Subterranean water

The subterranean water indicates all water being under the surface of the ground in the zone of saturation and in direct contact with the ground or the basement.

It exists in three forms:

Boiler feed water

It is the water which returns in the crystalline structure of the minerals (example: Gypsum CaSO4, 2:00 2O)

Absorbed water

The dipolar water molecules are attracted by effects of surface on units ionized (like clays) in fine layer. The water of adsorption is not driven out by centrifugation.
  • ; The water of adhesion (pellicular)
Water is retained on the surface of the grains by an electric attraction less strong than in adsorption, it can move.
  • ; Capillary water
It is in the pores, it is the water of Absorption (the water sought by the roots).

Interstitial water

It is the water of gravity, water available for the Ground water and the Aquifère S, and which is thus available and exploitable, by a Forage or a well.
