In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

“An important story not just about [Texas’s] water history, but also about its social, economic, and political identity” (Western Historical Quarterly). As a changing climate threatens the whole country with deeper droughts and more furious floods that put ever more people and property at risk, Texas has become a bellwether state for water debates. Will there be enough water for everyone? Is there the will to take the steps necessary to defend ourselves against the sea? Is it in the nature of Americans to adapt to nature in flux? The most comprehensive—and comprehensible—book on contemporary water issues, A Thirsty Land delves deep into the challenges faced not just by Texas but also by the nation, as we struggle to find a way to balance the changing forces of nature with our own ever-expanding needs. Part history, part science, part adventure story, and part travelogue, this book puts a human face on the struggle to master that most precious and capricious of resources, water. Seamus McGraw goes to the taproots, talking to farmers, ranchers, businesspeople, and citizen activists, as well as to politicians and government employees. Their stories provide chilling evidence that Texas—and indeed the nation—is not ready for the next devastating drought, the next catastrophic flood. Ultimately, however, A Thirsty Land delivers hope. This deep dive into one of the most vexing challenges facing Texas and the nation offers glimpses of the way forward in the untapped opportunities that water also presents. “A hard look at a hard problem: finding sufficient water to live in a place without much of it. . . . McGraw’s fine book serves as a useful guide. Observers of Western waterways will want to have this on their shelves alongside the likes of Marc Reisner and Charles Bowden.” —Kirkus Reviews “In stark prose that often gleams like a bone pile bleached in the sun, McGraw travels back and forth across Texas to give a free-ranging but deadeye view of the crisis on the horizon.” —Texas Monthly “It’s hard to write about the slow creep of environmental crises like drought without resorting to shock tactics or getting lost in the weeds . . . [McGraw] draws out the conflicts in compelling ways by drilling into the plight of individual water users. Even if you feel no connection to Texas, these stories are relevant to every part of the country.” —Outside “Interviewing both scientific experts and everyday water users, [McGraw] clearly delineates the competing interests, describes political and geological reality, and makes a compelling argument for statewide water policy that utilizes modern technology and fairly weighs parochial needs against the good of the whole.” —Arizona Daily Star, Southwest Books of the Year

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

In this concise introduction to water resources, Shimon Anisfeld explores the fundamental interactions between humans and water, including drinking, sanitation, irrigation, and power production. The book familiarizes students with the current water crisis and with approaches for managing this essential resource more effectively in a time of rapid environmental and social change. Anisfeld addresses both human and ecological problems, including scarcity, pollution, disease, flooding, conflicts over water, and degradation of aquatic ecosystems. In addition to providing the background necessary to understand each of these problems, the book discusses ways to move towards better management and addresses the key current debates in the water policy field. In the past, water development has often proceeded in a single-sector fashion, with each group of users implementing its own plans without coordination with other groups, resulting in both conflict and inefficiency. Now, Anisfeld writes, the challenge of water management is figuring out how to balance all the different demands for water, from sanitation to energy generation to ecosystem protection. For inquiring students of any level, Water Resources provides a comprehensive one-volume guide to a complex but vital field of study.

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

The relationship between federal and state water pollution policies is revealed and assessed in this incisive volume. Focusing on Congress's statutory directions in the Federal Water Pollution Control Act of 1972 and state compliance, this study throws into relief the complex and often troubled relationship between the laws enacted by Congress and the public policies produced by state governments that implement them. Compliance at the state level can be affected and sometimes disturbed by state politics, particular policymaking processes, and the effects of federal oversight practices. As convincingly demonstrated in these pages, American water pollution policy reflects neither runaway bureaucracies nor Congressional control, but rather a complex intergovernmental process that is structured around Congress's statutory directions.
