One statement governing these entities, which equates the negative specific weight with the vertical pressure gradient, is the Dupuit assumption.

That law applies to the phreatic type of these structures, contrasted with the "confined" type found in vadose zones. Saline intrusion disrupts human usage of these formations, and arsenic contamination is another problem for the largest of these formations in the United States, named Ogallala. Hydrostatic pressure within permeable rock strata may cause these subterranean structures to form artesian wells. For 10 points, name these porous layers of rock that hold groundwater.
