Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.

This book was released on 2019-03-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises the selected papers from the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The volume is of interest to all researchers and practitioners in the fields of Hydrology, Hydrogeology, Hydrochemistry, Water Resources and Hydrologic Engineering. Water is a dynamic, finite, and vulnerable but resilient natural resource to be protected in an environmentally sustainable manner. Water systems in different frameworks requires a comprehensive understanding of climatology, geology, hydrogeology, hydrochemistry, hydrodynamics, and surface hydrology. In addition, it is highlighted the role of the variability and climate change in water systems. Furthermore, water has a vital significance to the entire socio-economic sector. This volume offers an overview of the state-of-the-art related to water science and technology in model regions in Europe, Africa, Middle East, Asia and America, but mainly focuses on the Mediterranean environment and surrounding regions. It gives new insights on characterisation, evaluation, quality, management, protection, modelling on environmental hydrology, groundwater, hydrochemistry, sustainable water resources studies and hydrologic engineering approaches by international researchers. Main topics include: 1. Hydrology, Climatology and Water-Related Ecosystems 2. Hydrochemistry and Isotopic Hydrology 3. Groundwater Assessment and Management: mapping, exploration, abstraction and modelling 4. Water Resources Sustainability and Climate Change 5. Hydrologic Engineering and Urban Groundwater

Download or read book Taming the Anarchy written by Tushaar Shah and published by Routledge. This book was released on 2010-09-30 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1947, British India-the part of South Asia that is today's India, Pakistan, and Bangladesh-emerged from the colonial era with the world's largest centrally managed canal irrigation infrastructure. However, as vividly illustrated by Tushaar Shah, the orderly irrigation economy that saved millions of rural poor from droughts and famines is now a vast atomistic system of widely dispersed tube-wells that are drawing groundwater without permits or hindrances. Taming the Anarchy is about the development of this chaos and the prospects to bring it under control. It is about both the massive benefit that the irrigation economy has created and the ill-fare it threatens through depleted aquifers and pollution. Tushaar Shah brings exceptional insight into a socio-ecological phenomenon that has befuddled scientists and policymakers alike. In systematic fashion, he investigates the forces behind the transformation of South Asian irrigation and considers its social, economic, and ecological impacts. He considers what is unique to South Asia and what is in common with other developing regions. He argues that, without effective governance, the resulting groundwater stress threatens the sustenance of the agrarian system and therefore the well being of the nearly one and a half billion people who live in South Asia. Yet, finding solutions is a formidable challenge. The way forward in the short run, Shah suggests, lies in indirect, adaptive strategies that change the conduct of water users. From antiquity until the 1960‘s, agricultural water management in South Asia was predominantly the affair of village communities and/or the state. Today, the region depends on irrigation from some 25 million individually owned groundwater wells. Tushaar Shah provides a fascinating economic, political, and cultural history of the development and use of technology that is also a history of a society in transition. His book provides powerful ideas and lessons for researchers, historians, and policy

Download or read book Protection des eaux souterraines l gislation europ enne et avanc es scientifiques written by QUEVAUVILLER Philippe and published by Lavoisier. This book was released on 2010-09-13 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les eaux souterraines constituent le réservoir le plus important d’eau douce au niveau mondial. Leur rôle pour l’industrie, l’agriculture, ainsi que dans le cycle de l'eau, en particulier pour la maintenance des zones humides et du débit des cours d’eau superficiels (essentiel durant les périodes de sécheresse), est également capital. La préservation et la sauvegarde de cette ressource est donc une nécessité (sur le plan qualitatif et quantitatif) qui concerne à la fois ses usages et sa valeur environnementale. La protection des eaux souterraines a été à l’origine de l’élaboration de nombreux instruments réglementaires européens au cours des trente dernières années. L'ouvrage en expose méthodiquement les justifications, les modes d’emploi et les conditions d’application. À cet effet, le lecteur trouvera : des informations détaillées sur le régime de protection des eaux souterraines mis en place par la législation européenne (directive cadre sur l’eau et sa directive « fille »), ainsi que les descriptions d’avancées scientifiques en soutien à diverses étapes techniques de cette loi européenne, une présentation complète du cadre législatif et scientifique, la description des étapes clés (caractérisation, surveillance, évaluation des risques, programmes d'actions) qui devront permettre d'atteindre le « bon état » des eaux souterraines tel qu'il est exigé par la directive cadre sur l'eau. Ouvrage de référence concernant la législation européenne sur les eaux souterraines, Protection des eaux souterraines s’adresse non seulement aux professionnels de l'eau (gestionnaires, législateurs, industriels) mais également aux chercheurs et au personnel académique. Il est également recommandé aux étudiants en écoles d’ingénieurs.
