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.

This book analyzes the theory of ecological engineering of human settlements and provides case studies on the improvement of degraded lands and vegetation restoration, especially focusing on saline-alkali land, abandoned land, water source areas, and the impact of green belts on noise and air quality on the highways. In addition, it discusses the issue of biodiversity conservation strategies in rural landscape construction and demonstrates experiment measurement and field survey methods. The results obtained are supplemented by numerical calculations, presented in the form of tables and figures. As the first monograph on this subject, the book provides a wealth of ideas and resources for researchers, professionals and practitioners in the field of human settlements.

In April 1992 the Foundation Eni Enrico Mattei organized a workshop on the regulation of nonpoint source pollution. This volume inc1udes the proceedings of that meeting, as well as additional original contributions, in an attempt to provide an overview of recent theoretical developments in the field. Research on the causes, consequences, and control of nonpoint source pol lution has been carried out over the last two decades. Interest in this subject has grown as a result of the increasing recognition of the insufficiency of traditional pollution control policies focused on the large scale, confined, and general ly predictable pollutant discharges. In fact, many contemporary problems are caused by the combined activities of small polluters, along with natural pro cesses, intermittent and unpredictable events, and often involve pollutants with complex environmental outcomes. Despite the progress made in understanding the nature and size of pollution from diffuse sources, the issue of regulation is still far from being system at ically and adequately addressed. This policy vacuum is partly attributable to the difficulty of adapting the traditional point source regulatory tool kit to the specific features of nonpoint source problems. Such features inc1ude the tech nical difficulty of identifying sources and measuring individual emissions, their variability over time and space, the role played by natural processes in detennin ing pollutant discharges at source and their ultimate impacts on the receiving environmental media.

Marine Ecotoxicology: Current Knowledge and Future Issues is the first unified resource to cover issues related to contamination, responses, and testing techniques of saltwater from a toxicological perspective. With its unprecedented focus on marine environments and logical chapter progression, this book is useful to graduate students, ecotoxicologists, risk assessors, and regulators involved or interested in marine waters. As human interaction with these environments increases, understanding of the pollutants and toxins introduced into the oceans becomes ever more critical, and this book builds a foundation of knowledge to assist scientists in studying, monitoring, and making decisions that affect both marine environments and human health. A team of world renowned experts provide detailed analyses of the most common contaminants in marine environments and explain the design and purpose of toxicity testing methods, while exploring the future of ecotoxicology studies in relation to the world's oceans. As the threat of increasing pollution in marine environments becomes an ever more tangible reality, Marine Ecotoxicology offers insights and guidance to mitigate that threat. - Provides practical tools and methods for assessing and monitoring the accumulation and effects of contaminants in marine environments - Unites world renowned experts in marine ecotoxicology to deliver thorough and diverse perspectives - Builds the foundation required for risk assessors and regulators to adequately assess and monitor the impact of pollution in marine environments - Offers helpful insights and guidance to graduate students, ecotoxicologists, risk assessors, and regulators interested in mitigating threats to marine waters
