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
Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.
Love Canal. Exxon Valdez. Times Beach. Sacramento River Spill. Amoco Cadiz. Seveso. Every area of the world has been affected by improper waste disposal and chemical spills. Common hazardous waste sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills. These sites poison the land and contaminate groundwater and drinking water. A sequel to the bestselling Ecological Risk Assessment, Ecological Risk Assessment for Contaminated Sites focuses on how to perform ecological risk assessments for Superfund sites and locations contaminated by improper disposal of wastes, or chemical spills. It integrates the authors' extensive experience in assessing ecological risks at U.S. government sites with techniques and examples from assessments performed by others. Conducting an ecological risk assessment on a contaminated site provides the information needed to make decisions concerning site remediation. The first rule of good risk assessment is "don't do anything stupid". With the practical preparation you get from Ecological Risk Assessment for Contaminated Sites you won't.
Hazardous waste in the environment is one of the most difficult challenges facing our society. The purpose of this book is to provide a background of the many aspects of hazardous waste, from its sources to its consequences, focusing on the risks posed to human health and the environment. It explains the legislation and regulations surrounding hazardous waste; however, the scope of the book is much broader, discussing agents that are released into the environment that might not be classified as hazardous waste under the regulatory system, but nonetheless pose substantial hazards to human health and the environment. It provides a background of some of the major generators of hazardous wastes, explains the pathways by which humans and wildlife are exposed, and includes discussion of the adverse health effects linked to these pollutants. It provides numerous case studies of hazardous waste mismanagement that have led to disastrous consequences, and highlights the deficiencies in science and regulation that have allowed the public to be subjected to myriad potentially hazardous agents. Finally, it provides a discussion of measures that will need to be taken to control society's hazardous waste problem. This book was designed to appeal to a wide range of audiences, including students, professionals, and general readers interested in the topic. - Provides information about sources of and health risks posed by hazardous waste - Explains the legislation and regulations surrounding hazardous waste - Includes numerous case studies of mismanagement, highlights deficiencies in science and regulation and discusses measures to tackle society's hazardous waste problems
The fiscal and technological limitations associated with cleaning up hazardous waste sites to background conditions have prompted responsible parties to turn to risk-based methods for environmental rememdiation. Environmental Cleanup at Navy Facilities reviews and critiques risk-based methods, including those developed by the U.S. Environmental Protection Agency and the American Society of Testing and Materials. These critiques lead to the identification of eleven criteria that must be part of any risk-based methodology adopted by the Navy, a responsible party with a large number of complex and heavily contaminated waste sites.

The Department of Toxic Substances Control (DTSC) of the State of California Environmental Protection Agency is in the process of complying with the Regulatory Structure Update. The Regulatory Structure Update is a comprehensive review and refocusing of California's system for identifying and regulating management of hazardous wastes. As part of this effort, the DTSC proposes to change its current waste classification system that categorizes wastes as hazardous or nonhazardous based on their toxicity. Under the proposed system there would be two risk-based thresholds rather than the single toxicity threshold currently used to distinguish between the wastes. Wastes that contain specific chemicals at concentrations that exceed the upper threshold will be designated as hazardous; those below the lower threshold will be nonhazardous; and those with chemical concentrations between the two thresholds will be "special" wastes and subject to variances for management and disposal. The proposed DTSC system combines toxicity information with short or long-term exposure information to determine the risks associated with the chemicals. Under section 57004 of the California Health and Safety Code, the scientific basis of the proposed waste classification system is subject to external scientific peer review by the National Academy of Sciences, the University of California, or other similar institution of higher learning or group of scientists. This report addresses that regulatory requirement.
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.
Site-specific risk assessment is the process of evaluating whether or not a site poses a risk to human health or the environment. The purpose of all hazardous waste site remediation is ultimately to render a site safe for human or ecological populations. Consequently, risk assessment, as the process used to measure the effectiveness of the remediation process, is critical to all hazardous waste-site work.Risk assessment at hazardous waste sites involves the use of standard approaches and assumptions in a reasoned, common sense manner. The purpose of this book is to provide practical guidance to people wishing to learn about, conduct, or use risk assessment procedures in evaluating hazardous waste sites. Critical issues, standard formulas and assumptions, and guidance on characterizing risk results in a useable manner are presented. The use of risk assessment as a key tool in selecting appropriate remedial options at hazardous waste sites is also described. Most attention is given to human health risks associated with exposure to toxic chemicals, but descriptions of the strategies used to estimate radiation health risks and to evaluate risks to the environment are also provided. Although most commonly applied to hazardous waste site remediation, the procedures outlined in this book are generally applicable to any situation involving a potential for health risks to an exposed population.This book provides guidance on the mechanics of risk assessment preparation and illustrates these approaches with examples. However, the focus of the book is on the subjective nature of risk assessment, the art rather than the science.The actual risk (i.e., the right answer) can never be known. Consequently, while it is valuable to attempt to obtain the best numeric solution, reasonableness and the application of common sense are equally important. The book therefore devotes a substantial amount of space to issues of uncertainty that are inherent in risk assessment, and the need to address this uncertainty.
