If toxic spills occur, chemicals move vertically through the zone of aeration and may penetrate the zone of saturation or ground water. The zone of aeration is also referred to as the unsaturated zone.Above the zone of capillary saturation are two zones that are only partly saturated; together they define the zone of aeration. The lowermost zone is characterized by semicontinuous capillary saturation while the uppermost zone is characterized by discontinuous capillary saturation. In both of the latter zones, the materials will yield no water ...
