Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
Aquifers are found underground.
Aquifers lose their porosity and thus making it not aquifers anymore.
Wells tap into aquifers.
Permeable materials that act as aquifers.
there are exactly 273 aquifers in the world.
Aquifers are made of permeable rock layers
Wetlands contribute to the refilling of aquifers
49% of the area of Germany has porous aquifers, partly with high yields. About 12% is made of fractured aquifers and some 6% karst aquifers. Approximately one-third of the country has only local aquifers with low potential.
Aquifers are groundwater.
