Coal is the major fuel used for generating electricity world wide while the process of coal mining involves the discharge of huge amount of effluent into the surface water. Effluent from coal mine contains high load of TSS, TDS, calcium carbonate and heavy metals hence contaminates the aquatic regime ( Dhar et al., 1986 ).
EPA promulgated the Coal Mining Effluent Guidelines and Standards (40 CFR Part 434) in 1975, and amended the regulation in 1976, 1977, 1979, 1982, 1985 and 2002.The regulation covers wastewater discharges from mine drainage, coal storage facilities, and coal preparation plants.
