Book excerpt: This is the first book of its kind to focus on the geochemistry of the lanthanide series elements in groundwater/aquifer environments. The contributors are leading researchers in the study of low-temperature geochemistry of rare earth elements. Individual chapters address analytical techniques, water-rock interactions, aqueous complexation, and the reactions and processes that influence these heavy metals along groundwater flow paths.

Book Synopsis Trace Element Geochemistry in Groundwater Flow Systems by : Stephanie Scholten Willis

Download or read book Trace Element Geochemistry in Groundwater Flow Systems written by Stephanie Scholten Willis. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on trace element geochemistry in three groundwater flow systems: the Carrizo Sand, the Upper Floridan, and the Aquia aquifers. The focus is threefold: (i) studying the geochemical behavior, concentrations, and fractionation patterns of rare earth elements (REEs) along two flow paths by examination of both groundwater and sediment samples, (ii) investigating the behavior of arsenic (As) and antimony (Sb) and comparing these data to reveal the biogeochemical processes affecting As and Sb concentrations and speciation as well as determining correlations between As and Sb concentrations, and (iii) formulating adsorption isotherms to demonstrate the adsorption capacity of As onto sediments from the Carrizo Sand and Aquia aquifers. The investigation of the Aquia aquifer groundwaters and sediments indicated the chief source of REEs in the groundwater was due to the dissolution of carbonate minerals (i.e. shell fragments). A statistical relationship was found between As and Sb in the groundwaters of three well defined aquifers (the Carrizo Sand, the Upper Floridan, and the Aquia aquifers), with the best correlation occurring within the Aquia groundwaters. The adsorption isotherms indicate that As(V) strongly adsorbs to the Carrizo Sand aquifer sediments whereas As(III) more preferentially adsorbs to the Aquia aquifer sediments.

Book Synopsis Global Groundwater Resources and Management by : B.S. Paliwal

Download or read book Global Groundwater Resources and Management written by B.S. Paliwal. This book was released on 2017-04-01. Available in PDF, EPUB and Kindle. Book excerpt: The book on “Global Groundwater Resources and Management” has been aimed at growing recognition of depleting world groundwater resources, their contamination, future requirement of the fast growing human population of the world and urgent need of a better groundwater resources management system. The issues are quite complex but now they have crossed all the political boundaries and have become a common cause. The biggest challenge before the scientific community is to integrate valuable scientific advances and technological progress to solve the issue based on holistic and effective sustainable groundwater management. The book comprises the selected papers presented from all over the world at the 33rd International Geological Congress, Oslo, Norway, August 6 -14. 2008. A referee system of high, international standard has been used to review all the papers thoroughly before accepting them for publication. Each paper has been reviewed by at least two internationally recognized subject experts. In many cases as many as 5 or 6 subject experts have been contacted for the review work for a single paper because a much delayed response from the first two reviewers. Fortunately, all of them have sent their review comments simultaneously but at a later date. The book is broadly divided into five sections dealing with key aspects of global groundwater resources and management 1. Groundwater Resources and Management 2. Hydogeological Conditions, Groundwater Assessment and Modeling 3. Hydrogeochemistry and Contamination of Groundwater Resources 4. Exploitation of Groundwater and its Recharge 5. Hazardous Groundwater Conditions In total 31 research papers from Argentina, Australia, Bangladesh, China, Finland, Greece, India, Italy, Mexico, Netherlands, Oman, Poland, Portugal, Russia, Serbia, Turkey and Uzbekistan were selected from the General Symposium: Hydrogeology of the 33rd I.G.C. Oslo-2008. Reviewers were from countries like Argentina, Bangladesh, China, Finland, Greece, India, Indonesia, Italy, Japan, Poland, Portugal, Russia, Serbia, Syria, Thailand, Turkey and Uzbekistan.

Book Synopsis Evolution of Archean Crust and Early Life by : Yildirim Dilek

Download or read book Evolution of Archean Crust and Early Life written by Yildirim Dilek. This book was released on 2013-11-26. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an integrated approach to the study of the evolution of the Archean lithosphere, biosphere and atmosphere, and as such it is a unique contribution to our understanding of the early Earth and life. The structural and geochemical make-up of both the oceanic and continental crust of the Archean Earth is documented in some case studies of various cratons, and the implications of the Phanerozoic plate and plume tectonic processes for the Archean geology are discussed in several chapters in the book. All chapters are process-oriented and data-rich, and reflect the most recent knowledge and information on the Archean Earth. The interdisciplinary approach of examining the evolution of the Archean crust, oceans, and life that we adopt in this book sets it apart from previous publications on Precambrian geology. The book will be attractive to researchers in academia and in industry, and to senior undergraduate students, graduate students and faculty in earth and natural sciences.
