Abstract:
The identification and rectification of soil contamination hazards are essential legal obligations for key soil pollution supervision and management entities. These actions support soil pollution prevention and source control, and promote the improvement of soil environmental quality at industrial sites. However, in China, this process is still in its early stages, the existing standard system is incomplete, and there is still room for improvement in work effectiveness. This paper systematically reviews the current status and policy revelations concerning soil pollution prevention for domestic and international enterprises, focusing on relevant regulations and standard systems. It also summarizes the historical development and practical experience in the formulation of technical standards for identifying and rectifying soil contamination hazards as well as exploring quality management. China has made progress in establishing technical and quality management systems for identifying and rectifying soil contamination hazards. However, there are still several key issues such as insufficient focus on the issue, overlap with safe production requirements, incomplete identification (especially in leakage detection and real-time monitoring of concealed key facilities and equipment), lack of rectification standards in key industries and inadequate internal and external quality supervision measures. To address these challenges, the author proposes three key suggestions: (1) Emphasize the importance of hazard identification. (2) Construct a technical system for identification and rectification that includes ‘1 general guideline + N industry-specific identification guidelines + X guidelines for key facility leakage identification + Y rectification engineering technical specification for key industries’. (3) Enhance both internal motivation and external constraints to improve the quality supervision system. These measures aim to provide robust technical standards and quality supervision for soil pollution prevention, source control, and prevention of new contamination.
