Sažetak
The water quality management is of great importance due to the increasing demand for water in urban areas. This study was conducted to find out the application of GIS tools to determine the quality of water supply in the city of Bhopal. In this study, water quality data at 76 sampling points from different wards were collected from the Nagar Nigam Laboratory, Arera Hills, Bhopal. Different physiochemical parameters are analysed, such as pH, total hardness, Ca hardness, Mg hardness, alkalinity, EC, TDS, chloride, sulphate, and iron. Interpolation techniques were used to analyse the collected data on water quality, and spatial distribution maps were created that show variations in water quality parameters in the city. The inverse distance weighted (IDW) technique of interpolation was used to determine values for the unknown points based on the values of the surrounding data points, and finally, the spatial distribution map was prepared using QGIS Desktop 3.22.16. The weighted arithmetic index (WAI) method was used to calculate the water quality index (WQI), and based on the WQI value, water is categorised into different categories. The spatial distribution map helps to identify the source of pollution, and proper operation and management for the required remedial measures for a specific area.
