Contaminants can enter the human body through drinking water or soil plant systems via the food chain, directly endangering human health. There are two main sources of organic pollutants in soil and groundwater, one being naturally produced in nature. Generally, in the geologic junction layer existing in nature, which is in contact with groundwater for a long time, a variety of organic pollutants are naturally produced, the most important component of the pollutants is humic acid, and the longer they exist, the more serious the pollution caused to soil is. The other is from organic pollutants brought about during human activities. The pollutants are not only widely distributed, but also quite complicated in formation reason. Organic pollution of soil and groundwater may also occur due to pollution caused by oil leakage during oil extraction and crude oil transportation, or due to the messy discharge of sewage from some production enterprises that do not comply with regulations.
