Assessment of groundwater in Karha river basin area Baramati, Maharashtra, India was completed in two different seasons pre-monsoon (summer) 2018 and post-monsoon (winter) 2018 by collecting seventeen groundwater samples. The study of water quality index in karha river basin area has particular importance because of geological variations. The various physicochemical parameters such as pH, EC, Ca2+, Mg2+, Na+, K+, Total dissolved solids, HCO3-, Cl-, SO42-, NO3-, F-, PO42-, DO and BOD were determined using standard procedures of APHA. Six parameters namely pH, TDS, Phosphates, Nitrates, Dissolved Oxygen and Biochemical Oxygen Demand were considered to compute Water Quality Index based on National Sanitation Foundation (NSF - WQI). WQI is an excellent management and general administrative tool in communicating water quality information. NSF - WQI calculator was used to calculate the water Quality Index. Our findings highlighted the deterioration of water quality in certain parts of study area because of arid to semi-arid conditions. According to NSF - WQI ranking 59 – 65 % water samples were good to excellent quality for drinking purpose, 18 – 24 % water samples were medium quality while 18 % samples were bad and it was not suitable for drinking purpose. They may be used for drinking purpose after suitable treatment.
