**Preface to "Advances in Soil Pollution and Geotechnical Environment"**

Soil pollution and disposal technology is currently a hot topic in geo-environmental engineering that involves the interaction of mechanisms, migration processes, and treatment measures of various types of pollutants (e.g., heavy metals, organic pollutants, acid or alkali substances, and radioactive materials) with geotechnical media, as well as heat flow processes and thermal damage. Application areas include industrial pollutant treatment in shallow seepage, groundwater exploitation, geothermal resource development, thermal energy storage, waste disposal in metal mining, and landfill leachate barriers.

This Special Issue on: "Advances in Soil Pollution and the Geotechnical Environment" addresses the most recent developments in soil pollution and restoration, contaminant hydrology, and ground disturbance to stimulate fruitful technical and scientific interactions between professionals.

A total of thirteen papers in various fields of soil pollution and the geotechnical environment, including soil pollution, soil restoration, and heat transfer in soils, are presented in this Special Issue. Although the submissions for this Special Issue have been closed, more in-depth research in the field of soil pollution and the geotechnical environment continues to address the challenges we face today, such as soil pollution mechanisms, pollutant migration, and the remediation efficiency of pollutants.

Thanks to all the authors and peer reviewers for their valuable contributions to this the Special Issue, "Advances in Soil Pollution and the Geotechnical Environment". I would also like to express my gratitude to all the staff and people involved in the creation of this Special Issue.
