The result indicates that the average concentration of the pollutants are respectively as follows: As: 0.004mg/l, Hg: 0.001 mg/l, Cr6+: 0.005～0.015 mg/l, Pb: 0.01 mg/l, Cd: 0.005 mg/l, F: 0.01～1.4 mg/l. Among the non-carcinogenic health risk in the research areas caused by the drinking water, the Pbs risk is the biggest, followed by F and Hg which risk level is 10-8 /a～10-10 /a; the carcinogenic risk caused by Cr6+ is the biggest, reaching 10-4/a, and meets the EPA requirement, but is higher than the maximal risk level that International Commission on Radiological Protection (ICRP) can accept.
