Main Technical Content: 7. Key Areas of Site Soil and Groundwater in Heavy Metal Migration Risk Assessment, Control, and Remediation Strategies 7.1 General Principles The general principles are as follows: (1) Referring to the "Opinions on Further Strengthening the Prevention and Control of Heavy Metal Pollution" issued by the Ministry of Ecology and Environment, based on the types of heavy metal-related industries in the four key areas, develop a risk assessment strategy for heavy metal migration in soil at key area sites (see Figure 3 for the assessment process). Figure 3: Risk Assessment Process for Heavy Metal Migration in Soil at Key Area Sites (2) During the risk assessment process for heavy metal migration in soil at key area sites, appropriately increase the sampling areas, number of sampling points, sampling depths, and detection factors in the investigation phase for three key industries: electroplating in the Yangtze River Delta, chemical industries in the Beijing-Tianjin-Hebei region, and non-ferrous smelting in the Changsha-Zhuzhou-Xiangtan region. (3) Based on the migration risk level of heavy metal pollution and the hydrological and geological characteristics of the sites in the key areas, select targeted control measures (see Table 1) to develop risk control and remediation strategies for heavy metal migration in soil and groundwater at the sites. Table 1: Risk Control and Remediation Techniques for Heavy Metal Migration in Soil and Groundwater at Key Area Sites 7.2 Yangtze River Delta Region 7.2.1 Risk Assessment Strategy for Heavy Metal Migration at Electroplating Sites According to the types of electroplating industries and heavy metal pollution characteristics in the Yangtze River Delta region, the specific sites are divided into high-, medium-, and low-risk sites for heavy metal migration, and corresponding risk assessment strategies are developed, as shown in Figure 4. Note: a) Significantly increase the number of sampli
