Abstract:

The classification and identification of groundwater pollution sources is essential for groundwater pollution prevention and control. The typical groundwater pollution sources were studied and the major groundwater pollution sources identifying index system established based on the priority control contaminants and pollution sources characteristics analysis results. The pollution sources hazards assessment results were regarded as the basis for the major groundwater pollution sources identification. The Hasse diagram method and comprehensive evaluation method were applied to identify priority control contaminants, and the revised Nemerow Pollution Index introduced to comprehensive assess the multicomponent priority control contaminants. Three typical groundwater sources were selected to verify the method. The results showed that the hazard level of S1, S2 and S3 was Ⅲ, Ⅲ and Ⅱ, respectively. Thus, in the management of regional groundwater pollution sources, more attention should be paid to the sources with high levels of hazard pollution, such as S1 and S2.

Key words: groundwater, pollution source, priority control contaminants, hazards assessment, classification and identification
