  • Description: Objective Volatile organic compounds (VOCs) can exist in groundwater for a long time, thus causing harm to human body. Methods To characterize the volatile organic compounds (VOCs) pollution in the organic-contaminated phreatic zone beneath a decommissioned oil refinery in Northwest China, investigations and sample testing were carried out and possible health risks were assessed in the study area. Results A total of 18 VOCs were detected in the groundwater at the site, with detection rates ranging from 6.25% to 56.25%. Benzene and 1, 2, 4-trimethylbenzene were the main characteristic pollutants, with adetection rate being 56.25%, both of which exceeded the class Ⅲ standard of the Groundwater Quality Standard (GB/T14848-2017) in China by 50%. The pollutants at the site mainly originated from the vertical seepage from the former liquefied gas storage tank area and the former diesel oil irrigation area, indicating that these two areas may be the main pollution sources of groundwater at the site.
