However, the air demand requirements for mixing should still be compared with the air demands for oxygen transfer across all of the zones of an aeration tank to ensure that sufficientThe zone of aeration consists of the upper layers of soil in which there is air-filled porosity, pores or pockets filled with air rather than water. If toxic spills occur, chemicals move vertically through the zone of aeration and may penetrate the zone of saturation or ground water.

1. In the zone of aeration, some of the pore space is occupied by air, and some of the pore space is occupied by water. In the zone of saturation, all of the pore space is occupied by water. 2. It's easier for water to flow through large pores because there's less friction between the flowing water and the pore walls.

In order to be successful, a well must be drilled into the zone of saturation. The velocity at which water flows underground depends on the permeability of the rock or how large and well connected the openings are.

Water seeps through the zone of aeration to the zone of saturation where openings in soil and rock are completely filled with water. The top of the zone of saturation is called the water table. Where the water table intersects the ground surface, springs and streams form. Note that the depth of the water table varies with the topography.
