Hydrochemistry and hydrogen sulfide generating processes

Dec 12, 2013· Knowledge about the hydrochemical conditions of deep groundwater is crucial for the design and operation of geothermal facilities. In this study, the hydrochemical heterogeneity of the groundwaters in the Malm aquifer, Germany, is assessed, and reasons for the extraordinarily high H2S concentrations in the central part of the Bavarian Molasse Basin are proposed.
