Principal types of Aquifers

Switzerland is rich in groundwater. Groundwater resources occur almost everywhere, both in unconsolidated rock and fissured or karstified rock. Groundwater is contained in aquifers, i.e. permeable bodies of rock, often with very small cavities (pores), that can store water.
