Book Description
Pour étudier la vulnérabilité des captages prélevant les eaux des nappes du Miocène et de l'Oligocène vulnérable, la première étape a consisté à créer une base de données géo-référencée. Pour ce faire, la délimitation des aires d'alimentation des captages (AAC), l'inventaire des activités porteuses de risques au sein de ces AAC, ainsi que l'identification des produits et substances chimiques associées à ces activités ont été effectués. L'exploitation de cette base de données a permis de réaliser des cartographies de vulnérabilité et de risque de pollution industrielle pour chaque aire d'alimentation. A l'aide de ces cartes de risques, et en confrontant les secteurs les plus vulnérables des AAC à la carte d'occupation du sol, les captages les plus vulnérables ont pu être identifiés. Des mesures de gestion de risque pour ces captages ont par la suite pu être proposées. L'inventaire des méthodes de traitement biologique des perchlorates mené en parallèle à l'étude de vulnérabilité à révélé que l'atténuation naturelle contrôlée (ANC), la bioremédiation in situ (BIS), la bioremédiation ex-situ, la phytoremédiation et les zones humides artificielles sont les méthodes de traitement biologique des perchlorates dans les eaux souterraines. Pour une éventuelle application de l'ANC et de la BIS au sein de la nappe de l'Oligocène exploitée, et de la nappe alluviale de la Garonne faisant l'objet d'un projet d'exploitation, des tests de laboratoire ou de terrain sont nécessaires afin de juger de la présence ou non des conditions favorables à ces méthodes dans les milieux.

Book Description
Rural–Urban Water Struggles compiles diverse analyses of rural–urban water connections, discourses, identities and struggles evolving in the context of urbanization around the world. Departing from an understanding of urbanization as a process of constant making and remaking of multi-scalar territorial interactions that extend beyond traditional city boundaries and that deeply reconfigure rural–urban hydrosocial territories and interlinkages, the chapters demonstrate the need to reconsider and trouble the rural–urban dichotomy. The contributors scrutinize how existing approaches for securing urban water supply – ranging from water transfers to payments for ecosystem services – all rely on a myriad of techniques: they are produced by, and embedded in, specific institutional and legal arrangements, actor alliances, discourses, interests and technologies entwining local, regional and global scales. The different chapters show the need to better understand on-the-ground realities, taking account of inequalities in water access and control, as well as representation and cultural-political recognition among rural and urban subjects. Rural–Urban Water Struggles will be of great use to scholars of water governance and justice, environmental justice and political ecology. This book was originally published as a special issue of Water International.

Book Description
Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book Description
Globalized Water presents a compilation of voices that forms a unique scientific exploration of contemporary water management models and governance issues. The book describes the water paradox—how a local resource has become a global product—and the implications of this in how we identify challenges and make policy in the water sector. Over the last 20 years, the foundations of local and national water systems have been rocked by a wave of changes. The authors in this book, experts in a wide range of disciplines, address the resulting debates and issues: water as a commodity and patrimony, technological rent, liberalization and privatization, the continuing evolution of water management and policy at the European level, decision making and stakeholder participation, conflict and consensus, and the inevitable growth of counterpowers at the local and international levels, promoted by the advocates of sustainable development. The selected case studies are from Europe (primarily France but also Spain, Germany, the United Kingdom, and Portugal), Latin America (Argentina, Bolivia), the United States, Lebanon, and India. From this diverse collection of comparative perspectives and research methods, Globalized Water seeks to advance interdisciplinary research, contributing to a new and dynamic role for social sciences and governance on water.

Book Description
Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

Book Description
This text combines the science and engineering of hydrogeology in an accessible, innovative style. As well as providing physical descriptions and characterisations of hydrogeological processes, it also sets out the corresponding mathematical equations for groundwater flow and solute/heat transport calculations. And, within this, the methodological and conceptual aspects for flow and contaminant transport modelling are discussed in detail. This comprehensive analysis forms the ideal textbook for graduate and undergraduate students interested in groundwater resources and engineering, and indeed its analyses can apply to researchers and professionals involved in the area.
