Abstract
Water quality analysis and evaluation processes are very important to understand the quality status and trend of water resources. Moreover, a documented water quality data can serve as an input in identifying the geochemical composition and origin of water resources. The aim of this paper was thus to analyze and evaluate the water quality in Lake Beseka and to suggest appropriate lake water management strategies according to the need. To do so, both the standard laboratory experimentation and graphical methods (software like GW Chart and PHREEQC) were used. Accordingly, the origin of the lake water was found to be deep groundwater with a dominant geochemical composition of sodium bicarbonate. Moreover, the temporal variations and correlations of the water quality parameters were also analyzed. The levels of most of the measured water quality parameters in the lake were found to decrease with time. Finally, the suitability of the lake water for irrigation and drinking purposes was analyzed using the standard methods and compared with the global standards. Lake Beseka was thus classified as unsuitable for both purposes.
