New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

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.

Long taken for granted, water resources are rapidly becoming a contentious issue within American politics. Continuing population growth and rapid development, coupled with environmental events such as droughts, have led to increasing water shortages in sections of the nation. In Interstate Water Compacts author Joseph F. Zimmerman highlights the growing importance of water issues within the United States and a device that has been instrumental in facilitating interstate cooperation to solve water-related problems: the interstate compact. This groundbreaking work is the first to devote itself exclusively to interstate and federal-interstate compacts pertaining to controversies including the abatement of water pollution, apportionment of river waters, economic development, flood control, inland fisheries, marine fisheries, and restoration to rivers of anadromous fish, such as salmon and shad. The process for entering into interstate and federal-interstate compacts is explained in detail, as is the exercise of original jurisdiction by the US Supreme Court to resolve intractable interstate controversies involving interpretation of provisions of compacts, water apportionment, and water pollution abatement. Zimmerman concludes by calling for the President, Congress, governors, state legislatures, and local governments to devote more attention and resources to finding solutions for water-related problems.
