Transmission of many diseases occurs primarily by drinking water. These diseases are produced in the water bodies due to anthropogenic pollutants. The transport of many anthropogenic pollutants in the water is determined by their physico-chemical parameters. The current studies were to analyse the physico-chemical parameters of drinking water from natural reservoirs of the Bhiwandi city and its adjoining areas. The samples of water were collected from three natural resources viz. well, bore well and lake water. Physico-chemical parameters such as water temperature, turbidity, total dissolved solid (TDS), pH, dissolved oxygen (DO), chemical oxygen demand (COD), total hardness, electrical conductivity (EC), chloride (Cl-), sulphate (SO4 2-), sulphite (SO3 -), nitrate (NO3 -) and nitrite (NO2 -) were analyzed. All parameters were within the permissible limits except lake water. Temperatures were in the range of 26.1 – 32.8oC. All samples show the alkaline pH. Total hardness was in the ordered Lake water > Bore well water > Well water. DO was more in lake followed by well and then bore well water. EC was in the range 138 to 813 μS/cm. All samples show approximate level of NO3 - and SO4 2-. According to World Health Organization (WHO), all these above results suggested that the quality of water in Bhiwandi city and its adjoining areas is potable for drinking and useful for agriculture practices as well as industrial purposes except lake water.
