A. Rorsch TNO Board of Management In 1985 the Netherlands Organization for Applied Scientific Research TNO, in cooperation with the Netherlands Ministry for Housing, Physical Planning and the Environment, took the initiative for a conference on an important environmental problem: contaminated soil and groundwater. We named it, somewhat self-assured, the First International TNO Conference on Contaminated Soil. And indeed the contamination of soils and groundwater proved to be an environmental issue of such an extent that soon after the successful first conference, TNO started preparations for a second one, this time in cooperation with the State Ministry for the Environment (Umweltbehorde) of Hamburg. And now we are on the brink of the third conference, organized together with the Karlsruhe Nuclear Research Centre (Kernforschungszentrum Karlsruhe). We feel honoured that the Federal Ministry for Research and Technology (BMFT) is again generously supporting this conference, and has anew declared it a BMFT Status Seminar. The conference (generally referred to as Contaminated Soil '85, Contaminated Soil '88 and Contaminated Soil '90, respectively) has successively gained in importance and prestige, which is reflected by the increasing number of participants and contributions to the scientific programme.

This standard work on contaminated site management covers the whole chain of steps involved in dealing with contaminated sites, from site investigation to remediation. An important focus throughout the book is on Risk Assessment. In addition, the book includes chapters on characterisation of natural and urban soils, bioavailability, natural attenuation, policy and stakeholder viewpoints and Brownfields. Typically, the book includes in-depth theories on soil contamination, along with offering possibilities for practical applications. More than sixty of the world’s top experts from Europe, the USA, Australia and Canada have contributed to this book. The twenty-five chapters in this book offer relevant information for experienced scientists, students, consultants and regulators, as well as for ‘new players’ in contaminated site management

F. Arendt, XxX (Conference chairman) w. Harder, TNO (Conference co-chairman) The 1993 Berlin conference on contaminated sites is the fourth in a series of meetings initiated by the Netherlands Organization of Applied Scientific Research (TNO) in 1985 and later continued with the Karlsruhe Nuclear Research center (KfK) of Germany. The present economic stagnation or recession in many countries is leading to various proposals to reduce the level of costly environmental activities: restricted funds are used for really urgent cases rather than precautionary measures. The level of soil contamination caused by the former centrally planned economies adds to this tendency. The Conference tries to broach this controversy by discussing once more the targets and strategies of soil remediation with follow-up use of the site as an important parameter. Both new regulations and modifications of existing lists for a tolerable level of contamination are reviewed alike. Immobilization and enclosure of pollutants are often less expensive than complete remediat ion and, consequently, may grow in significance. We consider the conference of great significance for demonstrating the experiences gained with management and remediation of contaminated sites internationally, among others to avoid mistakes and excessive costs. Two new types of soil contamination became apparent after the end of the cold war. Many military sites, airfields and train ing grorinds are being abandoned. After decades of use, large sections and hot spots of these sites are polluted to a high average level.
