A comprehensive reference on state-of-the-art risk assessment methodologies for drinking water Risk Assessment for Chemicals in Drinking Water discusses the major steps and goals in risk assessments and suggests ways to improve the methodologies and accuracy, while consolidating up-to-date information on the current principles and practices in one authoritative reference. After an enlightening overview of risk assessment practices and regulatory guidelines, it: Includes descriptions of the use of variability analysis, exposure analysis, physiologically based pharmacokinetics, and modeling for both cancer and non-cancer endpoints Describes the practices of major organizations, including the U.S. EPA, Health Canada, World Health Organization, and California Office of Environmental Health Hazard Assessment Includes complete chapters on risk assessment for essential nutrients, arsenic, chloroform, and perchlorate Explains how to address susceptible sub-populations, including the elderly and infants and children, in risk assessments Covers the potential of using genomic and proteomic screens Addresses recent advances, emerging issues, and future challenges With contributions and perspectives from leading scientists, this is the definitive resource for health and environmental scientists, toxicologists, risk assessors and managers, regulators, consultants, and other professionals responsible for the safety of drinking water.

"Water is a molecular marvel. Its seemingly simple formula - H2O -dictates the properties that make water essential for life and easily contaminated. Herein lies the paradox of water-we cannot live without it, but it is easily rendered "unsafe." The Paradox of Water explores the intersection of the scientific, social, and policy implications around access to safe drinking water. Drinking water is the smallest fraction of water used by a nation, yet, access to safe drinking water supports educational opportunities, helps overcome gender inequities, lowers familial stress, and enables more socially and economically productive uses of time"--

Is there potential for a U.S. regulatory system that is more efficient and effective? Or is the future likely to involve 'paralysis by analysis'? Improving Regulation considers the challenges faced by the regulatory system as society and technology change, and our knowledge about the effects of our activities on human and planetary health becomes more sophisticated. While considering the difficulty in linking regulatory design and performance, Improving Regulation makes the case for empowering regulatory analysis. Studying applications as diverse as fire protection, air and water pollution, and genetics, its contributors examine the strategies of different stakeholders in today's complex policymaking environment. With a focus on the behavior of institutions and people, they consider the impact that organizational politics, science, technology, and performance have on regulation. They explore the role of technology in creating and reducing uncertainty, the costs of control, the potential involvement of previously unregulated sectors, and the contentious public debates about fairness and participation in regulatory policy. Arguing that the success of many regulations depends upon their acceptance by the public, Fischbeck, Farrow, and their contributors offer extensive, inductive evidence on the art of regulatory analysis. The resulting book provides 'real world' examples of regulation, and a demonstration of how to synthesize analytical skills with a knowledge of physical and social processes.
