Hydrochemical Evaluation and Assessment Groundwater Quality through Water Quality Index Around Chandrapur Industrial Area, Maharashtra, India

Abstract: The present study focuses on assessing the current status of Groundwater quality for drinking purpose around Padoli MIDC of Chandrapur region. Stratigraphically, the area is comprising Archean granite and gneiss at base and overlain by Kamathi and Barakar sandstone of Gondwana group of rocks. For assessment of groundwater quality, total fifty-two (52) groundwater samples were collected from dug well and bore well during the post monsoon season 2022. The physico-chemical parameter like pH, EC, TDS, TA, Ca2+, Mg2+, Na+ , K+ , HCO3 - , SO4 2-, Cl- , NO3 - and F-were analysed and compared with the BIS 2012 standards. it shows that most of the well samples are within the allowable limit set by BIS, except TDS, TA, Ca and Mg. The dominance of cations and anions of the study region shows increasing abundance as Ca2+> Na+ > Mg2+> K+ and Cl- > HCO3 - >SO4 2-> NO3 respectively. Suitability of groundwater for drinking purpose is also evaluated on the basis of water quality index and hydrochemical characteristics through Piper and Gibbs plot. Based on water quality index, 64% of the well samples are favourable for drinking status. The hydrochemical facies of study area is of Mixed type and alkaline earth in nature. Gibbs diagram reveal that Evaporation is the major process for controlling the groundwater chemistry of the region.
