The present paper is dealing with the analysis and characteristics of the discontinuous media, represented by the ophiolite nappe in central Euboea (Mantoudi). It is aiming at the conception, the development and the subsequent validation of an integrated methodology for the description of fissured rocks, in the frame of intrinsic vulnerability assessment and mapping. The vulnerability is not being considered as a characteristic of a particular element at risk, but as a peculiarity of a complex territorial system, in which the different elements are reciprocally linked in a functional way. In order to estimate and to define both the quality and quantity, a group of parameters are being considered. The estimation and definition of those parameters are based on the geoenvironmental conditions of an area that may be vulnerable to contamination, in order to distinguish the geological, geomorphologic and hydrogeological criteria that affect the environmental impact of hard rock aquifers. These criteria are being calibrated in GIS so as to be able to support a correct territorial planning and a suitable management of the water resources protecting its quality which is essential to increase efficient use of existing water supplies. Furthermore, a sensitivity analysis has been performed to evaluate the influence of single parameters on aquifer vulnerability assessment.
