Abstract

The Nir River of Nir City is formed by joining of 5 Bolaughlar springs with high debit: two of these springs provide potable water of Nir City. The river flows from the middle of the city and about 35 tons/day of urban, rural and agriculture waste are offloaded to the river. So, the importance of studying of the conditions of chemical and physical pollution is emerged. Factors like physical and chemical parameters, the amount of anions and cations, turbidity, stiffness, dissolved oxygen, biochemical oxygen density, chemical oxygen density, water temperature, pH, CaCO3, fecal and total coliforms were evaluated. Based on the results of this experiment it was concluded that despite the increase of pollutants downstream of the city in comparison to the upstream, studied indices were under the critical limit and were meeting the international standards.
