Nonpoint Source Pollution Dynamics, Impacts, Management, Control and Regulatory Efforts in Groundwater and Vadose Zone Systems
Session ID#: 251384
Session Description:
Nonpoint source (NPS) fluxes in the vadose zone, groundwater, and at their interface with surface water are critical to issues such as agricultural sustainability, food security, drinking water quality, ecosystem health, and global change. This session encourages interdisciplinary dialogue on bio/geo/hydro/chemical and anthropogenic factors influencing diffuse fluxes of nutrients, pesticides, emerging contaminants, trace elements, greenhouse gases, and other agents. Strategies are emerging to monitor sources and fate of NPS fluxes and improve groundwater quality management. We invite contributions assessing NPS transport and flow using field, laboratory, or/and modeling approaches; presentations on innovative remediation to intercept NPS pollution in rural or urban settings; studies linking chemical, biological, hydro(geo)logical, climatological, and/or social drivers with impacts on water and ecosystems; monitoring approaches to evaluate NPS fluxes; studies connecting agricultural practices to NPS transport for sustainable management; and outreach, legal, or regulatory efforts to control NPS pollution of groundwater and groundwater-fed surface waters.
