To determine the pollution condition of aluminum in drinking water and guide the safe use of drinking water.Through ICP-AES method to determine the aluminum content in drinking water

and calculated the over-limit ratio comparing with standards（0.2 mg/L） in China（GB 5749—2006）. Furthermore

health risk was evaluated caused by aluminum in drinking water through health risk assessment theory

and probability assessment was carried by Monte carlo simulation.Aluminum in drinking water of the four villages exceed the standard

and three of them the over-limit ratio was high（>70%）.Probability assessment results showed that less than 10% of the population would have the non-carcinogenic risk

also indicating that the non-carcinogenic risk lead by Al was low.
