Julie Chambon Publishes Articles Examining Bioremediation Methods

Julie Chambon, Ph.D., a senior staff engineer based in California, is the lead author and co-author of two articles published this fall examining a range of methods used to remediate impacted sites, including reductive dechlorination.

Dr. Chambon is the lead author of an article for Biotechnology and Engineering entitled, "Review of Reactive Kinetic Models Describing Reductive Dechlorination of Chlorinated Ethenes in Soil and Groundwater." It examines the modeling approaches used to measure the process of reductive dechlorination, a bioremediation technique that uses microbes to degrade solvents found in subsurface environments. Her article also examines the experimental data needed to calibrate such models and the development of practical modeling tools for use in field applications.

Dr. Chambon also is a contributing author in a second article appearing this fall in the Journal of Environmental Management. That article, "Is There An Environmental Benefit from Remediation of a Contaminated Site?," assesses the risk reduction and life cycle impacts of four types of remediation options. Enhanced reductive dechlorination and long-term monitoring are identified as remediation scenarios with the lowest secondary life cycle impacts, making them preferred remediation alternatives among the four options examined.

After completing her doctoral studies this year at the Technical University of Denmark, Dr. Chambon joined Geosyntec in Oakland, where she focuses on soil and groundwater remediation and the development of modeling tools for assessing bioremediation performance. She brings to Geosyntec a deep understanding of bioremediation, modeling, and site assessment methods that further bolsters the firm's ability to effectively serve public and private sector clients.
