John Wilson, Microbiologist
Dr. Wilson is a Research Microbiologist in GWERD’s Subsurface Remediation Branch. He holds a B.S. in Biology from Baylor University, an M.A. in Microbiology from the University of California at Berkeley, and a Ph.D. in Microbiology from Cornell University. His research areas are permeable reactive barriers, monitored natural attenuation, fuel oxygenates, and biofuels.
Dr. Wilson leads research dealing with biological and non-biological processes that destroy contaminants in groundwater. The research is applied to active remedial technology and to monitored natural attenuation. Recent research is directed to:
- Understanding the role of reactive iron and sulfur minerals in degradation of halogenated hydrocarbons in plant mulch-based passive reactive barriers (biowalls) and in aquifer sediments
- Evaluating the prospects for natural degradation of ethylene dibromide and 1,2- dichloroethane in groundwater from legacy spills of leaded gasoline
- Evaluating the prospects for biodegradation of the fuel oxygenates methy tertiary butyl ether and tertiary butyl alcohol from gasoline spills
- Predicting the biodegradation of biofuels (ethanol, biodiesel, butanol, propanol, isopropanol) in groundwater and their impact on the natural attenuation of benzene from fuel spills
Dr. Wilson leads efforts in EPA to apply the analysis of stable isotopes to understand the degradation of organic compounds in groundwater. Dr. Wilson provides training and technical assistance to EPA’s regions and to state agencies on natural attenuation of chlorinated solvents and fuel components in groundwater.
