Abstract

The present work is aimed at assessing the water quality index (WQI) for the ground water of Bidar city and its industrial area. The groundwater samples of all the 35 wards were collected and subjected for a comprehensive physicochemical analysis. For calculating the WQI, the following 17 parameters have been considered viz., pH, total hardness, calcium, magnesium, chloride, nitrate, sulphate, total dissolved solids, iron, fluoride, sodium, potassium, alkalinity, manganese, dissolved oxygen, total solids & zinc. The results analyzed (by WQI method) have been used to suggest models for predicting water quality. The analysis reveals that the groundwater quality status of the study area is excellent, but it also needs to be protected from the perils of future contamination by giving certain degree of treatment viz., disinfection.
