Abstract: Groundwater is essential for any life support system. It is not only basic need for human existence but also a vital input for all development activities. The present hydro-geochemical study was confined to Budhgaon, Kavalapur and Karnal villages of Sangli district, Maharashtra (Lat.160 52’30’’N to 160 54’30’’N and Long.740 33’45’’E to 740 37’30’’E). Groundwater quality and its suitability for drinking purpose were examined by physico-chemical analysis of 56 dug well water samples. These parameters were used to assess the suitability of groundwater for drinking purpose by comparing with the WHO and ISI. These analyses reveals that the groundwater is not entirely fit for drinking with respect to Hardness, EC, Ca, Cl, Bicarbonates, Sodium and Sulphate. The physico-chemical analysis of these samples reveals that 98% groundwater samples of pre-monsoon season and 70% groundwater samples of post-monsoon season represents Na+K>Ca+Mg(alkalies exceed alkaline earth) hydrochemicalfacies. Similarly, 100% groundwater samples of pre-monsoon season and 84% groundwater samples of postmonsoon season reveals Cl+SO4> HCO3+CO3 (strong acids exceed weak acid) hydrochemicalfacies. The 2% and 30% groundwater samples of pre-monsoon and post-monsoon seasons suggests Ca+Mg>Na+K (alkaline earths exceed alkalies) hydrochemicalfacies respectively. The 16% groundwater samples of post-monsoon season represent Cl+SO4 (strong acids) hydrochemicalfacies. The chemistry of groundwater samples belongs to evaporation dominance (46%) and rock dominance (54%) of pre-monsoon season and evaporation dominance (64%) and rock dominance (36 %) of post-monsoon season
