<jats:title>Abstract</jats:title><jats:p><jats:bold>Technologies for the clean‐up of soil contamination and older burdens</jats:bold>. Older burdens as a consequence of fast industrialization and soil contamination by leakage and accidents require fast clean‐up. Sealing measures and storage on disposal sites postpone solution of the problem to some day in the future. Thermal treatment and washing entail extensive earth‐moving operations. They have a high energy requirement and are expensive. Microbiological processes presently under development are expected to yield less expensive solutions. The degradation properties of soil microflora or specially cultured microorganisms are exploited for this purpose. Treatment of lower‐lying contamination requires an adequate oxygen supply at the site of action.</jats:p>
