Abstract

In 1999 the Dutch government agreed on a new policy regarding the reuse of lightly contaminated soil. From now on, lightly contaminated soil may be reused under conditions of soil-quality management. The municipal authorities supervise the reuse under this new regime. Two basic criteria need to be met before reuse of lightly contaminated soil is allowed. Firstly, the quality of the soil has to be characterised on a soil quality map. Secondly, the soil that will be reused has to be of the same - or better - quality than the topsoil already present. Both criteria require more detailed prescriptions on a national level in order to assure that the principle of 'stand still' is maintained. In a two phased process, a guideline for the preparation of soil quality maps and for the assessment of reusability will be developed. The first phase resulted already in a provisional guideline necessary for effective implementation of the new policy. Some complex problems were not dealt with in the provisional guideline, but will be solved mid 2001. The current second phase will result in a final version of the guideline.
