Abstract: Surface and groundwater pollution can be direct and indirect. In the extraction activity, oil and sewage are potential sources of groundwater pollution in the area. Petroleum is extracted from the deposit through methods that constitute both primary and secondary exploatation. The pollution in the areas of petroleum extraction is caused by leaks from the transport pipes. In the majority of the cases, the damages of the transport pipes are caused by the corrosive effect of salt water, which constitute the liquid impurity of the petroleum extract. A large quantity of petroleum products penetrate into the hydrosphere from industrial leaks and refineries, either directly in the sea or via the continental hydrographic network. It is estimated that via all these routes a quantity of 5-10 million tons of oilpenetrate into the ocean waters annually. In the area of Ticleni, surface and groundwater quality indicators were monitored: pH, sulphates, chlorides, conductivity, hardness and oxygen content. The main water course draining under study in the area is the Amaradia River, a tributary of the Jiu River. Here samples were taken for analysis. Comparing the obtained results with the limits stipulated by the Order 161/2006 it is found that the groundwater samples analyzed from the section located at the confluence of Strâmba brook with Cioiana brook corresponds to the third grade in terms of salinity (chlorides), class II for sulphates and class I for the oxygen regime (chemical oxygen demand).
