Investigating physical and chemical parameters and detergent levels in Taar River (between Taar Lake and Mamlou Dam)

The aim of this study was to investigate the physical and chemical parameters and determine detergent levels in Taar River (from Taar Lake to Mamlou dam region). In this study, physical and chemical parameters of the river, including pH, DO, EC, COD, BOD, Cl- l levelsand also detergent levels were determined. For this purpose, 5 stations were designated alongside the river. The results showed that the pH levels were between 8.89 -10.12, EC was measured between 380-800 µs/s, DO levels were between 2.14 – 2.8 mg/l, levels of Cl- were between 1.2 - 47 mg/l, BOD measurements showed levels between 0-16 mg/l, COD levels were between 2-36 mg/l and detergent concentrations were less than 0.02 mg/l in all stations. Comparing the results with Department of Environment standards for surface waters, at the time of sampling, the chemical and physical parameters measured and detergent levels of Taar river were in the recommended standard range.
