THE VULNERABILITY DETERMINATION OF GROUNDWATER BODIES IN SOUTHEASTERN BOSNIA ACCORDING TO DRASTIC, GLA AND EPIK METHODS

Abstract

The vulnerability results of groundwaterbodies of southeastern Bosnia are shown in this paper. On the
examined area 27 groundwater bodies were extracted, where 12 groundwaterbodies are in rocks with
intergranular porosity and 15 groundwaterbodies are in rocks with karst-fissure porosity. All of the
groundwater bodies were analysed through DRASTIC, GLA, PI and EPIK vulnerability determination
methods, where the gained results are presented tabular. Depending on the porosity type, the
vulnerability determination methods were used. So for intergranular groundwaterbodies the best results
were gained by DRASTIC and GLA methods, while for the karst-fissure groundwater bodies the best
results were gained by the EPIK method, which is the implementation of PI method.
