Book Description
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 pr

Book Description
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.

Book Description
Cet ouvrage présente un état des connaissances actuelles indispensables pour comprendre leurs mécanismes des pollutions et les milieux étudiés. Il rassemble les bases théoriques permettant d’appréhender le comportement de polluants tant d’origine agricole (nitrates et pesticides) qu’organique (virus et bactéries) ou industrielle. Il présente diverses méthodes pour les identifier, évaluer leur concentration, leur origine ou leur devenir. Les processus géochimiques à l’œuvre dans chaque milieu naturel (sols et aquifères) sont décrits, ainsi que l’influence de la morphologie des sédiments et des écoulements sur ces processus. Enfin, ce livre détaille les outils nécessaires aux professionnels : bases de la législation, modes de prélèvement, techniques de réhabilitation, réactions chimiques advenant dans le milieu rural. Le dernier chapitre est consacré aux logiciels de modélisation des réactions chimiques dans le contexte des pollutions, outils modernes en fort développement. L’actualisation de cette nouvelle version porte sur la législation, avec une mise à jour des données issues du Code de l’environnement, et sur la procédure réglementaire de traitement des sites et sols pollués qui a évolué de façon significative en France depuis 2007. Chimie et pollutions des eaux souterraines est un guide pratique : ● il offre une sélection de faits majeurs favorisant l’acquisition des notions les plus complexes et leur application sur le terrain ; ● les nombreuses illustrations présentent des exemples réels ou des vues synthétiques des processus en jeu ; ● chaque chapitre, consacré à un milieu défini ou à une pollution type, peut être abordé de façon autonome pour répondre à une question précise.

Book Description
The first book devoted entirely to the problem of nitrate risk and behaviour in groundwater, this volume includes twenty-seven papers selected from those presented during the Euromeeting of the International Association of Hydrogeologists "Nitrate in Groundwater in Europe" held in Wisla, Poland in 2002. The problems presented and discussed in Wisla covered all aspects of nitrate pollution of groundwaters globally, while the articles describing the case studies focus on groundwater in Europe. The remaining chapters examine the main chemical and physical processes which affect nitrate in groundwater, as well as describing nitrate distribution in various aquifers, seen as an essential problem areas of groundwater protection.
