3. BUWALOFEFPUFAFPSAEFL Why cooperation? Why cooperation? BUWALOFEFPUFAFPSAEFL Uncertainties about contaminations are hindering sustainable development increasing pressure on greenfield sites a severe burden on public and industry purse International cooperation and coordination is needed in order to avoid duplication of research and to provide a wider basis for scientific peer review to generate focused and transparent approaches to the problem which are economically viable

4. BUWALOFEFPUFAFPSAEFL Key question Key question BUWALOFEFPUFAFPSAEFL How to reduce the cost of dealing with land contamination without compromising public health and environmental conditions, or business confidence in the benefits of land regeneration and sustainable use of soil and land ?

5. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land The Ad Hoc International Working Group on Contaminated Land is an informal forum for international exchange and co-operation. Its principal purpose is to provide a forum, open to any country, in which issues and problems of contaminated land and ground- water can be discussed and information freely exchanged to the benefit of all participants.

6. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Participants / Contributors: „Regulators“: those concerned by contaminated land issues within national ministries and environ- mental agencies Frequency of meetings: A plenary meeting takes place every second year Organisers / Host of the meetings: One country holds the secretariat for 2 years and thereafter hosts the next meeting Actual situation: Switzerland = Host / Canada = Secretariat

7. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Topics discussed at the Copenhagen Meeting, 1999 Groundwater protection strategies Diffuse contaminations Contaminated Land in Central and Eastern Europe Management of Contaminated Land (Details: Report of the Copenhagen Meeting, 1999, SAEFL 2000)

8. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Topics to be discussed at the Geneva Meeting (17 & 18 september, 2001) Persistant pollutants sites, or: where natural attenuation comes to an end Sustainable remediation of contaminated sites Groundwater: fit for use or clean? Limits of the polluter pays principle Contaminated sites and safety installations Contamination resulting from oil production

9. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Persistant pollutants sites, or: where natural attenuation comes to an end Is there a comprehensive definition of a „Persistent pollutants site“? Size of the problem (number of PEPSI‘s) Conceptual differenciation necessary between contaminations resulting from heavy metals and from organic substances? Maximum acceptable time-span for natural attenuation?

10. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Sustainable remediation of contaminated sites Has everything to be cleaned-up by our generation? Methods to establish ranking of priority sites: Decision framework based on type of relevant pollutants, type of risks to humans and the environment, liability and financial means of polluters, necessary timeframe for natural attenuation, costs for long-term monitoring and maintenace of technical systems, etc.

11. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Groundwater - fit for use or clean? Drop multifunctionality for use dependant remediation goals? Policies, strategies, attitude towards natural attenuation Point of compliance? Substances that need to be regulated Approaches towards residual contaminations Protection of aquifers for future use

12. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Limits of the polluter pays principle Discussion of the following situations Polluter does not exist any more or is bankrupt Polluter = Public (local dumps, landfills, etc.) Polluter is a state owned entity or enterprise (e.g. army, state owned mines, etc.) Polluter is a neighbouring country (e.g. pollution of rivers, groundwater, shorelines by activities in neighbouring countries)

13. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Contaminated sites and safety of installations Co-operation between issues related to conta- minated sites and to the safety of installations Integration of clean-up costs in safety considerations Sufficient liability limits for long-term effects EU white paper helpful? Consideration of possible transboundary impacts

14. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Contamination resulting from oil production: from the bore-hole through the refinery to the end-user Size and importance of the problem Are the present problems addressed in an environmentally appropriate manner? Additional measures to be taken in the future

15. BUWALOFEFPUFAFPSAEFL Ad Hoc Int‘l Working Group on Contaminated Land Invitation: Members of governmental institutions are invited to participate at the next plenary meeting of the Ad Hoc International WorkingGroup on Contaminated Land in Geneva, Switzerland 17 and 18 September 2001 For more information please contact: Urs Ziegler, Switzerland (urs.ziegler@buwal.admin.ch) or Adrien Pilon, Canada (adrian.pilon@nrc.ca)

16. BUWALOFEFPUFAFPSAEFL CARACAS & CLARINET CARACAS & CLARINET are European concerted actions on contaminated land initiated within the EC Environment and Climate Programme. CARACAS (1996 - 1998) Risk Assessment CLARINET (1998 - 2001) Risk Management Partnership between 16 European countries combinig the knwoledge of various stakeholders such as regulators, academia, consultants, landowners & developers of technologies

17. BUWALOFEFPUFAFPSAEFL CLARINET CLARINET = Contaminated Land Rehabilitation Network for Environmental Technologies in Europe Objectives are to identify the means by which management of contaminated land can be applied according to the principles of sustainable development to ensure the safe (re-use) of such land to abate water pollution caused to maintain the functionality of soil and (ground-) water ecosystems and to coordinate related RTD activities in the EU
