ΠερίληψηGroundwater is a very important parameter of the hydrological circle, with immediate connection with the surface waters and the atmosphere, while it is a source for the human water needs. Groundwater can transfer dissolved substances to the ground that are important for sustaining the ecosystems, however sometimes it can also transfer dissolved pollutants. The subject of this diploma thesis is the modelling of the groundwater flow and transport of hexavalent chromium in the industrial area of Oinofyta, in the river basin of Asopos. In recent years the pollution of the Asopos River has become the subject of research and publications. In the past there had been studies for the identification of the source of the pollution (human or geogenic). In the wider area it has been found that there is natural pollution because of the ophiolithic formations, however in the study area the levels of hexavalent chromium are far higher than the ones resulting from the weathered rocks. This shows that the source of pollution is manmade. The basic question that the current diploma comes to, answer is the size of the plume of hexavalent chromium as well as the exact place of the source. Hexavalent chromium is one of the forms of chromium which can be found free in nature in low concentrations, whilst in some cases it is a result of specific reactions. It is widely used in the industrial field but it is highly toxic and can become deadly. The modelling of the groundwater flow and the transport of the hexavalent chromium, was performed using PTC (Princeton Transport Code), using the platform of Argus ONE. The simulation was performed for 5 years (2008-2014) and gave conclusions for the groundwater flow as well as the transport of the pollutant. Initially, geology, hydrogeology and rain data are presented, while at the same time the theoretical background of groundwater flow and the hexavalent chromium transport is analyzed. Subsequently there is a description of the tools that were used during the simulation (PTC, Argus ONE, GEO 5). Furthermore, there is an analysis of the parameters and the calibration results in comparison with the field data. Based on the calibration results, conclusions are drawn for the current pollution situation of the area. Finally, according to the results of the calibration, it is obvious that the source of the pollution is because of human activity, placed through the simulation very close to the actual source of pollution. To determine the source of the pollution accurately, systematic and continuous monitoring of the groundwater as well as the surface water and waste disposal, is suggested.en
