摘要：The hydrographical basin of the Jiu river has a surface of 10.080 km², length of 3876 km and a density of 0,34 km/km². The water resources of the Hydrographical Basin of Jiu are made of surface resources (rivers and natural lakes) and of underground resources. The evaluation process of the anthrop pressures and their impact at the water bodies level leads to the identification of those water bodies that risk not to reach the wanted goals, considering the crossing of the following important stages. To analyze the pressures and the impact, we used the DPSIR concept (Driver-Pressure-State-Impact-Response), being necessary to use information and data regarding the anthrop activities and the changes at the water body status level and the response. Pollution sources of the rivers from the Hydrographical Basin of Jiu are: human crowds, industry and agriculture, hydrotechnical constructions. The level of 2010 the observed quantities of organic substances (expressed as CCO – Cr and CBO5) and of nutrients (total nitrogen and total phosphor) at, on categories of industrial and agricultural pollution sources, from the viewpoint of discharges on p
