ABSTRACT
More than one third of the people in the world currently depend on groundwater as a water resource. According to the global distribution of groundwater dependency ( UNESCO-IHP, 2008), the dependence on groundwater is greater in the arid and semi-arid regions where the availability of surface water is low. This is not exceptional even for developed countries, such as the EU region with groundwater dependency of 65% (EU, 2000). The level of dependence on groundwater can be higher in the sectors such as agriculture with non-point water use. In contrast to sectors such as metropolises and industries where concentrated and focused intensive water use (point water use) is needed with the use of surface water playing a comparatively central role.
