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

3
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

4
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
A stepwise approach
6
Phase 1 Identification of sites

• Identification methods

long-list of 386 sites
7
Phase 2 Pre-assessment

• Multi criteria analyses (MCA) was applied for
  ranking the long-list

8
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

9
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

10
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

11
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
