Abstract

Water Quality Indices are one of the methods can be used in water quality management as a useful tool in decision making, so this study carried out on evaluating the quality of the Aydughmush river by National Sanitation Foundation Water quality (NSFWQI) and River Pollution Indices (Liou). Materials & Methods: In this cross sectional study standard field parameters including dissolved oxygen, temperature, Biochemical and chemical oxygen Demand, Most Probable Number of Coliforms, Fecal Coliform, Turbidity, Total Dissolved Solids, Total Solids, pH, conductivity and others were measured at eight different stations during one year (2010 to 2011). Sampling points were selected on the basis of their importance. The National Sanitation Foundation Water quality (NSFWQI) and River Pollution Indices (Liou) were used for Aydughmush River water quality assessment. Results: Based on NSFWQI and Liou indices, water quality was found within Moderate category in most of studied stations. Conclusion: Despite difference in used parameters and calculation method in the NSFWQI and Liou indices, the results of both methods overlap for water quality assessment.
