ANTHROPOL.PROT - Study of anthropogenic pollution after the war and establishing of measures for protection of Plitvice National Park and Bihac region at the border area of Croatia and Bosnia-Herzegovina
The objective of the project was the assessment of anthropogenic pollution after the war events and its consequences to the karst ecosystem in a border zone between Croatia and Bosnia-Herzegovina promoting the scientific-technical co-operation between these countries and some Member Countries of the European Union. The activities were focused on the hydrogeologically connected areas of the Plitvice Lakes National Park and neighboring karstic fields from the Croatian side, and the Una River catchment area in the Bihać region, Bosnia and Herzegovina. The project was oriented towards the end users: local authorities, enterprises, national parks and non-governmental organizations in the area. Therefore three specific case studies were chosen: on a tourist domain, a municipality domain and an industry domain.
Data collected by partners within the project, as well as physico-chemical and isotopic analyses of samples collected during three years of the project, served as a background for elaborating a hydrogeological model and further modeling of intrinsic vulnerability, hazard and risk assessment of surface and groundwater resources in the area of transboundary aquifers. All these data, as well as the results of previous studies, were incorporated into the Geographic Information System (GIS) and visualized and modeled through the ArcMap-ArcView software.
The case study performed on the tourist domain was directed to investigation of human influence to the area of Plitvice Lakes National Park. These investigations showed that the concentration of trace elements, as well as of organic matter, was mainly of natural origin. This conclusion can calm the park administration and local authorities, because they have been concerned about the influence of tourist activities and dense traffic connecting interior of Croatia with its littoral. The only indicator of pollution was shown by detergent-derived chemicals caused by the defects in the sewerage system from the hotels situated above Lake Kozjak in the last decades. Since recently the whole system was repaired, new measurements of the uppermost sediment layer should be done in the near future in order to see if these measures helped in reducing of detergent-derived chemicals.
The case studies performed on the municipality and industry domains were focused to the Una River catchment area in the Bihać region, Bosnia and Herzegovina, and to the springs used for water supply of this region. Since this region was practically isolated from the outer world during the war 1992, many illegal waste deposits were formed, which — together with the possible pollutants coming from the abandoned military and industrial facilities could have hazardous impact on the water quality. The measurements showed that the major pollutants in the river water are ammonia, nitrites and phosphates. However, the main springs in the Bihać area satisfy current regulations for public drinking waters. Groundwater flow dynamics, residence times, recharge rates and mixing between hydraulically connected aquifers from both countries, essential for the protection of water, were also studied by using natural and anthropogenic trace substances (isotopes).
On the basis of investigations performed during the period 2003-2005 we suggested several rehabilitation measures, primarily to the Bihać area, which suffered much during the war activities, like the inauguration of the continual monitoring of surface and groundwater, protection projects for water-supplying springs, making the land-register of pollutants and improvement of purification of waste waters from industrial facilities. Further dyeing experiments in order to determinate the transboundary hydrodynamic characteristics and protection zones should be made. In the Plitvice Lakes National Park the control of the sewerage system should be continued. The record of possible anthropogenic influence to the lakes could be made by future monitoring of pollutants in the uppermost layers of lake sediment.
