Karst Aquifers

Karst aquifers are a special type of fractured rock aquifers (limestone, dolomite or magnesite) in which the water in the fratures has dissolved the relatively soft rock, thereby significantly increasing the size of the fractures. In some places, these solution cavitities can be tens of metres wide and form underground cave systems.

Groundwater flow in karst aquifers is more concentrated and more rapid than in the other aquifer types. Obtaining a successful borehole supply depends on striking a large, well connected solution cavity system.
