Through the testing, research and analysis of the 390 samples of shallow groundwater in Hutuo alluvial plain, this paper illustrates the pollution characteristics of high Chloroform detection rate and wide distribution, through analysis obtains the conclusion that the main pollution sources are industrial enterprises and sewage drainage rivers and channels, determines the distribution of pollution sources and makes clear that the direct cause affecting the halogenated hydrocarbon pollution in the region is the lithology of the unsaturated zone. In addition, the GUS value of Chloroform is calculated through EPI S uit, and the leaching migration is preliminarily discussed.
