Baoji City's drinking water sources include Fengjiashan Reservoir, Qingjiang River and some wells. In order to fully grasp the water quality safety status of drinking water sources in Baoji City, the content and health risk assessment of drinking water from heavy metals in water sources were carried out. The results showed that: the content of heavy metals in drinking water of major water sources in Baoji City was within the limits of the national standards, but the maximum Pb concentration exceeded in the major drinking water sources in Baoji City. The mean value (well water, Qingjiang River, and Fengjiashan Reservoir was 35, 43.92, 47 μg/L) were close to the national standards. The risk index of drinking water in drinking water sources in Baoji City was between 4.75×10-4 and 6.84×10-4, and the non-carcinogenic risk was between 1.05×10-7 and 3.25×10-7. The order of the carcinogenic risk caused by heavy metals was Cr >As>Cd>Ni, the water quality of children in major drinking water sources in Baoji City was slightly greater than the risk of adult health and should be taken seriously. The health risks of major drinking water sources in Baoji City showed that the spatial distribution pattern of well water>Qingjiang River water>Fengjiashan Reservoir water. The water quality of drinking water sources in Baoji City met the standard, but the health risk risk exceeded the threshold recommended by the relevant international organizations, and the risk of cancer-causing health was the main one, among which Cr was the main risk factor.
