Groundwater tracing in Burgundy-Franche-Comté: surveillance point – proven return

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 it. About the layer of the restitution points (“tracages_restitutions”): it includes all monitoring points where the return of a tracer product is proven and can be associated with an injection.
