Map Viewing Service (WMS) of the dataset: Piezometric Stations in Provence-Alpes-Côte-d’Azur

Strictly speaking, a piezometric station or pezometer is an apparatus set up to monitor changes in the level of an aquifer or a groundwater table. The data collected over a large number of years provides a good understanding of the aquifer at the measuring station. However, for practical reasons, the SANDRE group has extended this concept to that of a piezometric observation point, which is either a man-built structure (wells, drilling, gravel, etc.), or a natural point (source, aven, cave,...) which makes it possible to measure the level of a tablecloth. Theoretically, a pezometer only measures the level of one and one layer. In fact, a pezometer can reach several layers whose piezometric levels may be different. The Pizometer Network is the monitoring network under the Groundwater Framework Directive DREAL PACA no longer manages this data, subcontracting has been entrusted to the BRGM. The data produced by the BRGM network are made available to the public, administrations or design offices on the internet server of the Rhône-Méditerranée-Corse basin where information is presented in the ADES bank.
