Book Description
The safe disposal of radioactive wastes by burial in deep geological formations requires long-term predictions of the future behaviour of the wastes and their engineered repository. Such predictions can be tested by evaluating processes analogous to those which will occur in a repository, which have been long active in the natural geochemical environment. The Pocos de Caldas Project is a comprehensive study of two ore deposits in Minas Gerais, Brazil, aimed at looking at uranium and thorium series radionuclide and rare-earth element mobility, the development and movement of redox fronts, and the nature of natural groundwater colloids. A multidisciplinary team of experts from 27 laboratories carried out a fully integrated study of the geology, geomorphology, hydrogeology, geochemistry, hydrochemistry and geomicrobiology of the two sites for nearly four years. This book contains 20 papers covering the detailed findings, with particular emphasis on their significance for radioactive waste disposal, especially on the use of the data in testing models of radionuclide movement. It will interest economic geologists, geochemists and performance assessment modellers involved in the geological disposal of radioactive wastes.

Book Description
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 Description
This volume provides a comprehensive overview on the chemical thermodynamics of those elements that are of particular importance in the safety assessment of radioactive waste disposal systems. This is the first volume in a series of critical reviews to be published on this subject. The book provides an extensive compilation of chemical thermodynamic data for uranium. A description of procedures for activity corrections and uncertainty estimates is given. A critical discussion of data needed for nuclear waste management assessments, including areas where significant gaps of knowledge exist is presented. A detailed inventory of chemical thermodynamic data for inorganic compounds and complexes of uranium is listed. Data and their uncertainty limits are recommended for 74 aqueous complexes and 199 solid and 31 gaseous compounds containing uranium, and on 52 aqueous and 17 solid auxiliary species containing no uranium. The data are internally consistent and compatible with the CODATA Key Values. The book contains a detailed discussion of procedures used for activity factor corrections in aqueous solution, as well as including methods for making uncertainty estimates.

Book Description
In natural waters, trace elements-especially metals-may be present in different physicochemical forms varying in size, charge, and density. Trace Elements in Natural Waters comprehensively covers the microchemical processes occurring in the water phase. The book describes geological and biological interactions involving supply or removal of trace elements in the water phase. Analytical aspects are included, since sampling, pre-analysis handling, and methods of analysis strongly influence the quality of data. Different natural water systems are reviewed with respect to sources, concentration levels, and physicochemical forms of trace elements. Also, important fields of future research are investigated.

Book Description
Aquatic Chemistry An Introduction Emphasizing Chemical Equilibria in Natural Waters Second Edition Edited by Werner Stumm and James J. Morgan This second edition of the renowned classic unites concepts, applications, and techniques with the growing amounts of data in the field. Expanded treatment is offered on steady-state and dynamic models employing mass-balance approaches and kinetic information. New chapters address such topics as: environmental aspects of aquatic chemistry; new material on organic compounds in natural water systems; the use of stable and radioactive isotopes in chemical and physical processes; the latest advances in marine chemistry; solid-solution interface; kinetic considerations of equilibria; metal-ligand interactions; and an expanded compilation of thermodynamic data for important reactions in natural water systems. 1981 (0 471-04831-3) Cloth 780 pp. (0 471-09173-1) Paper Chemical Processes in Lakes Edited by Werner Stumm This is a multidisciplinary analysis of recent research on the physical, chemical, and biological processes in aquatic systems. Coverage includes: distribution of elements and compounds in water and sediments; sedimentation and sediment accumulation of nutrients and pollutants; eurtophication and acidification; atmospheric deposition; redox-related geochemistry and sediment-water exchange of nutrients and metals; sediment dating and paleolimnology; and steady-state and dynamic models. Most chapters focus on the role of biological processes and the coupling of elemental cycles by organisms. 1985 (0 471-88261-5) 435 pp. Principles of Aquatic Chemistry Francois M. M. Morel Here is a quantitative treatment of the chemical principles that govern the composition of natural waters. Features include an in-depth examination of the use of conservation principles in chemical systems, a review of thermodynamic and kinetic principles applicable to aquatic systems, and a novel presentation of a systematic methodology for equilibrium calculations. Detailed coverage is provided on the topic of aquatic chemistry, following the traditional divisions of acid-base, precipitation-dissolution, coordination, redox and surface reactions. 1983 (0 471-08683-5) 446 pp.
