This book provides practising engineers with a firm basis on which to classify types of derelict land and alert them to the range of environmental and legal considerations involved.The book examines the hazards involved in land recycling, from geotechnical and hydro-geological, to chemical and biological. The need for an integrated approach to site investigation is emphasized, showing the interaction between physical, chemical and biological aspects of a particular site. Data from case studies are used to illustrate analysis and interpretation procedures.
