The Food-Water Link and Nonpoint Source Flux Impact on Groundwater, Vadose Zone, and Surface Water Quality

Session ID#: 77933

Session Description:
Nonpoint source (NPS) fluxes in vadose zone, groundwater, and at their interface to surface water are critical to societal issues including agricultural sustainability, food security, drinking water quality, ecosystem health, and global change.  Better understanding is needed of bio/geo/hydro/chemical and anthropogenic factors affecting diffuse mass fluxes of nutrients, pesticides, emerging contaminants, trace elements, greenhouse gases and other chemical/biological agents. Strategies are emerging to monitor the sources and fate of NPS fluxes and to more effectively control and remediate water quality. We invite contributions assessing NPS transport processes and flow routes using field, laboratory, and modeling approaches (lab, plot, or watershed/(sub)basin scale); presentations on innovative remediation options to control or intercept NPS pollution in rural or urban settings; on studies that address linkages between chemical, biological, hydro(geo)logical, climatological, and/or social factors affecting NPS fluxes, and on studies linking agricultural practices to NPS fluxes to develop sustainable management options.
