Key Technologies and Equipment for Contaminated Surface/Groundwater Environment in the Rural River Network Area of China: Integrated Remediation

Abstract In eastern China, the rural river network area (RRNA) is an anthropic active area characterized by its rapid economic development and high gross national product. However, the water environmental pollution in these areas is increasingly severe, which has greatly hindered its sustainable development. Especially, the frequent interactions between surface/groundwater (SW-GW) have intensified the pollution migration and transformation in RRNA. Therefore, an integrated remediation in rural river network area project (IR-RRNA) has been launched, funded by the Ministry of Science and Technology of the People’s Republic of China, to realize the integrated remediation of SW/GW and soil in RRNA. The IR-RRNA (2019–2022) will apply the related interdisciplinary and methodological knowledge to elucidate the transportation and transformation of pollutants in water and soil during SW-GW interaction, and develop key remediation technologies of surface water, groundwater, and soil suitable for the RRNA. By this way, we attempt to realize the remediation technologies integration for surface/groundwater and soil in RRNA and implementing application demonstration. Meanwhile, a technical guideline will be compiled for the integrated remediation suitable for the RRNA. This project is conducive to addressing the urgent environmental problems of RRNA, and promoting the rural economic revitalization and ecological environment optimization.
