Carismeau: isotopic and geochemical characterisation of water masses in the Adour Garonne basin: interconnections and heterogeneities - Phase 1 report. Isotopic and geochemical characterisation of water masses in the Adour Garonne basin: interconnections and heterogeneities - Carismeau Final report, Volume 1: Isotopic tools applied to water resource management. Example of the water mass of Infra-Molasse sands. Final report, Volume 2: Coupled hydrogeological and geochemical approach to Infra-Molasse sands of the Adour-Garonne basin

A first report proposes an overview of hydrogeological and chemical knowledge of the Aquitaine basin (geological history, Eocene aquifers, Infra-Molasse sand aquifers, Paleocene aquifers), a determination of physical-chemical well-logging of underground waters (methods, application, and interpretation), a study of underground water chemistry (protocol, analysis, results and interpretation of sampling campaign in May 2006), a report of an isotopic approach to underground waters during this campaign of May 2006 and the presentation of another sampling campaign performed in October 2006. The last chapter presents communication actions (web site, scientific valorization). The second report presents the objectives and means of the Carismeau project, recalls various aspects concerning the definition, measurements and operation of isotopes, presents isotopic tools, and report their application to the management of water resources. Synthesis sheets are proposed, as well as abstracts of contributions to conferences and submitted articles.
