Book excerpt: This state of the environment (SOE) report is a companion volume to the federal science assessment entitled "Nutrients and their impact on the Canadian enviornment", which was authored by Patricia Chambers, et al. This state of the environment (SOE) report on nutrients looks at how the Canadian environment is being affected by nitrogen and phosphorus compounds that are released as a result of human activities. The report describes the mechanisms by which nutrients affect the environment, assesses their impact on the environment especially through enrichment, and their potential for future damage, and outlines the major sources of these compounds. It also looks at what has been done and what can be done to alleviate these problems.

Available in PDF, EPUB and Kindle. Book excerpt: La pollution hydrique est un problème d'actualité, qui se pose notamment dans les zones de forte occupation humaine et d'activités économiques. Son coût est dans certains cas exorbitant vu ses effets néfastes sur la qualité et la quantité des ressources ainsi que sur l'état sanitaire de la population affectés. En Algérie la pollution nitrique devienne de plus en plus préoccupante et prend des dimensions parfois alarmantes. En se basant sur l'analyse de ce cas, le livre présent contribue sur l'évaluation du niveau de contamination nitrique des eaux de puits consommées par une population enquètée et l'identification des principales causes de cette contamination à travers le questionnaire et les analyses microbiologiques. Les résultats obtenus ont montré que 67 % des puits prélevés présentent un taux en nitrates dépassant la norme qui est de 50 mg/L avec une concentration maximale observée de 103 ± 1.41. L'analyse bactériologique a révélé l'existence de coliformes fécaux dans 17 % de puits. Les facteurs de la contamination des eaux de puits investigués et les résultats de l'enquète sanitaire de la population sont discutés.

Download or read book Étude spatiotemporelle de la qualité de l'eau souterraine sur l'aire d'alimentation d'un captage municipal en milieu agricole written by Alexandre Bonton and published by . This book was released on 2010 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'élaboration de stratégies efficaces de protection des captages d'eau souterraine adaptées à un milieu rural nécessite une bonne compréhension des liens entre la qualité de l'eau captée et les activités agricoles menées à proximité de ces captages. Il est toutefois difficile d'évaluer l'impact de modifications de pratiques agricoles ou les résultats de la gestion du territoire sur l'aire d'alimentation d'un captage municipal. Afin d'apporter des éléments de réponse face à ce constat, une investigation a été réalisée sur l'aire d'alimentation d'un captage municipal d'eau potable en territoire agricole au Québec (Pont-Rouge), faisant appel à des mesures de terrain et des simulations numériques. L'étude a porté principalement sur les ions nitrates et les bactéries indicatrices de contamination fécale, principaux indicateurs de pollution de l'eau souterraine en zone agricole. Une série de 38 piézomètres ont été installés sur l'aire d'alimentation dans le but de mesurer des paramètres physico-chimiques et bactériologiques de la qualité de l'eau. Parallèlement à ce suivi de terrain, un modèle déterministe d'écoulement de l'eau souterraine et de transport des nitrates en aquifère granulaire à nappe libre a été élaboré dans le but d'évaluer l'applicabilité du modèle pour la prédiction des teneurs en nitrates au captage municipal. Le calage du modèle comprend une analyse de sensibilité des principaux paramètres et variables du modèle, une étape d'ajustement à des résultats de terrain pour une période déterminée, ainsi qu'une validation du modèle. Suite au calage du modèle, la simulation de divers scénarios a permis de prévoir les effets de changements des pratiques agricoles et de mieux comprendre les teneurs en nitrates mesurées par le passé au captage de la ville. Les résultats d'analyses physico-chimiques démontrent l'impact significatif des activités agricoles sur la qualité de l'eau souterraine, particulièrement les teneurs en nitrates. Les résultats d'analyses microbiologiques montrent pour leur part la forte variabilité des mesures de bactéries indicatrices de contamination fécale au sein de l'aquifère étudié. Enfin, les résultats de modélisation numérique et des scénarios suggèrent que le modèle est adapté pour la simulation des teneurs en nitrates au captage municipal, et qu'une meilleure gestion des pratiques agricoles peut améliorer significativement la qualité de l'eau au captage.

Download or read book The Evolution of National Water Regimes in Europe written by Stefan Kuks and published by Springer Science & Business Media. This book was released on 2004-11-30 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: All over the world countries struggle with water stress. Problems vary from water scarcity and a degrading water quality, to floods and a rising sea level due to climate change. The European Union adopted a Water Framework Directive to improve the sustainability of water management in its member states. Water management should be coordinated at the level of river basins as a whole. Interests of various user groups should be better represented. River basin visions should take into account the impact of all human activities on the status of the resource. Water legislation needs streamlining and more focus on its implementation. The European Union advocates regulating water prices by charging the costs of water services on the basis of full cost recovery and the polluter pays principle. This book examines the development of water management in the Netherlands, Belgium, France, Spain, Italy and Switzerland. It is based on the European research project EUWARENESS. The authors apply a theoretical framework for the analysis of institutional regimes, water governance and property rights. The evolution of national water resource regimes is described over a period of almost 200 years (1800-2000). The long-term perspective enables the reader to see the conditions under which regime transformation and paradigm change are made possible. The book also includes a critical analysis of policy making by the European Union, and a comparative review and analysis of regime development in the six countries involved. This book is followed by another volume published with Kluwer Academic Publishers on "Integrated Governance and Water Basin Management", edited by Hans Bressers and Stefan Kuks.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Using the ecosystem concept as his starting point, the author examines the complex relationship between premodern armed forces and their environment at three levels: landscapes, living beings, and diseases. The study focuses on Europe's Meuse Region, well-known among historians of war as a battleground between France and Germany. By analyzing soldiers' long-term interactions with nature, this book engages with current debates about the ecological impact of the military, and provides new impetus for contemporary armed forces to make greater effort to reduce their environmental footprint.

Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
