Drinking water samples were collected at consumer end from 31 various locations for physico-chemical and biological analysis. Major Chemical parameters like were pH, Electric Conductivity (EC), Total Dissolved Solids (TDS),Total Suspended solids (TSS), Total Solids (TS), alkalinity, phosphate (PO4-3), nitrate (NO3-), sulphate (SO4-2), chloride (Cl-), total hardness, calcium hardness (Ca+2), magnesium hardness (Mg+2), sodium (Na+)and potassium (K+) were analyzed. Results of the study showed that all the parameters were inpermissible limits except pH (8.7) and total suspended solid (TSS) (29.7). Both pH and total suspended solid (TSS) were found exceeding the recommended level addressed by WHO and Pakistan water quality standards. On other hand, biological contamination was found to be in the form of total coli form and E.colithat makes the water of the study area unsuitable for drinking and is causing major health implications such as diarrhea, dysentery, cholera, hepatitis etc.Article
