Abstract

Slovene karst sources are of great national importance for drinking water supply. Since karst aquifer systems are very susceptible to contamination, these sources require appropriate and careful managing. Unfortunately, in the acts of Slovene legislation, the special characteristics of water flow within karst regions are not very seriously taken into consideration in determining the criteria for karst water sources protection. In contrast, in some other countries, the concept of groundwater vulnerability mapping has been successfully used for protection zoning and land use planning in karst. Regarding the differences between particular karst aquifer systems, data availability and economic resources, different methods of karst water vulnerability assessment and mapping have already been developed. Already these methods have been many times tested and implemented in different test sites worldwide. However, experience in application using different methodologies for vulnerability mapping of karst aquifers is very modest in Slovenia. The present paper deals with potential methodological problems that might arise while applying the most commonly used methods for karst water vulnerability assessment to Slovene karst regions.
