Determination of Physico-Chemical Parameters in the Seman Basin Waters, In the Fieri City

Abstract

- This article presents the results of the study of water pollution of the Seman River basin, based on physico-chemical parameters. This study was conducted during the period April - June 2019. The selection of sampling stations was done in order to the results of the study provide, a complete information on the level of pollution of these waters and the main causes of this pollution. Water samples were analyzed for temperature, pH, conductivity, total suspended solids (TSS), total alkalinity, total hardness, dissolved oxygen (DO), chemical oxygen demand (COD). All analyzes were performed using standard analytical methods (APHA, DIN, ISO). The results were processed using descriptive statistics method and compared with international water quality standards. The results obtained showed that the values of some parameters were above the allowed or recommended norms. Since the main causes of pollution of these waters are discharges of untreated urban water and those from various economic activities, or discharges of wastewaters, it is recommended: Taking measures to minimize the causes of pollution, such as improving the sewerage network of the area, the provision of a completely special system, serious investments in the treatment of untreated urban waters and those from various economic activities as well as the information of the population on the importance of protecting these waters from pollution and the consequences of these pollutions.
