The water quality of Pauri District of Uttarakhand, India has been assessed during pre- and post-monsoon seasons to express the suitability of water for drinking purposes. The values of turbidity and iron exceed the permissible limit prescribed by Indian Standards for drinking purpose. Some sites were also contaminated with large number of total and fecal coliform bacteria. Piper diagrams exhibit that all water samples fall in Ca-Mg-HCO3 hydrochemical facies and show the nature of carbonate hardness during both seasons. Based on the seasonal variation, the concentrations of most of the parameters considerably decreased during post-monsoon season and show the dilution effect of rain water in monsoon season. Water quality index describes the suitability of all sources for drinking purpose with ‘Good’ and ‘Excellent’ water quality during pre- and post-monsoon seasons, respectively.
