Indicators of the environmental state of the Bilećko Jezero Lake

Abstract

The research refers to the physical, chemical and microbiological parameters of the Bilećko Jezero Lake water quality. The monitoring of physical and chemical parameters and their interaction with other parameters helps estimate the water quality and any possible changes. Some parameter values and their alteration directly affect the water life. The research was performed at three sites: the Grančarevo watergate, the Trebisnjica River fountain and Orah in the period 2006-2009, and the results of conducted physical and chemical analyses indicate that the water quality was satisfactory, albeit with certain deviations. Bacteriological analyses showed that the water of Bileća accumulation, especially at the Izvor site, was burdened with fecal material.
