Location: Contaminant Fate and Transport Research
Project Number: 2036-32000-003-03-S
Project Type: Specific Cooperative Agreement
Start Date: Sep 3, 2009
End Date: Sep 2, 2014
The overall objective of this project is to improve our understanding of and ability to predict the transport and fate of pathogenic microorganisms at various spatial scales (from pore to plot scale).
Laboratory experiments will be designed to test specific hypotheses with regard to mechanisms controlling pathogen transport and fate in the environment. The specific experimental approaches and techniques will depend on the research question. For example, we may use measurements of electrophoretic mobility, hydrophobicity, surface charge density, enzyme treatment, FTIR, and TEM imaging to examine surface properties of pathogens that influence their interaction in the environment. We may use batch, micromodel systems, DLVO calculations, pore-scale flow and transport simulation techniques, and saturated and unsaturated column experiments to examine mechanisms of pathogen transport, retention, and survival. Information collected from laboratory studies will be used to refine and improve the predictions of models for pathogen transport and fate. Existing models for pathogen transport and survival will be modified to simulate field scale behavior. Documents SCA with UC Riverside. Formerly 5310-32000-002-10S(8/11/11).
