Abstract:
Groundwater pollution is concealed, and the pollution process is slow and difficult to manage. In recent years, China has attached great importance to the protection of groundwater environment. The research on groundwater pollution source analysis technology, which supports the protection concept of ‘prevention first’, has become a research hotspot in the field of groundwater pollution prevention and control. This paper introduces the
main technical methods of groundwater pollution source analysis at home and abroad, including isotope method, fluorescence spectroscopy, geological statistics, principal component analysis, positive matrix factorization, self-organizing mapping technology, the basic principles of these six common methods and their application and research dynamics in the field of groundwater pollution identification, summarizes the advantages and disadvantages and applicability of the methods, and looks forward to the application prospects and development trends of the above methods in the research of groundwater pollution.
