We invite contributions from diverse fields related to the fate, transport and remediation of contaminants in the saturated zone, vadose zone and/or the interaction of surface water and groundwater. We welcome studies on emerging contaminants such as PFAS, microplastics, pharmaceuticals, and pathogens, as well as legacy pollutants such as metals and organic compounds. We also encourage work examining contaminant interactions arising from anthropogenic activities, including the behavior of greenhouse gases, gas migration, and volatile compounds within these systems. Studies based on laboratory experiments, field tests, numerical simulations or advanced computational models, including machine learning techniques, are welcome. Applied investigations focused on the design and assessment of remediation strategies and use of innovative monitoring and detection tools are also welcome. We hope to explore the integration of contaminant transport and remediation with solutions to climate change, sustainable energy systems, and resource management. This session will provide an overview of contaminant transport and remediation across a broad range of topics to encourage interactions amongst members of the hydrogeology community.
