Five samples of drinking water (DW) were taken from five different academic institutes of District Vehari, Pakistan which are; Sample-1 from University of Education Vehari Campus; Sample-2 from Government Post Graduate College for Women Vehari; Sample-3 from Government Post Graduate College for Women Vehari; Sample-4 from COMSATS Institute of Information Technology Vehari Campus and Sample-5 from BZU Vehari Campus. The analysis was qualitative as well as quantitative to determine the quality of DW, which is based on the determination of physico-chemical characteristics of DW samples. These physico-chemical characteristics are; pH, temperature, turbidity, alkalinity, total hardness, chloride ion estimation, color and taste. Different chemical tests and techniques were applied to determine the water quality. After that, the results obtained from these experiments indicated that Sample-2 is very polluted with large amounts of salts which cause its hardness and made it unfit for drinking purposes, because this hardness causes health diseases in humans. The Sample-3 contains large amounts of chloride ions which hardened it, as its temperature is also low. Except Sample-3, all other four samples are not much polluted and are fit for drinking. So, author recommended leaving the use of Sample-3 of water of Government Post Graduate College for Boys Vehari.
