Results of a study about tracing tests transfer functions variability in karst environment
Abstract:
Artificial tracing tests are often used to simulate migration of a point-source contaminant under various hydrological conditions in karst hydrogeological impact assessment or to define groundwater protection zones. Due to economic reasons, it is rather difficult to carry out adequate tracing tests to determine what are the possible recovery curves over range of discharges at the outlet, are the tracer test results representative of the spring watercatchment being protected ? Our objective was to characterize the tracing-systems in a karst environment by a mean transfer function; such transfer function may be used to predict the breakthrough curve of a point-source contaminant taking into account an error factor. A Jura mean transfer function with + and -95% interval confidence functions can be established and differentiated from the Alps mean transfer function. The use of this transfer function to predict the response of a point-source contaminant requires considerations of water catchment size, thickness or the aquifer and discharge at the outlet. The results of this variability analysis confirm that the transfer functions by themselves may not be used to protect the whole karst spring water catchment, as this one is affected by the heterogeneity of the physical parameters. At the scale of a water catchment, transfer functions are not the major tool to protect the groundwater. But with a multiattribute approach of vulnerability mapping, transfer functions contribute to the development of groundwater protection strategy.
