Ground water and surface water was analyzed for twenty different location of Pauri district, one of the populated cities of Himalayan region of Uttarakhand. To evaluate water quality of these sources, a study was carried during three seasons viz. monsoon, winter and summer. Sixty samples were analyzed for different physical and chemical parameters viz. Turbidity, Alkalinity, Total hardness (TH), Residual chlorine (RC), Chlorides, Fluorides, Iron and Nitrates. Results obtained were compared and correlated with standard values in Indian Standard specification (IS): 10500 along with mapping of these sources. The maximum mean value of turbidity, alkalinity, TH, RC, chlorides, fluoride, and nitrates were 12NTU in monsoon, 138.05 mg/Lin winter, 183.46 mg/L in winter,0.12mg/L in winter, 65.795 mg/L in winter, 0.25 mg/L in monsoon season, and 0.54 mg/L in monsoon season respectively.
