Assessment of Quality and Pollution Potential of Groundwater around Dabhaura Area, Rewa District, Madhya Pradesh, India

摘要

The present paper deals with quality and pollution potential of Groundwater of Dabhaura area, Rewa District, Madhya Pradesh. The study area is mainly drained by Jatari river which finally meets to Tons river, a life line of Rewa region. Geologically, the area is occupied by shale and Govindgarh sandstone formations of Upper Vindhyan. A total of 22 groundwater samples from shallow aquifer zone collected in June 2011 and analyzed to see their suitability for drinking and irrigation purposes. The analysed data reflect that the groundwater of the area is moderately hard to very hard, higher amount of total dissolved solids as well as higher concentration of sulphate due to lithology of aquifers. A most of samples are within prescribed limits as suggested by World Health Organisation (WHO) and Indian Standard (ISI) for drinking purpose. The groundwater is mainly Ca-Mg-SO 4 -Cl and Ca-Mg-HCO 3 type. The plot of electrical conductance (EC) vs sodium adsorption ratio (SAR) of analysed groundwater samples in U.S. salinity diagram indicating them to be of medium to high salinity and low sodium hazard type of groundwater. However, for the computation of vulnerability, the DRASTIC Index (DI) modelling has been adopted. The computed Drastic Index suggests that the area is moderate to high susceptible to pollution. Hence, proper attention and water quality monitoring programme has been suggested to check the groundwater pollution.
