Discovering groundwater monitoring networksData come from more than 70,000 representative monitoring stations scattered all over thecountry. These stations measure key components of groundwater quality (qualitometers), andgroundwater levels (piezometers). Some stations can insure both measurements. The ADES databank gives access to descriptive data sheets for all of the monitoring stations: geographicalcoordinates, location on a map, station operators (water agencies, local and regional authorities,decentralized state administrative authorities, the French geological survey –BRGM, etc.),measurement frequencies, aquifers monitored, etc.#Carrying out an effective searchThe ADES data bank proposes several ways to access observation stations, technical data sheets,and data on quality (chemical analyses results) and/or groundwater levels (piezometric head). Itfeatures numbered buttons for quick access. °Quick access, by entering free expression in empty boxes with localization, type of data you arelooking for (monitoring station, parameter, water level); °Advanced search page: you can select by location on a map, or by specific network, company,aquifer, groundwater body or national code (BSS1). Whatever the access route, the results can be stored for later use.# Access, view, data exportThe ADES website provides access to export sets of data and offers users various features suchas: °Maps and photos; °Graphs: plot two chemical parameters for the same qualitometer on the same chart, and up tofive for a piezometric station.°Reliable indicators that are up-to-date, comparable and meet the needs of end-users.The website also offers an indicator on the hydrogeological situation of a piezometer for a longperiod (minimum 10 years), with tables, graphs and maps.
