Global change and in particular population growth and climate variability are increasing the pressure on groundwater resources. An assessment and prediction of this impact on groundwater quantity and quality is not possible without a proper monitoring of groundwater change. Groundwater is monitored in many parts of the world but there is still no systematic monitoring of global groundwater resources.

Until recently, aquifers located in hard rock formations (granite, gneiss, schist) were considered as a highly heterogeneous media, and no adequate methodology for groundwater management was available. Recent research studies showed that when hard-rocks are exposed to regional and deep weathering processes and when the geology is relatively homogeneous, a typical hard rock aquifer is made of two main superimposed hydro-geological layers each characterized by quite homogeneous specific hydrodynamic properties: namely the saprolite and the fissured layers. Therefore, for these cases, hard rock aquifers can be considered as a multi-layered system.
