  3. like that? What is Switzerland?

  4. it’s also like that! Chromium VI-Emissions! hundred thousands of tons of chemical waste! Brownfields! What is Switzerland?

  7. Persistant polluted site / PEPSI • Kölliken Landfill site = PEPSI site • High percentage of persistant pollutants • Persistant pollutants well dispersed, not extractable • (in-situ measures not applicable) • Degradation & lixiviation of pollutants >>> 50 years • Substantial danger exists over long periods • (up to x00 years)

  8. Remediation strategy • For the Kölliken site decontamination is indicated • Decontamination is the only solution for a • long-term successfully and economically remediation • In 2003 the authorities decreed the complete excavation • of the landfill by 2012. • Decontamination costs: 350 Mio. $ (excavation and • off-site treatment) • Containment methods would have very high consumer • costs for the long-term operation over hundreds of years: • - Containment costs to date: 100 Mio. $ • - Annual treatment/monitoring costs: 4 Mio. $
