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. At the geothermal site Blumau in Austria five thermal water samples were taken by Hydroisotop at the production and injection well, as well as after the heat exchanger on 29th of June 2020. Besides the hydrochemical composition, dissolved gases, the heavy metal content, DOC and stable isotopes (18O, 2H, 13C-DIC) were analysed. Additionally, three thermal water samples were taken by the operator on 09th of March 2021 and sent to Hydroisotop for DOC measurements. The dataset contains analysis results associated with the research project reflect. It is a comma separated file (csv) containing the following columns: Location,Country,Description,Laboratory,Lab No.,Sampling date,Temperature at sampling (degC),Spec. electr. conductivity (25 degC) at sampling,Spec. electr. conductivity (25 degC) Lab. (muS/cm),pH value at sampling,pH value Lab.,Temperature Lab. (degC),Dissolved oxygen content (mg/l),Redox potential (mV),Alkalinity (pH 4.3) Lab.
