The Blato aquifer is situated on the western side of the island of Korčula, southern Dalmatia, Croatia. The terrain is built of karstified carbonate rocks, mostly of the Cretaceous age. In the Blatsko karst polje there are four water supply wells with a total yield of about 60 l/s. The catchment area is 28 km2. The whole terrain is tectonically disturbed and compressed ; the most permeable fracture system is perpendicular to the structural "b" axes, which gives rise to a general groundwater direction towards the island's northern coast. Average precipitation is 850 mm/year, but when there is less than 700 mm/year there is a high possibility of sea water intrusion during the summer season. The risk significantly increases when dry years repeat. Hydrochemical research has shown that two main pollution sources occur at different hydrological moments: sea water intrusion happens in the dry summer period when there is maximal extraction and almost no recharge ; and the washing of nitrates and other humanly caused pollution indicators from the soil and epikarst belt during the rainy season. All factors must be taken into account when planning management and protection of such a sensitive environment.
