Determination of water quality of Arılı stream (Rize) in terms of physico-chemical structure

In this study, Arılı Stream does not show the effect of seawater on the water from up to 570 m water level, starting about 25 kilometers stream bed set 7 pieces from the station's monthly water samples and appropriate conditions have been based. It has given samples will be taken to the railroad stations during the intake of water from that point on the nature of the examples to be close to residential areas, introduces occurs, determine the total pollution postclassical. During the study will be on the field outside of the physical parameter monthly samples brought to the photometric laboratory analyses have been made. Determinate as Water temperature (6.75- 18.21-9.68 ±0,27 °C), pH (6.81-8.11-7.33±0,03), dissolved oxygen (7.53-13.20-9.36 ±0,13 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). The detected parameters water pollution legislation reported in the continent has been evaluated and the on-water quality standards, water quality has been determined.
