Abstract:     The assessment of groundwater quality of dug wells of the Bhogavati river basin (latitude 160 19’45” N to 160 44’30” N and longitude 730 50’15” E to 740 11’50”E) in Kolhapur District, Maharashtra, India was carried out and 60 dug well water samples were collected. The physico-chemical analyses of these water samples reveal that 93.30% and 95% groundwater samples represent Ca+Mg (alkaline earth) hydrochemical facies in pre and post-monsoon seasons respectively, whereas, 6.70% of groundwater samples in pre-monsoon season and 5% of groundwater samples in post-monsoon season represent Ca+Mg > Na+K (alkaline earths exceed alkalies) hydrochemical facies. Similarly, 63.30% groundwater samples of pre-monsoon season and 66.70% groundwater samples of post-monsoon season represent Cl+SO4 > HCO3+CO3 (strong acid exceeds weak acid) hydrochemical facies, while 36.70% groundwater samples of pre-monsoon season and 33.30% groundwater samples of post-monsoon season belong to HCO3+CO3 > Cl+SO4 (weak acid exceeds strong acid) hydrochemical facies. On the basis of Gibbs diagram the chemistry of groundwater belongs to precipitation dominance in pre-monsoon season and rock dominance in post-monsoon season.
