Determination of Water Quality Index for Faisalabad City

Water quality index (WQI) is valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate treatment technique to meet the concerned issues. Water quality is considered as a major issue in mega cities of developing countries. The city of Faisalabad has over 5.387 million population. Groundwater is the main source of drinking water in Faisalabad. The groundwater quality should be regularly monitored to cope up with drinking water quality index. However, WQI depicts the composite influence of different water quality parameters and communicates water quality information to the public and legislative decision makers [1]. Despite absence of a globally accepted composite index of water quality, some countries have used and are using aggregated water quality data in the development of water quality indices. Attempts have been made to review the WQI criteria for the appropriateness of drinking water sources. In water quality index (WQI) the study evaluated the groundwater physicochemical parameters (Turbidity, pH, Toral dissolved solids, Nitrates, Total Phosphates, Dissolved Oxygen, Bio-chemical Oxygen Demand, Fecal Coliform, Temperature Changes).
