Groundwater tracing in Burgundy-Franche-Comté: monitoring point – trace observed

The geographical database includes all groundwater tracings carried out in Burgundy-Franche-Comté since 1829, with the aim of identifying groundwater circulations in the karst zone. It lists more than 2,600 tracing operations carried out by various organisations (research offices, university laboratories, etc.). This data may be used to: * look for a trace on a commune, * visualise groundwater circulations over a geographical area. The data visualised is divided into 8 layers, each of which is detailed in the “learn more” about the layer of points where a trace is observed (“tracages_traces”): it includes all the points monitored following an injection, where the return of a trace product was observed at too low dilution (in trace state) so that its origin can be assuredly attributed to the injection studied. The column ‘output yes/no’ shall be filled in: Trace.
