Groundwater, since long has been utilised as a perennial source of water in Bundelkhand area especially for drinking and irrigational purposes. The present study analyses physico-chemical parameters of 14 groundwater samples collected across Birma river basin, Hamirpur and Mahoba district, Uttar Pradesh viz. pH, electrical conductivity(EC), Alkalinity, Total dissolved solids(TDS), Biological oxygen demand(BOD), chemical oxygen demand (COD), Total hardness(TH), Turbidity, Calcium(Ca2+), Magnesium(Mg2+), sodium(Na+), Potassium(K+), Bicarbonates(HCO3-), Sulfate(SO4-), Nitrate(NO3-), Chloride(Cl-), Fluoride(F-), Iron to analyse groundwater quality. Based on these parameters water quality index (WQI) has been calculated for classifying the area into excellent, good, poor, etc. It ranges from 19.99 to 79.30. In general, the WQI of the study area shows good quality of groundwater and is suitable for drinking purpose excluding localities of Akauna, Bilgaon, Dhanauri and Kulpahar where it has been classified under poor category. Hill-Piper Trilinear diagram shows dominance of Ca-Na-HCO3 type in the area signifies geogenic contamination of Na and Ca bearing salt/minerals and implications of anthropogenic activities. This study aims to provide useful input to the strategy makers for judicious ground water management especially for the areas where ground water has been estimated unfit for human consumption without proper treatment.
