29 October Outline Part A: A system for identification and ranking of polluted sites was developed – to prepare remediation action plans for heavily polluted sites in Serbia Part B: Relevance for finding practical solutions for key environmental issues, River Basin Management (RBM) Preparation of risk based and cost-effective remediation plans
29 October Introduction (1) Currently, Serbia is working on: improving environmental protection and water quality protection of water resources aligning its procedures with the EU In Serbia and its riversheds many polluted sites are present These site are potential threat to soil, surface water and groundwater resources Remediation of these polluted sites is needed
29 October Introduction (2) In Serbia national inventories are under development related to; pollution sources accidental risk spots contaminated sites Goal: To improve the conditions for remediation of polluted sites in Serbia Results of this project provided an approach for the entire process from identification of potentially polluted sites to the preparation of remediation plans
5 september A stepwise approach
29 October Phase 1: Identification of sites Identification methods: long-list of 386 sites
29 October Phase 2: Pre-assessment Multi criteria analyses (MCA) was applied for ranking the long-list
29 October Phase 3/4: Re-assessment Site investigations of 10 pre-selected sites Development of additional ranking criteria (MCA) cost level and effectiveness remediation possibility of implementing the remediation Detailed environmental impact assessment (Top-3) baseline study site conceptual model Tier II risk assessment Risk based and cost-effective remediation plans
29 October Part B: Tool for River Basin Management (Dutch case) The Dutch ‘Room for the River’ Programme recognised that insight in presence of polluted sites is needed optimise the measures estimate total (remedial) costs A quick scan was performed: GIS-database of national inventories expert-judgement; estimate remedial costs A GIS-database of polluted sites showed to be a promising tool for (spatial) planning and cost- effective execution of protection measures
29 October Conclusions A practical approach for identification and ranking of polluted sites was developed and successfully applied: Long-list of 386 potentially polluted sites Preparation of risk based and cost-effective remediation plans The project showed that an initial assessment, based on limited input data and professional judgement, can provide within a short time frame a reliable assessment and ranking of polluted sites
29 October Conclusions The developed identification and ranking system has proven to have potential as a tool to support the decision-making process: meet environmental goals prepare environmental protection and remediation plans and programmes estimate budgets optimise spatial planning
