap into aquifers, allowing water to be pumped to the surface.

* Springs: Natural points where groundwater flows out to the surface, often where an aquifer intersects the ground surface or where a layer of impermeable rock forces the water upward.

So, the source of water for both wells and springs is the same: groundwater stored in underground aquifers.
