Effect of reactive amendments to improve performance of biowalls for remediation of TCE

Principal Investigator(s) 

This project is consists of a series of experiments to determine which of several mixtures of organic and inorganic materials will create the best biowall to be implemented to remediate TCE (an industrial solvent) contamination in groundwater. In contrast to traditional pump and treat methods, in situ remediation with a biowall (a permeable reactive barrier) could be cheaper and have the desired environmental protection. Biowalls are constructed down gradient of the dissolved contaminated area, and they depend on the groundwater gradient to transport the contaminant through the biowall, where treatment occurs. Results of the biowall tests will be used to design a site implementation plan using the best biowall matrix. More information about this project is available online.
