Having known the fact that on the territory of West-Backa region the only water used for water supply system is subterranean water, from different water layers, an assumption can be made that the waters also differ in their physical and chemical content. It is also assumed that these waters differ in their total iron content. The aim of this work is to test the significance of the difference between central water supply systems of West-Backa region (Sombor, Apatin, Kula and Odzaci) for the value of iron in drinking water, using the adequate statistics methods. The central water supply systems in Sombor, Apatin, and Kula are using water from the second water layer (60-75 m), while the water supply system in Odzaci is using deep artesian and subartesian waters (146-220 m). Sombor and Apatin have the raw water purification system and one of the goals is to decrease the concentration of total amount of iron in drinking water.

Author described the beginnning of organized supply Zajecar, Serbia (Serbia&Montenegro) with drinking water and the establishment of Public Firm for Water Supply. In this paper author shows the results of five-years analysis of drinking water and the influence of water quality on human health during this period of organized supply with water.

Nis Tobacco Factory, Serbia (Serbia&Montenegro) has water supply from two resources, public water supply system and from its dug well. In periods of water shortages and smaller deliveries from public water supply system (e.g. recession periods) it is necessary to provide additional water quantities for proper functioning of tobacco refinement. For that purpose capability for utilization of terrace deposits for water supply was analyzed.

The fenced hunting area "Crni Lug" near Progar (Serbia, Serbia&Montenegro), included swamp tracts that have been drying. A natural environment of free game has changed over the last fifteen years. The unfavourable hydrological trend is explained by the antropogenic factor active in the hunting area and beyond it. The prevailing hydrogeological situation is interpreted and steps for rehabilitation of marshes are recommended. One of the emphsized goals is the supply of good water for animals throughout the year. Favourable hydrogeology and construction of adequate facilities in the hunting area will suffice for the revival of all activities related to water: flood control, agriculture, water supply, and hunting as a particularly profitable activity.

Forest ecosystems are important component of environment and row basis for wood processing industry. Traditional attitude about primate of productive functions in relation to useful functions, is under question, due to next reasons: exhaustion of sources of wood mass; affirmation of protective and regulative functions in domains of water-supply and erosion control. This attitide os represented in basic plan documents in Serbia, as well as in European Union. Protection, care of existing, and restoration of degraded forests, are the possibilities for development of high-profitable activities such as: recreation and sport tourism, hunting tourism and healthy food production.
