Groundwater Governance in Serbia by Prof. Dr Milan Dimkić, Dušan Djurić, Miodrag Milovanović Jaroslav Černi Institute for the Development of Water Resources Belgrade, Serbia Danube River Basin Surface area: 800,000 km2 Population: 80,000,000 About 95% of Serbia’s territory falls within the Danube River Basin. Serbia is a relatively rich in groundwater reserves, deposited in different aquifer systems unequally distributed along the territory. The major groundwater reserves are accumulated in thick Quaternary and Neogene intergranular aquifers. Alluvial aquifers of large rivers (the Danube, Sava, Velika Morava and Drina) are particularly important and widely used for drinking water supply. Karstic aquifers dominate in south-western and eastern regions of Serbia. 1. Bačka and Banat region (comprising N and E parts of Pannonian basin); 2. Srem, Mačva and Sava/Tamnava region (SW Pannonian basin and NW Dinarides); 3. Southwestern Serbia (SW Dinarides), 4. Western Serbia (W Dinarides), 5. Central Serbia (Serbo-Macedonian massif and Shumadia-Kopaonik-Kosovo zone), and 6. Eastern Serbia (Dachian basin and Carpathian-Balkan arch) Groundwater Governance problems Serbia is country in transition. Legal system is in a process of harmonization with EU legislation GDP cca 4000 Euros/capita 1.Problem with institutional capacities on all levels (national, regional, local). 2.Inadequate monitoring 3.Financial problems (drinking water tariff is about 0,5 Euros/m3) 4.Problems with GW quantities in northern part of Serbia 5.Local problems with GW quality (Morava valley). Groundwater monitoring – quantity and quality Groundwater quantity is being systematically monitored by State Hydrometeorological Service and groundwater quantity by SEPA Sanitary control of the water quality for drinking purpose is under responsibility of Ministry of Health and Republic Institute for Public Health and its regional offices. All waterworks аre also controlling basic chemical and bacteriological quality of raw and treated water samples. Groundwater use in Serbia Water supply from different groundwater types 0,1 18,1 Alluvial aquifers Main water-bearing aquifer, Lower Quarter 8,8 Neogene 56 Karstic 17 Fissured Roughly 90% of the population of Serbia has access to the public water supply, and some 75% of water for public water supply is abstracted from groundwater resources. In some areas, currently tapped resources are unable to quantitatively meet the population’s water demand, and there are some problems with drinking water quality, particularly in the northern part of Serbia, due to the lack of treatment. Groundwater is also used for irrigation, water supply of industry, etc. but in lesser quantities. Serbian groundwater legislation The ministry in charge of groundwater governance is the Ministry of Agriculture, Forestry and Water Management, but some responsibilities also lie within the Ministry of Natural Resources, Mining and Spatial Planning, the Ministry of Energy, Development and Environmental Protection, and some other ministries. The most important act dealing with groundwater is the Water Law. By its entering into force in 2010, the governmental policy recognized groundwater issues and their specifics in a proper way. Major tasks on the implementation of the Water Law are related to the protection of groundwater sources, the maintenance and upgrading of existing sources, and the development of new sources. Water Law (adopting principles of WFD) introduces water management planning, through preparation of the documents, including: 1. The Water Management Strategy for the territory of the Republic of Serbia; 2. The Water Management Plans; 3. The annual Water Management Program; etc, IMPLEMENTATION OF THE WFD Serbia became a full member of the ICPDR in 2003. Since then, Serbia is actively engaged in the implementation of: The Danube River Basin District Management Plan (DRBMP 2009), the RBMPs for sub-basins of the Tisza River (finished in 2010) and the Sava River (2012). By adopting the Water Act in 2010, Serbia accepted standards, terminology and goals declared by the WFD. Set of bylaws has been prepared, among them the Code on designation of surface water and groundwater bodies (Official Gazette of the RoS 96/10). 153 groundwater bodies (GWB’s) have been identified in the Serbia. Quantitative status Chemical status Recently conducted or ongoing projects In recent years several large projects for groundwater assessment and protection have been initiated or conducted in order to improve the status and standards of the national water sector and establish a series of general criteria. These activities include: study of aerobic-anaerobic conditions in major alluvial aquifer systems, study of well ageing at numerous alluvial water sources, study that will help establish a new national groundwater monitoring network, surveys for the development of new water supply sources, optimization of artificial recharge for wider application in practice, management of major transboundary aquifers, assessment of the potential impact of climate change, etc. Study of aerobic-anaerobic conditions in alluvial aquifer systems Effect of bank filtration on Belgrade Groundwater Source DOC reduction River water DOC = 2.5 mg/l Raw well water DOC = 1 mg/l Median concentrations of detected pharmaceutical in Danube River and its associated wells along the river bank near town Kovin (Source: Institute for the Development of Water Resources “Jaroslav Černi” 2012.) 10 Study of well ageing at numerous alluvial water sources LHR – local hydraulic resistance KLHR – kinetics of local hydraulic resistance B – biological agent Γ – geometry of aquifer grains and screen openings S LHR f Eh,, Fe Ventr ,, B ventr.

Water for Sustainable Development and Adaptation to Climate Change New UNESCO Category II Center established at the "Jaroslav Cerni" Institute for the Development of Water Resources, Belgrade, Serbia, with aim to: foster scientific coordination and exchange of information among different organizations involved in sustainable water resources management and the development of adaptation strategies due to climate and social changes; disseminate, generate and provide scientific and technical information on water resources management issues; evaluate implications of global change and develop adaptation strategies through the design of new indicators; promote development of regional research programs; undertake effective capacity-building activities. .
