Evaluation of Physio-chemical Properties and WQI of the Drinking Water in Urban Area of Bilaspur, Chhattisgarh, India

This study was estimating the physicochemical parameters of water and preparing the water quality index for drinking water in a residential area of Bilaspur city. Fifty water samples were collected from ten sites and analyzed six parameters of water quality by using the portable multi-parameter water quality meter (Hanna Instruments: HI98194). The results of water quality were statistically different for sites (p<0.001). During the study, the average water pH (8.326±0.67), water temperature (27.349±0.207 °C), dissolved oxygen (7.775±0.034 mg/l), total dissolved solids (526.46±0.781mg/l), electrical conductivity of water (391.6±0.79 mg/l), and oxygen reduction potential (-32.715±0.21 mV) were recorded. The positive correlation was observed between EC and TDS (r = 0.935) and pH and ORP (r = 0.802), while the negative correlation was observed between DO and temperature. The range of the WQI was observed to be 383.67 to 530.87, and there was a statistically difference at for sites (p<0.001).
