GHEORGHE ROMANESCU, ELENA PAUN, ION SANDU, IONUT JORA, EMILIAN PANAITESCU, OVIDIU MACHIDON, CRISTIAN STOLERIU QUANTITATIVE AND QUALITATIVE ASSESSMENTS OF GROUNDWATER INTO THE CATCHMENT OF VASLUI RIVER The Vaslui river, a left hand tributary of Barlad, is located in the eastern part of Romania. The monitoring of groundwaters, within water bodies, records information in view of a long term tendency evaluation, both as a result of changes in the natural conditions and as an effect of anthropic activities. The hydrographic network of Vaslui is in deficit, in regard to surface water reserves. The groundwater reserves are richer, but that is of local importance only, as they are often salinized. The main subterranean waters are accumulated in cracks and cavities of the calcareous-sedimentary complex, as well as in the sand of the interfluvial surfaces. The water body GWPRO3, specific to the hydrographic network Vaslui, is a “qualitative risk water body” and its quantity is directly influenced by the quantity of rain. The subterranean waters register a relative flow rate stability, but the reserves are scarce, compared to the rest of the country. The GWPRO5 water body is a cross-basin and cross-border one and it is used in compliance with the European principles for the exploitation of subterranean resources. The qualitatively deteriorated phreatic aquifer consists of alluvial deposits in the waterside and terraces of Vaslui, but also at the bottom of the loess deposits within the interfluvial network. From a hydrological point of view, the Vaslui basin is of low importance. As it is geographically located in the poorest department of the EU, that area is under intense study. Therefore, the hydro-geologic studies represented a priority, in order to emphasize the water reserves. Due to their high flow rate and proper quality, the deep groundwaters are exploited and they can supply the necessary water for certain urban and rural areas.
