Abstract
In recent years, the use of water quality indices (WQI) to ensure the safety of drinking water has expanded. The WQI is used to simplify and facilitate rapid, accurate interpretation of drinking water test results. In this study, the quality of drinking water in Shahrekord was investigated. This study involves measuring eight physicochemical parameters (pH, EC, TDS, TH, SO4-2, PO43-, NO3-, Turbidity) of drinking water taken from the urban water network and calculating the water quality index. The obtained water quality index obtained for all water samples was below 5050, indicating excellent and very good quality of Shahrekord's drinking water. After applying principal component analysis, the results indicated that first component, with the highest eigenvalue, is influenced by parameters such as sulfate, nitrate, electrical conductivity (EC), and total dissolved solids (TDS), confirming the salinity and chemical water quality are dominant. The second component, driven by phosphate, total hardness (TH), and turbidity, reflects the physical properties and hardness of water. The third component is associated with the contribution of phosphate and hardness. EC and TDS exhibit a high correlation.
