Methodology for Hydrogeochemical Sampling to Characterise Groundwaters in Crystalline Bedrock: Developments Made within the Swedish Radwaste Programme

Figure 1

Schematic overview of a general investigation sequence in a telescopic core-drilled borehole designed for chemical characterisation. The most important hydrochemical sampling methods (Complete Chemical Characterisation, i.e., CCC, and monitoring) are shown in boxes with a darker blue colour and text in bold. GW: groundwaters; Eh: redox potential; T: temperature; EC: electrical conductivity. A more detailed description can be found in Supplementary Material 2.
