Detection of the Typical Organic Contamination in Groundwater and Discussion of Characteristics of Groundwater Pollution
The typical organic contaminatants in groundwater include aromatics compounds,halogenated hydrocarbon compounds,and pesticide compounds and so on.In general,the organic contamination in groundwater is transferred by absorption,volatilization,hydrolysis,photolysis,bioenrichment and biodegradation.The data from two hundred and seventy-seven points which are typical groundwater pollution place in the country.VOC,PAHS were found in about eighty-five samples.The discussion of this paper focuses on the physical-chemical property of the organic contamination which are Henrys constant and Partition Coefficient (n-octanol/water).According to the organic contamination of chlorinated hydrocarbon whose concentration is significantly the factor of the transport of them in groundwater were discussed.At the mean time,because people dont consider the influence of the physical and chemical properties of the organics in the used DRASTIC model1,this paper will make more cognition in the condition of organic contamination in the groundwater.
