This paper tries to present the concentration dynamic of the principal quality indicators of the groundwater from Balesti-Tamasesti perimeter, Gorj County, in the last 45 years, in a special geographical area - with groundwater very closed to the land surface, making them very vulnerable to anthropic pollution, the area being declared under common Order of MESD and MARD no 1.552/03.12.2008/743/12.12.2008 as an area included on the list of localities with nitrates sources from agricultural activities. The characterization of the groundwater quality from the studied perimeter was based on the physico-chemical analysis bulletins of hydro geological drillings from the national network of groundwater monitoring, from their execution (period 1970-1974), from these in the studied perimeter being part the hydro geological stations, as well as the citizens wells (2013-2015); the monitored wells have been chosen on the flow direction of groundwaters established by original hydro geologic map and hydro geologic section, elaborated through Sub Carpathian hillock depression. According to the report on the implementation of the Nitrates Directive published by the European Commission, Southern Romania is among the areas in the EU where groundwater contain elevated levels of nitrates, due to use of chemical fertilizers and organic nitrates, as a major source of water pollution. In all 27 Member States is a decrease in the quantities of nitrate in water, so that the implementation of legislation designed to prevent pollution of land and water with nitrates from agriculture became a success. Following the conducted monitoring in Gorj area - Romania, we observed a significant appreciation of quality indicators of groundwater, sowe could recommend implementation of measures to protect and continuing rehabilitating groundwater quality in Baleşti by building some sewage-evacuation-disposal plants, because the quality of groundwater here could return to further nitrogen compound concentration values existing in the natural background of groundwater.
