The main objective of the work package 2 of the REFLECT project is to characterise relevant fluid properties and their reactions for saline fluids (type C). One of the specific goals was to collect fluid samples from several saline fluids from geothermal sites across Europe, determine their properties, and thus contribute to the Fluid Atlas (WP3). Additionally, the REFLECT team will compare those field data with data from lab experiments performed at near natural conditions. Samples of type C fluids were taken from several sites in Germany, Austria, Belgium and the Netherlands. The samples were analysed for major and minor ions, dissolved gases and isotopes. On 29th and 30th of April 2021 five thermal water samples were taken by Hydroisotop from five different springs/wells located at Wildbad-Einöd. The samples were analysed for hydrochemical composition, heavy metals and dissolved organic carbon (DOC) content. It can be noted that the bromide content of sample 361625 is much lower than the bromide content in the other four springs. Since the chloride content in all springs is the same order of magnitude and Cl/Br ratios are expected to be similar in the same The dataset contains analysis results associated with the research project REFLECT.
