Hydrochemistry of the high-boron groundwaters of the Cornia aquifer (Tuscany, Italy)

The geochemical data, presented in the form of GIS-based geochemical maps, provide a baseline that can be used as a useful diagnostic tool to monitor the hydrochemical evolution of the Cornia groundwaters in view of possible future degradation of their quality in response to natural causes and human activities, including geothermal developments in the general Larderello area.
