Abstract Agriculture and water sources protection zones Petra Oppeltová MENDELU, Zemdlská 1,Brno, 613 00, Czech Republic. E-mail: oppeltova@mendelu.cz The question of contamination and protection of water source is a theme of great importance. Most drinking water is obtained from surface and ground water resources in the Czech Republic. For drinking water quality and quantity protection, it is necessary to establish protection zones. The area of interest is located in the South Moravia Region at the confluence of Jihlava, Oslava and Rokytná rivers. Ivanice spring area comprises a series of hydrologic boreholes - it is the main water source for water supply of Ivanice and Rosice cities and provides water for 30 000 inhabitants. The risk analysis was created on the basis of water quality monitoring, hydrogeological assessment and terrain exploration and revision of protection zones was proposed. The spring area is situated in nitrate vulnerable zones and recently nitrate concentrations have been decreasing. Water quality evaluation results: high concentration of manganese and iron, sometimes higher concentration of ammonium and COD. This area is intensively used for agriculture and it was necessary to make a compromise solution during protection zones proposal. The regime in protections zones can’t affect manganese and iron concentration (their origin is in the natural geological environment). Therefore, water treatment plant is in operation and its modernization is proposed. Further the paper deals with spring area intensification – construction of new hydrologic borehole and managed and unmanaged infiltration of surface water. The proposal of protection zones revision consists of reduction to 2nd level protection zone. Key words: water quality, ground water source of drinking water, good agricultural practice, nitrate vulnerable zones, Czech Republic 1. Introduction 1.1. European and Czech legislation There have been numerous changes regarding legislative framework for water during the last years. One of the reasons for these changes was the Czech Republic entering the European Union in 2004. The most important European Directives transposed to the national legislation are: Directive 2000/60/EC and Directive 91/676/EC. Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy (Water Framework Directive). By this Water Framework Directive, the European Union organizes management of surface water, continental water, transitional waters, coastal waters and groundwater in order to prevent and reduce its pollution, promote sustainable water use, protect and enhance the status of aquatic ecosystems and reduce the effects of floods and droughts (http://www.directivamarco.es/). Its fundamental principles are: • hygrographic basin as the management unit which corresponds to the unit with natural hydrological cycle. • cost recovery in the price of water that includes externalities. • achievement of good eco-biological, hydromorphological and physical-quimical status. • water and aquatic ecosystems recovery as a best guarantee of water quantity and quality – ecological aspect for sustainable water use.
