As practical as it is historical
The Toulon springs system in Périgueux is the outlet of a drainage basin whose size is on the order of 80 km2. It is a major concern for the city of Périgueux because it is the city’s only water resource. The operator Suez Environnement has monitored flows at this site since 2005. In 2016 within the framework of a I2M dissertation, equipment was upgraded to continuous monitoring of multiple physico-chemical and hydrochemical parameters (Conductivity, T°C, Turbidity, pH, O2, COT, COD, NO3). These observations are geared toward:
- studying the vulnerability of the karst resource to inputs including: nitrates, organic carbon, turbidity, and bacteriology,
- understanding the functioning of the multi-layer karst system in which polyphase karstification has occurred,
- modeling transfers of pressure and mass in a multilayer karst system.
