Hydrochemical study of surface and ground water were performed for determining its suitability for drinking, industrial and agricultural purposes. In this study, the evaluation of various physico-chemical parameters such as pH, EC, TDS, bicarbonate and alkali metals (Na, K, Ca and Mg) of the surface and ground water has been carried out in selected sites of Dehradun using advanced analytical techniques. All results were compared with the standard limits as per WHO guidelines for drinking water and were accessed stastitiscally. The deterioraton in the quality of the water could be accounted to rapid urbo-industralization activities, increase in population with change of life style, excess use of chemical fertilizers, pesticides in soil to meet the increasing demand in the market, destroyed the water quality of ecologically rich state of Uttarakhand, India.
