Part I - Groundwater background 1-1 How does the zone of saturation differ from the zone of aeration? And, what is meant by water table? Zone of saturation is the area below where soil moisture peculates downward till it reaches the zone where all spaces in sediment rock are completely filled. The zone of aeration is the are above the water table where the oil rock and sediment are not saturated. Water Table is the upper area zone of saturation. 1-2 Why does groundwater move? 1-3 What type of rocks make the best aquifers? b Permeable rocks such as sands and gravels make the best aquifers. 1-4 What is meant by drawdown and cone of depression? Use a simple sketch to illustrate.
