Lead is a ubiquitous toxic agent that is especially damaging to the young child and the developing fetus. Unlike many environmental health risks, the risks associated with lead are no longer theoretical but have been observed for many years. Indeed, the first regulation of lead in paint was enacted in the 1920s. Currently, because of growing evidence of lead toxicity at lower concentrations, the U.S. Centers for Disease Control and Prevention recently lowered its lead-exposure guideline to 10 ug/dl lead in blood from 25 ug/dl. Measuring Lead Exposure in Infants, Children, and Other Sensitive Populations addresses the public health concern about the logistics and feasibility of lead screening in infants and children at such low concentrations. This book will serve as the basis for all U.S. Public Health Service activities and for all state and local programs in monitoring lead.

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.

Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

The history of a long-running environmental catastrophe chronicles the harmful effects of lead pipes and their continued use despite evidence that they pose a significant health risk. In The Great Lead Water Pipe Disaster, Werner Troesken looks at a long-running environmental and public health catastrophe: 150 years of lead pipes in local water systems and the associated sickness, premature death, political inaction, and social denial. The harmful effects of lead water pipes became apparent almost as soon as cities the world over began to install them. Doctors and scientists noted cases of acute illness and death attributable to lead in public water beginning in the middle of the nineteenth century, and an editorial in the New York Herald called for the city to study the matter after a bizarre illness made headlines in 1868. But officials took no action for many years. New York City, for example, did not take any steps to reduce lead levels in water until 1992, long after the most serious damage had been done. By then, in any case, much of the old lead pipe had been replaced with safer materials. Troesken examines the health effects of lead exposure, analyzing cases from New York City, Boston, and Glasgow and many smaller towns in Massachusetts, New Hampshire, and England. He draws on period accounts, government reports, court decisions, and economic and demographic analysis to document the widespread nature of the problem, the recognized health effects—particularly for pregnant women and young children—and official intransigence. He presents an accessible overview of the old and new science of lead exposure—explaining, for example, why areas with soft water suffered more harmful effects than areas with hard water. And he gives us compelling and vivid accounts of the people and politics involved. The effects of lead in water continue to be felt; many older houses still have lead service pipes. The Great Lead Water Pipe Disaster is essential reading for understanding this past and ongoing public health problem.
