Abstract: The present study is to assess the underground drinking water quality at Moradabad with special reference to a number of water quality physico-chemical parameters at some prominent public places. Seasonal variation of water quality is also studied by analyzing the drinking water quality qualitatively as well as quantitatively for the three major seasons of the year namely summer, rains and winter. Fifteen different physico-chemical parameters are estimated at five public places with large footfall. It is observed that water with reference to most of the parameters studied is polluted in the catchment area under observation. Certain parameters showed seasonal trends while others stayed in the polluted range. It was found that underground water cannot be used without prior treatment at most sites throughout the year. Proper treatment procedures should be implemented immediately to ensure supply of clean drinking water.

Keywords: Underground water, Water quality, Seasonal variation, Physico-chemical parameters.
