Abstract

Abstract

Aiming at the difficult problems of determining the target value of groundwater risk management and control, this article took an abandoned ferroalloy plant as the research object, and discussed the environmental impact of hexavalent chromium pollution in groundwater on the downstream sensitive target rivers. Numerical simulation methods were used to determine the pollution under hydraulic interception conditions, the target value of groundwater risk management and control of the plot. The results showed that:under natural conditions, after 2500 days, the pollution plume with hexavalent chromium concentration greater than 0.5 mg/L will migrate to the river; under hydraulic interception condition, when the hydraulic interception of the hexavalent chromium concentration was above 10 mg/L of the pollution plume, the highest concentration of hexavalent chromium discharged to the river was 0.46 mg/L, achieving the purpose of groundwater risk management and control. It's finally determined that the groundwater risk control value of this site was 10 mg/L, which reduced the area of groundwater risk control by about 9.45 m² and saved the cost of sewage treatment. This study provides support for determining the target value of groundwater risk management and control, and preparation of groundwater remediation plans for contaminated land in China.
