Biodegradation is an important mechanism for contaminant reduction in groundwater environments; in fact, in-situ bioremediation and bioaugmentation methods represent alternatives to traditional methods such as pump-and-treat. Chemotaxis has shown to enhance bacterial transport toward or away from concentration gradients of chemical species in laboratory experiments and can signifficantly increase contaminant flux undergoing degradation at the interfaces of lowand high-permeability regions. In this work, the method of volume averaging is used to upscale the microscale description of chemotactic microbial transport in order to obtain the corresponding macroscale equations for bacteria and the attractant. As a first apprach, cellular growth/death and consumption …
