ENVIRONMENTAL ISOTOPES STUDY AT A RESEARCH LANDFILL (BREITENAU, LOWER AUSTRIA)

摘要

Understanding of the pollutants transport at a landfill presupposes information about the water movement. With respect to environmental isotopes, the Breitenau Experimental Landfill offers several indicators which facilitate the study of water movement in waste bodies and in the bottom liners. They are in part random (~3H contamination of the leachate by a ~3H source contained in the waste), in part can be attributed to the water used in the construction of the bottom liner, and in part emerge from the landfill itself (strong shift of the ~2H content of the leachate as a result of the anaerobic decomposition). Therefore, infiltrating precipitation water differs clearly in several parameters from leachate.
