%X Based on the evaluation method for health risks of contaminated sites recommended by USEPA, in combination with the actual situation of the contaminated site, the authors analyzed and evaluated the health risk of groundwater organic pollution at a certain oil depot. The result shows that the organic pollutants in groundwater of the oil depot include 1,2-dichloroethane, benzene, chloroform and toluene. The non-carcinogenic risk suffered by the workers and residents in the contaminated site is less than 1, which is in the acceptable range. Nevertheless, the workers and residents in the contaminated site suffered a relatively high cancer risk, being 1.7×10-4 and 9.0×10-3, respectively, which are unacceptable. The 1,2-dichloroethane is a major pollutant of carcinogenic risk, accounting for 99.80% of the total cancer risk. It may cause many forms of cancer, and has the potential genetic toxicity. The main exposure way is the inhalation absorption, which accounts for more than 70% of the total cancer risk, followed by oral absorption. The carcinogenic risk via the dermal pathway is negligible, which is less than 1% of the total cancer risk.
