During the study, the water samples were taken periodically from seven chosen stations in every month. The measured data were given as following (minimum, maximum and average): water temperature (6.7518.21-9.68 0.27 C), pH (6.81-8.11-7.330.03), dissolved oxygen (7.53-13.20-9.360.13 mg/L), conductivity (61.2-82.9-73.83 0.45 µS/cm), nitrite nitrogen (NO2?-N)(0.0009-0.0092-0.0042 0.0002 mg/L), nitrate nitrogen (NO3?-N)(0.81-5.29-1.58 0.09 mg/L) and ammonium nitrogen (NO4-N)(0.0001-0.0097-0.0026 0.0003 mg/L). When the physical and chemical characteristics of Arılı Stream were examined according to the inland water quality standards declared in water pollution law, it is obvious that the river has a high water quality standard (Class I). Thus, it can be said that Arılı Stream water can be used not only for drinking purpose by disinfecting it, but also for recreational aims, aquacultures and other aims.
