Abstract

Loussi polje, located in North Peloponnesus on the SE of Kalavryta village is a very interesting but little studied karst area. Water from karst springs and boreholes that drain the local carbonate aquifers is exclusively used for water supply and irrigation purposes in this scarcely populated area. An attempt to delineate protection zones in karstic aquifers was made, by assessing the groundwater vulnerability to pollution. PRESK, an adaptation of the RISKE groundwater vulnerability method of carbonate aquifers was applied. Modifications were necessary in order to meet with the specificity of Loussi karst terrain. PRESK method takes into account the protective role of topography in combination with vegetation (P factor), the nature of geological formations (R), the presence of epikarst (E), the existence of an overlying soil cover above carbonate aquifers (S) and the degree of karstification of the carbonate formations themselves. Groundwater vulnerability was assessed for both Olonos - Pindos and Tripolis carbonate aquifers of the study area.
