The protection of karst waters.
A comprehensive Slovene Approach to vulnerability and contamination risk mapping
"A general approach for karst water vulnerability and contamination risk assessment has been proposed, taking into account the special characteristics of Slovene karst landscapes, suiting Slovene environmental legislation and enabling comparison across European countries. The so-called Slovene Approach has been developed on the basis of work accomplished by the European COST Action 620. It incorporates the strongly modified COP method for intrinsic vulnerability assessment by integrating temporal hydrological variability, offering a new possibility to combine surface and groundwater protection, as well as by adapting it to source vulnerability mapping. The methodology provides also comprehensive risk analyses based on the intrinsic vulnerability, hazard and (re)source importance assessments. The proposed Slovene Approach has been first applied to the Podstenjšek water source catchment. Different other methods have been applied (EPIK, PI, COP, Simplified method) and compared. For the catchment area delineation, application of different vulnerability and risk methods a holistic research of the test site has been done by means of tracer tests, detail structural-lithological and geomorphological mapping, electrical resistivity imaging, as well as detail hazard mapping. Continuous monitoring of the springs’ physico-chemical characteristics has been performed for the hydrograph analyses, water balance calculation and aquifer behaviour comprehension. The resulting Slovene Approach intrinsic vulnerability, hazard and risk maps are justified and validation with tracer tests has proved the method to give plausible results. The resulting maps provide improved source protection zones determination and identification of land mismanagement, as well as reorganisation and better practices for future planning."
