Abstract: Ground water is an important resource for meeting domestic, agricultural and industrial needs. Its quality is a vital parameter for assessing the overall socio-economic development of mankind. This paper deals with the quality of 149 groundwater samples collected under Aquifer Mapping Studies in Chikballapur district of Karnataka. Due to drying up of shallow aquifers, samples were mainly collected from borewell representing deeper aquifer to evaluate its suitability for drinking purpose as per Bureau of Indian Standard (BIS), 10500:2012. Parameters like pH, Electrical Conductivity (EC), Total Hardness (TH), Calcium (Ca++), Magnesium (Mg++), Sodium (Na+ ), Potassium (K+ ), Carbonate (CO3 - - ), Bicarbonate (HCO3 - ), Chloride (Cl- ), Sulphate (SO4 --), Nitrate (N03 - ), Fluoride (F- ) and Boron (B) were analyzed. The chemical analysis results reveals that Fluoride and Nitrate in the groundwater samples are found beyond the permissible limit, probably influenced by both geogenic and anthropogenic factors respectively. Fluoride contamination is more widespread than nitrate. Hence, mitigative measures are immediately required to provide safe drinking water through appropriate management plans to achieve sustainability of the ground water resources in the area
