Data on geothermal properties are notoriously scarce, both on a good temporal and spatial resolution. We compared two data sets of a geothermal well in Bavaria (one had yearly analyses of a great number of ions, the other one tested the water every five minutes but only on a small number of variables) and found that yearly data systematically neglect seasonal variations taking place in the aquifer. Virtual sensors might help to combine the two data sets when the aquifer is well known.

Stormwater could augment our over-drafted urban groundwater resources. Therefore, it is of the utmost importance to fully understand stormwater contaminant presence, transport, and fate in the built environment to design novel or improve conventional treatment systems. Preliminary results have confirmed presence of toxic metals in Barcelona urban runoff (with significant differences depending on the catchment areas), along with decreased metal concentrations at green infrastructure outlets.

The overall objective of the CHENILLE project is to performed an in-situ experiment in the Underground Reaserch Laboratory of Tournemire (Southern France) consisting of hydraulic and thermal stimulation of a fault zone. This experiment is monitored with extensive geophysical means (passive seismic, active seismic, distributed fiber optics for temperature measurements) in order to unravel the physical processes taking place during the stimulation for a better charactization of fault zones.
