The United States may not be able to make all hazardous-waste sites as clean as possible. Therefore, priorities must be set for the timing of waste site remediations. This book assesses several of the government's methods of ranking sites for remediation and compares the performance of three such models using input data developed from the same set of waste sites. Because inconsistent methods may be neither effective nor prudent, the book recommends that the government consider developing a unified national approach to setting priorities to replace the current multiple approaches.

Hazardous Waste Risk Assessment provides a concise yet comprehensive examination of concepts and techniques in risk assessment that can be applied to hazardous waste problems. The book emphasizes the use of health risk assessment to support management decisions on hazardous waste disposal and site remediation programs. Methods discussed include those for developing strategies for health and environmental assessment and site restoration tasks, evaluating corrective action programs, determining the effects of risk assessment results on risk management decisions in hazardous waste programs and general risk management and prevention programs, and performing safety evaluations of hazardous waste facilities. Step-by-step numerical case evaluations are used to help present the book in an easy-to-follow, realistic manner. Features

The majority of chapters in this volume are devoted to various aspects of health risk assessment the evaluation of health hazard associated with human risk exposure to environmental chemicals. Among topics discussed

Hazardous Waste Site Remediation is an outstanding textbook that reviews specific treatment processes, as well as pertinent basic concepts in organic geochemistry, material balance mass transfer, thermodynamics, and kinetics. Following a quantitative approach to source control, the text covers regulations, materials handling, engineering principles, soil vapor extraction, chemical extraction and soil washing, solidification and stabilization, and chemical destruction. It also explores topics in bioremediation, thermal processes, risk assessment, and waste minimization. A solutions manual is available.
