Surfactants are widely used for various purposes in industry, but for many years were mainly
chemically synthesized. It has only been in the past few decades that biological surface …

The immense diversity of microbial life found in the vadose zone reflects the extremely
heterogeneous and highly dynamic aquatic and chemical environments formed within soil …

Properly designed biological filters or infiltration systems have the capacity to significantly
reduce effluent concentrations of pathogenic microorganisms in wastewater. The retention …

An understanding of the transport and survival of microbial pathogens (pathogens hereafter)
in agricultural settings is needed to assess the risk of pathogen contamination to water and …

This is a review of physical, chemical, and biological processes governing microbial
transport in the saturated subsurface. We begin with the conceptual models of the biophase …

We review the application of mathematical modeling to understanding the behavior of
populations of chemotactic bacteria. The application of continuum mathematical models, in …

Written by leading soil and ground-water remediation scientists, Handbook of
Bioremediation presents information regarding the processes, application, and limitations of …

Resting-cell suspensions of bacteria isolated from groundwater were added as a pulse to
the tops of columns of clean quartz sand. An artificial groundwater solution (AGW) was …

Microorganisms migrating into and through soil from sources on the land surface may cause
a serious threat to both ground and surface waters. It has been estimated that …

The following sections summarize the major topics involved in in situ bioremediation of
soluble phase (dissolved) chlorinated solvents in groundwater. This introduction is designed …
