Journal Article: The First Deep Quaternary Groundwater Capture In Switzerland- Combined Use And Environmental Benefits

Abstract
Foresighted and determined local authorities, purposeful exploration (i.e. by seismic reflection) and extensive testing led to the discovery of a substantial groundwater resource near the community of Seon (Switzerland) at a depth of 268-305 m. Production tests revealed a hydraulic conductivity of similar to 5.10(-5) m/s, transmissivity of similar to 5.10(-4) m(2)/s and a storage coefficient of similar to 2% in the aquifer. Pumping up to 1500 l/min is sustainable; the water quality complies chemically and bacteriologically with drinking-water requirements. The residence time of several 10(3) years, determined by isotope techniques, guarantees protection from surface contamination. The elevated temperature of 19.5 degrees C of the produced water and space heating. The environmental benefits are substantial: the emission reduction amounts up to 780 tons/year CO2 and 1 ton/year SO2.
