ABSTRACT
The objective of this chapter is to present the basic principles and concepts of groundwater microbiology and transport processes as they relate to biodegradation. Understanding of these processes is necessary to model, forecast, and manipulate subsurface contaminant transport and biodegradation. The basic principles presented may be applied to the biorestoration of contaminated groundwater, a field now commonly called “bioremediation” (Lee et al., 1988; National Research Council 1993; Thomas and Ward 1989).
