The present work focuses on the evaluation of groundwater for drinking purpose in relation to Arsenic (As) and Fluoride (F-) contamination. 17 groundwater samples were collected and analysed for major ions, As, F-, and Fe. Hierarchical cluster analysis (HCA) suggested reductive dissolution of Fe (hydr) oxides responsible for As release in the area. Association of Fluoride (F-) with both phosphate as well as silicate minerals in the post-monsoon season revels that released of F- from both phosphates as well silicate minerals like apatite and phyllosilicates respectively. Arsenic concentration appears to be dependent on depth in both the seasons. Non-cancer health risk from both As-F- was highest in children, followed by adult males and females. Hazard indices (HI) revealed that children (3-8 years) were at greater health risk than adults. Thus, the new generation seems to be at higher risk.
