An important hidden source of soil heavy metal pollution was the discharge of wastewater and waste rock during mining production activities. Numerous processes could result in the buildup of heavy metals in soil, and exposure to these metals could irreversibly harm a person's health. The source, distribution and quantity of historical waste residue in a pyrite mining area were described, and the nature of the waste residue was determined based on the results of toxic leaching identification in this study. The study showed that the pH value of the leaching solution of the waste residues was less than 6. Therefore, these waste residues was the second category of general industrial solid waste. The soil around the waste residues was basically acidic. Also, the content of arsenic, cadmium and copper in farmland soil around the waste residues exceeded the screening value in the Soil Environmental Quality Standard Risk Control of Soil Pollution in Farmland (GB15618-2018). Therefore, the arsenic, cadmium and copper in the waste residue could migrate with rainwater and cause some pollution to the neighboring farmland soil. The surface water was acidic and the arsenic concentration in the surface water exceeded the standard limit. Therefore, surface water was affected by acidic wastewater. However, the impact of project wastewater on groundwater was not significant. Through the analysis of the pollution status, comprehensive treatment countermeasures and secondary pollution prevention measures for the waste residue were proposed, as well as the issues

“…Although laboratory simulation and field investigation methods can help to understand the migration and transformation process of pollutants and the identification and analysis of pollution sources [12][13][14][15][16], they cannot reproduce the pollution process of heavy metals in soil. At present, numerical simulation is mainly used to predict and evaluate the migration and transformation process of pollutants in groundwater [17][18][19][20].…”

Identifying the source and impact pathways of soil heavy-metal pollution is critical for its assessment and remediation. Numerical simulation has been widely used to simulate soil heavy-metal pollution processes and predict risks. However, traditional numerical simulation software requires a large number of parameters, which are difficult to obtain in site-scale studies. This study proposes a rapid method for identifying soil heavy-metal pollution processes using the TOUGH2/EOS7 software. It has automatic calibration and uncertainty analysis capabilities, which can effectively reduce the demand for parameters. This study established a method, including model selection, simulation, validation, and error analysis, to verify the effectiveness of the proposed method. This study identified the most realistic scenario for chromium pollution and simulated its release over 20 years, and the results met accuracy requirements with a best-case fit of 0.9998. The results showed that the method can quickly identify the source and impact pathways of soil heavy-metal pollution, providing strong evidence for environmental damage assessment.
