In the present study, data of 41 hydrograph stations distributed in the Haridwar district are analysed for the years 2014-15 for depth to water level and water quality. The average depth to water level during pre-monsoon is found 10.74 m and in post-monsoon there is a rise of 0.23 m in average water level and found 10.51 m. Among all the 6 blocks viz. Bhagwanpur, Bhadarabad, Khanpur, Laksar, Narsan and Roorkee, the distribution of water level shows that the water levels are deep in the entire Bhagwanpur block. For assessing the groundwater quality, the water samples were collected from 40 sites covering the entire district. The groundwater is formed as Ca-Mg-HCO3 type. In the groundwater, alkaline earths exceed the alkalis and weak acids dominate strong acids. Although groundwater quality is good for drinking as well as irrigation purpose but in few samples higher concentrations of NO3-, Cl and SO42ions are found and hence continuous monitoring is required for these ions as precautionary measures.
