Water table groundwater diagram. The upper level of this saturated layer of an unconfined aquifer is called the water table or phreatic surface. Diy water well drilling results off grid cabin build 28 duration. An areas water table is the level beneath the surface where water saturated soil and rock is found. If the liquid is less dense than water it will float on top of the water table like oil on water. Above the level of the water table is unsaturated soil even though that soil is damp it also contains air. Light non aqueous phase liquids lnapls.

It is located up to a depth of 4 kms of the earths surface table 41. The unsaturated zone above the water table the gray area still contains water after all plants roots live in this area but it is not totally saturated with water. Substances seep into groundwater faster than they can dissolve some of the contaminants will stay in liquid form.

The water moves from an area where water enters the aquifer a recharge zone to an area where water exits the aquifer a discharge zone. Groundwater may be near the earths surface or as deep as 30000 feet according to the us. Substrate with low porosity that permits limited transmission of groundwater is known as an aquitard. It is an irregular boundary that separates the unsaturated zone and the underlying zone of saturation. If the liquid is more dense than. Pollutants in this form are called.
