Application of Geophysical Exploration Technology in the Investigation of Contaminated Sites
Taking a tributary polluted by heavy metals in the upper reaches of the Yellow River as an example,the application of electromagnetic induction method and high-density resistivity method in the investigation of contaminated sites was studied.The electromagnetic induction method has the ability to quickly investigate the distribution of heavy metal soil pollution with obvious electrical differences,and the high-density resistivity method can be used to quickly investigate the extent and depth of soil pollution.According to the characteristics of different contaminated soil and the status of waste burial,the combination of the two can be used to rationally plan the spacing grid density,effectively and accurately identify the depth and scope of contaminated soil,and provide reasonable technical assistance for contaminated soil site investigation.
