Migration of contaminants from waste disposal sites to surrounding ecosystems is a complex process. Soil and water contamination around ash disposal site has recently been the subject of much research world over. Trace elements present on the surface of ash particles are readily leached and tend to contaminate the groundwater. Toxicity of surrounding ecosystem results due to increase in metal concentrations beyond their threshold values. Groundwater pollution due to landfills has been studied. It also studied that groundwater contamination index was used for mapping the degree of contamination. In this article, contamination of soil, water and air with special reference to fly ash has been discussed.
Key words: Soil, Water, Air, Fly Ash
