During the campaign from February 24th until the 1st of March 2017 29 water samples were taken within the Imbrassos basin or related to the studies objectives. Samples of surface and groundwater were taken (Tab. ##REF:watersamples##). These samples are to be analyzed for stable isotopes and water chemistry (major ions, selected trace elements).

A map of sampling locations shows the distribution of samples (figure 1). Sampling locations have been determined with GPS (latitude and longitude). The color of markers indicates the water type: red (surface water), blue (groundwater from borehole), green (groundwater from spring or cistern).
