Abstract

• Nowadays, water quality issues have become a significant concern due to the growth of population, urban expansion and technological development. The current study is conducted to investigate the water quality status of Dala Township, using the Water Quality Index (WQI) method. The WQI was used to aggregate the diverse parameters into a single term that is helpful for the selection of appropriate treatment technique to meet the drinking water standard. In this study, the WQI of ground and surface water samples were evaluated by analyzing the various parameters such as pH, total hardness, total dissolved solid, conductivity, chloride, nitrate, sulphate, calcium, dissolved oxygen and biological oxygen demand. The WQI values for all the samples were found in the range of 51 - 78. The highest value of WQI was observed in the river water sample and the lowest WQI value was observed in ground water sample. Results of the assessment confirmed that the WQI values of all the water sources are high and they are not suitable for direct consumption.
