Groundwater tracing in Burgundy-Franche-Comté: injection point – injection carried out

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 injections (“tracages_injections”): this file includes all the points of the injections carried out, including when no restitution has been found. Attention: an injection site is likely to be present several times, for several reasons: - the fact that several injections were carried out on different dates, - as many as there are points that are monitored following an injection on a given date.
