This book was released on 1987 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'eau souterraine, une ressource de plus en plus utilisée, est exposée à la pollution par des contaminants organiques. Des mesures pour lutter contre la pollution de cette ressource s'imposent. C'est dans un contexte général de protection de l'environnement et plus particulièrement dans le but de protéger le potentiel des ressources en eau souterraine, que s'inscrit le développement du modèle VULPEST. Ce modèle devrait permettre de prévenir l'aggravation et la prolifération des sites contaminés. Ce modèle d'évaluation de la vulnérabilité devrait s'avérer un outil essentiel pour ceux qui oeuvrent dans les domaines de l'aménagement du territoire, pour ceux qui ont à choisir les lieux d'élimination de nuisances, pour ceux qui ont à délimiter les périmètres de protection, et aussi pour ceux qui doivent surveiller et contrôler la qualité des eaux souterraines.

This book was released on 2002 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Une méthode est proposée pour établir des cartes de zonage de risque de pollution des eaux souterraines. Basée sur une approche de type bassin versant, elle a été appliquée dans la région de Vladimir (Russie), où le territoire a été divisé en zones caractérisées par différents degrés de risque de contamination. L'évaluation du risque prend en compte trois types de facteurs : le niveau de danger de la source de pollution, les paramètres de transfert des polluants et la vulnérabilité des eaux souterraines. Chaque facteur est évalué et intégré dans une couche d'information d'un SIG (Système d'Information Géographique). La méthode d'analyse du risque est fondée sur l'attribution de notes à chacun des facteurs. Une note finale permet de caractériser le niveau de risque de contamination des eaux souterraines. Les résultats de ce zonage montrent que près de 60% du territoire de la région de Vladimir présente un degré élevé ou très élevé de risque de contamination des eaux souterraines

Download or read book Guide technique qualit naturelle des eaux souterraines written by Laurence Chery and published by Editions BRGM. This book was released on 2006 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fond géochimique, valeurs seuils, qualité patrimoniale de l'eau. Derrière ces notions, il y a l'expression d'une nécessité pour tous les professionnels du domaine de l'eau connaître la composition chimique naturelle d'un aquifère. Comment identifier dans la composition chimique actuelle d'une eau souterraine, la part des teneurs naturelles et celle des apports anthropiques (agricoles, industriels, domestiques) ? Comment répondre aux exigences de la Directive Cadre européenne sur l'Eau ? Comment traquer les contaminations anthropiques, établir des stratégies de réhabilitation et anticiper l'évolution de la qualité d'une nappe ? Ce nouveau guide technique s'adresse aux bureaux d'étude, gestionnaires de la ressource, collectivités locales et services de l'Etat. Il propose une méthode d'aide à la caractérisation géochimique des eaux souterraines applicable au contexte géologique français. Le fond géochimique de l'eau résulte principalement de la nature des sols et sous-sols dans lesquels elle a circulé. Une typologie des principaux contextes lithologiques et de la chimie des eaux qui y transitent est présentée sous forme d'une synthèse des connaissances sur les teneurs naturelles en éléments majeurs et en éléments mineurs (éléments indésirables et éléments toxiques) et leurs occurrences sur le territoire. D'autres paramètres et mécanismes influencent le chimisme naturel de l'eau souterraine la température, la pression, la salinité, l'évaporation, le confinement, les drainages acides, les interconnexions d'aquifères et les mélanges associés... Ces processus sont détaillés ainsi que les outils pour les mettre en évidence. Pour discriminer l'influence des différents processus sur la signature géochimique naturelle de l'aquifère, les auteurs ont élaboré une méthode déclinée en trois approches : prédictive : déterminer si le contexte d'un aquifère est porteur de risque d'anomalie " naturelle " ; soustractive : retrouver le fond géochimique d'une eau polluée ; prospective : fournir des recommandations pour mieux calibrer les réseaux de mesure en fonction de leur finalité. Cette nouvelle méthode opérationnelle est illustrée par des exemples pédagogiques dans quatre contextes géologiques représentatifs : socle basaltique (Ardèche), massif carbonaté (Dordogne et Lot-et-Garonne), socle fracturé (Morbihan) et alluvions de la nappe du Rhin. Un cédérom complète cet ouvrage ; il comprend 7 annexes techniques avec, en particulier, des rappels sur l'utilisation des isotopes et des matrices activités-polluants, ainsi que 74 tableaux présentant des états de référence des aquifères français avec une application de recherche multicritère (lithologie, type d'aquifère, teneur en nitrate et distance à la côte).

Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. 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.

Download or read book Nitrates in Groundwater written by Larry W. Canter and published by CRC Press. This book was released on 1996-09-18 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation. It begins by highlighting the nitrogen cycle and related health concerns, providing both background information and a unique perspective on health issues. It then analyzes subsurface processes and the factors and practices that affect them. It thoroughly reviews aquifer vulnerability mapping, an emerging new management tool, and contains a nitrate pollution index that can be used in evaluating actual or potential nitrate pollution from agricultural areas. Best Management Practices are described and evaluated, and possible treatment measures are also explored. Thoroughly researched and well-organized, Nitrates in Groundwater provides a vivid snapshot of the status of nitrates in groundwater today.

Download or read book Sprinkle and Trickle Irrigation written by Jack Keller and published by Springer. This book was released on 2012-11-05 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design text, Sprinkle and Trickle Irrigation, opens up a new and clear window through which to view the physics, economics, design, and manage ment of pressurized irrigation systems. A broad array of system types and ap plications have been covered in detail to provide for complete understanding of systems design. Topics include soil-water-plant relations, general planning con cepts, hydraulics, economics, sizing, operation, maintenance, and special uses. Pressurized irrigation system types covered include hand-line, wheel-line, solid set, traveler, center-pivot, linear-moving and big-gun-sprinkler systems, pump ing systems, and a broad array of trickle system components. The work in this text culminates earlier major works by Jack Keller on the W. R. Ames Company Irrigation Handbook (1967), Rain Bird Sprinkler Man ufacturing Corp. 's Trickle Irrigation Design (1975), and the USDA-Soil Con servation Service's National Engineering Handbook, Section 15: Irrigation Chapter 11: Sprinkle Irrigation (1983) and Chapter 15: Trickle Irrigation (1984). These earlier works form the foundation upon which the majority of currently used design texts are based. The years of design and troubleshooting experiences of the authors and wide ranges of environments and design appli cations in which they have worked have resulted in the substance and robustness of this text in stated relationships and procedures.
