Abstract

In the present study, water quality of groundwater has been assessed in terms of water quality index (WQI) in Ballia district of Uttar Pradesh. Data of 12 groundwater samples each of hand pump and bore well was taken for computing the Water Quality Index using eleven parameters viz. pH, Total Dissolved Solids, Turbidity, Total Hardness, Arsenic, Fluoride, Chloride, Nitrate, Iron, Sulphate and Dissolved Oxygen. The WQI results show that the overall water quality class is ‘fair’ and water needs treatment.
