The paper analyses application of different methods for removal of the high content of ammonia from groundwater sources of the Grocka municipality neighborhoods Umcari and Pudarci. According to the relevant data from this field method, biochemical oxidation with the Nitrosomonas and Nitrobacter bacteria was used. Parameters of biological processes of the ammonia oxidation were defined on the pilot model located at the groundwater source. On the pilot model, consisting of a trickling filter and a fast gravel filter, quantitative oxidation NH4 to NO3 was done. Purification plant was designed with parameters of the pilot model, with minimal investment and exploitation expenses, without undesired side products and ecological risks characteristic for procedure of chemical oxidation of ammonia, which recommends this procedure as the optimal solution.

In the frame of the project Water Supplying of the Cities and Protection of the Groundwater Quality in the Velika Morava Valley, was obtained the analysis of potential polluters of groundwater sources of town Velika Plana - Livade. This paper presents results of water physical, chemical and microbiological characteristics of soil. According to the results of research and way of usage of the soil, it was concluded that agricultural production does not have negative influence on quality of the groundwater source.

Protection of raw water quality at the water source is delicate and often very expensive. As it is known, the majority of hydrotechnical structures are complex and big in both technical and financial terms. This paper is aiming to show necessity to provide, if possible, multipurpose use of these structures in order to reduce and distribute the costs.

This is the presentation of the content of heavy metals (Pb, Cd and Zn) originating from the several representative locations of the natural water springs in the Northern Kosovo and Metohija . For the determination of presence and content of Pb, Cd and Zn in these spring waters the Potentiometric stripping analysis (PSA) method was used as a high-sensitive and selective electroanalytical technique.
