Water Pollution IX


Book Description

Featuring papers from the Ninth International Conference on Water Pollution, this volume covers coastal areas and seas, lakes and rivers, groundwater and aquifer issues, oil spills, agricultural contamination, environmental monitoring and sensing, and remote sensing applications.




Watershed Management for Potable Water Supply


Book Description

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.




Encyclopaedia Britannica


Book Description

This eleventh edition was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time and it is considered to be a landmark encyclopaedia for scholarship and literary style.




Biochemical Ecology of Water Pollution


Book Description

Biochemical ecology is here presented only in the context of water pollution. This is not to minimize the importance of land animals and plants in their environment or the significance of air pollution as it relates to ecology. It merely indicates that water pollution is a problem of sufficiently broad magnitude to warrant consideration by itself. Water pollution is a problem which requires the attention of a variety of disciplines. The presentation tends therefore to follow the problem ap proach, as do most interdisciplinary topics. An appreciation of various viewpoints is needed among chemists, ecologists, economists, engineers, lawyers, limnologists, managers, microbiologists, and politicians, whose communications are often "hung up" in each other's jargon. Perhaps the presentation is too elementary at times. This was done in an attempt to bridge the diverse backgrounds of those concerned with the subject. It is hoped that engineers, economists, biologists, public servants, and others will gain a greater appreciation of the interrelationship of gross observations and biological events that occur at the cellular and molecular level. Lack of such understanding is, to a large extent, the reason for our present environmental condition. At other times the presentation is perhaps too technical. This was done on the assumption that some information on chemical details may not be readily available but is desirable for an "in depth" appreciation of the biochemical events encountered in water pollu tion.

Ninth International Conference on Water Pollution Research


Book Description

Ninth International Conference on Water Pollution Research focuses on the methods, measures, and technologies involved in the treatment of wastewater, including the treatment of sludges and pollutants in bodies of water. The selection first offers information on carbon adsorption as an advanced wastewater treatment process, nitrification of surface water, and methods for measuring the thickenability of sludges. Topics include factors that influence adsorption, principle of biological nitrification, and characterization of sludges. The text also discusses the utilization of pulped newsprint as a conditioning aid in the vacuum filtration of a municipal sludge and the purification of pulp-bleaching wastewater with aluminum oxide. The publication reviews the properties and treatment of lime-algae sludge, concept of filterability, prediction of bacterial pollution in sea water, and the role of retained particles in deep bed filtration. The text also describes the immediate and continuous measurement of activated sludge quantity in sewage biological treatment tanks; comparative assessment of pollution loadings from non-point sources in urban land use; and wastewater control technology in steam-electric power plants. The book is a vital reference for readers interested in water pollution research.




Water Pollution XII


Book Description

Water Pollution XII contains the proceedings of the 12th International Conference in the series of Modelling, Monitoring and Management of Water Pollution. The book will be of interest to scientists, managers and academics from different areas of water contamination. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies required the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential. Topics covered include: Water quality; Groundwater and aquifer issues; Environmental monitoring and control; Water management; Remediation; Pollution prevention; Lakes and rivers; Agricultural contamination; Wastewater treatment and management; Offshore pollution and oil spills; Emerging technologies; Biosensors and biosystems; Health risk studies; Modelling and simulation; Pharmaceutical and pesticides pollution; Monitoring and modelling integration; Risk assessments; Socio-economic-political consequences; Education and training.







Water Quality for Ecosystem and Human Health


Book Description

This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.
