Modeling Agricultural Nonpoint Source Nutrient Pollution Transport in a Mountain Wetland Complex, New Zealand.  University of Canterbury and Department of Conservation.  Evaluating and modeling the transport and effects of diffuse  nutrient pollution from agricultural land use intensification in a high country mountain catchment (Lake Clearwater) in the Ashburton Lakes Basin.  Implemented a comprehensive monitoring program for flow and water quality for ephemeral and perennial streams, wetlands and a shallow lake; evaluating surface-groundwater interactions; developing water and contaminant mass balance models; and applying and testing the Catchment Land Use for Environmental Sustainability (CLUES) and Soil and Water Analysis Tool (SWAT) models for the catchment.  Using results and making recommendations to aid wetland conservation and restoration efforts in high country tussock grassland environments.



US EPA Region 8 Watershed/Nonpoint Source Pollution Program Management.  Managed watershed and nonpoint source (NPS) pollution management programs for tribal lands throughout EPA Region 8.  This included working collaboratively with 27 tribal nations and reservations to provide grant funding, develop watershed and NPS pollution management plans, monitor and assess surface waters, develop water quality standards and total maximum daily loads, design and implement best management practices, and develop comprehensive reports.  Led the development of a Strategic Plan, annual work plans, and a database for all NPS pollution management activities.  Coordinated regional and national training workshops, conferences, and outreach to provide technical assistance to tribes.  Worked with other US EPA regions, national offices, and other agencies to manage and improve the Watershed/NPS Pollution Management Program.
