Subsurface water: water, which is located under the surface in saturated zone and has direct contact with soil or subsoil.
Aquifer layers: subsurface stone layer or stone layers from other geological formations. Their perviousness water permeability renders significant flowing of subsurface water possible or exploits meaningful quantity of subsurface waters.
Subsurface water body: it is a part of subsurface water which is surrounded by aquifers. Subsurface waters form hidden but remarkably important part of water circulation. Those areas, which geological structures are good, are suitable for storing subsurface waters. Quantity, environmental and use-value of subsurface waters in certain regions have outstanding importance. Huge thickness of basin sediments and karst formation of mountains ensure excellent water output from under the surface. Using their advantageous conditions exploitation of subsurface waters is expressive.
Types of subsurface waters
We classify subsurface waters on the basis of their plutonic position compare to stone layers:
Water is essential factor of life on Earth.
Without water there is no life and it has crucial importance for humans:
from point of hygiene, health care, and production
