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.

Standing alone as the main authority on the subject, this handbook is the result of a multi-million dollar investigation into groundwater monitoring strategies at energy extraction sites. It gives a detailed, step-by-step description of a proven groundwater monitoring methodology which can be used at all potential pollution sites. This methodology, developed by the author and a ``blue ribbon'' team of hydrologists and hydrogeologists from all over the United States, is endorsed by the U.S. Environmental Protection Agency as ``establishing the state-of-the-art used by industry today''.Although site-specific data are provided, the handbook is developed for general application to coal and oil shale development. All sources of potential groundwater contamination from these two energy extraction types are identified as part of the overall monitoring strategy. Sampling methods are presented, including well design, monitor well placement, sample collection methods, sampling frequency, sample preservation and handling, selection and preservation of constituents for monitoring, sample analysis, and interpretation of water quality data. A complete review is provided of drill stem steps, dual packer tests, long term pump tests, and single packer tests. In addition, hydraulic methods, the application of geophysical techniques including temperature, caliper, gamma ray, spinner, radioactive tracer, velocity, sonic, density, electric, and seisviewer logs are presented. The use of a chronological series of steps, each being fully developed and extensively referenced, means that it is particularly easy to follow for the reader wishing to establish a groundwater monitoring program at a coal or oil shale site. One of the great advantages of the handbook is that it is very detailed, with actual data provided.The handbook is a must for consulting engineers, coal and oil development companies, government and private environmental groups, institutes and universities involved in pollution studies. It will also undoubtedly be used to good advantage by teachers and students for many different types of courses including geological engineering, coal and oil shale mining, environmental geology, sanitary engineering, hydrogeology, etc.

This report (269 pages, 4 plates) presents hydrogeologic, groundwater-monitoring, and hydrochemical studies by the Utah Geological Survey (UGS) in Snake Valley, Tule Valley, and Fish Springs Flat in Millard and Juab Counties, west-central Utah. Data From the newly established UGS groundwater-monitoring network establish current baseline conditions, and will help quantify the effects of future variations in climate and groundwater pumping. New hydrochemical data show that groundwater quality is generally good, major-solute chemistry varies systematically from recharge to discharge areas, and suggest that most groundwater was recharged over one thousand years ago, implying low recharge rates and/or long or slow flow paths. Two aquifer tests yield estimates of transmissivity and storativity for the carbonate-rock and basin-fill aquifers. Variations in the potentiometric surface, hydrogeology, and hydrochemistry are consistent with the hypothesis of regional groundwater flow from Snake Valley northeast to Tule Valley and Fish Springs. Collectively, our work delineates groundwater levels, flow, and chemistry in Snake Valley and adjacent basins to a much greater degree than previously possible, and emphasizes the sensitivity of the groundwater system to possible increases in groundwater pumping.

This volume is the result of work carried out under the NATO SPS Study Pilot Project "Sustainable Use and Protection of Groundwater Resources - Transboundary Water Management." It contains basic information on hydrogeological conditions, groundwater management and monitoring in areas of the Belarus, Lithuanian, Polish and Ukrainian borders, simultaneously borders of the European Union with its eastern partners. In view of the importance of the rational utilization of groundwater reserves, which is essential for our future existence, the book presents recommendations for a united methodology of an integrated groundwater monitoring system in this transnational area. The contributions also cover environmental and surface water issues that have direct effects on groundwater resources. The financial dimension of resource mobilization for environmental projects in Eastern Europe also features as part of a complex project solution.

A complete treatment of the theory and practice of groundwater engineering, The Handbook of Groundwater Engineering, Second Edition provides a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the production of groundwater and the remediation of contaminated groundwater.

"A very well-written handbook." --Ground Water (on the Second Edition) "Presented in a very readable and understandable format." --The Hazardous Waste Consultant (on the Second Edition) The foremost in-depth survey of federal hazardous waste regulations in the United States--now in a new edition The Complete Guide to the Hazardous Waste Regulations is a proven source of clear information on a regulatory system that many find frustratingly complex. Now updated to include additional compliance checklists, Internet resources, and more, this Third Edition provides vital information on all aspects of hazardous materials, from proper on-site management and transportation to appropriate off-site management and cleanup. Author Travis Wagner, one of the nation's leading experts on the subject, provides a step-by-step approach to compliance that goes beyond summarization to help industry professionals truly understand regulations and how they relate to real-world situations. Complete with dozens of user-friendly checklists, flow charts, text boxes, and tables, this indispensable resource includes: * Information on EPA interpretations of regulations not included in other handbooks * Clear explanations of many state-level hazardous waste requirements * A new chapter on spill reporting, giving a step-by-step explanation with attention to multiple federal laws * An appendix listing the Superfund and EPCRA reportable quantity for each RCRA hazardous waste * Additional appendices covering RCRA hazardous wastes, hazardous constituents, groundwater monitoring constituents, permit modification classifications, additional information sources, and important acronyms
