Possibilities of soil clean‐up. Abandoned hazardous sites are abandoned waste sites or industrial sites which threaten human health, the environment, or other aspects of public safety. The enforcement of clean‐up of abandoned hazardous sites lies with the Federal German States. Registration and evaluation programmes are underway. Up to now nearly 50 000 suspected sites are registered in the former States of the Federal Republic of Germany and nearly 28 000 in the new states. Calculations of more than 100 000 suspected sites have been made. Several techniques are available for clean‐up which had been funded within the framework of numerous R&D‐programmes. The clean‐up technologies operating in praxis include thermal treatment, physico‐chemical treatment (soil washing and soil venting), and biological treatment. Future trends focus on combined treatment technologies in soil treatment centers.
