aquifer

Palestinians are only allowed to dig wells 150 meters deep, but Israelis dig to the aquifer.

In west-central Kansas, up to a fifth of the irrigated farmland along a 100-mile swath of the aquifer has already gone dry.

I frequently refer to the Ogallala Aquifer, which is the largest in the High Plains system.

Vast stretches of Texas farmland lying over the aquifer no longer support irrigation.

Refilling the aquifer would require hundreds, if not thousands, of years of rains.

The aquifer dips toward the region of the wells from higher ground, where it outcrops and receives its water.

Which will supply the larger region with artesian wells, an aquifer whose dip is steep or one whose dip is gentle?

And we know just what the strata formations are both below the reservoir and in the aquifer downstream.
