The phreatic zone, or zone of saturation, is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturated with water.
Its opposite is the unsaturated vadose zone above the water table—aquifer.
The phreatic zone size and depth may fluctuate with changes of season, and during wet and dry periods.

Famous quotes containing the word zone:
“Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash.”
—Louis Aragon (1897–1982)
