A Preliminary Study on Shallow Groundwater Organic Pollution in the Alluvial Plain of Hutuo River

摘要

Groundwater is the source of main agricultural, industrial and domestic water in the Alluvial Plain of Hutu River, the pollution degree of groundwater directly affectshabitants¡¯ state of health in the area. In order to explain the condition of shallow groundwater organic pollution under the influence of human activities, the Alluvial Plain of Hutuo River was selected as the main study area, and then by a large amount of groundwater sampling, analysis and test, we analyzed the characteristics of shallow groundwater organic pollution. The results show that shallow groundwater has been under threat of organic pollution in the area, the main detected organic components are halogenated hydrocarbons, polyaromatics and chlorobenzenes, among which the detection rate of trichloromethane amounts to 14.02%; Over-standard organics samples are sparse, but the over-standard concentrations are high, the main over-standard component istetrachloro methane. Because of the high toxicity of organics, organic pollution has become unable to be neglected in the study area.
