Download or read book Diffuse Pollution written by N. Campbell and published by IWA Publishing. This book was released on 2005-02-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffuse (non-point source) pollution is increasingly being recognised as a major source of water quality problems in both surface and ground water. Indeed, as pollution resulting from point sources is reduced by the efforts of regulators, diffuse sources frequently remain as the dominant source of pollution. The book is an introductory text covering the nature, causes and the significance of diffuse pollution of both urban and rural origin. Best management practices to tackle the problems are examined as are the ways in which the adoption of such practices may be brought about. Use is made of case studies from several countries to examine the strengths and weaknesses of various approaches. Diffuse Pollution covers both urban and rural sources. Urban sources include run-off from impermeable surfaces of roads, industrial areas and housing which may be contaminated by hydrocarbons, heavy metals, organic chemicals and other undesirable substances. Rural sources include water containing pollutants arising from agriculture and forestry such as plant nutrients, pesticides, microbes and soil itself. This concise book will prove useful to practitioners in the field of pollution control both in an urban and a rural environment, to regulators, to researchers new to the field, and to academics and students. An extensive reference section aids the reader in exploring the subject further.

Download or read book Protecting our water soil and air written by Great Britain: Department for Environment, Food and Rural Affairs and published by Stationery Office. This book was released on 2009-02-24 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This code (CoGAP) consolidates and updates the former three separate codes for water, soil and air. The publication offers practical interpretation of legislation and provides good advice on best practice; 'good agricultural practice' means a practice that minimises the risk of causing pollution while protecting natural resources and allowing economic agriculture to continue. It has been written by technical specialists from Defra and Natural England. All farm staff and contractors on the farm who handle, store, use, spread or dispose of any substances that could pollute water, soil or air should be aware of their responsibilities and know about the causes and results of pollution. They should know how and when to operate and maintain the equipment they use, and know what to do in an emergency. The CoGAP provides an important point of reference, based around the main operations that farmers, growers and land managers might undertake; the advice covers activities carried out in the field, but also management plans, farm infrastructure and waste management.

This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The EU Water Framework Directive written by P. Chave and published by IWA Publishing. This book was released on 2001-09-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking over 10 years to develop, the new EU Water Framework Directive is the most significant legal instrument in the water field to emerge from Brussels for some time and will have a profound effect on how water is managed in Europe over the next 25 years. The book outlines its basic features. It explains how the current approach to water management will have to change in order that European Member states and those countries currently in accession negotiations can meet the requirements of the directive, describing a number of examples of current practices as possible systems which could be used in the new approach. The concept of river basin management is outlined, and the potential institutional problems associated with implementing such a system are discussed including the problems associated with cross-border river basins, a common situation in Europe. Examples of existing river basin authorities and international collaboration are given as possible models. The directive requires the establishment of programmes of measures to improve water status. Some countries already use such a concept, and examples are quoted. As a result of its implementation, the directive aims to achieve good water status in all natural surface waters and groundwater in 15 years. For surface waters, the definition of 'good' is based on a new concept of 'ecological quality' taking into account biology, chemistry and their physical features. For groundwater, it includes quantitative status. The approach taken is an integrated one which has to consider all the naturally occurring and human factors which affect the waters. The difficulties of interpretation of the new concept of 'ecological water status' are discussed and some of the examples of current biological and chemical classification schemes that are used in Europe are examined. The directive also alters the way in which pollution is to be controlled - the 'combined' approach. This concept is explained. The EU Water Framework Directive: An Introduction is an invaluable source of guidance on the implementation of the Water Framework Directive for all those concerned with water management including water quality planners and scientists, pollution control and environmental staff in the water and wastewater industries and environmental regulators who all have to adapt to the new approach to their work.
