Conclusions

• Site development of contaminated properties is
  commonly used in Denmark
• Investigations and remedial actions are arranged
  with the authorities
• Especially properties located by waterfronts are
  attractive
• Possible building technical steps are established
  (membranes etc.)
• Slightly contaminated soil can be used for baffle
  walls or modeling of parking areas.
• The experiences from Denmark can be used in
  Lithuania.
