Session Proposal: Improving Water Quality Requires Understanding Processes at Groundwater-Surface Water Interfaces: Implications for Sustaining/Restoring/Maintaining Aquatic Ecosystem Health (AGU25)

H087
Improving Water Quality Requires Understanding Processes at Groundwater-Surface Water Interfaces: Implications for Sustaining/Restoring/Maintaining Aquatic Ecosystem Health

Session ID#: 249205

Session Description:
Groundwater – surface water interfaces represent hotspots of environmental pollution where contaminants from rivers, lakes and coastal waters meet and interact with groundwater contaminants. They are mixing zones for complex cocktails of legacy and emerging pollutants derived from various point to non-point sources. Environmental pollution risks at groundwater – surface water interfaces are affected by temporal dynamics of surface water pollutants interacting with heterogeneous patterns of pollutants in the subsurface. The mechanisms controlling the activation and transport of different types of pollutants and the impacts of human interventions, land use and water management are still poorly understood. This session invites contributions that: Develop innovative approaches and technologies for identifying legacy and emerging pollutants that interact across groundwater-surface water interfaces Reveal temporal dynamics and spatial patterns of drivers and controls on contaminants in surface waters and groundwaters Demonstrate the efficiency of integrated groundwater and surface water pollution control and remediation strategies
