Determination of Physico-Chemical Parameters and Water Quality Index (WQI) of Sapana Dam Water at District Betul (M.P.)

The present investigation was carried out to evaluate the water quality index (WQI) of Sapana dam water located at District Betul (M. P. ) along with the analysis of various physico-chemical parameters such as pH, Turbidity, Electrical Conductivity (EC), Total Hardness (TH), Total Alkalinity (TA), Total Dissolve Solids (TDS), Chloride, Nitrate, Oil& Grease, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). The WQI of any water body is a single number that indicates the water quality of whole water body in the form of single value and presents useful information of overall quality of water for public or for any other utilities as well as in the pollution abatement programme and in water quality management. The calculated values of WQI for all four sampling stations collected from Sapana dam in the first week of every month of Jan.2020 to Mar.2020 were recorded as 48.75, 47.71, 44.57 and 43.85 respectively. On the basis of calculated WQI values and analysis of studied physico-chemical parameters, the results reveals that the quality of Sapana dam water falls under Good category and can be used for domestic and irrigation purposes after some proper and necessary treatment.
