This study investigates seasonal various physicochemical parameters in river water samples of Parwan were collected from 10 sampling sites in Jhalawar District, India during three seasons (summer, rainy and winter) throughout the one year of November, 2010 to October, 2011.The physico-chemical parameters like pH, turbidity, total dissolved solids, total hardness and concentrations of ions like chloride, fluoride, nitrate and sulphate were analyzed to know the present status of the river water quality. The results were compared with the drinking water standards of ISI (10500-91) and WHO (1973). It was found that the river water was contaminated at few sampling sites therefore needs to be treated if it is to be used at all. The remaining sampling sites shows physicochemical parameters within the water quality standards and the quality of water is good and it is fit for domestic uses, drinking and agricultural purposes.
