- Abstract
The IOR Lake is located in the eastern part of Bucharest, in the Alexandru Ioan Cuza Park of the 3rd district and, based on the available data, is considered a lake of artificial origin, anthropogenic, resulting from the extraction of construction materials from its current perimeter. In relation to the water supply sources, they are included in the category of lakes fed by precipitation (rains, melting snow) but also through some underground springs, having a variable depth. The quality of the lake water is influenced by the organic and inorganic material leached from the slopes that border it, the organic matter accumulated in the sediment, the vegetation that develops on the shores and the presence of economic units (terraces, restaurants, food outlets, etc.). Between October 2020 and April 2021, the colour of the lake water presented a brickish appearance throughout the table, which decreases in intensity in small volumes of water (1-2 litres). The purpose of the obtained analyses and results, as presented in this paper, was to establish a possible cause of this phenomenon. The obtained results showed the presence of mesophilic aerobic heterotrophic bacteria. Of all coliforms in all water samples, colonies characterized by the presence of E. coli bacterium, of fecal steptococci and the absence of total coliforms are highlighted. Colonies of ferrobacteria have been identified and from a chemical point of view the presence of iron oxides in larger quantities is noticeable. Physico-chemical data were within normal values.
