Title: | Control of inorganic and organic contamination, assessment of water quality in hydropower lakes on Jiu River | Authors: | Radulescu, Victorita | Keywords: | Environmental engineering;Hydroelectric power generation pollution;Water | Issue Date: | 2017 | Publisher: | National Research and Development Institute for Industrial Ecology, INCD-ECOIND | Abstract: | In the last decades near the hydropower lakes, have developed numerous private companies and settlements that constantly uses water from these lakes. In many cases, the spills are not controlled and are not decontaminated properly or even at all. In the Jiu hydrographic basin, there are 225 localities with a population of more than 2,000 peoples. Only 32 of them are equipped with sewer systems and only 2 of them in accordance with Directive 91/271/EEC. As consequence of the pollution with organic and inorganic substances (nutrients) has appeared the eutrophication of the lakes. From the total 12-hydropower lakes with a surface over 50 ha, eight of them are clogged in the proportion of 60%, and 3 of them in a proportion of 80%. In the first part of the paper are analyzed the main punctual and diffuse sources of organic and inorganic pollution, with a decisive factor in the development of the aquatic vegetation. During 2010-2016, a systematic campaign of measurements was done. They were determined the protection zones that need to be tracked, the catchments zone for the human consumption, the zones for protected fish or of those species economically important, the natural protected areas, and the zones vulnerable to nitrate and nitrites. The obtained results are presented for the most affected hydropower lakes from the selected area. Finally, are mentioned some possibilities and measures necessary to be followed as to reduce the inorganic and organic pollution, some conclusions, acknowledgement and references. |
