چکیده مقاله:
Surface water quality management is very important. Qualitative indicators of water pollution can indicate the trend of quality changes over time and place. The aim of this study was to evaluate the quality of Golin river using IRWQISC index. For this purpose, the Golin river water was sampled twice a month in a period of one year from May ۲۰۱۹ to April ۲۰۲۰ in Najar village station located in downstream of river. Different parameters which evaluated in this study were DO, pH, BOD۵, COD, nitrate, phosphate, electrical conductivity, total hardness and turbidity. The results of the study using the IRWQISC index showed that the range of the index values in the warm months of the year was "between" ۳۰.۵۷ to ۳۲.۱۷ with relatively poor-quality category. While in the cold months of the year the index values obtained "between" ۲۷.۳۶ to ۲۷.۸۳ with poor quality category. In general, according to the results from the annual average of the IRWQISC index, the numerical value was obtained as equal to ۲۹.۶۲, which showed Golin river in poor quality category.
