ABSTRACT
The aim of this study was to perform physico-chemical and microbial analysis of drinking water samples of different areas of Rawalpindi. The water samples were collected into sterile containers from the different localities of Rawalpindi such as Dhokekala khan, Morgah, Scheme-III, Gulshandadan khan, Satellite town, Dhoke kashmirian, Pandora, Bahria town, University campus (Mehr water) and Air Port. The pH of PMAS-AAUR campus water ( Mehr Water) was found within WHO recommended values (pH limit 6.5-8.5) whereas the pH of other water samples were ranged from 7.3-8.9.The salts values of Mehr Water were determined as Calcium 58mg/l, Sulphate 48mg/l, Sodium26mg/l, Magnesium13mg/l,Chloride150mg/l, Alkalinity 147 mg/l and total dissolved solids176mg/l were found according to WHO recommended limits. The values of Calcium 89mg/l, Magnesium 52mg/l, Chloride 342mg/l, and ions like Sulphate 412mg/l of Dhokekala khan, Morgah, Scheme-III, and Bahria town, respectively were not found according to WHO and PSQCA recommended limits. The Microbial analysis of Mehr water showed that water was free of mould, yeast, E.coli, total coliform and bacterial contamination. The water samples of Dhoke kashmirian, Pandora Satellite town, and Gulshan dadan khan indicated coliform, yeast and bacterial contamination which caused water-borne diseases such as Dysentry, Diarrhea and Typhoid fever.
