Science and Decisions


Book Description

Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.




Guidelines for Drinking-water Quality


Book Description

This volume describes the methods used in the surveillance of drinking water quality in the light of the special problems of small-community supplies, particularly in developing countries, and outlines the strategies necessary to ensure that surveillance is effective.




Copper in Drinking Water


Book Description

The safety of the nation's drinking water must be maintained to ensure the health of the public. The U.S. Environmental Protection Agency (EPA) is responsible for regulating the levels of substances in the drinking water supply. Copper can leach into drinking water from the pipes in the distribution system, and the allowable levels are regulated by the EPA. The regulation of copper, however, is complicated by the fact that it is both necessary to the normal functioning of the body and toxic to the body at too high a level. The National Research Council was requested to form a committee to review the scientific validity of the EPA's maximum contaminant level goal for copper in drinking water. Copper in Drinking Water outlines the findings of the committee's review. The book provides a review of the toxicity of copper as well as a discussion of the essential nature of this metal. The risks posed by both short-term and long-term exposure to copper are characterized, and the implications for public health are discussed. This book is a valuable reference for individuals involved in the regulation of water supplies and individuals interested in issues surrounding this metal.




Drinking Water Health Advisory


Book Description

Health Advisories (HAs) are prepared by the Criteria and Standards Division, Office of Drinking Water (ODW) of the United States Environmental Protection Agency (USEPA) in Washington, D.C. Documents summarized in this volume are part of the Health Advisory Program sponsored by ODW in response to the public need for guidance during emergency situations involving drinking water contamination. They provide technical guidance to public health officials on health effects, analytical methodologies, and treatment technologies associated with drinking water contamination. The HAs for 15 unregulated volatile organic chemicals were developed jointly by the Environmental Criteria and Assessment Office and ODW. Each HA contains information regarding the nature of adverse health effects associated with the contaminant and contaminant concentrations that would not be anticipated to cause an adverse effect following various periods of exposure. In addition, the HA summarizes information on occurrence, analytical methods, environmental fate, and treatment techniques for the contaminant.




Drinking Water Health Advisory


Book Description

Each Health Advisory gives the useful and relevant data on the health effects associated with each contaminant, and gives concentrations of the contaminant that would not cause adverse health effects during various periods of exposure. Complete sections also cover information on available analytical methods and treatment techniques for the contaminants. This essential technical guide is a must for water treatment plant supervisors, managers and operators. Federal, state, local and public officials who are responsible for drinking water quality and public health in the event of emergency spills or pesticide contamination will value this easy-to-use reference.




Drinking Water Health Advisory


Book Description

The United States Environmental Protection Agency (U.S. EPA) Office of Water (OW) initiated the Health Advisory Program in 1978 to provide information and guidance to individuals or agencies concerned with potential risk from drinking water contaminants for which no national regulations currently exist. Since that time, over 100 Health Advisories (HAs) have been published in final form for inorganic, organic, and microbial contaminants. This volume contains HAs for munitions chemicals developed as part of a Memorandum of Understanding between the U.S. EPA and the Department of the Army. To develop each HA, the authors reviewed toxicological data for each chemical and presented the relevant studies to allow an evaluation of the data without continued reference to the primary documents. Each HA has undergone critical internal review by the OW Toxicology Review Panel, EPA program offices, the EPA Reference Dose (RfD) Committee, the EPA Carcinogen Risk Assessment and Verification Enterprise (CRAVE) Committee, and the Army Medical Department (for munitions chemicals only). Finally, the HAs were reviewed by an external panel of experts in toxicology and risk assessments. Drinking Water Health Advisory: Munitions will be an important reference document for all DOD/DOE hazardous waste sites, drinking water professionals, and academic libraries.







Health Advisories for Drinking Water Contaminants


Book Description

The United States Environmental Protection Agency (EPA) Office of Water (OW) initiated the Health Advisory Program in 1978 to provide information and guidance to individuals or agencies concerned with potential risk from drinking water contaminants for which no national regulations currently exist. Since that time, more than 130 Health Advisories (HAs) have been published in final form for inorganic, organic, and microbial contaminants. The HAs in this volume were developed in a cooperative effort with the Office of Research and Development. They summarize available data concerning the occurrence, pharmacokinetics, and health effects of 12 specific contaminants or mixtures. Each HA also discusses available analytical methods and treatment techniques for the contaminant. Each HA has undergone critical internal review by the OW Toxicology Review Panel and EPA program offices. Health Advisories for Drinking Water Contaminants will be an important reference document for all public health officials, drinking water professionals, and academic libraries.




Safe Drinking Water Act


Book Description

This new book covers drinking water regulations such as disinfectant by-products, synthetic organics, inorganic chemicals, microbiological contaminants, volatile organic chemicals, radionuclides, fluoride, toxicological approaches to setting new national drinking water regulations, and trihalomethanes. In addition, organic and inorganic compounds scheduled to be regulated in 1989 and new candidates for the 1990s regulations are detailed.




Reviews of Environmental Contamination and Toxicology


Book Description

Global attention in scientific, industrial, and governmental commumtIes to traces of toxic chemicals in foodstuffs and in both abiotic. and biotic environ ments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to pro vide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental con tamination and toxicology. Until now there has been no journal or other publica tion series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wildlife, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authoritative publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancil lary legislation.
