Rounded Rectangle: Home As production and use of biofuels (ethanol, gasohols, biodiesels, etc.) increase, releases of biofuels to the environment will become more prevalent. Biofuels, like traditional fuels, are a mixture of many components, some of which are likely to have minimal impact on soil and groundwater while others may, in some cases, present more significant environmental challenges. Our overall goals are to understand which components present the most significant risks under various soil and groundwater conditions, to develop approaches to monitor groundwater impacts of and the microbial responses to the biofuel releases, and to develop and test methods for minimizing or completely remediating groundwater impacts of biofuels.  Our research group has been studying the environmental fate of biofuel components since 2002, including modeling, laboratory and field research as discussed in more detail in the RESEARCH pages of this website. The images on this page illustrate some of our group’s research topics, approaches, and results. Our research is field-based, including controlled field experiments, with modeling and laboratory studies closely tied to our field investigations.
