Dzherelo, a common soorce o drinkin watter in a Ukrainian veelage.

Groundwater is the watter locatit beneath the yird's surface in soil pore spaces an in the fracturs o rock furmations. A unit o rock or an unconsolidatit deposit is cried an aquifer when it can yield a uisable quantity o watter. The depth at which soil pore spaces or fracturs an voids in rock acome completely saturatit wi watter is cried the watter table. Grundwatter is recharged frae, an eventually flaes tae, the surface naiturally; naitural discharge eften occurs at springs an seeps, an can furm oases or wetlands. Grundwatter is an aa eften widrawn for agricultural, municipal an industrial uise bi constructin an operatin extraction wells. The study o the distribution an movement o grundwatter is hydrogeology, an aa cried grundwatter hydrology.

Typically, grundwatter is thoucht o as liquid watter flawin through shallae aquifers, but technically it can an aa include soil moistur, permafrost (frozen soil), immobile watter in very law permeability bedrock, an deep geothermal or ile furmation watter. Grundwatter is hypothesized tae provide lubrication that can possibly influence the movement o faults. It is likely that much o the Yird's subsurface contains some watter, which mey be mixed wi ither fluids in some instances. Grundwatter mey nae be confined anly tae the Yird. The formation o some o the landforms observed on Maurs mey hae been influenced bi grundwatter. Thare is an aa evidence that liquid watter mey an aa exist in the subsurface o Jupiter's muin Europa.[1]
