Reni water-wells near Novi Sad (Yugoslavia) are built on the Danube, and the greater part of the water is filtered from the Danube which affects the quality of the water in the water in the wells. The filter layer through which the river water goes to the wells has both mechanical barrier and catalyst role in the microbiological oxidoreductive processes. As for the physical and chemical aspects, the filter layer on the banks contains only polar particles. This is why the removal of all microcontamination from water cannot be expected. The result of the analysis the Danube water preparation in the fluoridized layer of granulated biologically active coal indicates that in the aerobe and unaerobe reactors there is a microbiological process, similar to that in the filter layer in the banks. The content of organic matter is decreasing, the same is with potentially harmful bacteriae, coliform ones are completely disappearing, the number of the heterotrophs is increasing to a certain degree, and then a decrease of the number is expected. During the preparation, the non-polar and weakly polar microcontaminations and pesticides are totally removed. All the same, certain quantities of the most polar remain in the water, and it is possible to remove them by polar adsorbents in a compound with active coal.
