Finalist for the 2021 PROSE Award for Environmental Science! An integrated approach to understanding and mitigating the problem of excess nitrogen Human activities generate large amounts of excess nitrogen, which has dramatically altered the nitrogen cycle. Reactive forms of nitrogen, especially nitrate and ammonia, are particularly detrimental. Given the magnitude of the problem, there is an urgent need for information on reactive nitrogen and its effective management. Nitrogen Overload: Environmental Degradation, Ramifications, and Economic Costs presents an integrated, multidisciplinary review of alterations to the nitrogen cycle over the past century and the wide-ranging consequences of nitrogen-based pollution, especially to aquatic ecosystems and human health. Volume highlights include: Comprehensive background information on the nitrogen cycle Detailed description of anthropogenic nitrogen sources Review of the environmental, economic, and health impacts of nitrogen pollution Recommendations and strategies for reducing humanity's nitrogen footprint Discussion of national nitrogen footprints and worldwide examples of mitigation policies The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

"A research tour de force that seamlessly melds archaeology, geology, ecology, environmental history, and a contemporary conservation ethic. Not only is this volume a must read for scholars interested in Florida’s past, but it is one that deserves to be read by anyone interested in Florida’s threatened environments."—T. R. Kidder, Director of the Washington University in St. Louis Geoarchaeology Lab "O'Donoughue writes thoughtfully and poetically about Florida’s geological history and long-term patterns of environmental change and cultural adaptation. A compelling case for the relevance of archaeology to current environmental concerns."—Christopher B. Rodning, coeditor of Fort San Juan and the Limits of Empire "Examines Florida’s critically important springs and discusses how they were used and modified over thousands of years by local inhabitants, placing the springs in a deep historic context while offering well-informed suggestions for their long-term management and use."—David G. Anderson, coeditor of Archaeology of the Mid-Holocene Southeast Throughout their history, Florida's springs have been gathering places for far-flung peoples. In Water from Stone, Jason O'Donoughue discusses the genesis of springs and their role as sites of habitation, burials, ritualized feasting, and monument building for Florida's earliest peoples. O'Donoughue moves beyond a focus on the ecological roles of springs and the popular image of springs as timeless and pristine--approaches taken by many archaeologists and conservationists. Instead, he foregrounds the social and historical importance of springs and their ongoing use as gathering places that draw people for ritual purposes even today. This archaeological viewpoint creates a bridge between past and present, encouraging conservation efforts that focus on the intrinsic value of springs as places of personal experience and social interaction with deep historical significance. To save the springs, O'Donoughue argues, we must recognize the relevance of the past to the problems Florida's artesian springs face today.

Groundwater quality monitoring and testing is of paramount importance both in the developed and developing world. This book presents a series of papers illustrating the varied nature of current research into groundwater quality. Urban and rural supplies are covered through a case history approach, and the importance of remedial action to prevent deterioration is emphasized.
