abstract of the article published in Danubius 1-2/1998

The paper has review of the quality of surface flows of the Danube, Sava and Velika Morava rivers. There are many significant sources of ground water in their riparian areas. The quality of those aquifers may be jeopardized by the surface waters of mentioned rivers if the untreated waters are directly disposed to their flows. That is why this paper has the analyses of conditions and possibilities of the ground water protection on the basis of the experimental test on pollution transportation.

Ground waters in alluvial aquifer deserve the main consideration for municipal water supply in the Republic of Serbia. Alluvial aquifer are the principal resources for municipal water supplies of the largest Serbian towns, such as Belgrade, Novi Sad, and many other. Sources of ground waters for these towns are located in riparian areas of major rivers: the Danube, the Sava, and the Velika Morava, where communication of surface and ground flows is continuous, and hence most likely for ground water to be affected by waste waters discharged into the rivers. Foremostly industrial effluents, unless preliminary treated, can easily infiltrate alluvial aquifer through porous gravel's and sands between the rivers and the aquifers. In consequence, heavy metals, organic matter, phenols, fats, fatty acids, synthetic detergents, and the like find their way into ground water.

Quality of the surface water has been tested at 160 points of rivers in Serbia. The analyzed water was satisfactory only in 15 points. Most of the rivers were classified into water quality classes III or IV, few into class II, and none to class I. In all other sampling points, river water either intermittently or permanently was beyond the limits of the River Categorization Regulation of the Republic of Serbia.
