Assessment of Indicator Parameters to ...

Groundwater quality of Chandrapur district was assessed in pre and post monsoon season based on the physicochemical parameters, biological parameters and water quality index. The water quality index was calculated using indicator parameters viz., pH, turbidity, temperature, nitrates, total phosphate, dissolved oxygen, biochemical oxygen demand, total solids, faecal coliforms with respect to its different uses like residential and commercial, as well as indicator parameters, in addition, index value was compared with quality rating to examine the seasonal variation in groundwater quality. The water quality index was observed from 74.0 to 83.0 and 63.0 to 78.0 in pre and post monsoon season, respectively. Our finding indicates that 100 percent (70 samples) groundwater samples were of desirable quality in pre monsoon season but 30 percent (21 samples) of all showed the quality change from well to less fair in post monsoon season, this seasonal variation in water quality rating has indicated the deterioration of water quality in the study area, thus indicating a need of proper treatment before use.
