|Statement of Research
The purpose of the research is to discover, evaluate, and integrate knowledge about transport and fate of enteric pathogenic microorganisms affecting microbial quality of irrigation waters. New hypotheses and measurement strategies have to be developed to evaluate and quantify biological, chemical and physical factors and interactions affecting pathogen prevalence, fate and transport in irrigation waters. The research uses hydrologic and contaminant transport modeling, soil-landscape analysis, scaling methods, data mining, geographic information systems, and other relevant technologies to integrate pathogen fate and transport information in pathogen fate and transport models for development, evaluation, comparison, and selection of management practices to reduce or eliminate risk of preharvest microbial contamination of foods.
