26 Lecture 9. Introducing the Three Case Studies and Site Visits The third day in the training program is the site visits day. Three landfill sites will be visited to see three leachate treatment technologies: Advanced treatment system at Costa Brava landfill site Chemical treatment system at Namaah landfill site Evaporation lagoon at Bar Elias landfill site If time would allow, Zahle landfill site will be visited to see an evaporation lagoon in-operation. Arrangements have been made to invite the local consultants who designed, or who have been involved in the leachate treatment projects, to present and discuss with the participants their design features and approach.

27 Lecture 10. Lessons Learned: Open Discussions The purpose of this session is to discuss the lessons learned during the first three days of the leachate management training program with special focus on the site visits.

28 Lecture 11. Environmental Assessment of Leachate Treatment Projects What is the Environmental Assessment? Identification of the problem Evaluation of alternative solutions Identification and evaluation of alternative design concepts in the selection of a preferred design concept Preparation and submission of a Project File for public and government agency review Implementation of the preferred alternative and monitoring of any impacts
