Fingerprinting dissolved organic compounds: A potential tool for identifying the surface infiltration environments of meteoric groundwaters

Supplementary Table S1. Table showing the groundwater major ion and physiochemical parameters from each sampled borehole interval (further dissolved ion chemical data is for the same boreholes from 2014 to 2016 is recorded in Stillings et al. 2020). *Data from Schneeberger et al. (2016) from the same borehole intervals. ΨGroundwater infiltration date and age calculated based on an infiltration altitude of 2200 m and an infiltration temperature based on the year average surface temperature for Grimsel 2°C. Sensitivity analysis reviled altitude variation (1800m – 2600m) and temperature variations (0°C to 10°C) give a variance of 5 years in the predicted groundwater residence time based on piston flow model.
