Sažetak
The northern part of Istria in the border region between Croatia and Slovenia is a typically karst area. Water flow is for the most part underground and feeds karst springs, which are an important source of drinking water for Istria County in Croatia and Slovenia’s Primorska region. The main water supply systems include the Sv. Ivan and Bulaž springs on the Croatian side and the Rižana spring on the Slovenian side. A common characteristic of these springs is that they have catchment areas that extend across the national borders. The karst aquifer in their catchment areas is recharged by a complex system that includes both direct infiltration of precipitation on the karst surface and sinking streams that flow from the surface into ponors. Underground flow is rapid and covers considerable distances, following routes which are for the most part unknown. Pollution also spreads rapidly with the water, which represents a threat to water sources. As a result of the characteristics described above, karst aquifers are extremely vulnerable to the consequences of various sources of pollution. Successful protection is possible if we are familiar with the characteristics of their functioning. For this reason, hydrogeological research is the foundation of planning of the protection of karst water sources and optimisation of their use.
