Heavy Metal Concentration in underground water due to Fly Ash at Janjgir Champa region in Chhattisgarh

Abstract

The present study focused on the groundwater contamination due to fly ash disposal of coal-fired thermal power plant into a non-liner ash pond. Tendubhata were selected as study site around ash pond of Marwa thermal power plant. Groundwater samples were collected on random basis using composite sampling method. Ten heavy metals (Ca, Cu, Cd, Cl, Zn, Pb, Ni, Cr, Mn, and Fe) were detected in coal, fly ash, and groundwater samples. Heavy metal concentration in coal and fly ash was assessed by Energy Dispersive X-ray Fluorescence, while AAS was used for groundwater assessment. The observed results revealed the exceeding value of heavy metals prescribed by WHO for groundwater.
