Soil contamination can create unacceptable ecological or human health risks. Mapping of contaminated soil sites and the resulting cleanup are time consuming and expensive tasks, requiring extensive amounts of geology, hydrology, chemistry and computer modeling skills. This book reports on one of the largest and most comprehensive risk assessment studies of its kind in North America on chemicals of concern, and what risk management is required to reduce these risks. Written by worldwide experts, this book will be of interest to academics, researchers, policy-makers and consultants working with the next generation of new soil contamination cases. What reviewers say about this book: For consultants: "This volume is not simply a text book; rather it is a detailed case study, offering insights into the scientific decisions made throughout the project. It provides both a historical record of one of the largest studies of its kind, and provides a foundation from which future investigators can learn and plan their own studies. It is highly recommended for anyone dealing with risk For teachers: "This book can be used as a detailed classroom study, providing students with a broad understanding of the myriad steps and decision points of risk assessment, as well as illustrating the use of common risk techniques and tools."
