Microbe Transport in Porous Media for Soil Improvement and Human Health Protection
We commonly expect that sand filters, and natural soil will filter out microbes in our soil and ground water. However microbes are small enough to move through soil, and fractured rock, if the medium has a high permeability, that is, has large enough pores. Soil and rock formations used for drinking water supply are always chosen because they have a high permeability, so that it is easy to pump water from them. Therefore this research on the transport of microbes in soil or rock aquifer formations is important for drinking water protection. The specific goal of this research is to learn about basic transport mechanisms to prevent microbe transport when protecting drinking water, and to enhance microbe transport for beneficial applications. The beneficial application explored in this research is production of calcium carbonate, and other
minerals, to cement soil and make it stronger.
