This study investigates the groundwater quality of Singrauli power belt region in Central India. Ground water samples were collected from 54 representative sites during pre and post monsoon seasons and analysed for pH, EC, TDS, TH, major ions (Na 2+ , K + , Mg 2+ , Ca 2+ , SO 4 2-, NO 3-, F-, Cl-) and heavy metals (Fe, Cr, Mn). Groundwater samples dominantly belonged to Ca-Mg-HCO 3 water type. Gibbs ratios indicated that rock weathering is the major driving force for controlling the groundwater chemistry. Ca 2+ , Mg 2+ , Na + , K + , HCO 3-, Cl-, SO 4 2concentrations in the groundwater were well within the permissible limits as recommended by WHO for drinking water. A total of 35% and 44% of the samples during post and pre monsoon season, respectively, had exceeded the Fconcentrations compared to WHO recommended limits of 1.5 mg/ L. Likewise, a total of 22% and 26% of the samples had exceeded their regulatory limits of NO 3 i.e., 45 mg/L during post and pre monsoon seasons, respectively. High fluoride in groundwater near fly ash ponds indicated contamination through leaching from ash ponds. High NO 3 could be attributed to the formation of nitrogen oxides during coal combustion, their deposition on the surface and subsequently leaching to groundwater. Majority of samples had Fe and Cr concentration exceeding the WHO permissible limits, thus rendering water unfit for drinking purpose. Parameters like percent sodium (%Na), electrical conductivity (EC), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), magnesium hazard (MH) permeability index (PI), chloroalkaline indices (CAI) and Kelly's index suggest that majority of groundwater samples were good for irrigation purpose. The USSL plot suggested that majority of groundwater belonged to C 3 S 1 class, representing high salinity hazard and low alkali hazards water, which requires proper drainage otherwise it can adversely affect the soil.
