A geochemical study concerning surface waters and groundwaters from the Mediterranean Var River catchment (south-east France) is undertaken to better understand this hydrological system and to establish a hydro-geochemical natural background. Preliminary data show that geology of the catchment is sufficiently contrasted to give specific geochemical signatures to the different components of the catchment. Concentration ratios of selected trace elements allow defining (1) distinct natural domains for river groups inside the catchment, and (2) anthropogenic contributions. The Tinée tributary is affected by natural arsenic pollution, probably mainly originating from metamorphic rocks of the Mercantour massif.
