Groundwater is sometimes called “the hidden asset” – awareness of its existence and its importance is not well known and as a consequence the measures which are required to protect and manage it in an environmental sustainable way are either not taken or are taken too late. Where pollution has occurred and measures are taken too late it may take decades, or longer, until the necessary restoration of quality is achieved. This comprehensive text presents in the following sections: Groundwater monitoring in the regulatory and international context Conceptual modelling and network design Groundwater pollutants and other pressures Groundwater quality standards and trend assessment Case studies for groundwater assessment and monitoring in the light of EU legislation Groundwater measurements Associating external stakeholders The editors have collected state-of-the-art information on groundwater quality assessment monitoring from the international community, providing further stimulation to the work of all parties involved in the challenges this area creates to ensure sound quality assessment of groundwater.
Ground water serves as the main source of drinking water for 50% of the United States as a whole—and for 97% of rural populations, in particular. In addition to public concern with point sources of contamination, such as landfills and hazardous waste disposal sites, current attention has now come to focus on the overall quality of ground-water resources. Regional Ground-Water Quality offers the first detailed guidance for conducting ground-water quality investigations in a regional context. This exceptional volume combines hydrogeologic and geochemical principles, as well as statistical principles, within a unique conceptual framework that helps readers produce efficient, meaningful, and successful ground-water assessments. Regional Ground-Water Quality will be a valuable resource when first approaching a regional-scale study and when designing specific regional-scale studies. Throughout the book, topics emphasize the value of studying regional ground-water quality at multiple spatial and temporal scales. Up-to-date coverage of essential processes and methodologies includes: multi-scale design concepts for regional ground-water quality studies the fate and transport of organic and inorganic materials, including nitrates, pesticides, pathogens, acid precipitation, natural radionuclides, saltwater intrusion, and problems in karst aquifers basic concepts of organic and inorganic chemistry a review of environmental isotopes and geochemical modeling statistical concepts for ground-water quality surveys and geostatistical analysis the effects of surface-water/ground-water interactions on ground-water quality the relationship between ground-water quality and land use regional geochemistry principles Readers will be brought completely up to date with the latest research in ground-water assessments, such as novel methods for dating young ground water, including the use of CFCs, tritium/helium-3, and krypton-85. The book also examines the uses of organic compounds as time and source markers, ground-water vulnerability analyses, applications of subsurface microbiology at the regional scale, and design of well-water surveys. Invaluable case studies drawn from international projects graphically demonstrate concepts discussed in the book. These case studies describe successful regional ground-water assessment efforts conducted in various areas and include a look at the uses and limitations of existing ground-water quality data. A first-of-its-kind resource, Regional Ground-Water Quality will be essential reading for scientists and engineers in hydrology, water resources, agricultural sciences, and environmental sciences. It will also be of interest to engineers and R&D personnel in government, industry, and private consulting, as well as to professionals involved with the design and interpretation of studies.

The concluding study aims to assess the extent of exposure to fluoride in inhabitants of Raebareli district in Uttar Pradesh, India, generating baseline data about the fluoride-contaminated area"--
Geoenvironmental engineering issues are of increasing importance around the world. This international trend is apparent in the UK governments active encouragement of the use of brownfield sites for urban development to ease the pressure on the countryside. This book contains the collected papers from the 2nd Geoenvironmental Engineering Conference, organised by the British Geotechnical Society and Cardiff Universitys Geoenvironmental Engineering Research Centre.
This book comprehensively discusses the methods and practices for evaluating geochemical processes in aquifer groundwater. Possible occurrence and mechanisms of rock-water interaction, trace metal mobilization, thermodynamic explanation, actions of aquifer CO2, pollution sources, geogenic influencing factors, and isotope dilution methods are the primary areas of focus. These water quality variables are analyzed using a variety of logical/theoretical explanations, statistical techniques, and experimental procedures to determine the suitability of groundwater for drinking, irrigation, and other industrial purposes. The work is an important addition to hydrogeochemical literature since many existing indexing methods for the assessment of water quality are very old and have some degree of limitation. The book will be a useful resource for students, lecturers, and researchers working in the fields of hydrogeochemistry, hydrology, water pollution, and groundwater quality.
