Temporal Variation in Water Quality around the Korba City of Chhattisgarh

Korba city is situated on the banks of the confluence of rivers Hasdeo and Ahiran. Korba is the power capital of Chhattisgarh. Ground water is the main sources of drinking water in the district. To know the suitability of water for domestic use, water samples were collected from 62 different locations. These collected water samples were analysed for the physicochemical parameters (Temperature, pH, Conductivity), major ions (Ca, Mg, Na, K, CO3, HCO3, Cl, SO4, F) Total Hardness (TH) and Total Alkalinity (TA) and heavy metals (Fe, Mn, Pb, Cu, Zn, Cr). To see the suitability of water quality for drinking purpose the obtained values are being compared with BIS (10500: 2012) drinking water standards. The hydro chemical analysis results reveals that the ground water is mild alkaline in nature and of low conductivity value. The concentration of all major ions calcium, magnesium, sodium, potassium, carbonate, bicarbonate, chloride and sulphate are generally found within the limit set by BIS and ground water of shallow aquifer is moderately hard in nature. The occurrence of high nitrate, fluoride and heavy metals in some of the groundwater samples has also been observed. The changes with time the water quality results were compared with the previous studies and this temporal variation around the industrial city, Korba, has been described in the present paper.
