Simultaneous detection of physical and chemical parameters is applied to real-time analysis of groundwater from an Alpine karst spring. Continuous sampling of the spring water was carried out during a half year. Following parameters were recorded by the instrument : groundwater temperature, electrical conductivity and turbidity, dissolved organic matter and concentration of injected artificial dye tracers (uranine, sulforhodamine and Tinopal during 3 tracer tests). This study permitted the
