Aim: The present study was undertaken to determine the physico-chemical properties and heavy metals in drinking water samples collected from different sources in and around Ranchi, Jharkhand, India. Materials and Methods: A total number of 100 water samples were collected from different sources like hand pumps (44), wells (27), taps (20), rivers (3) and ponds (6). The gross appearance, taste, odour, temperature, pH, dissolved oxygen, biochemical oxygen demand, alkalinity, conductivity, total dissolved solid, salinity and the concentration of lead and cadmium were analyzed. Results: Water samples were transparent, odourless and taste was agreeable except rivers and ponds. The mean value of temperature (24.8&#177;0.416 to 30.7&#177;0.819), pH (6.4&#177;0.1 to 7.3&#177;0.1), dissolved oxygen (3.9&#177;0.05 to 8.95&#177;0.15), biochemical oxygen demand (2.3&#177;0.7 to 7.5&#177;0.409), alkalinity (35&#177;1 to 144.75&#177;40.359), conductivity (83&#177;1.15 to1508&#177;0), total dissolved solid (73&#177;1 to 1422&#177;0) and salinity (0.016&#177;.014). Mean levels (ppm) of lead (Pb) was (0.01&#177;0.00 to 0.11&#177;0.03) and cadmium (Cd) was (0.04&#177;0.01 to 0.11&#177;0.03). Conclusion: Out of water samples collected from above mentioned sources, samples from ponds and rivers were highly contaminated. The pH of 6 water samples was more than prescribed level, dissolved oxygen in 11 was samples was below than 5 ppm, biochemical oxygen demand in 19 water samples was above 6 ppm, alkalinity in 14 samples were above 120 ppm, conductivity in 2 water samples were above1400 &#956;S/cm, The levels of lead and cadmium was more than the permissible limits.
