Groundwater
Spanish
Border

Is the water which is found below the ground level. This water in most cases is derived from filtered water.

It is found in those geological formations which have porosity.

When the water reaches an impermeable layer is built up and forms underground reservoirs called aquifers.

When groundwater runs through limestone rocks, dissolves them and produces a kind of relief called karstic, forming caves with stalactites and stalagmites.
