In this study, we monitored 4 volatile organic compounds (VOCs) such as chloroform, dichloromethane, 1,2-dichloroethane, and tetrachloromethane in groundwater samples to determine the detection frequency and their concentrations and evaluated the health risk level considering ingestion, inhalation, and skin contact. 75 groundwater wells were selected. 24 wells were from monitoring background groundwater quality level and 51 wells were from monitoring groundwater quality level in industrial or contamination source area. In the results, the detection frequency for chloroform, dichloromethane, 1,2-dichloroethane, and tetrachloromethane was 42.3%, 8.1%, 6.0%, and 3.4%, respectively. The average concentrations of VOCs were high in the order of chloroform (1.7 μg L<SUP>-1</SUP>), dichloromethane (0.08 μg L<SUP>-1</SUP>), tetrachloromethane (0.05 μg L<SUP>-1</SUP>), and 1,2-dichloroethane (0.05 μg L<SUP>-1</SUP>). Chloroform had the highest detection frequency and average detection concentration. In the contaminated groundwater, the detection frequency of VOCs was high in the order of chloroform, dichloromethane, 1,2-dchloroethane, and tetrachloromethane. The average concentrations for chloroform, dichloromethane, 1,2-dichloroethane, and tetrachloromethane were 2.23 μg L<SUP>-1</SUP>, 0.08 μg L<SUP>-1</SUP>, 0.07 μg L<SUP>-1</SUP>, and 0.06 μg L<SUP>-1</SUP>, respectively. All the 4 compounds were detected at industrial complex and storage tank area. The maximum concentration of chloroform, dichloromethane, and 1,2-dichloroethane was detected at industrial complex area. Especially, the maximum concentration of chloroform and dichloromethane was detected at a chemical factory area. In the uncontaminated groundwater, the detection frequency of VOCs was high in the order of chloroform, dichloromethane, and 1,2-dchloroethane and tetrachloromethane was not detected. The average concentrations for chloroform, dichloromethane, and 1,2-dichloroethane were 0.57 μg L<SUP>-1</SUP>, 0.07 μg L<SUP>-1</SUP>, and 0.03 μg L<SUP>-1</SUP>, respectively. Although chloroform in the uncontaminated groundwater was detected the most, the concentration of chloroform was not exceeding water quality standards. By land use, the maximum detection frequency of 1,2-dichloroethane was found near a traffic area. For human risk assessment, the cancer risk for the 4 VOCs was 1<SUP>0-6</SUP>~10<SUP>-9</SUP>, while the non-cancer risk (HQ value) for the 4 VOCs is 10<SUP>-2</SUP>~10<SUP>-3</SUP>.
