Abstract:
Water quality index (WQI) of groundwater based on the data of 27 samples collected from Rajkot district, Gujarat
was assessed using seven parameters viz. pH, Total Dissolved Solids, Total Hardness, Fluoride, Chloride, Sulphate and
Nitrate. The WQI value 98 is maximum and the value 27 is minimum in the study area. The computed WQI shows that
51.8% of water sample fall in the ‘good’ to ‘excellent’ water category. On the other hand, 48.2% of water samples fall
in the ‘fair’ to ‘poor’ category indicating that the water is not suitable for direct consumption and require treatment. After
treatment, the water can be used for drinking purpose.
