Book Description
The hypothesis suggests that there may be vertical fractures and solution channels throughout the Floridan Aquifer System (FAS) that cause ground water from the upper and lower Floridan aquifers to interact with one another. The FAS is separated into three different hydrostratigraphic units, the upper Floridan aquifer, middle-confining unit, and the lower Floridan aquifer. This paper summarizes the hydrogeologic framework of the FAS underlying southwest Florida. Stable isotopes (2H, 18O) and uncorrected Radiocarbon (14C) data were used to define two different water types within the FAS and the possible interaction between the two aquifers. The South Florida Water Management District (SFWMD) collected 42 samples from the Floridan aquifer at 16 sites. Plots of 2H and 18O were used to define the two different groundwaters that make up the FAS and to discover if there is any evidence of interaction between the two aquifers. Uncorrected 14C data were used to verify the different groundwaters within the FAS by dating them and to show a generalized direction of flow in each hydrostratigraphic unit.

Book Description
Environmental isotope and nuclear techniques provide unmatched insights into the processes governing the water cycle and its variability. This monograph presents state of the art applications and new developments of isotopes in hydrology, environmental disciplines and climate change studies. Coverage ranges from the assessment of groundwater resources in terms of recharge and flow regime to studies of the past and present global environmental and climate changes.

Book Description
This guidebook provides theoretical and practical information for using a variety of isotope tracers for dating old groundwater, i.e. water stored in geological formations for periods ranging from about 1000 to one million years. Theoretical underpinnings of the methods and guidelines for their use in different hydrogeological environments are described. The guidebook also presents a number of case studies providing insight into how various isotopes have been used in aquifers around the world. The methods, findings and conclusions presented in this publication will enable students and practicing groundwater scientists to evaluate the use of isotope dating tools for specific issues related to the assessment and management of groundwater resources. In addition, the guidebook will be of use to the scientific community interested in issues related to radioactive waste disposal in geological repositories.

Book Description
Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.

Book Description
The twelve chapters of this volume aim to provide a complete manual for using noble gases in terrestrial geochemistry, covering applications which range from high temperature processes deep in the Earth’s interior to tracing climatic variations using noble gases trapped in ice cores, groundwaters and modern sediments. Other chapters cover noble gases in crustal (aqueous, CO2 and hydrocarbon) fluids and laboratory techniques for determining noble gas solubilities and diffusivities under geologically relevant conditions. Each chapter deals with the fundamentals of the analysis and interpretation of the data, detailing sampling and sampling strategies, techniques for analysis, sources of error and their estimation, including data treatment and data interpretation using recent case studies.

Book Description
This book focuses on Romania’s more than 12,000 caves, which developed in limestone (including thermal water caves), salt, gypsum, and occasionally in sandstone. It examines these caves and related topics in a format suitable for cavers, while also addressing a broad range of aspects useful for students and researchers. Since the Institute of Speleology was first established by Emil Racovita in 1920, a great deal of research has been conducted on all cave and karst types. As such, the book examines a variety of scientific fields, including karst geology, hydrogeology, biospeleology, paleoclimatology, mineralogy and archaeology.

Book Description
Geochemical Techniques for Identifying Sources of Ground-Water Salinization offers a comprehensive look at the threat to the United States' freshwater resources due to salinization and outlines techniques that can be used to study the problem. The book reviews the seven major salt-water sources that commonly mix and deteriorate our fresh ground water (natural saline ground water, halite solution, sea-water intrusion, oil- and gas-field brines, agriculture effluents, saline seep, and road salting). Other topics covered are the characteristics of saltwater sources, geochemical parameters, and basic graphical and statistical methods that are frequently used in saltwater studies. The book also provides geographical charts showing the distribution of the major salt-water sources, illustrating which ones are potential sources in any given area in the United States.Geochemical Techniques for Identifying Sources of Ground-Water Salinization describes the individual geochemical parameters used in identifying salinization and the information on how and where to obtain them. This is an informative book for anyone interested in the present and future quality of our fresh-water supply.

Book Description
This monograph represents many years of groundwater data accumulation by a large number of noted hydrogeologists located throughout the world. It represents a multicultural approach to groundwater resources and their use. As a result, many of the fundamental concepts in hydrogeology are interpreted slightly differently in other countries. In fact, there are a number of hydrogeologic phenomena introduced that for the most part have not been presented internationally. Since various cultures review the science of hydrogeology with their own nuances, a substantial effort was made to provide classic references in the science of hydrogeology. The focus of the monograph was to present data and scientific principals, which are relevant to groundwater use in each of the countries. This monograph represents a major undertaking by hydrologists and hydrogeologists around the world. Although the fundamental groundwater resource data may change slowly over time, the groundwater use data is rapidly changing. Consulting hydrogeologists, engineers, chemists, geologists, biologists, health officials, and government environmental administrators will find this baseline document of substantial value. It is fully anticipated that this book will serve as the first addition of a series on groundwater resources of the world and their use.
