Comparative study of microbiological and physico-chemical parameters of abandoned coal void of Jharkhand, India


Author(s): AK Singh, Anubhuti Kumari and Surya Kant Bhatta

Abstract: Coal void is a surface pit developed after open cast mining which get filled with rainwater. It has less surface area and great depth as a result poor water mixing and strong thermal and dissolved oxygen stratification. These characteristics make it different from natural water bodies. The physic-chemical and bacteriological parameters studied revealed that water temperature ranges 7 to 27 0C, pH 7.8 to 8.8, Conductivity 538 to 1446 mhos, TDS 468 to 1258 ppm, Dissolved oxygen 3.6 to 12.4ppm, Carbon dioxide 4.4 to 13.2ppm, Alkalinity 109 to 151 ppm, chloride 22 to 31ppm, Hardness 256 to 860ppm, COD 30 to 42ppm, BOD 1.4 to 2.0ppm, Nitrate 1.1 to 1.98ppm, Ammonical nitrogen 0.18 to 0.29ppm, Phosphate 0.7 to 2.0ppm, Organic carbon 2.8 to 5.7ppm and TSS 81 to 999ppm. The bacterial load ranges from 0.63x103 to 9.222x103. It is more in one of the coal void which receives organic matter from runoff.
