Conduct laboratory, lysimeter and field experiments to examine the important physical, chemical, and biological processes affecting the fate and transport of pathogenic microorganisms in manure-soil-water systems. Laboratory studies will determine the important processes and mechanisms affecting pathogen survival. Studies will be conducted at various scales using culture and molecular approaches to investigate pathogen movement in surface water and soil. Measurements of pathogen concentration, soil and environmental conditions will be collected to allow the simulation of pathogen transport. As new information becomes available, existing models will be improved to enhance the prediction of pathogen transport to surface water, ground water, and the environment. Coupling laboratory and field scale experiments with simulation studies, new strategies will be developed to control the movement of pathogenic microorganisms from animal feeding operations to human food and the environment. Research will be conducted in collaboration with the Food Safety Research, WRRC, Albany, CA. 5310-42000-002-00D (5/01).
