Division of Groundwater and Soil Environment (DGSE) aims at the national strategic requirements and the cutting-edge international research on groundwater and soil environment. We conduct original and strategic research in theory and technology of groundwater and site contamination control and remediation, water resource utilization and protection, and poor-quality groundwater treatment etc., and mainly focus on describing the eco-geochemistry cycle process of elements, fate and/or transport of contaminants in groundwater, and developing the methodology of related ecotoxicity and risk assessment, as well as environment functional materials and facilities for groundwater and soil pollution control, and drafting the technological standard and specification for assessment and remediation on contaminated sites. Our objectives are to provide technical support to the scientific decision-making and promote the improvement of groundwater and soil environmental quality via multidisciplinary effort in China.
