Gold processing activities of artisanal gold mining at Krueng Kalee Village is using a method called amalgamation. Amalgamation method is a process of binding the gold metal from gold ore by using mercury in a tromol tube. The waste from the amalgamation process is released directly to the environment without any waste processing and caused contamination to the well water. This study aimed to determine the level of risk to mercury at Krueng Kalee community through health risk assessment approach. This study using purposive sampling as sampling method. Measurements were made by measuring the mercury concentration in the well water and anthropometry measurement community is weight. The default factor value is applied to the calculation of the exposure frequency. Non carcinogenic health risks are expressed by Risk Quotients which is obtained by divinding the intake with reference dose. The result showed that the mean concentration of mercury in the well water is 0,0032 mg/L which means that the concentration of mercury in the respondent`s well water has exceed the regulatory of health minister on water requirement where the mercury maximum allowable level in drinking water is 0,0001 mg/L. Value of Risk Quotients is greater than 1 which means that the Krueng Kalee community are at risk of non carcinogenic health disorders and assuming that mercury exposure comes from only contaminated well water and do not take to account mercury exposure from other sources .
