Abstract

In India, there is a great concern for toxic trace elements contamination of surface water and groundwater due to leaching from the huge ash ponds situated in and around the water resources of the country. Accumulation of these residues in ponds for long makes the groundwater vulnerable to metal contamination due to leachate percolation. This paper addresses some of the environmental problems that our society has been facing due to disposal and improper handling. A scientific study has been carried out on chemical characteristics of CCRs using a dispersion modeling for predicting the concentrations of toxic trace elements in different ages from the piles of fly ash in the dump yard. The results have proved that the toxic elements are washed away from the morphological area of fly ash particles. The concentrations significantly comes to very low so that the scope for its 100% utilization in resolving many environmental issues in mining industries. This paper also emphasizes that CCRs can be gainfully utilized as a backfill and stowing materials in mining areas which offers immense potential of accommodating huge amount of CCRs. Further this paper also brings out CSIR-CIMFR’s never-ending efforts in going for innovative use of CCRs in solving this disposal and handling issues in bulk. Though of late it has been proved that CCRs can act as a resource material if handled properly and judiciously it is still time when we can place ourselves fully to the true picture of 100% utilization of the materials in a safe and environmentally benign manner.
