H14E:
Nonpoint Source Flux Impact on Groundwater, Vadose Zone, and Surface Waters: Assessments, Mechanisms, and Control Strategies II


Session ID#: 10606

Session Description:
Nonpoint source (NPS) fluxes in vadose zone, groundwater, and at their interface to surface water are critical to pressing societal issues including agricultural sustainability, food security, drinking water quality, ecosystem health, and global change.  Better understanding is needed of bio/geo/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 fate of NPS fluxes and to more effectively control sources and perform remediation. We invite contributions assessing processes and mass fluxes in the subsurface and at the subsurface-surface interface using field, laboratory, and modeling approaches (lab, plot, or watershed/(sub)basin scale); presentations on innovative approaches to control or remediate NPS pollution in urban, agricultural, and forest watersheds/groundwater basins; and on studies that address linkages between chemical, biological, hydro(geo)logical, and/or social factors, or studies linking agricultural practices to NPS fluxes to develop sustainable management options.
