Chemical analyses from hydrocarbon exploration campaigns showed evidence of the existence of two different groups of brines: halite and halite Ca-Cl brines. Residual brines and leachates are identified by Br-/Cl- ratios. Most of the brines are dissolution brines of Permian evaporites. New analyses show that the pattern of rare-earth elements and yttriurn (REY) are closely linked to H and O isotope distribution. Thermal brines from deep wells and artesian wells indicate isotopically evaporated brines, which chemically interacted with their aquifer environment. Isotopes and rare-earth element patterns prove that cross flow exists, especially in the post-Rupelian aquifer. However, even at depths exceeding 2,000 m, interaquifer flow takes place. The rare-earth element pattern and H and O isotopes identify locally ascending brines. A large-scale lateral groundwater flow has to be assumed because all pre-Rupelian aquifer systems to a depth of at least 500 m are isotopically characterised by Recent or Pleistocene recharge conditions.}, language = {en} } @article{VoigtJennNitsche, author = {Voigt, Hans-J{\"u}rgen and Jenn, Florian and Nitsche, Claus}, title = {European strategies of groundwater monitoring for different aims}, abstract = {Groundwater monitoring systems play an important role in the implementation of the EU WaterFramework Directive.

The distribution pattern of a specific groundwater parameter observed by a number of groundwater monitoring stations within a petrographically comparable groundwater typology is reproduced by two statistical distribution functions, representing the "natural" and "influenced" component. The range of natural groundwater concentrations is characterized by confidence intervals of the distribution function of the natural component. The applicability of the approach was established for 17 hydrochemical different groundwater typologies occurring throughout Germany. Based on groundwater monitoring data from ca. 26,000 groundwater-monitoring stations, 40 different hydrochemical parameters were evaluated for each groundwater typology. For all investigated parameters the range of natural groundwater concentrations has been identified. According to the requirements of the EC Water Framework Directive (article 17) (WFD) this study is a basis for the German position to propose criteria for assessing a reference state for a "good groundwater chemical status".}, language = {en} } @book{LieseNagareJahnkeetal., author = {Liese, Manja and Nagare, Ranjeet and Jahnke, Christoph and Voigt, Hans-J{\"u}rgen}, title = {12 Jahre Pilotbetrieb Karolinenh{\"o}he - zusammenfassende Auswertung}, editor = {Heinzmann, Bernd and Dlubek, Heidi}, publisher = {Berlin : Kompetenzzentrum Wasser Berlin}, isbn = {978-3-9811684-2-6}, language = {de} } @misc{WendlandBertholdFritscheetal., author = {Wendland, Frank and Berthold, Georg and Fritsche, Johann-Gerhard and Herrmann, Frank and Kunkel, Ralf and Voigt, Hans-J{\"u}rgen and Vereecken, Harry}, title = {A conceptual hydrogeological model for evaluating residence times in Hessen}, language = {en} } @incollection{AsohCheoSchmidtetal., author = {Asoh, Eric Ambe and Cheo, Ambe Emmanuel and Schmidt, Michael and Voigt, Hans-J{\"u}rgen}, title = {Comparative Analysis of Environmental and Social Impacts of Cocoa Production: Case Study Cameroon}, series = {Voluntary Standard Systems : a contribution to sustainable development}, booktitle = {Voluntary Standard Systems : a contribution to sustainable development}, editor = {Schmitz-Hoffmann, Carsten and Schmidt, Michael and Hansmann, Berthold and Palekhov, Dmitry}, publisher = {Springer Verlag}, address = {Berlin-Heidelberg}, isbn = {978-3-642-35715-2}, pages = {275 -- 285}, language = {en} } @techreport{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Margi, Fabien and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {CO2-Speicherung in Ostbrandenburg: Implikationen f{\"u}r eine synergetische geothermische Energiegewinnung und Konzeptionierung eines Fr{\"u}hwarnsystems gegen Grundwasserversalzung}, address = {Potsdam [u.a.]}, pages = {125}, language = {de} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Geological Storage of CO2 - Long Term Security Aspects}, editor = {Liebscher, Axel and M{\"u}nch, Ute}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-319-13929-6}, pages = {183 -- 209}, language = {en} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Joint Research Project Brine: Carbon Dioxide Storage in Eastern Brandenburg; Implications for Synergetic Geothermal Heat Recovery and Conceptualization of an Early Warning System Against Freshwater Salinization}, series = {Geological Storage of CO2 - Long Termim Security Aspects}, booktitle = {Geological Storage of CO2 - Long Termim Security Aspects}, editor = {Liebscher, Axel and M{\"u}nch, Ute}, publisher = {Springer}, address = {Cham Switzerland}, isbn = {978-3-319-13929-6}, doi = {10.1007/978-3-319-13930-2}, pages = {183 -- 208}, language = {en} }
