AN EXTENSIVE WATER QUALITY ASSESSMENT OF POTABLE WATER COLLECTED FROM DOMESTIC AND COMMERCIAL LOCATIONS: A CASE STUDY OF LARKANA CITY, PAKISTAN

This study assessed water quality in Larkana by analyzing various parameters. Samples from domestic and commercial sites were tested for color, odor, turbidity, temperature, pH, conductivity, TDS, hardness, Dissolved Oxygen, iron, alkalinity, and salinity. Results indicated that some samples met WHO and PCRWR standards, while others exceeded safe drinking limits. Tap water in U-1, U-2, and U-3 residential zones was deemed satisfactory, but further research on other pollution sources, including chemicals and microbiological agents, is essential. The study suggests a need for extended investigations, potentially involving human bodily fluids, to comprehensively evaluate water quality in Larkana.
