In Skardu and other northern area, demand for drinking water is met through both surface and subsurface water. No survey regarding the potability of water has been conducted in the past. Considering the importance of this survey, ten samples of drinking water from different sources were collected and analyzed for various parameters like pH, dissolved oxygen, electrical conductivity, suspended solids, alkalinity, hardness, nitrites, sulphates. chlorides, sodium, and potassium. They are also analyzed for heavy metals like iron, chromium, zinc, manganese. copper, nickel, cobalt and lead using atomic absorption spectrophotometer. The magnitude of different trace metals followed the order Zn > Fe> Ni > Pb> Co > Cu > Cr. Analysis indicate that there was no collinearity among the metals.
