Çalışma süresince, tespit edilen istasyondan her ay su örnekleri alınmış ve elde edilen değerler (en küçük, en büyük ve ortalama) şu şekilde bulunmuştur: Su sıcaklığı (6.75- 18.21-9.68 i0.27 C), pH (6.81-8.11-7.33i0.03), çözünmüş oksijen (7.53-13.20-9.36d:0.13 mg/L), iletkenlik (61.2-82.9-73.83d:0.45 uS/cm), nitrit azotu (N02_-N)(0.0009-0.0092-0.0042 :t0.0002 mg/L), nitrat azotu (NO3'-N)(0.81--5.29--1.58 :t0.09 mg/L) ve amonyum azotu (NO4-N)(0.0001-0.0097-0.0026This study was carried out purposing to determine water quality of Anh Stream located in Fındıklı, Rize at Eastern Black Sea Region between October, 2013 and September, 2014. During the study, the water samples were taken periodically fi'om seven chosen stations in every month. The measured data were given as following (minimum, maximum and average): water temperature (6.75- 18.21-9.68 i0.27 C), pH (6.81-8.11-7.33i0.03), dissolved oxygen (7.53-13.20-9.36d:0.13 mg/L), conductivity (612-829-7383 0.45 uS/cm), nitrite nitrogen (N02'-N)(0.00090009200042 i0.0002 mg/L), nitrate nitrogen (NO3'-N)(0.81-5.29-1.58 :t0.09 mg/L) and ammonium nitrogen (NO4-N)(0.0001-0.0097-0.0026 :l:0.0003 mg/L). When the physical and chemical characteristics of Anh Stream were examined according to the inland water quality standards declared in water pollution law, it is obvious that the river has high water quality standard (Class I). Thus, it can be said that Anh Stream water can be used not only for drinking purpose by disinfectitrDeniz ve Tatlı Su BiyolojisiArticle3113746262110
