In this study, an overview is presented of agricultural policies on manure and minerals, relating to the Nitrate Directive to remedy excessive surface- and groundwater contamination from intensive agricultural practices.

In situ remediation techniques have experienced a boom over the last few years, thereby producing a wide range of valuable experiences. Their results have demonstrated that in situ techniques are a mature alternative to conventional remediation techniques.

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.

In situ remediation techniques have experienced a boom over the last few years, thereby producing a wide range of valuable experiences. Their results have demonstrated that in situ techniques are a mature alternative to conventional remediation techniques. Irrespective of future policy developments, it is impossible to imagine future remediation practice without the use of in situ techniques. The book presents an overview of recent developments in the field of in situ soil remediation. The book is unique in that it is not a compilation of unrelated case studies. A conceptual approach has been chosen; remediation models described in this book are illustrated from a practical point of view. The authors present the Dutch way of treating contaminated land; The Netherlands is renowned for being at the forefront of remediation techniques as a result of the country's progressiveness and experience in this area.
