Abstract
Two new-drilled wells in the Prgovo Polje are pumped and additionally tested for the water supply of the island Lastovo. The research works were aimed at finding boundary quantitative and qualitative parameters for their optimal exploitation, desalination and use of the pumped water in the existent water supply system. Collected hydrogeological and hydrogeochemical data indicate the presence of stratified aquifer in the western part of Prgovo Polje consisting of two poorly connected horizons. Water from the shallower part of the aquifer, drilled by the well MZ-2 in the carbonate rocks at the edge of polje, is good enough for desalination. The deeper part of aquifer, drilled by the well MZ-1 in the carbonate cavern below the polje’s clastic sediments, experiences the greater influence of the sea water. Its continuing pumping combined with low quantity of water is the main reason of the ever increasing influence of the sea water.
