Air flow is established by pumping from vadose zone wells through which contaminant vapors are collected and transported above ground where they are treated, if required, and discharged to the atmosphere.Unsaturated zone: This zone lies immediately between the land surface and above the water table. It is known as the unsaturated zone (or zone of aeration, or the vadose zone) because while this zone is moist, it is not fully saturated with ground water. Water in the soil of the unsaturated zone is referred to as soil moisture.Zone of Aeration. The zone of aeration is commonly referred to as the root zone.
