Porous and permeable rock {aquifer}| can hold water.
Wells {artesian well}| can reach water table.
Soil and rock water {groundwater}| depends on precipitation, evaporation, rock porosity, and soil permeability.
Water-saturated-rock upper-surface level {water table}| is same as nearby lake and pond surface level.
Soil water permeability and movement {infiltration}| is most for sand, middle for loam, and least for clay.
Water infiltration is most for sand, middle for loam, and least for clay {permeability, soil}|.
Below soil, rainwater goes into rock-crystal open spaces {porosity}|, down to 100,000 feet.
