1 IMPLEMENTATION OF PILOT PROGRAMME OF ACTIONS FOR REDUCING POLLUTION OF DRINKING WATER WITH CHEMICAL POLLUTANTS IN THE PUBLIC SYSTEM OF DRINKING WATER SUPPLY MARIBOR, FOR THE PERIOD NEEDS AND EXPECTATIONS Mag. Venčeslav Lapajne* and colleagues from the project team Zavod za zdravstveno varstvo Maribor Prvomajska 1, 2000 Maribor 1 BASIC INFORMATION Development 2007 based on more years imission monitoring programme Municipality of Maribor (MOM) Focus Control of mass flow selected chemicals (pollutants) Dravsko polje On monitoring the quality and loads groundwater, surface water and soil protection areas (VVO) areas that may affect the situation on VVO 2 1

2 BASIC INFORMATION Assessment data from monitoring programme MOM data from programmes national level ground water, surface water, soil, drinking water data from local level drinking water programme of internal control of water supply system 3 PROJECT TEAM Zavod za zdravstveno varstvo Maribor, Prvomajska ulica 1, 2000 MARIBOR Inštitut za ekološki inženiring, Ljubljanska 9, 2000 Maribor Kmetijsko gozdarska zbornica Slovenije, Kmetijsko gozdarski zavod Maribor, Vinarska ul. 14, 2000 Maribor JOANNEUM RESEARCH Forschungsgesellschaft mbh, Institute of Water Resources Management, Elisabethstraße 16/II,8010 Graz Univerza v Mariboru, Filozofska fakulteta, Oddelek za geografijo, Koroška cesta 160, 2000 Maribor Pristop Consensus, komunikacije za odgovorno družbo, d.o.o., Trubarjeva cesta 77, 1000 Ljubljana 4 2

3 STRUCTURE Evidence of pressures, assessment of their impact on the situation of ground water Measures to reduce the impact of key pressures Socio - economic analysis Tools RECONSTRUCTION OF PROJECT Decrees on the water protection zone for the aquifers - into force seven areas Decree on the water protection zone for the aquifers of Ruše, Vrbanski plato, Limbuška dobrava in Dravsko polje (Oj. RS No. 24/2007) Implementation the Decrees an important influence on obligations of stakeholders on responsibilities of stakeholders Indirectly/directly related to the situation in the drinking water supply 6 3

4 2008 ADDITIONAL REASONS Implementation of the Regulations Response of residents (including farmers) FOCUS ON DOBROVCE Reasons Agricultural land located northwest of the water sources of Dobrovce The structure of farming of different kind from dominant cattle to mixed farming Heterogeneous social structure use of different socio - economic scenarios Loads of groundwater Trends With nitrate - upward regardless of the fact absolute levels around 50 mg / l NO3 Presence of pesticides around 0.1 to 0.2 ug/l for each compound. 8 4

7 DOBROVCI_BOHOVA FINALIZING OF THE PILOT PROGRAMME DRAVA II Emphasis to monitor the implementation of regulations defining the criteria to VVO on national and local level Definition of chemical and biological indicators to evaluate the effectiveness of implementation of decrees Definition of risk assessment methodologies drinking water 14 7

8 2010 FINALIZING OF THE PILOT PROGRAMME DRAVA II Scenarios reconstructing of farming non reconstructing of framing preserve traditional farming under controlled conditions Education and informing stakeholders involved in the scheme of public drinking water supply 15 CONCLUSIONS Pilot programme Drava II during the period substantive changes to adapt to changes in the regulations taking into account the socio economic situations on VVO regions Acceptable socio economic situation one of the keys to a successful and sustainable implementation of all measures of sustainable management of water space 16 8

9 KEY RESULTS OF THE PILOT PROGRAMME General rationalization of the widespread expectations of (expected) positive changes in groundwater and drinking loads of water after the implementation of decrees Permanent work with stakeholders vertical and horizontal levels of the Slovenian society Cross-border cooperation and exchange of experience key to management of the situation in a wider geographic area 17 KEY RESULTS OF THE PILOT PROGRAMME Careful and systematic planning of monitoring programs does not mean the impoverishment of programmes evidence of ability of pragmatic way of thinking Integration of modeling modern approach to streamline the monitoring programs management of trends and unforeseen situations 18 9
