Available in PDF, EPUB and Kindle. Book excerpt: A thorough analysis of public policy and the Clean Water Act'seffect on water quality in the U.S. Using water quality data and historical records from the past 60years, this book presents the measured impact of the 1972 CleanWater Act on domestic waterways-ecologically, politically, andeconomically. Municipal Wastewater Treatment supports thehypothesis that the Act's regulation of wastewater treatmentprocesses at publicly owned treatment works (POTW) and industrialfacilities has achieved significant success. The authors' case ispresented in: * Background information on the history of water pollution controland water quality management * Chapters addressing long-term trends in biochemical oxygen demandloadings from municipal wastewater plants and the "worst-case"dissolved oxygen levels in waterways downstream of point sourcesbefore and after the Clean Water Act * Nine case study assessments of long-term trends of pollutantloading water quality and environmental resources associated withPOTW discharges Using long-term trends in dissolved oxygen as the key indicator ofwater quality improvements, this book provides a detailedretrospective analysis of the effectiveness of the water pollutioncontrol policies and regulations of the 1972 Clean Water Act. Thesuccesses of the Act that have been achieved over the past 30 yearsare placed in the historical context of the "Great SanitaryAwakening" of the 19th century and changes in public policies forwater supply and water pollution control that have evolved duringthe 20th century to protect public health and the intrinsic valueof aquatic resources. Case study sites include the ConnecticutRiver, Hudson-Raritan Estuary, Delaware Estuary, Potomac Estuary,Upper Chattahoochee River, Ohio River, Upper Mississippi River, andWillamette River. Complete with end-of-chapter summaries and conclusions, MunicipalWastewater Treatment: Evaluating Improvements in National WaterQuality is an essential book for engineers, scientists, regulators,and consultants involved in water quality management and wastewatertreatment, as well as students of environmental engineering,environmental science, and public policy.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Available in PDF, EPUB and Kindle. Book excerpt: Water Wells and Boreholes provides the necessary scientificbackground together with practical advice using global casestudies, in an accessible easy to use style suitable for bothpostgraduates/researchers and practitioners. The book begins with an introduction to the type and uses ofwater wells from water supply and irrigation through to groundwaterremediation. It then covers well siting detailing how to sourcedata from geophysical surveys, remote sensing etc. Well design isthen summarised to ensure the well is stable and cost-effective.The book ends with three chapters covering well construction, welltesting and well performance, maintenance and rehabilitation.

Download or read book Biology of the Hard Clam written by J.N. Kraeuter and published by Elsevier. This book was released on 2001-04-26 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hard clam, Mercenaria mercenaria, is an important commercial, recreational and ecological inhabitant of coastal bays along the east and gulf coasts of the United States. This title represents the first state of the art summary of existing knowledge of the hard clam by experts in various disciplines.Containing a compendium of literature on the hard clam, comprehensive chapters on various aspects of its biology as well as summaries of knowledge including the gray literature on this economically important species, this volume represents a comprehensive source of biological information for managers and researchers interested in shallow marine and estuarine ecosystems. Research students and managers charged with maintaining coastal ecosystems will also find a wealth of background material.The first synthesis of available information on the mercenaria mercenaria, this title is a response to the needs of individuals involved in hard clam aquaculture and scientists interested in molluscan biology, coastal ocean ecology and similar fields. Over 2300 documents have been synthesized, and chapter authors have added unpublished information as well as new material.

This book was released on 1997-12-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book follows upon earlier work which culminated in the publication of two recent books, Sustainable Development: Science, Ethics, and Public Policy (John Lemons and Donald A. Brown, editors), and Perspectives on Ecological Integrity (Laura Westra and John Lemons, editors). Both of these books also were published by Kluwer Academic Publishers. In this book, we seek to explore more fully the concepts of sustainability and ecological integrity as well as the connections between them. We have divided chapters into three groups. In the first, the concept of sustainability in relation to science, law, and ethics is explored. In the second, concepts of sustainability and ecological integrity are applied to problems in specific natural resources. Finally, in the third group we examine possible approaches to public policy which might include concepts of sustainability and ecological integrity. Overall, we believe that this collection presents a wide variety of perspectives, discussions, and case studies.
